NEW SPECIES OF ASILIDE FROM SOUTHERN
CALIFORNIA?
BY FRANK R. COLE,
Scientific Assistant, Bureau of Entomology, U. S. Department of Agriculture.
The species described in this article were all collected in San Bernardino County, California.
There are many asilids in this
region, and no great amount of collecting has been done since Co- quillett worked over this section. Any extensive collecting is certain to bring to light new forms. In traveling only a short distance here, one will encounter a great variety of ecological conditions. There are many flowers at all seasons of the year and the mild climate permits of almost uninterrupted collecting. In the preparation of this paper the writer is indebted to Mr. Fred- erick Knab for the use of the National Museum collection, which contains much valuable type material in this group. Cophura highlandica sp. nov. (Plate VIII, fig. 4). 9. Length, 7 mm. Head yellowish gray pruinose. Body black, mostly hidden by pollen.
Front yellowish gray pollinose.
Face gently convex.
Mystax white and extending nearly to the antennae.
First joint of antenna slightly longer and more slender than second. Third joint four times as long as second, and slender. Style not very slender, rounded at end.
Thorax gray and light
brown pruinose.
Two dark brown vittse, broad in front and nar- rowed behind. Thorax very convex. A shining black spot above supra-alar groove and two of the same size just in front of 1 Published by permission of the Secretary of Agriculture. Pu&e 2363-68 ( 1916). hup ttpsychu einclub orgt23t23-061 html

the scutellum. Border of scutellum gray pruinose, yellowish in center. Abdomen yellowish gray pruinose, hind margins of all except last segment polished black, the last three narrowly. An- terior third of second segment polished black. Second, third,
fourth, fifth, and sixth segments with a black spot on each side. The gray pruinose fasciae on all the segments vary in size and shape, in all but the last segment running almost to the median line. The
gray pruinose spots on the seventh segment are confined to the lateral margin. Meso, sterno, and pteropleurae bare, and gray pruinose with golden brown spots.
Scutellum rounded and with a
subapical pair of stout bristles.
Femora black, the tips of the
middle and hind ones being gray pruinose in front. Knees dark
reddish brown. Tibiae and tarsi dark reddish brown. Legs very much darker beneath. White hairs on legs quite thick, the bristles strong and either brown or white. Halteres grayish brown, lighter at tip and base. Supra-alars reddish yellow, the rest of the thoracic bristles black. Antenna1 style about one third as long as third joint. Mystax mixed yellow and white. In two
specimens the front pair of dorso centrals are partly reddish. Wings hyaline.
Broad brown spots at base of discal, posterior and submarginal cells. Tip of wing brown. Genitalia polished black.
Type-U. S. N. M., Cat. No. 20184. Several paratypes in author's collection.
Habitat-East Highlands, Cal., February, 1915. This species is quite close to punctipennis Coq ., but the markings 'differ, and the spots of the wing are darker and more distinct. In punctipennis the tip of the wing is hyaline, and the base of the marginal cell has no brown color.
The thoracic and scutellar
bristles of pictum are black, those of punctipennis are yellowish. 'The tarsi of pictum are darker, and the knees black. In punc- .tipennis the knees are red and the gray pruinose fasciae on the ab- domen are broader. A number of specimens of this new species were collected, most of the material being in the author's collec- tion in California and not available for study. These small flies were collected on the dead twigs of sage brush (Salvia mellifera) and the wild alfalfa (Lotus glaber) so common in Southern Cali- iornia, and are not very quick on the wing.

tennae.
Face and front flat and thickly brown and silvery gray pollinose.
Two rows of long reddish brown bristles on oral mar- gin, a few long white hairs above, extending to antennae. Ocellar bristles brown. Cilia of posterior orbit brown. Antennae black, gray pruinose. First two joints of antennae with brown bristles. One strong bristle beneath second joint. Third joint flat and
slightly longer than first two joints together. Style rather slender
acuminate, and less than half as long as third segment. Post-
alars and supra-alars quite long and brown in color. White pile
on scutellum and just in front of.
Legs medium slender, rounded.
Tibiae and tarsi very spinose. Femora hairy. Hind metatarsi with many short strong spines beneath.
Hind femora slender on
basal two-thirds and with a club-like thickening toward the end. Hind tarsi thick and heavy. Metatarsus almost as long as three following joints. Legs reddish yellow, the tarsi dark brown dis- tally. Front femora dark brown. Bristles of legs reddish yellow and pile white. Wings elongate and variegated with blackish brown, basal third being hyaline. Tip of anal cell blackish, pos- terior cells in part blackish.
Fifth posterior cell all black.
Hya-
line spot in marginal cell. Discal cell all dark. Type-U. S. N. M., Cat. No. 20200.
Habitat-Redlands, Cal., April, 1914.
There are three paratypes in the U. S. N . M. collection. These are all males.
Two are labeled "Los Angeles Co., Cal., Co- quillett," and in these the abdomen is more of a reddish color than in the type. The other specimen is labeled "September, Los Angeles Co., Cal." and is smaller and lighter in color than the others, the abdomen being yellow. These specimens are probably faded to some extent but agree very well with the type. As in the described specimen the venter is brown with silvery pollinose areas, and is thickly dotted with small dark brown spots. The wings are marked as in the type but are more of a brownish color. The type was taken on a sandy plot of ground in the foothills south of Redlands, Cal.
This species is quite close to abdominalis, but does not have the tinge of red on the thorax. The last segment of the abdomen is narrower, and the bluish black color of the abdomen is confined to the base of the first and second segments. In lorn; the brown of
the wings is cut off sharply and does not spread into the basal
