Diptera of Labrador
DIPTERA OF LABRADOR
Boston Society of Natural History
This list was for the most part prepared some time ago, but was laid aside to await the determination of few species. In the meantime, however, other work intervened. The list represents the results of a number of expeditions by zoolo- gists and collectors including Alpheus S. Packard in 1860 and 1864. Samuel Henshaw in 1881, Lucien M. Turner in 3882 and 1883, J. D. Sornborger in 1892 and 1897, A Stecker and J. D. Sornborger in 1899, Dr. C. W. Townsend and G. M. Allen 1906, Owen Bryant 1908 and 0. L. Austin, Jr., 1927. There is also added to the list a number of species more recently described by C. P. Alexander, J. R. Malloch, C. H. Curran, and A. L. Melander, the names of the col- lectors being given in connection with the species described. The following list contains about 170 species. TRICHOCERIDJE

Packard in his Labrador Coast, p. 390, records Micro- myia leucorum with the following note: "Prof. C. W. Woodworth writes me that on examining the collection of Diptera which I made in Labrador, and which is now in the Cambridge Museum, he detected the rare European Ceci- domyid, Micromyia leucorum, belonging to a genus hitherto unrecorded for North America."
I have examined the specimen referred to and thus labeled in the Museum of Comparative Zoology, and find that it is a Chironomid.

Bibio Geoff roy
B. inaequalis Loew 8 Hopedale (Packard). Rama 1899, (Stecker and Sornborger). Cape Charles July 29 and 30 (Allen).
Bibio bryanti sp. nov.
s Head, antennae and palpi black, pile of the eyes long and brown. Thorax black, shining with long black pile. Ab- domen black, whitish pile. Legs reddish, with yellowish hairs, coxae and knees black, the inner spur of the front tibiae about one-half the length of the outer one, the pos- terior tibiae and metatarsi enlarged, the latter about as long as the second and third joint combined. Wings hyaline, the costa, stigma and first and second veins brown. Halteres dark brown. Length 8 mm. Nain, Aug. 18 (Bryant). Rama, Aug. 24 (Sornborger). Holotype and paratypes in the Mu- seum of Comparative Zoology.
It resembles B. variabilis Loew, but the lighter colored femora and enlarged metatarsi readily separates it. From B. fumipennis Walk, it is distinguished by its light colored wings and veins and the noticeably thicker tibise and meta- tarsi.
Bibio labradorensis sp. nov.
s Head, antennae and palpi black, the pile on the eyes brown. Thorax black, shining, pile yellowish. Abdomen black pile yellow. Femora black, tibiae and tarsi yellow, the latter very short, the posterior tibiae as large as the femora and posterior metatarsi about one-half the diameter of the tibia, the second joint of the tarsus also noticeably enlarged. Wings hyaline, the anterior veins and stigma light yellow. Halteres dark brown. Length 5.5 mm. Two specimens. Nain, Aug. 18,1908 (Bryant).
This species resembles a small B. variabilis Loew, but differs in having thickened metatarsi and obsolete stigma. Holotype and paratype in the Musem of Comparative Zoology.

Rama, 1899 (Stecker and Sornborger), Nain (Sorn- borger) , Nain, Aug. 18, 1908 (Bryant).
This circumpolar group of Volucella that live in the nests of various species of Bombus, form an interesting but difficult group to classify. Recognizing but one species with numerous subspecies seems to be the most satisfactory method of treating them.

The species that infests the Barren-ground Caribou (Rangifer articus) is probably the same that frequents the reindeer and is circumboreal in distribution. The adult fly has not been taken. Dr. Grenfell informs me that in all the heads of the caribou that he has examined he found para- sitic larvae usually just below the ethmoid. See Insects of Labrador, in appendix to "Labrador the Country and the People" by Wilfred T. Grenfell, 1909.




================================================================================

140 Psyche [June
Oedemagena tarandi Linn?
This is also probably the same species that infests the reindeer. The larvae are subcutaneous, forming large lumps on the back, from which they escape when full grown through holes in the skin. Dr. Grenfell says that he has seen a skin so perforated that it was practically impossible to cut from it a pair of moccasins. The fly has not been taken in Labrador.
