A NEW SPECIES OF CEROPLATUS
(DIPTERA, MYCETOPHILIDE)
Amherst, Massachusetts
In September 1940, Dr. C. P. Alexander collected a speci- men of an undescribed species of Ceroplatus on the steps of Fernald Hall at Massachusetts State College. In view of the fact that the insect was taken at Fernald Hall it was felt that species should be dedicated to the Fernalds, father and son, who founded and developed the Department of Entomology at Massachusetts State College. I take pleasure in naming this insect, Ceroplatus fernaldi, in honor of Pro- fessors Charles Henry and Henry Torsey Fernald. Ceroplatus fernaldi n. sp.
Length 8 mm. General color dark brown.
Head. Vertex and occiput brown. Frons and palpi yel- low. Antennae brown.
Thorax.
Notum and pleurae of prothorax dark brown. Mesonotum dark brown with 3 black stripes which unite in front of the scutellum. Humeri yellow. Scutellum and pleurae brown. Hypopleurae with setae.
Wing. 5% mm. in length. Sc, long ending about the dis- tance from the humeral crossvein to the base of Rs beyond the origin of R̤ Sc, opposite the humeral crossvein. A dark brown spot covers R. and extends along RE. Fused
portion of media and radius about one third longer than the petiole of media. Veins Mi + 2, Ma, Cu, and 2A all fail to reach the margin of the wing. Haltere yellow with a brown knob.
Legs. Prothoracic coxa brown at base, distal two thirds yellow. Trochanter yellow. Femur with a narrow brown Wontribution from the Department of Entomology, Massachusetts State College, Amherst, Massachusetts.

19411 New Species of Ceroplaius 21
band at base, remainder is yellow.
Tibia and basi tarsus
yellow.
Tibia about .7 as long as the basi tarsus. Remain- der of tarsus appears dark because of presence of setulse. Coxa of mesothoracic leg yellow except for brown band on the outer anterior surface and a narrow black stripe at the distal portion. Trochanter yellow. Femur with a narrow brown band at the base, the remainder yellow. Tibia and tarsi yellow but covered with black setulse. Coxa of meta- thoracic leg resembles that of the mesothoracic leg except that the brown area is larger. The rest of the leg is the same in appearance as the mesothoracic appendage. Abdomen. Dorsum of segment one entirely dark brown. Segments two through five have the dorsum dark brown except for a posterior lateral yellow spot on either side. Ventral portion of abdomen yellow. Hypopygium dark brown, resembles somewhat that of Ceroplatus militaris Johannsen. It can be distinguished from that of Johann- sen's species by the lack of dense clusters of black setae on the inner and dorsal surfaces of the base of the disti-style. This new species would run to Ceroplatus militaå´n in Johannsen's key. It can be distinguished from militaris by the structure of the hypopygium, as already discussed; by the relative lengths of the fused portion of veins M and R and the petiole of media ; and by the markings. Described from one male taken in September 1940, at Fernald Hall, Massachusetts State College, Amherst, Massa- chusetts by Dr. C. P. Alexander. Type in my collection.
