MYCOMTIA. 73 



and ocellar triangle blackish. Thorax brownish yellow, with 

 short black hairs and stronger bristles. Anterior margin narrowly 

 brown, the colour forming a median stripe, not attaining the hind 

 margin, and also extended laterally from the shoulders. Bristles 

 along sides of dorsum rather strong and numerous, also a strong 

 one on each posterior corner, and a pair on the tip of the scutellum. 

 Pleurae and metanotum brown. Abdomen yellowish, with short 

 black pubescence ; 1st segment all yellow r , remainder with 

 posterior half of each segment black. Genital organs very con- 

 spicuous and peculiar : a high hood-shaped dorsal plate extending 

 downwards at the sides, a slightly curved, very large ventral 

 plate produced at the tip into two long finger-like projections ; 

 a pair of elongate appendages emerge from the inner cavity, 

 bearing oval, lamella-like tips, and below these are traces of a 

 pair of slender finger-like appendages nearly as long.* The 

 whole organ light brownish yellow, pubescent. Leys wholly 

 brownish yellow, pubescent, tips of tarsi darker. Wings pale grey 

 with two brown streaks. The first begins on the costa just before 

 tip of subcosta, running straight across the wing, widening in the 

 middle sufficiently to reach fork of the 4th vein, afterwards 

 narrowing again and finally widening on hind margin. The 

 second begins on the costa just before the tip of the 1st vein, 

 running across the wing to the hind margin, leaving the tip of 

 the wing broadly clear. The sciophiline cell is nearly three times 

 as long as broad, the base of the 3rd vein bisinuate, the cross- 

 vein forming the outer side of the cell broadly suffused. Base of 

 wing slightly brown. Halteres pale yellow. 



Length 4 millim.

28. Mycomyia basalis, sp. nov. (PI. I, fig. 13.) 



<$ . Near M. tinctipennis, Brun. (infra). Thorax : dorsum brown- 

 ish yellow, with some long yellow hairs and black bristly ones. Two 

 dorso-central rows of black bristly hairs, of which at least the 

 hinder three pairs are of larger size than the majority of those 

 scattered over the dorsum. Two strong bristles on posterior 

 corners, others irregularly placed on lateral margins, around the 

 base of the wing, and a pair of rather strong apical ones on the 

 scutellum. Abdomen with the first segment bright yellow, 4th 

 dull yellowish ; remainder black, with barely perceptible hind 

 margins. Belly mainly yellowish. Genitalia large and conspicuous, 

 brownish yellow, pubescent ; a very short dorsal plate, as wide as 

 the ultimate abdominal segment, under which it is nearly hidden ; 



These are not shown in the figure.
