Psyche 
[March- June 
Crepidomyia darlingtoni n. sp. 
Related to trier epis Shannon but very distinct in the smoky 
wing apex. 
Male. Length 14 mm.; wing 10.8 mm. Head: rather short and 
therefore wide and flat; the eyes are large, conspicuous, bare, the 
anterior facets slightly enlarged above, touching only a short dis- 
tance. Vertical triangle obscurely shining black and long, erect 
black pilose. Upper third of occiput black and black pilose. The 
whole of the flat front totally obscured by thick, microscopic, 
brilliant, golden pubescence. Face strongly carinate with a 
lateral ridge or keel reaching from eye margins of epistoma slightly 
concave anteriorly along the lateral keels and this broad shallow 
concave area is covered by pale brassy pubescence forming a 
broad stripe from the lateral facial strips to the oral margin; re- 
mainder of face shining black; facial strips pale pubescent; cheeks 
shining black. Antennae black, the third joint with brownish 
pubescence, about half again as long as the third joint, gradually 
thickened towards the base, blackish on the basal sixth, re- 
mainder white. Thorax: dull black with a brownish tinge due to 
four very obscure barely discernible vittae; the inner pair are 
shorter, more closely separated, but diverging posteriorly, the 
outer pair reaching to the scutellum. On the extreme anterior 
edge of the mesonotum lying inside the humerus there is an almost 
equilateral triangle of pale shining yellow pubescence. Along the 
dorsal suture, stopping someways from the midline there is a long, 
slender, marginal stripe of yellowish-brown pubescence; upon its 
medial ends and anterior side it curves sharply backwards for a 
little distance. Pile of thorax wholly suberect, black. Scutellum 
shining black with faintly impressed rim, its discal pile black, its 
ventral pile thick, long and pale. Abdomen: moderately long but 
compact, not so wide as thorax, widest at the basal third segment, 
but scarcely less wide either at base or end of fourth segment; 
wholly shining black, the first two segments somewhat flattened, 
the pile everywhere flat-appressed and black except as follows: 
sides of first segment and broadly over the anterior corners of the 
second nearly to the end of the segment of erect pale pile; a small, 
marginal, lateral, subbasal patch of white pile on the third seg- 
ment and a medio-apical patch on the last segment. Legs: chiefly 
shining black, the anterior tibiae distally, greater distal part of the 
middle tibiae dark brownish-black. Anterior basal tarsi dark
