268 DIPTERA 
slightly porrect; no vertical bristles, a single pair of small ocellar bristles, lower occiput bearded with 
white hairs. Thorax bare except for a single pair of strongsupraalar bristles. Pygidium large, reflexed 
over the abdomen, bare and closed. Front cox: much longer than the posterior pairs, legs slender, 
front femora somewhat thickened. "Wings cuneiform, no axillar lobe, costa continuing around the hind 
margin, hairy, humeral crossvein present, first vein short, second vein long, third vein not forked, ending 
at the tip of the wing, pedicel of the second and third veins arising from the middle of the first basal 
cell, discal cell open outwardly the fourth vein forked, anal cell large, in length slightly shorter than the 
second basal, but in breadth three times as wide as the second basal and extending to the hind margin 
of the wing, the anal vein fused with the fimbriate hind margin. 
Type species : C. curvaía, Becker. The preceding generic description has been furnished 
mainly by the detailed description of C. fictipenmis, Bezzi. Bezzi provisionally placed his species in 
Chelipoda, from which it differs in the enlarged basal cells, the long level occiput, the lack of vertical and 
discal bristles and the bifasciate wings. The genotype has the wings uniformly yellowish.

Characters. — Elongate, opaque black, cinereous pruinose species with yellow legs, the 
front coxz elongate. the front femora raptorial, the antennz lengthened and with plumose arista, 
the neuration quite as in Chelifoda, and the anterior legs of the male deformed. ^ Head round, 
eyes broadly separated above, two ocellar and two vertical bristles which are robust but short; face 
narrower than the front; proboscis short, palpi small and yellow; antennz greatly lengthened, first 
joint long, obconic, three times the length of the spherical second joint, third joint pyriform, as long as 
the first joint, bearing a thick apical arista nearly as long as the antenna and which is heavily plumose 
below. Thorax a little longer than the abdomen, front legs placed up toward the head, distant from the 
posterior pairs which are close together, scutellum very small, metanotum well developed ; one humeral, 
one prescutellar dorsocentral, one supraalar and two small scutellar bristles present; metapleure with 
three or four hairs. Abdomen compressed, with short hairs, pygidium strongly compressed, upper 
lamelle rounded. Front coxe subequal to the femora in length, armed with black subapical tubercle 
and with a row of setz, front femora incrassate, raptorial, denticulate and setose beneath and with cilia 
above, posterior femora without sete, middle tibiz incurved, apically dilated and with long hairs and 
subapical pencil on the extensor side, middle metatarsi tuberculate above, tarsal claws small. Wings 
cuneate, no costal bristle, no stigma, third vein not furcate, discal cell complete, posterior cells sessile, 
anal cell rounded apically and as long as the second basal. According to Dr. Bezzi's figure the basal 
half of the costa bears outstanding hairs and the vein in front of the anal cell is setose. 
The type species, P. Biroi, is the only known form of this remarkable genus. It was collected in 
New South Wales, Australia,
