Front with a large deltoid mark laterad of antennae, a round dot be- 

 low anterior ocellus and a dot at base of vertical bristles, black, leaving 

 narrow orbits and oblique stripe from vertical angles to antennae 

 cinereous ; narrow facial and buccal orbits silvery white, complete 

 parafacial groove narrowly brown; median area yellowish white prui- 

 nose. Occiput black below. Antennae brown except inferior half of 

 third joint. 



Mesonotum with five brown vittae ; pleura sparsely cinereous above, 

 with brown stripe across mesopleura. Scutellum brown. Abdomen 

 with segments i to 3 sparsely brown pruinose ; apices of 2 to 3 mar- 

 gined with silver, broadly interrupted medianly ; segments 4 to 5 pol- 

 ished, former with four, latter with three, submarginal silvery dots ; 

 all segments with lateral margins narrowly silvery. Femora black, 

 apices yellow ; fore tibiae entirely, apices and bases of middle and hind 

 tibiae and median ring on latter yellow ; apices of tarsi black. 



Front hardly twice as broad as long ; orbits nearly parallel. Face 

 abruptly narrowed to about width of third antennal joint, with orbits 

 parallel for short distance then broadening into cheeks ; but little de- 

 pressed below antennae and in profile obliquely protruding below, the 

 prominence shining with convex margin ; parafacial grooves above close 

 and parallel, separated by an equally narrow yellow stripe which broad- 

 ens below into the protruding median area; bristles hair-like. Cheeks 

 hardly as broad as third antennal joint. Latter subconical with upper 

 margin straight; arista hardly half as long as third, with 9-10 hairs. 



Dorso-central and intra-alar setulae discernible. Chaetotaxy as in 

 P. calverti. Scutellum broad, flat, apex truncate. Venation as in Fig- 

 ure i. Length 1.5 mm.

 bits white ; facial groove brown ; median area ochreous to white below ;
