P. FILIPALPIS, End. 



The characters of this species, according to Rondani, are very variable, so I 

 shall describe them as they occur in the single example which I possess. The point ["2111 

 which at once distinguishes this species from all the others is the diminutive state *"&•> ^"'''- 

 of the palpi, which are pale yellow in colour, and very short and small ; the fore- 

 head is slightly prominent, the frontal stripe piceous, and rather narrower than the 

 sides of the frontalia, which are grey with a rufous tinge ; fronto-orbital bristles 

 extending to below the root of the arista ; cheeks white and bare ; antennse with 

 third joint thick, and fully six times the length of the second ; arista with basal 

 third thickened; facialia armed with strong cilite for two-thirds of the way up; 

 thorax cinereous, with four even black stripes ; scutellum grey ; abdomen cinereous, 

 with posterior margins of segments black ; setse on both disc and margins ; wings 

 with apical cross vein straight, and ending near apex, fourth vein bent in a blunt 

 angle, outer cross vein a little sinuous, and placed rather nearer to the angle of the 

 fourth than to the little cross vein ; legs black ; length of specimen about 6 mm. 

 Very rare.

Chetogenci assimilis, Rnd. 



Forehead prominent, frontal stripe black, and wider than sides of frontalia, 

 which are slate coloured ; cheeks white, with grey reflections, and ciliated with a few 

 fine hairs ; antennse with first joint partly rufous, the second and third grey, the 

 latter about four times the length of the former ; arista long, with basal third 

 thickened, and rest extremely slender ; palpi yellow, grey and thin at the base, and 

 sub-clavate at the end ; facialia ciliated for about two-thirds of the way up ; thorax 

 covered with dark grey pubescence, and marked with four black stripes of about equal 

 widths, which become indistinct on the hinder portion ; outer doro-central bristles, 

 three in front and three behind the suture ; scutellum dark grey, sometimes a little 

 rufous at the tip ; abdomen cylindrico-conical, with black and white tessellations, 

 and armed with both diseal and marginal seta; j anal segments of male incurved, and 

 sometimes partly rufous ; wings with apical cross veins deeply curved ; legs black, 

 hind tarsi ciliated beneath with yellow hairs. Not uncommon. This species varies 

 very much in size.
