Miss G. Ricardo on the Asilide. 227 
Antenne with the third joint as long as first one. Thorax 
covered with ashy-grey and brown tomentum, stripes not 
visible. 4bdomen with the black spots and narrow yellowish- 
haired segmentations, pubescence elsewhere chiefly black. 
Genitalia with very long upper forceps joining at end, 
under pair as long, curved up to them, the last segment of 
abdomen below somewhat produced. V.d. Wulp says the 
Ovipositor is short, and gives the length as 16-184} mm. 
This male measures about 154 mm. 
In the types of P. calorificus the hairs of palpi are black 
and yellow. Ovipositor of female short, black. 
The male of P. calorificus is smaller than that of P. con- 
color, but the genitalia in both are identical. 
In vy. d. Wulp’s figure the lower forceps are not so long, 
and do not reach up to the upper pair as they do in both 
these males. In spite of this, I believe they are the same 
species. 
Legs reddish, the fore and middle femora with a short 
black streak above, the hind pair wholly reddish; tarsi 
black.
