the Asilidiu of Aut.ltulusict. 449 



Asilus exilis, ^lacquart. 



Type (a male) seen by me in Paris Museum, 12. 4. 11. 



A very small species, measuring 12 mm. 



Face narrow, with a distinct tubercle. Moustache com- 

 posed of many white and black hairs. Aniennce black, the 

 first two joints with black hairs, the third conical, with a 

 long arista. Thorax bhick, marked with grey tomcntose 

 stripes and with black bristles at sides and posteriorly ; 

 Seidell um with white bristles. Abdomen blackish, with lighter 

 segmentations and pale pubescence. Leys black, tibiae and 

 coxiie reddish, femora with white hairs below. Genitalia 

 club-shaped, with fine filaments below\ 



Asilus villicatus, Wlk., might possibly be identical. 



Asilus laticornis, Macquart. 



Type (a female) in very bad preservation, with theantenn;e 

 destroyed, seen by me in Paris Museum, 12. 4. 11. 



It is evidently a small species of the genus Asilus in sensu 

 lato with the neuration of wings normal, the fourth posterior 

 cell closed, the small transverse vein situated just beyond 

 the middle of discal cell. Abdomen Avith a short conical 

 ovipositor, the segmentations greyish tomentose. Legs 

 black, tibiffi apparently testaceous. 



In Macquart^s figure of the antenncs the third joint is 

 short, about as long as the first two together, and broad, 

 with a terminal arista shorter than the joint itself. 



Asilus varifemoratus, Macquart. 



Type seen in Paris Museum, 12. 4. II ; part of the abdo- 

 men gone. 



A small species. Moustache white, antennce black. Abdo- 

 men h\a.ck, the pubescence white; segmentations appear to 

 be reddish. Legs black, femora witli white hairs below ; 

 tibiae yellow-red, black at apices ; tarsi yellow-red, black at 

 apices, bristles largely white. Wings clear, grey at apex, the 

 fourth posterior cell closed. 



Of the Asilus species of Walker from other parts of the 

 Australasian Region, Asilus areolaris ^ ? and areolatus (^ , 

 from Celebes, are species of Pantponerus. Asilus delerminatus 

 and introducens are nearly allied to Asilus discutiens, Wlk., 

 having tufts of bright-coloured or white hairs on basal seg- 

 ments, but the ovipositor in females seems entirely different.
