Miss G. Ricavdo on the Asilidae. 221} 



The species is curiously like the African species P.fasci- 

 atus, F., but the genitalia are ditt'ereiit, 



A black species distinguished by the wholly black legs 

 and by the black abdomen with bushy white hairs on the 

 first two segments of abdomen. Moustache yellow below, 

 black al)ove. Thorax black with no signs of stripes. Scu- 

 tellum with black bristles and hairs. Genitalia of male 

 large, the \ipper forceps with a blunt tooth near the base, 

 then becoming concave on their inner edge, and ending in 

 a blunt point, under pair short small, all hairs are bhick 

 and numerous. Leys with chiefly black pubescence, some 

 yellowish pubescence on the femora. 



Length, S 25-26, ? 23 mm. 



V. d. Wulp gives the length as 19-22 mm.

A male from Sarawak, Borneo, another from Mt. Dulit, 

 Philippines {Everett Coll.), 1901, 247. 



A female from Pasir Ganting, West Coast, Sumatra, 

 lat. 2° S., June 1914. 



A female from Irisan, Benquet Province, Luzon. 



V. d. Wulp described a female froui Java, de Meijore a 

 m:de and female from Padang, W. of Sumatra. Wulp 

 describes the hairs on abdomen as ochre-yellow. De Meijere 

 states tiiey are so in the female, but in his male nearly 

 white ; he also gives the colour of the legs in both sex(;s as 

 largely reddish, not pitchy brown as v. d. Wulp says, the 

 femora being reddish below. 



These specimens in the Brit. Mus. Coll. answer very 

 fairly to the description, with the additional remarks by 

 de Meijere, so that it seems safe to conclude it is rather a 

 variable species with a wide distribution. 



The haiis on abdomen in both sexes are whitish, tinged 

 yellow in the female. Legs dull reddish, femora darker 

 above, tarsi all black, and apices of tibiic the same. Palpi 

 in male with chiefly black hairs, in female some yellow 

 hairs are intermixed. Moustache in male black and yellow, 

 in female black sometimes with a few yellow bristles, in 

 male the yellow bristles or hairs arc a little more numerous. 



A black species distinguished i)y the wliite hairs on the 

 first three segments of the abdomen, by the partly reddish
