last spots are sometimes very faintly distinct, bvit there are no other 

 spots besides the six above described. 



BOMBYLIUS PENTASPILUS, sp. nov., (^ . 



Distinct from the other species on account of the yellow peristomial 

 comb and of the yellow spines on the legs. Winces blackened along 

 the fore border. 



Type c^, from Dnnbrody, Uitenhage (Cape), May, 1900 (J. A. 

 O'Neil). Length of body 11-13 mm. Head black, with whitish 

 hairs, those of the hind border long ; bristles black, but those of the 

 peristomial comb yellow, witli a few black ones intermingled ; antennae 

 black, with tlie third joint linear ; proboscis black, 4-5 mm. long. 

 Thorax and scutellum black, with dense whitish sericeous hairs ; 

 bristles yellow, but black on the notopleural line and before the root 

 of the wings ; those on the hind border of the scutellum are yellow. 

 Squamae dark brown, white-fringed ; haltères blackish. Abdomen 

 clothed with hairs like those of the thorax and with yellow bristles ; 

 there are black hairs below at end and on the sides ; the puljescence 

 at the apex is tuft-like. Legs black, with yellow spines, even those of 

 the hind femoi'a ; claws black, long. Wings with Idack basal comb 

 and with white-scaled costa ; first posterior cell with a long stalk ; 

 discoidal cell broad at end, the discal cross-vein set a little after its 

 middle. Wings w'ith the base and the fore border broadly iufuscate 

 to the end of the marginal cell, wdiicli has no hyaline spots at apex ; 

 the three greater brown spots at the end of basal cell and at the base 

 of the second submarginal cell are in contact with the dark fore border, 

 and they are therefore much less striking ; the two smaller spots are 

 at the end of the first and at the base of the third posterior cells. 



BoiMBYLIUS OBESUS, Sp. nOV., c( , $ . 



Of this species of greater size I have two specimens in my own 

 collection, collected by Dr. Brauns at Willowmore (Cape) in August, 

 1906. It is distinguished from the preceding by the hyaline marginal 

 cell and by the infuscated cross-vein at end of the discoidal cell. A 

 female specimen from Isipingo (Natal) in the collection has a black 

 peristomial comb. Head black ; frons of male broader than usual, 

 and that of the female tAvice as broad ; hairs long, greyish or white ; 

 bristles black, but those on the occiput yellowish, chiefly in the 

 female ; bristles of the peristomial comb yellow above and black 

 beneath. Antennae black, with long black hairs at base ; third joint 

 linear, styliform ; proboscis black, 5'5-6 mm. long. Thorax and
