scutellum black, clothed with long and dense yellowish-grey hairs, 

 which, seen from the front, are shining white ; on the back there are 

 three less distinct, dark, longitudinal stripes, more developed in the 

 female ; all the bristles are yellow, but along the notopleural line 

 there are a few black ones. Squamae brown, white fringed, with 

 yellow bristles. Abdomen clothed with hairs like those of the thorax ; 

 on the sides and behind there are some small tufts of black hairs, not 

 visible from above ; all the bristles are yellow, and only a little longer 

 than the hairs ; venter with long yellowish hairs. Legs white scaled, 

 the tarsi and femora black, the tibiae dark yellowish ; all the spines 

 are long and yellow, even the 8-9 of the underside of the hind femora ; 

 claws black, those of the male twice as broad as those of the female. 

 Wings with black basal comb, but under the base there are some 

 yellow bristles, and inwards there is a tuft of long white hairs ; costa 

 white scaled ; first posterior and discoidal cell rather short, the last 

 broadly obtuse outwardly ; discal cross-vein placed on the last third of 

 the discoidal cell. The wings are almost entirely greyish hyaline, the 

 costal cell and the base being only lightly yellowish-grey ; the brown 

 spots are small and less darkened, the greatest of all being, as usual, 

 placed at the end of the second basal ; first basal end at the base of 

 the second submarginal cells ; the others are at the end of the first 

 and at the base of the third postei'ior cells ; the cross-vein at end of 

 the discoidal cell is, besides, marginated with fuscous. 



BOMBYLIUS SPINIBAEBUS, Sp. nOV., . 



An entirely yellow-haired, very distinct species with red scutellum 

 and yellow alar comb, forming a connecting link between the pre-

Type cT > and an additional example of the same sex from Stellen-

Length of body 10-12 mm. Head black ; frous moderately broad ; 

 all the hairs are yellow ; those on the occipital border are short and 

 those of the lower side are white ; all the bristles are yellow, those on 

 the first joint of the antennae are long, and those of the peristomial 

 comb are whitish. Antennae black, with the third joint linear, but 

 rather thick at base ; proboscis black, 4-5 mm. long. Thorax black, 

 densely clothed with rather short, entirely yellow hairs, which are 

 white and shining in certain lights ; the bristles are yellow, but less 

 developed than in the foregoing species, only those before the root of 

 the wings being strong. Scutellum entirely red above, with only the
