ANTHRAX. 125 



scutellum ; there are characters enough, nevertheless, to render the species recognizable. 

 The description of A. leucothoa, Wiedem. Aussereur. zweifl. Ins. ii. p. 638 (Mexico), 

 agrees quite well with this species, except " the three last segments of the abdomen 

 densely covered with a silvery-white tomentum." I do not see any trace of such a 

 tomentum on the four specimens of both sexes before me. The statement about the 

 third joint of the antenna? being somewhat globular, " etwas kugelig," likewise does not 

 agree with Prof. Bellardi's specimens. 



15. Anthrax cuniculus, sp. n., <? $ . (Tab. II. fig. 16.) 



Ground-colour of the body black ; the hair on the front part of the thorax very pale yellowish ; on each side, 

 above the wings, a stripe-like patch of white hairs not quite reaching the humeri ; an appressed white 

 tomentum of moderate density on the scutellum and on the abdomen ; the latter with only the fourth 

 segment darker (which, so far as I can see in two tolerably preserved specimens, is not due to abrasion) ; 

 the sides of the abdomen fringed with white hair ; a tuft of black hair on the fourth segment ; rufous 

 macrochaetae on the post-alar callosities ; pleurae and venter with white hair. Face conically projecting ; 

 face and front rather dark, with the usual rather dense covering of orichalceous appressed tomentum and 

 black erect hairs ; proboscis not protruding ; antennae — basal joints somewhat reddish on the underside ; the 

 third joint black, short but broad, conical, with a style not longer than the cone. The reddish or brownish 

 ground-colour of the legs hidden under a covering of whitish or yellowish scales ; tarsi dark brown. 

 Antero-proximal half of the wings of a but moderately intense brown, which reaches but very little 

 beyond the large and small cross-veins ; the encroachment of the brown on the first submarginal and 

 third posterior cells is also very trifling, but in the discal cell it occupies about one third ; the brown 

 nearly fades away before the end of the anal and also from the whole of the axillary cell, which is more 

 grey than brown ; the usual subhyaline spot before the proximal end of the discal cell is large and distinct, 

 but there are no other subhyaline spots within the brown ; the tip of the subcostal cell is hyaline ; the 

 contact of the fourth posterior cell with the discal is short. 



Length 7-8-5 millim. 



Hab. Mexico, Northern Sonora (Morrison). 



Four specimens. 



The description has been principally drawn from a well-preserved male. 



16. Anthrax consul, sp. n., $ . 



Thorax with pale fulvous hair in front, and black hair on the pectus (dorsum and scutellum abraded) ; long 

 black macrochaetsa on the post-alar callosities and on the scutellum ; a fringe of yellowish-white hairs 

 on the sides of the thorax behind the wings, as well as on the sides of segments 1 and 2 of the abdomen ; 

 the sides of segments 3-7 beset with tufts of black hair; the surface of the abdomen (very much 

 abraded) seems to have had a pale yellow tomentum on segments 2-4 anteriorly, and a covering of some 

 black scaly hairs on the same segments posteriorly ; segments 6 and 7 are covered with a white, almost 

 silvery, tomentum, their posterior margins being beset with black hair; venter black. Legs black. 

 Halteres with a pale brownish knob (?) Face conically projecting, black, with the usual orichalceous 

 tomentum, and black, erect hairs ; antennae black, the first joint rather long, the third an elongated cone 

 gradually merging into a style ; occiput clothed with pale golden-yellow tomentum and pile ; proboscia 

 not projecting ; the oral margin above it beset with short, black bristles. Antero-proximal part of the 

 wings of a not very dark brown ; axillary cell hyaline, except a little brown in its proximal portion. The 

 brown in the anal cell reaches a little beyond the great cross-vein, encroaching very little upon the fourth 

 and third posterior cells, and filling a little less than the proximal half of the discal cell ; it encroaches on 

 the first posterior cell a little more than the length of the anterior cross-vein, and then runs obliquely
