7(a). Anthrax hirsuta, sp. n. 



Black; abdomen clothed thickly with yellow pile, obscuring or concealing the sparse tomentum of the same 

 colour. Wings hyaline, with the base and two cross-bands brown, the proximal one extending across the 

 wing to the tip of the anal cell, with two hyaline spots, one just back of the second vein, the other m 

 the proximal end of the discal cell ; the second cross-band reaches from the tip of the first vein over the 

 posterior cross-vein ; a small brown spot at the tip of the anterior furcation of the third vein ; first 

 posterior cell narrowed in the margin. Tip of the abdomen with black pile on the sides, and a tuft of 

 white pile in the middle. Mesonotum with yellow pile, intermixed with black, the disk apparently bare ; 

 tomentum yellow. Pleura? with more whitish pile. Legs yellow, the femora in part, and the tip of the 

 tarsi, blackish. Front tibias with spinules ; front tarsi small, without hair ; pulvilli wanting. Face 

 strongly conical. Third antennal joint short, conical, not one-half the length of the styliform prolongation. 

 Front rather narrow above, clothed with erect black pile and yellow tomentum. Cheeks reddish. Length 

 13 millim. 



Hab. Mexico, Acaguizotla in Guerrero (H. II. Smith). 

 One specimen. 



10 (a). Anthrax (Chrysanthrax) astarte. 



Anthrax astarte, Wiedern. Aussereur. zweifl. Ins. ii. p. 637 \ 



c? 2 . Abdomen with the ground-colour reddish at the sides ; tomentum dense ; on the sides, for nearly a third 

 of the width, fulvous ; in the middle black, from the base to the sixth segment, with a few scattered 

 yellow scales on the hind margin of the median segments ; hair nowhere long. Body elsewhere black, 

 the sides of the face and cheeks, only, yellowish. Slender portion of the third antennal joint about as 

 long as the conical part. Proboscis not protruding beyond the oral margin. Hair and tomentum every- 

 where fulvous, except the erect pile of the front, and the similar, though scattered, pile of the mesonotum, 

 which are black. The brown coloration of the wings has a yellowish tint in places, and about the 

 cross-veins on either side of the discal cell it is perceptibly darker ; it fills out the whole of the subcostal 

 cell and leaves the tip of the anal cell, and sometimes the outer posterior margin of the anal angle, hyaline ; 

 contact of discal and fourth posterior cells punctiform. Length 10-15 millim. 



Hab. Mexico, Dos Arroyos, Rincon, and Tierra Colorada in Guerrero, Teapa in 

 Tabasco (H. H. Smith). 



Seventeen specimens. The species is a typical Chrysanthrax, as denned by Osten 

 Sacken. It was placed by him in the list of unidentified species (antea, p. 140). 



14(a). Anthrax leucothoa. 



Anthrax leucothoa, Wiedern. Aussereur. zweifl. Ins. ii. p. 638 \ 



Hab. Mexico \ Acaguizotla, Chilpancingo, and Tepetlapa in Guerrero (H. H Smith). 



The five specimens which I identify as this species differ from A. diana in having the 

 legs black, with the hind tibia? only somewhat reddish, the hair of the pectus and front 

 coxa? black (not yellowish), the outer part of the wings less purely hyaline, and the 

 clouds on the outer cross-veins smaller, that on the base of the second posterior cell 

 being only feebly indicated ; moreover, all of them have (male and female) a stump of 

 a vein at the furcation of the third vein. A. leucothoa was placed by Osten Sacken in 

 the list of unidentified species {antea, p. 140).
