14 (b). Anthrax diana, sp. n. 



2 . Third antennal joint conical, the styliform portion longer than the bulbous portion. Face conical ; 

 proboscis -withdrawn. Black ; face and front with yellow appressed tomentum, the front with erect 

 black pile ; ground-colour of the oral margin yellow. Thorax with yellowish pile on the sides and in 

 front ; mesonotum with sparse yellowish tomentum and erect black pile. Abdomen with yellowish hair, 

 intermixed posteriorly with black ; tomentum of the same yellowish colour for the most part, the posterior 

 portion of the segments black-tomentose ; sixth and seventh segments densely covered with silvery-white 

 pile. Legs black or dark brown, with yellow tomentum ; the distal part of the anterior femora and all 

 the tibiae for the greater part yellow ; front tibiae with spinules. Wings brown on the antero-proximal 

 portion, hyaline distally ; the cross-veins on either side of the discal cell, within the brown portion, are 

 darker-coloured, and there is a conspicuous dark brown cloud on the furcation of the third vein, and one 

 equally large on the vein at the base of the second posterior cell ; the brown coloration of the furcature is 

 coalescent with the brown of the anterior part within the submarginal cell ; in the anal cell the brown 

 extends nearly as far as the base of the fourth posterior cell, and fills out the proximal portion of the 

 anal angle ; the dilated end of the marginal cell is wholly hyaline. Length 10-11 millim. 



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

 Four specimens. 



Anthrax consul (p. 125). 



To the locality given, add : — Mexico, Acaguizotla, Chilpancingo, Tepetlapa, and 

 Amula in Guerrero (II. II. Smith). 



Numerous specimens. The abdomen has a conspicuous, rather narrow, whitish or 

 yellowish band on the anterior part of the second, third, and fourth segments. The 

 sixth and seventh segments in the female are as described by Osten Sacken ; in the 

 male they are wholly silvery-white. There is a considerable amount of variation in 

 the degree of the encroachment of the brown colour in the axillary angle of the wings. 

 Certain examples from Brazil, in my collection, come very close to this species, and 

 Coquillett doubtfully identifies specimens from South Dakota with it. There are, 

 however, so many concurrent forms that direct comparison is needed to fully determine 

 examples from such remote localities. 



16 (a). Anthrax fulvohirta.

 Arroyos, Venta de Zopilote, Rio Papagaio, and Tierra Colorada in Guerrero (H. H. 



Smith). 



The pile and tomentum throughout is fulvous, not yellowish, and the tomentum of 

 the middle of the abdomen is largely intermixed with black or wholly black. The 

 species will be distinguished from A. astarte by the entirely brown anal and axillary 

 cells. The synonymy is given on Coquillett's authority 2 .
