278 SUPPLEMENT. 



fulvous tomentum and distinct black bristles along the margin. Mesonotum brownish-black, opaque, the 

 tomentum fulvous and black (the specimen is somewhat abraded) ; pleurae whitish, with white hair, which 

 is bushy and silvery above the front coxae. Head black, rounded in shape, the face scarcely visible in 

 profile, and clothed, like the front, with black and yellow pile. Antennae small ; third joint short, onion- 

 shaped, with a slender style nearly as long as the whole of the preceding portions of the antenna together. 

 Proboscis very short, with large, fleshy, pseudo-tracheate labella. Length 10 millim. 



Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 



A single example. The head has been glued on, and I am not quite sure that it 

 belongs to the remainder of the specimen. 



In not a few species of Anthrax, such as A. arethusa, &c, the fourth posterior cell 

 is divided by a cross-vein, and the vein is usually considered adventitious. In the 

 present insect this vein runs to the margin of the wing, and is quite as in those families 

 where the full complement of five posterior cells is present. This would indicate that 

 the stump, whenever present, is vestigial, and that those forms in which the fourth 

 posterior cell is divided have really five true posterior cells, a character lost in nearly 

 all the species of the family. 



Anthrax edititia (p. 119). 



Anthrax impiger, Coquillett, Trans. Am. Ent. Soc. xiv. p. 177 l . 



To the localities given, add : — United States, Arizona 1 . — Mexico, Venta de Zopilote 

 in Guerrero (E. H. Smith). 



I have no doubt whatever that the present insect is the real A. edititia of Say, whose 

 description agrees perfectly, and it is altogether probable that his types came from 

 Mexico. Coquillett's A. edititia (loc. cit. p. 175) is a different species, and the synonyms 

 quoted by him x therefore do not apply here. The Guerrero specimens agree well with 

 those of Osten Sacken, but in his figure the basal portion of the wings is paler. It is 

 evident that Coquillett must have overlooked this authors description and figure, as he 

 makes no mention of them in his later papers on Anthrax.

Anthrax paradoxa (p. 120). 



To the localities given, add : — Mexico, Acaguizotla in Guerrero (E. E. Smith). 



Two specimens appear to belong to this species. The face is not red, but black; the 

 first two joints of the antennae are black ; the abdomen is black, with yellow hair, and 

 some black hair on the sides, and with black tomentum. The legs are black. The 

 wings agree with Jaennicke's figure, save that there are no brown spots on the anterior 

 branch of the third vein, and the stumps are wanting. The bisinuosity of the second 

 vein is also wanting. Is Osten Sacken's insect from Texas of the same species ?
