ANTHKAX. 127 



I have several specimens from Dallas, Texas (Boll), which perhaps belong to the 

 same species, although they are only 8-9 millim. long. The well-preserved abdomen 

 is covered with a dense, appressed, yellowish tomentum, but the first segment, the 

 posterior half of the second and third segments, and nearly the whole of the fourth 

 (except the anterior angles) are black. 



In Professor Bellardi's collection in Turin there is a very much abraded specimen 

 from Oaxaca (Sumichrast), which I take for A. palliata. 



N.B. — The three preceding species (A. cuniculus, A. consul, and A. palliata) form a 

 ^^^ natural group, having a conically protruding face, the same structure of the antennae 

 (a cone with a long linear prolongation), the same coloration of the wings (brown 

 antero-proximal half, leaving a considerable part of the axillary cell hyaline ; no sub- 

 hyaline spots or cross-veins &c), and same structure of front legs (tibiae with spinules ; 

 tarsi with distinct joints).

Anthrax castanea, Jaennicke, Neue exot. Dipt. 30, t. 2. f. 15. 



Eab. Mexico (Jaenniclce) ; Guatemala, San Geronimo (Champion). Five specimens. 



The original description having been made from imperfect specimens, I give a more 

 complete one : — 



Face projecting in a pointed cone, brown, reddish along the sides, the front black ; both 

 are clothed with a fulvous tomentum ; short, black, erect hairs on the front ; first joint 

 of the antennae reddish, the third black, conical, and with a long styliform prolongation ; 

 proboscis not projecting beyond the oral margin (or projecting very little). Thorax with 

 long fulvous pile, and a shorter, fulvous tomentum, between which two greyish stripes, 

 interrupted some distance before the scutellum, are visible on the dark ground. Abdomen 

 with long fulvous pile, and a shorter, fulvous tomentum ; the two last segments, in the 

 middle, are beset with white hairs, forming a conspicuous white spot. (I believe that 

 both sexes have this spot, because one of the specimens, which I recognize as a female, 

 shows some white hairs at the end of the rather rubbed off abdomen.) Legs reddish, 

 the tarsi darker. The wings (very well figured by Jaennicke) have a brown base, 

 two cross-bands, and some smaller brown spots at the ends. Length 10-14 millim. 



N.B. — The front tibiae are beset with spinules ; the tarsi have distinct joints, com- 

 paratively large ungues, and no pubescence on the upperside. The interval between 

 both eyes, in both sexes, is comparatively broad. 



19. Anthrax rex, sp. n., <$ $ . (Tab. II. fig. 17.) 



Ground-colour of the body black (sometimes reddish at the tip of the abdomen); face rounded, but little 

 projecting ; proboscis long, the portion reaching beyond the oral margin not quite so long as the head j 

 face and front black, beset with black, erect pile, and a shorter, orichalceous tomentum. Antennae black ; 

 first joint very short, slightly marked with red ; third joint short, onion-shaped, with a slender style,, 

 beginning abruptly, and almost twice as long as the rest of the antenna, and a microscopic, bristle-like
