DIPTERA. 281 



Anthrax palliata (p. 126). 



To the localities given, add : — Mexico, Tepetlapa in Guerrero (H. II. Smith). 



Two specimens, the specific identity of which I do- not feel quite sure: they are 

 not more than 8 or 9 millimetres in length ; the face is wholly reddish-yellow ; and 

 the antennas are reddish, with the slender termination of the cone not longer than the 

 cone itself. The abdomen is wholly covered with light yellowish pile and tomentum 

 (I can only distinguish a few black hairs posteriorly). The tarsi are brownish. The 

 brown coloration of the wings is of a light shade. 



Anthrax lepidota? (p. 130). 



A female Anthrax from Venta de Zopilote, Mexico (//. II. Smith), seems to agree 

 with A. lepidota, O. S., in all its characters, except as regards the structure of the face, 

 if I interpret the description aright: I should call it conical; the borders meet in 

 nearly a rectangle. The anal cell is about half filled out with brown colour, and there 

 are no scales on the hind tibiae. 



Two other, abraded specimens, from Hacienda de la Imagen and Acapulco respec- 

 tively (II. II. Smith), have a hyaline spot in the outer part of the second basal cell. All 

 three examples are somewhat smaller than those described by Osten Sacken. 



26 (a). Anthrax orbitalis, sp. n. (Tab. V. fig. 4, j .) 



<S . Wings deep brown and hyaline ; the brown coloration is of a uniform tint (without darker or lighter 

 markings), its border extending from the tip of the first vein, with a shallow concavity, sometimes relieved 

 by a short convexity in its middle, to very near the end of the anal cell ; first posterior cell broadly open ; 

 a stump of a vein usually present on the furcation of the third vein. Body black throughout, the 

 immediate oral margin only yellowish. Head nearly spherical, the face not prominent in profile, the 

 proboscis short and retracted. Front clothed with black, its lower part, the face, and the posterior orbits 

 with dense silvery tomentum. Bulbous portion of the third antennal joint very short, almost reniform, 

 not more than one-third the length of the stylil'orm portion, the distal half of which is distinctly 

 attenuated. Mesonotum and scutellum deep velvety-black ; in well-preserved specimens there is some 

 yellow tomentum in front of the scutellum ; near the humeri and jus<t back of the halteres with golden 

 hair; pleurae with white hair. Abdomen clothed with deep black tomentum and hair; on either side of 

 the first segment with a conspicuous tuft of white hair; on each side of the fifth, sixth, and seventh 

 segments thickly white- or light yellowish-pilose. Front tibiae with minute spinules; pulvilli wanting ; 

 femora with white tomentum. Length 10 millim. 



Hab. Mexico, Chilpancingo, Rincon, Rio Papagaio, and Amula in Guerrero, Teapa 

 in Tabasco (H. II. Smith), Santiago Iscuintla and San Bias in Jalisco (Schumann). 



This species belongs in the subgenus Anthrax of Osten Sacken, and is nearly allied 

 to the following, A. curta, Loew. The anterior branch of the third vein is not 

 bisinuous. 



26 (b). Anthrax curta. 



Anthrax curta, Loew, Centur. viii. no. 35 '.
