DIPTERA. 285 



real E. modestus (Loew) I cannot say with certainty is of the same species. The face is 

 for the most part shining black, the oral margin yellow. The abdomen has the first 

 segment covered with white tomentum or hair ; the second segment with a broad band 

 of black tomentum in front, an equally broad fulvous one behind it, and the immediate 

 hind margin whitish ; the remaining segments are covered with fulvous tomentum, 

 except on the immediate hind margin, where it is whitish. 



APHCEBANTUS (p. 143). 



Aphoebantus conurus (p. 148). 



To the localities given, add : — Mexico, Hacienda de la Imagen, Tepetlapa, and 

 Chilpancingo in Guerrero {H. H. Smith). 



Seven specimens, including male and female. The males agree well with the types 

 in the Kansas University collection, save that the bristles on the hind margin of the 

 abdominal segments are for the most part white. The females accord in nearly every 

 detail with A. cervinus, Loew, from Texas ; the face, however, is prominent, not as 

 much so as in the species of Epacmus, but more so than most of those of Aphoebantus. 

 Coquillett, in his Tables of the North-American forms, has wrongly identified the last- 

 mentioned insect, which has the hind margin of the scutellum shining, as expressly 

 stated by Loew. 



If I have correctly identified A. cervinus, the genus Epacmus cannot be distinguished 

 from Aphoebantus by the structure of the face ; and as to the presence or absence of 

 pulvilli, I agree with Coquillett that it is a character of doubtful value. 



BOMBYLIUS (p. 150). 



3. Bombylius io, sp. n. (Tab. V. fig. 7, 6 .) 



2 . Black. Front and face clothed with golden-yellow pile, the vertex sometimes with a few black hairs. 

 Antennae longer than the distance from vertex to oral margin ; first two joints yellow, with yellow hair ; 

 third joint slender, broadest at the base, longer than the first two joints together, the style small. Proboscis 

 about as long as the thorax. Thorax and abdomen clothed with abundant, moderately long, bright 

 yellow hair, without admixture of darker hair ; some black hairs on the venter posteriorly. Legs light 

 yellow ; distal tarsal joints brown. Wings hyaline, yellowish at the base. 



<J. Like the female, except that there is no black hair on the venter; eyes broadly contiguous; the first two 

 joints of the antennae usually brownish or brown. Length 8-12 millim. 



Bab. Mexico, Dos Arroyos and Acaguizotla in Guerrero (H. H. Smith). 



Eight specimens. In one of them the femora are brownish, in others they are light 

 yellow. 



4. Bombylius clio, sp. n. 



Q Like B. io, but with the first two joints of the antennas black and clothed with black hair ; the hairs on 

 the face usually black ; the posterior part of the mesonotum and the abdomen with scattered, long, black 

 hairs ; the wings more infuscated at the base.
