240 SUPPLEMENT 1 . 



joints yellowish; hind tarsi light yellow, with the two distal joints blackish. "Wings hyaline ; narrow 

 and elongate, not expanded distally as in Bhaphiocera ; neuration of the /Storgw-type ; the furcation of 

 the second vein takes place nearly opposite the distal end of the discal cell. Length 10 millim. 



Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 



One specimen. Notwithstanding the presence of but seven annuli in the third 

 antennal joint, I place this species under Campeprosopa, as the characters seem other- 

 wise to agree exceedingly well. Possibly Analcocerus should be united with it, yet 

 the frontal protuberance and the shape of the wings may be sufficient, apart from the 

 lesser number of antennal annuli, to distinguish the two. 



HERMETIA (p. 27). 



Hermetia aurata (p. 28). 



To the localities given, add : — Mexico, Amula and Venta de Zopilote in Guerrero 

 (H. H. Smith), San Bias in Jalisco (Schumann). 



Osten Sacken (antea, p. 28) has referred H. chrysopila, Loew, to this species as a 

 synonym, but I do not feel sure that he is right. A specimen of what I believe to be 

 H. chrysopila, from New Mexico, in the collection of the University of Kansas, differs 

 as follows from the Mexican insects, which I take to be the true H. aurata of Bellardi : 

 Front more yellow, style of antennae relatively shorter, golden pile of thorax and 

 abdomen more abundant, humeri yellow, scutellum with a broad yellow margin. 

 Bellardi makes no mention of the yellow border to the scutellum, and in the five 

 specimens before me the scutellum shows no trace of that colour. 



Hermetia illucens (p. 32). 



Hermetia nigrifacies, Bigot, Ann. Soc. Ent. Fr. 1879, p. 200. 



Specimens of this species in the Mexican collection before me agree well with the 

 description of II. nigrifacies, Bigot, an insect not identified by Osten Sacken in the 

 earlier part of this work (antea, p. 42). Bigot's name must be sunk as a synonym 

 of H. illucens (Linn.).
