towards the end of the auxiliary vein. The contact of the fourth posterior cell with the discal is shorter 

 than the anterior cross-vein. 

 Length 10-11 millim. 



Hab. Guatemala, San Geronimo [Champion). 



A single female. In this insect the front tibiae and tarsi are formed like those of 

 A. cuniculus.

Hab. United States, Illinois 1 , Detroit, Michigan (0. SacJceri). — Mexico, Oaxaca 

 (Sumichrast). 



" Black, opaque, with luteo-fuscous hairs and tomentum, the thoracic dorsum mostly 

 beset with black hair ; the hind margins of the last abdominal segments beset with 

 some black hairs ; face drawn out in a cone ; the third antennal joint conical ; legs of a 

 saturate luteo-testaceous ; half of the wings black, the limit of the black colour sub- 

 equal and very oblique. 



" Allied to A. fulvo-hirta, Wiedem. Black, opaque, the scutellum of the same colour. 

 Head black, the face conical, of a saturate luteous colour, except a stripe in the middle ; 

 hair of the front and of the face black, the tomentum luteo-subfuscous. Proboscis not 

 projecting. Antennae black; first joint dark luteous on the underside, with black 

 pile; third joint conical. Hairs of the thorax fusco-luteous, those on the thoracic 

 dorsum nearly all black ; a good many black hairs on the pleurae ; tomentum of the 

 thoracic dorsum fusco-luteous. The hairs on the abdomen are fusco-luteous, except 

 a few slender black ones on the posterior angles of each and also along the hind margins 

 of the last segments ; the tomentum on the abdomen of the same colour as the hairs, 

 whitish on the disc of the last segment. Venter black, the pile and a sparse tomentum 

 luteous. Legs luteo-testaceous, the tarsi black towards the tip. Wings hyaline, the 

 basal half black ; the limit of the black colour subequal, very oblique, almost straight, 

 very slightly concave anteriorly, more distinctly convex posteriorly : it reaches from the 

 tip of the auxiliary vein to the last third of the axillary angle." — Loew, I. c. 



I have before me a specimen from Detroit, Mich., which I have compared with the 

 type in Cambridge, Mass. The cone of the third joint of the antennae is rather short, 

 but has a linear prolongation which exceeds its own length. There are distinct tufts 

 of whitish-yellow pile on each side of the thoracic dorsum above the roots of the wings. 

 I do not perceive the whitish hair on the last segment which Loew mentions. The 

 brown of the wings is rather even in colour, and has no subpellucid spots on the 

 bifurcations and cross-veins, except the usual spot near the proximal end of the 

 discal cell. The surface of the abdomen of my specimen is abraded, and Loew's type, 

 so far as I remember it, is in the same condition. My specimen is 11-12 millim. long.
