11, p. 93), I referred to this species, with some doubt, a single 9 speci- 

 men from Canada ; since then I have received, through the kindness 

 of Mr. WilUam Saunders and Mr. T. B. Ashton, a fine series ( 9 , $ 

 and S ) of the true horealis of Kirby. The characters of this fine 

 species are as fijllows : — 



Female. — Head black, with the face and vertex clothed with pale 

 yellowish pubescence, slightly tawny on the vertex. Thorax above 

 densely clothed with bright tawny-yellow pubescence, with a broad 

 black band between the wings ; beneath entirely black. Wings fuseo- 

 hyaline. darkest along the apical margin. Legs black, tarsi pale with- 

 out, rufous within. Abdomen above with the four basal seamen ts 

 clothed with bright tawny-yellow pubescence, the two apical segments 

 black; beneath black. Length 8 — 9 lines. 



Worker. — Colored same as the female. Length 6 lines. 



Male. — Like the female and worker, except that the antennae are as 

 long as the thorax and setaceous, the sides of the thorax and the femora 

 beneath are sometimes mixed with yellowish, the three apical segments 

 of the abdomen above are more or less mixed with yellow and the last 

 segment is tufted, the ventral segments are clothed with short pale yel- 

 lowish pubescence. Length 7 — 8 lines.

The males have much the appearance of some of the S varieties of 

 Apatliu.-i elatua Fabr., but they do not belong to that genus. 



The single 9 specimen which I supposed to be identical with this 

 species, difiers from the 9 above described by having the abdomen 

 above tawny-yellow, except the last segment which is black, and the 

 ventral segments are clothed with short pale pubescence. It may be 

 only a variety, and for the present it is probably best to consider it as 

 such. 



Genus APATHUS, Newm. 

 7. Apathus Ashtoni, n. sj). 



Female. — Head entirely black. Thorax clothed above with pale yel- 

 lowish, and beneath with black pubescence, on the disk above between 

 the wings there is a mixture of black hairs and the scutellum is some- 

 times altogether black. Wings fusco-hyaline, darker along the apical 

 margin. Legs black, with black hairs, tarsi within rufous, the apical
