follows : Palpi hardly thickened at bai*e, pale brownish yellow ; third 

 autennal joint considerably excised, with a very distinct angle, seg- 

 ments of annulate ])ortion not distinct. Thorax with five narrow 

 gray vittte ; otherwise agrees well, but the eyes are nearly l)are, and 

 very indistinctly, if at all, pubescent. 



9. Therioplectes coinaNtes Will. 



Custer County, Colorado (T. D. A. Cockerell). Three females I 

 refer to this species on account of the reddish first, second auvl base 

 of the third antenna! joints, and the absence of any cloud on furca- 

 tion of third vein. T. phenops O. S. differs only in the black 

 antennae. 



Placer and Santa Clara Counties, California (E. M. Ehrhorn). 

 Two females. Length 13 mm., I am inclined to refer to this species. 

 They differ as follows from Williston's descrijition : Face is white 

 with white pile, that on upper border near eyes narrowly blackish ; 

 palpi pale yellowish, or rather whitish, with sparse black hairs and 

 white pile ; basal joints of antennse pale reddish ; front is but slightly 

 convergent anteriorly ; first to fourth abdominal segments with an 

 oblique area of whitish hair on sides, all segments thinly bordered 

 behind with whitish hair, and abdomen with whitish hair on sides. 



10. Therioplectes zonalis Kiiby. 



Orono, Me. (Harvey) ; two females. Length 16.5 and 18 mm. 

 The smaller female has yellowish hair on cheeks, and the yellow bor- 

 ders of abdominal segments very nari'ow ; liut the light reddish ante- 

 alar tubercle, brownish palpi, and narrow front indicate zonalis. 

 The hair of abdomen, also, except on hind borders of segments, is 

 black. The other specimen is more normal, but the yellowish bor- 

 ders of the abdominal segments bear black hairs among the yellow, 

 becoming almost exclusively black on the last two or three segments. 



11. Atylotus baal n. sp. 



Leugtb 14 mm. — Frout moderately broad, black ; frontal callosity scjuare, shin- 

 ing, with a prolongation, above which is widened on terminal half or more. Face 

 blackish, cheeks with whitish hair. Antennse pale yellowish, with a brownish 

 tinge, annulate portion of third joint shining black; third antennal joint very 

 slightly excised above ; palpi whitish, with l)lack hairs ; pleurse and pectus black- 

 ish, with whitish hair. Thorax brown, with short yellowish hairs, scutellum 

 concoloi'ous. Abdomen pale yellowish brown, with a yellowish, more or less in- 

 terrupted median streak, some short whitish hair on middle of first segment and 

 on outer posterior mai'gins of other segments (perhaps also along median vitta, 

 but if so, rubbed off), rest of abdomen with short black hairs. Venter moi'e yel-
