This interesting form and type of the genus was taken at Mont- 

 pelier, Yt., June 26, 1906 by Prof. C. W. Johnson. 



Male. Length 4 mm. Antennae as long as the body, thickly long 

 haired, dark brown; 16 segments, the fifth with a stem one-half 

 longer than the subcylindric basal enlargement, which latter has a 



length twice its diameter, a subbasal 

 whorl of short, stout, slightly curved 

 setae, near the basal third a thick 

 whorl of closely set, long, strongly 

 curved setae arising from conspicuous 

 tubercles ; subapically there is a scat- 

 tering whorl of similar long setae; 

 terminal segment with the basal por- 

 tion slightly produced, the stem much 

 reduced, rudimentary. Palpi ; the first 

 segment short, stout, subquadrate, the 

 second fully twice the length of the 

 first, expanding distally, the third a 

 little stouter, about as long as the sec- 

 ond, the fourth shorter and more 

 slender than the third, the fifth nearly 

 twice the length of the fourth, all 

 sparsely clothed with coarse setae; 

 face fuscous yellowish, eyes rather 

 large, black. Mesonotum dark red-
