HENRY J. FRANKLIN. 465 



Legs. — Dark. The hind metatarsi as already described for the 

 group, their posterior distal terminal projections exceptionally long 

 and acute. 



Male. Head. — Face with a strong touch of brownish-yellow hairs 

 both between and above the bases of the antennae ; occiput with a 

 triangular patch of yellow pile; otherwise dark. Malar space between 

 one-fourth and one- fifth as long as the eye. Clypeus covered with 

 black pile. Fifth antennal segment distinctly longer than the third ; 

 the third longer than the fourth. 



Thorax. — Anterior part of the dorsum covered with yellow pile back 

 to the tegulse ; the remainder of the dorsum dark except for a rather 

 faint sprinkling of yellow hairs on the sides of the scutellum. Each 

 mesopleuron with a strong sprinkling of yellow pile on its front half 

 reaching well down toward the bases of the legs, the remaining por- 

 tion being dark. Metapleura and median segment dark. 



Abdomen. — Dorsum : segments one and two dark ; segment three 

 mostly dark, but with yellow pile on its posterior corners and also a 

 little of the same color on its hind margin ; segment four mostly yel- 

 low, but with a strong admixture of black hairs on the very middle ; 

 segment five mostly dark, but with yellow pile on the extreme sides ; 

 segments six and seven dark. Venter dark. 



Wings. — Of about the same shade as those of the female. 



Legs. — All dark, except the tarsi. 



Difnensions. — Length: female, 15 mm.; male, 15 mm. Spread of 

 wings: female, 29 mm. ; male, 28 mm. 



It is quite possibe that these two specimens, coming from 

 such widely separated localities, do not belong to the same 

 species, but they are so much alike in general appearance 

 that it is my belief that they belong together, and I have 

 thought it better, under the circumstances, to describe them 

 as female and male of the same species than to describe 

 them as two separate new species. 



THE ASHTONI GROUP. 



Cha,racters of the Group. 



Female. — Occiput with at most only a sprinkling of yellow 



hairs. Malar space medium. Hind metatarsi very broad, 



about two and one-half times as long as their greatest width. 



Lateral elevations of hypopygium very prominent. 



Male. — Flagellum of antenna about three times as long as 

 the scape ; the third and fifth antennal segments subequal in 

 length. Clasper of genitalia (figs. 91, 92, 96, 99) with
