52. EXETASTES GEMINUS. new species 



This species is extremely closely aUied to anthracinus, perhaps only 

 a southern race of that species, but the nine specimens at hand differ 

 constantly by the key characters, though in practically every other 

 respect they are like anthracinus. 



Type locality. — Swannanoa, N. C. 



Type.— V.S.N. M. no. 51828.

53. EXETASTES PERSIMILIS, new species 



Plate 19, Figure 73 



Like geminus this is perhaps only a geographical race of anthracinus, 

 but the temples are distinctly more strongly convex and less strongly 

 receding, forming with the longitudinal axis an angle of distinctly less 

 than 45°; the ocelli are larger, in diameter much more than half posto- 

 cellar line; the malar space is fully three-fourths basal width of man- 

 dible; the punctation of the thorax is distinctly finer and denser; and 

 the front and middle legs are reddish piceous rather than black, with 

 the front legs in female paler reddish in front rather than yellowish, 

 though distinctly pale in male. 



The male differs from the female as does the male of anthracinus 

 from its female. 



Type locality. — Boulder, Colo. 



r?/pe.— U.S.N.M. no. 51829.
