The Subfamily Eccoptogasterin^. 



key to the genera, 



This subfamily is represented in our territory by the single genus Eccopto- 

 gaster Herbst. 

 A The fore tibiae with the outer apical angle produced into a curved spine, 

 the inner apical angle acute but not produced beyond the tarsal inser- 

 tion (PL 9, figs. 16, 17). 

 B Venter of the abdomen ascending abruptly behind; the antennal scape 

 very short (PI. 17, fig. 10). Eccoptogaster Herbst. Page 50. 



BB Venter of the abdomen normal, nearly horizontal. Loganius Chap. 

 AA The fore tibise with the outer apical angle produced into a bifid process, 

 with a tooth at the inner apical angle extending beyond the tarsal 

 insertion, and one or more serrations on the outer margin. 

 B The pronotum transversely rugose in front, the outer margin of the 

 fore tibiae strongly serrate. Erineophilus Hopk. 



BB The pronotum not rugose in front. 



C The pronotum with the side margin well defined. 



Bothrosternus Eichh. 

 CC The pronotum without a definite side margin. 



D The sutures of the club curved; rostrum narrower than the front; 



body oval. Pagiocerus Eichh. 



DD The sutures of the club straight; rostrum scarcely narrower than 



the front; body oblong. Cnesinus Lee. 



The Subfamily Hylesinin^. 



KEY TO the genera. 



A The antennal funicle of two or three segments; the foretarsal segments 

 cylindric; very small species (PI. 10, fig. 9). 

 B The antennal funicle of two segments, the club with sutures only at 

 the extreme apex. Crypturgus Er. Page 54. 



BB The antennal funicle of three segments, the club segmented. 



Dolurgus Eichh. Page 55 . 

 AA The antennal funicle of more than three segments; species of moderate or 

 large size, 



B The third foretarsal segment cylindric, not widened; forecoxae almost 

 contiguous, (PI. 21, fig. 1). 



C The eyes divided (PI. 9, fig. 36); the antennal club unsegmented, 



the scape much longer than the funicle (PI. 10, fig. 27) ; the base 



of the elytra not much elevated and feebly crenulate (PI. 21, 



fig. 1). Polygraphus Er. Page 55. 



CC The eyes not divided; the club segmented, the scape stout, but 



little longer than the funicle; the base of the elytra elevated and 



strongly serrate. 



D The eyes rather deeply, narrowly emarginate; the elytral declivity 



with carinate interspaces; the scape slightly longer than the 



funicle (PL 10, fig. 20). Carphoborus Eichh. Page 56. 



DD The eyes feebly sinuate in front, hardly emarginate; the elytral 



declivity evenly convex; the scape shorter than the funicle. 



E The anterior coxae in contact with the head beneath, the 



prosternum before them obsolete; the tibiae margined with 



short stout teeth. Cal. Renocis Csy.
