E. StrigOSns Lee. — Form oi morio but much more shining, entirely black, 

 very sparsely pubescent. Elytra with strigse at least twice as distant as in 

 either of the preceding. Body beneath densely puuctulate. Legs and antennae 

 ferruginous. Length .10 inch; 2.5 mm. 



The sixth segment is feebly visible in the female. The posterior 

 tibiae have but one spur. 



One specimen, Pennsylvania. I have seen another specimen of 

 little greater size with the tip of the elytra reddish, from Nevada, 

 in the cabinet of Mr. Ulke, which with a larger number of speci- 

 mens may prove distinct. 



Tribe lll.—Euhrimi. 

 Head deflexed, front narrow contracted by the insertion of the 

 antennae and prolonged into a slight beak. Mandibles entirely con- 

 cealed. Maxillary palpi slender, elongated. Anterior coxae trans- 

 verse, without trochantin, separated by the prosternum and not more 

 prominent than it except in Acneus. Middle coxae more widely sepa- 

 rated than the anterior, the mesosteruum being more or less pro- 

 tuberant, either truncate or emarginate. The posterior coxae are 

 scarcely dilated internally. Tibiae with minute terminal spurs, in 

 two genera. Tarsi slender, slightly dilated in Dicranopselajphus, 

 claws variable. 



The species composing this tribe are of oval moderately robust 

 form with teguments of firmer consistence than in Helodes or Cyphon. 

 The genera in our fauna all agree in having the terminal joint of the 

 palpi simple, without appendages. In Euhrla the last joint of both 

 palpi is furnished with three short spines and in the Dicranopselaphus 

 of Mexico with two. 



The most curious fact noticed is the sexual difference in the claws 

 of Ectopria. In the female the claws are simple at tip, at base a 

 broad tooth rectangular in front; in the male the tip is bifid. Gueriu 

 describes the claws of Dicranopselaphus as tridentate but this is not 

 exactly true, he probably saw the claws obliquely instead of in front. 

 As I have seen only males of this genus I do not know if they differ 

 sexually as in Ectopria, but it is probable that this is the case. The 

 claws of Eubria examined by me have no basal tooth as in Ectopria, 

 but the anterior claw on each pair of legs is bifid at tip, (PI. I, fig. 9), 

 the posterior entirely simple; my material being entirely insufficient 

 I am unable to say whether the claws differ in the sexes. As the 

 genus does not occur in our fauna this is left for European determina-' 

 tion. The bifid structure of the claw can only be detected by a com- 

 paratively high power and by viewing the claw directly on end.
