AMERICAN COLEOPTERA. 131 



higher on the front near the inner margin of the eye. The last 

 palpal joint is nearly parallel, widest at about the middle; the ely- 

 tra are somewhat irregularly seriate punctate ; middle coxse a little 

 less narrowly separated ; fifth ventral segment longer; tibial spurs 

 differing in the sexes. 



We have but a single species, which is so well known as to need 

 only a brief description. 



1. E. luiineralis Lee— Oblong, moderately elongate, dull black; protborax 

 except basal and apical margins, and the humeral umbone reddish yellow. Head 

 granulate and rather densely clothed with fulvo-cinereous hair. Prothorax with 

 fulvous hair, surface granulate, disk obtusely elevated. Elytra alutaceous. 

 closely rather coarsely striate-punctate, the rows somewhat irregular, especially 

 toward the suture; intervals narrow, feebly convex, pubescent, the humeral one 

 a little more conspicuously cinereous pubescent, giving the appearance of a nar- 

 row vitta. Length 4-5A mm. 



This pretty species occurs in the North Atlantic States and 

 Canada extending west to Michigan and Kentucky. The statement 

 in the "Classification " that the tibia? have but a single spur is erro- 

 neous. There are two spurs in both sexes, and in the female these 

 are of the usual size; in the male the inner one is much enlarged 

 and the smaller outer one being close to it may easily be overlooked. 



Dryophilini. 

 The members of this tribe agree in having the head only moder- 

 ately deflexed, the prothorax not excavated beneath for its recep- 

 tion, the legs not received in cavities, the hind coxse rather feeblv 

 sulcate. The antennae are 11-jointed, except in two species of Ervo- 

 bius, the three outer joints more or less dilated and elongated in all 

 our genera. They are not received between the front coxa?, which are 

 either contiguous or narrowly separated. The seven genera repre- 

 sented in our fauna vary much in appearance as well as in details 

 of structure. They separate as follows: 



Front coxae only moderately prominent, separated by a distinct prosternal process. 

 Tarsi broad, prosternum short before the coxae. 



Intermediate joints of antennae subequal Xestobium. 



Intermediate joints of antennae unequal, the fifth and seventh wider and 



more elongate Utobium. 



Tarsi relatively narrow. 



Prothorax margined at sides. 



Antennae 10-jointed, prosternum very short before the coxae, mesosteriium 

 vertical between the coxae MicrozogUM.
