pared with mucronatum, and I have seen no reference to its 

 prosternal structure. 



Anepsyra n. gen. 



A distinct genus seems to be necessary for Elaphidion tenne and 

 Aneflus volitans of LeConte, for which the above name is suggested. 

 The very conspicuous spine of the third antennal joint, which is 

 two-thirds as long as the fourth joint in both species, together with 

 the elongate prothorax and the vestiture of erect flying hairs, 

 indicates that the genus may be suggestive in some measure of the 

 tropical Psyrassa. Both species seem to be rare, inhabiting 

 respectively southern Texas and Lower California. 



Pseudibidion n. gen. 



This name is suggested for a genus to receive the species described 

 by Randall under the name Stenocorus unicolor and subsequently 

 having several other resting places in the taxonomic scheme, until 

 finally included as an aberrant ElapJridion in our recent lists. 

 It is of an isolated facies among our species, and the characters 

 given in the table set forth its more salient peculiarities. 



Aneflomorpha n. gen. 



This genus is a moderately large one. Besides subpubescens Lee., 

 it will comprise, among the described species, lengi Schf., which has 

 the peculiar Ibidion-like carina of antennal joints 3-6 well developed 

 as in imispinosa, described below, Elaphidion lineare of LeConte, 

 from California, the Mexican Aneflus cylindricollis of Bates and 

 possibly Aneflus calvatus Horn. Elaphidion aculeatum also seems 

 to be best assigned to Aneflomorpha, although the antennal and 

 elytral spines appear to be more developed than is the rule in this 

 genus, and there would seem to be a greater development of the 

 so-called flying hairs on the upper surface, these being absent or 

 scarcely visible in the normal species, such as subpubescens and 

 those described below. Levettei Csy., can likewise be appended to 

 this genus as a very aberrant member, having the same outline and 

 general structure but differing very strikingly from normal forms 

 in sculpture and vestiture, the small decumbent cinereous hairs 

 of the elytra being aggregated into about four dense vittse on each
