50 COLEOPTERA RHYNCHOPHORA. 



which is quite small on the posterior pair ; claws with a moderately 

 long tooth, tibiae straight. Length 2 mm. 



Type. — From Brownsville, Texas. 



Described from a single 6^ example which seems to be 

 most closely allied to sulciirons, but distinguishable by the 

 coarser and denser vestiture, longer beak, paler antennae, 

 and finer and less coarsely punctate striae. 



Since writing the above I have examined the LeConte and 

 Dietz Collections, and have come to the conclusion, already 

 expressed in a note on sulcifrons, that this latter is not sepa- 

 rable from musculus, which name may therefore be substi- 

 tuted for sulci fro7is in the above paragraph. 



The species which I have here described seems to be iden- 

 tical with two Texan specimens included by Dietz with his 

 vespertinus, the type of which comes from Jacksonville, Fla. 

 In this type the frontal fovea is not obviously elongate (Dietz 

 says sulcate in his description but foveate in his table), the 

 vestiture is nearly white, surface lustre dull, not very coarsely 

 pubescent above except in condensed areas, where the hairs 

 are squamiform, but beneath they are more properly scales, 

 and are very dense on the under side of the head and sides of 

 the body. Above they are denser on the median line of the 

 prothorax and in two transverse elytral fasciae, the anterior 

 consisting of three spots occupying intervals 4-6-8, the poste- 

 rior less distinctly defined but seemingly similarly formed. 

 The insect is in good condition but apparently somewhat 

 immature. 



In the two Texan examples which follow the type of ves- 

 pertinus the vestiture of the upper surface is ochreous, more 

 uniformly squamiform, the fasciae not evidently broken into 

 spots ; vestiture beneath very much the same in character as 

 above and not conspicuously more scale like, elytra dis- 

 tinctly shining. Both specimens are 9 's, with the antennae 

 inserted slightly beyond the middle of the beak. 



A. basidens n. sp.— Robust, oval, deep black ; antennae testace- 

 ous at base, becoming gradually darker externally, the club piceous. 

 Above subglabrous, the pubescence excessively short, fine and sparse, 

 except for the scutellum and a small area of equal size posteriorly con-
