AMERICAN COMPONENTS OF THE TENTYRIIN^ 515 



me in actuality ; they are perfectly congeneric with texanus and 

 angularis and are, in fact, so similar to our types in general 

 form, sculpture and coloration, as to be discriminated only 

 under more or less careful observation. The position of the 

 other species is simply inferred from the original descriptions 

 and are therefore to some extent provisional. 



EmmenastiLS parallelus, tenebrosus^ guatemalensts, subap- 

 terus^ seriatus, niexicanusy vicinus and ambiguus, are to be re- 

 ferred to typical Hylocrinus, the last with considerable doubt 

 however. The first three are represented in the material sent 

 by Mr. Champion and are exactly congeneric with longulus Lee. 



Emmenastus 7nancus, curitis, glabrattis, lentus, rugicollts, 

 ptilvinatus , pict'pes, and ellt^ticus are members of the genus 

 Steriphamcs, and the first four are before me at present. Len- 

 tus has the antennae unusually long and slender and glahratus 

 has the eyes unusually deeply emarginate and the antennae a 

 little shorter. 



Emmenastus stolidus is altogether exceptional in the Eury- 

 metoponini, in having the eyes completely divided, more through 

 the greatly extended posterior canthus than any unusual de- 

 velopment of the anterior, the latter intruding upon the eye 

 but little more than in normal species of Steriphanus. This 

 character, in connection with the rounded basal angles of the 

 prothorax and sparse vestiture of long stiff hairs on the under 

 surface of the tarsi, renders it necessary to propose a new genus 

 for stolidus, which may take the name Steriphanides (n. gen.). 

 The form of the body is more evenly elliptical than in Steri- 

 phanus, approaching that seen in Cryptadius and Stictodera^ 

 but the sculpture is exceptionally feeble. The basal joint of 

 the hind tarsi is evidently longer than the fourth. 



Emmenastus foveicoUis, IcevicolHs and confusus are repre- 

 sented among the material and belong to Ditaphronotus, as 

 stated before under that genus. The type described on p. 341, 

 under the name chanipioni, is allied to foveicoUis, but differs in 

 its more abbreviated form, more rounded sides of the prothorax 

 and elytra, more coarsely punctured and more impressed elytral 

 series, subopaque and not strongly shining integuments and 

 other characters. The convexity of the body is not especially
