Under Ormixeus \ \\m{e all those small Aiilliriliii/dc ■^\\w\\ have a sinuate eye, 

 convex irons, and deeply concave antebasal carina. The S 6 have an acute 

 spur-like tooth at the ajiex of the mid- and hindtibiae, or at least of the 

 midtibia. The genera erected by Leconte in 187() — namely, To.cotropis and 

 Gonops — cannot be separated from Ormisciiii {= Ildrmi.ffiix); at least, not by 

 the characters which Leconte mentions in the descriptions, these chariicters not 

 being constant for the supposed genera. Leconte says that the club of the antenna 

 of Onnisctii is " apparently solid." The three segments of the club fit indeed 

 so well together in several species of Ormisciis (but not in all) that one might 

 easily mistake the club for being solid. But his Onnisciif: is jierhaps not the 

 Or mini- IIS of Waterhouse. 



Eusjiliijnis, also described by Leconte, and put among the " Baxilropini,''' 

 quite correctly according to Lacordaire's classification, differs from Ormisais 

 hardly in anything else but the basal position of the carina. This differential 

 character is not even constant, there being some species among our nndescribed 

 material of which I can scarcely say with certainty whether they belong to 

 Eusp/ii/riis or to Ormisciis. The <?<? of JCusp/n/n/s have, as a rule, no spur-like 

 apical process on the mid- and hindtibiae. 



The basal or antebasal jiosition of the anterior carina of the protlmrax is of 

 no snch great classificatory importance as attributed to it in Lacordaire's .system. 

 The division of the " A/it/iri/jii/i's Pleurocrres^' into " Tropiih' rules'^ and " Basi- 

 trojndes" is quite artificial.

S. Black, legs more or less extended rnfnus, tarsi and base of antenna 

 brunnescent ; underside, jiygidium, and legs pubescent grey ; ui)]ierside co])])er- 

 colonr, very sparsely variegated with white hairs ; scutellum white ; base of suture 

 for a short distance white, this streak' continuous with an anteraedian oblong white 

 spot situated between first and third stripe. Antenna short, club less than twice 

 as long as broad. Frons more than lialf the width of the rostrum. Prothorax 

 nearly as long as broad, rounded anteriorly at side, densely punctate-reticulate, 

 carina not flexed forward at side. Elytra subcyliudrical, a little depressed 

 transversely before middle, rounded-declivous from middle to apex, regularly 

 punctate-striate, densely granulate. Pygiilinni a little longer than broad, rounded 

 at apex. Spur at apex of mid- and hindtibiae small.
