'618 Coleopterological Notices, VI. 



The species are moderatel}' numerous and those known to me 

 ma}^ be readil^y identified by the following characters : — 



8ii])f;enus I. 

 Conibius Lee. 

 Humeral augles of the elytra more or less distinctly prominent. 



Body narrow and elongate; jironotum densely punctate. ..paralleliis Lee. 

 Body less slender, the elytra more deflexed and vertical at apex 

 Bicolored, the pronotum sparsely punctured toward the middle. 



mei'iatus Lee. 

 XTnicolorous, the pronotum more coarsely and densely punctured; body 



nearly twice as large giiailaliipeusis Csy. 



Humeral angles rounded or at least obtuse. 



Antennte moderately long; prothorax nearly one-half ^vider than long and 



very feebly narrowed toward base ii ii i f o I'lii i s Csy . 



Antennae shorter; prothorax much more transverse, four-fifths wider than 

 long, strongly narrowed toward base, the side margins narrowly sub- 

 explanate Iiriiniiipes Champ. 



Subgenus IL 

 Ooconibius n. sg. 

 Elytra oval, the lateral edges visible throughout from above and finely re- 

 flexed, more noticeably so near the base and toward apex opaciIS Lee. 



Subgenus HI. 

 Euconibius n. sg. 

 Pronotum broadly subexplanate toward the sides; fine side margins of the 

 elytra visible throughout from above as usual but not reflexed. 



gagates Horn 

 Notibius reflexus, recently described by Dr. Horn from Lower 

 California (Col. Baja Cal., p. 429), cannot be distinguished from 

 opacus hy any detail given in the original diagnosis. 



IVOt'IBIOTES n. gen. 



The species of this genus have a characteristic facies, which will 

 render their identification tolerably certain. The six representa- 

 tives known to me may be recognized b^' the following table : — 



Basal angles of the prothorax rather l)roadly oblique at the base, large and 

 posteriorly prominent ; pronotum more obscurely sculptured, the sides 

 less rounded. 

 Third antennal joint fully twice as long as wide. 

 Elytral sulci deep; legs rather slender. 



I'ronotum somewhat coarsely and very closely punctured. 



gi'aii Hiatus Lee.
