nent in the apical two-thirds; the tifth joint is alone margined 

 beneath. 



Propinqua is related to caseyi, from which it differs in its 

 coarser sculpturing, more strongly sinuate sides of the prono- 

 tuni and many other details which can be determined by com- 

 parison of the two descriptions. The elytra are noticeably 

 pubescent. 



Elcodcs hrcvisctosa, nuncnmacheri, verrucitla and propin- 

 qua belong to the subgenus Blapylis.

In order to express the relationships of the races of his- 

 pilabris properly, it becomes necessary to consider the smooth 

 form {forma lacvis) as a race instead of a forma. The origi- 

 nal diagnosis given in my Monograph of the Eleodiini is as 

 follows : 



Robust, integuments decidedly black, thick and alutaceous, also quite 

 smooth. Thorax rather large. Elytra usually evenly convex from side 

 to side, sulci very shallow and subobsoletely punctured ; intervals 

 very feebly convex and with a single row of widely spaced punctures, 

 that become minutely but distinctly muricate laterally and on the 

 apical declivity. Legs somewhat slender.

While there are verv close resemblances between the two 

 sexes as to general form, a difference is obvious. The males are 

 slightly narrower and the abdomen less convex. E. Jiispila- 

 bris forma elongata of the Monograph (Bull. 63, U. S. 

 Nat. Mus.) is a variation of imitabilis and not of the type- 

 species. Its relationship may be expressed as follows : 



E. hispilabris, var. imitabilis, forma elongata. 



The essential diagnostic characters are as follows : — General form 

 distinctly elongate and narrower as compared with the typical race.
