the thorax is nearly as wide as the widest portion of the tliorax, whereby the 

 latter appears small. A specimen from the St. Petersburg Museum, sent me as 

 a type, is not allied at all to this species, but rather to E. cordata. 



It is well to mention here that the typical parricollls resembles a 

 large scabrosa, and the latter can easily be confused with cordata. 

 A collector with Q.ny diagnostic acumen at all will not make such 

 mistakes. 



To satisfactorily Avork out the races of parrlcoU'is has given me 

 more trouble and consumed more time than any other whole sub- 

 genus, and while I feel that I might be wrong in some of my conclu- 

 sions, I have Mr. Blanchard's careful comparisons to support my 

 opinions, Avhich are, besides, based upon the study of large series of 

 specimens and much careful dissection of material. 



General ohservations. — The mentum, pro- and mesosterna as in 

 parvicollis. The metasternum laterally between the coxse is as long- 

 as the width of a mesotibia at apical third. 



The abdominal process is subquadrate and about a third of its 

 width broader than the metasternal salient. 



In the male the process is equal in length to the post-coxal part of 

 the first segment and equal to the second ; the latter is a fourth longer 

 than the third, which is slightly longer than the fourth. 



In the female the post-coxal part of the first segment of the 

 abdomen is equal in length to the third, the latter equal to that of 

 the process ; the second is twice as long as the fourth. 



The tarsi are slender and moderate in length.

ELEODES HOPPINGII, new species. 



Oblong-oval, about twice as long as wide, somewhat depressed, 

 surface rather dull, pimctures of the head and thorax scarcely coarse; 

 elytral sculi)turing rather fine and dense, muricato-granulate lat- 

 erally, i)unctures throughout finely setigerous. 



Head less than twice as wide as long, rather evenly convex, feebly 

 impressed laterally, obsoletely so along the frontal suture, the latter 

 not evident; surface densely punctured. Antenna' short, attaining 

 the posterior fourth of the prothorax, moderate in stoutness, feebly 

 compressed and slightly widened in the outer four joints, third joint 

 equal to the next two combined, fourth to the eighth inclusive sub- 

 equal in length and scarcely longer than wide, the eighth triangular, 

 ninth and tenth feebly transversely oval, eleventh short-ovate. 



Pronotuni transversely oblong-oval, widest at the middle, less to 

 about a half wider than long; disc scarcely moderately and evenly
