140 MEMOIRS ON THE COLEOPTERA 



rather be regarded as a variety of that species; this alone would 

 indicate the true variegatum to be the species described as post- 

 fasciatum by Hamilton; but the subject is conclusively set at rest 

 by the length ascribed to variegatum by its author \ inch, or 5 

 mm. which suits postfasciatum perfectly, but is much too great for 

 even the largest known example of patruele or of posticum, although 

 Say apparently included some of these forms in his general concep- 

 tion of variegatum. 



It is probable that rubiginosum Lee., which is unknown to me, 

 belongs to the same section as novellnm, a very peculiar minute 

 species from the Sierras of California; rubiginosum occurs in the 

 mountains of Colorado, at Garland. 



In the vile section, no one of the above described species can be 

 identified definitely with any one of the three already known. I 

 have personally compared the type of parabile with that of vile, 

 from San Diego, and the two differ greatly, especially in the much 

 broader prothorax of the former, and also of that of the still more 

 minute and slender diligens. In regard to morulum Lee., recalling 

 concolor in form and habitus, as intimated by Hayward, and in- 

 habiting more northern regions in Hudson Bay Territory, little fur- 

 ther need be said, as I have seen nothing resembling it. It only 

 remains to compare the type of dyschirinum Lee., said to be from 

 the country east of old Fort Colville; it is possible that either agi- 

 tabile or atrolucens may be identical, but in view of the inadequate 

 character of all accessible descriptions, absence of the type and 

 manifold plurality of allied species, it would be useless to assign 

 LeConte's name to any one of those here described; it would at 

 best be but a guess and, in case of future proven identity, it will 

 be easy to place the proper name in synonymy. Attention should 

 be called to an evident mistake by LeConte in giving .19 inch or 

 4.7 mm. as the length of dyschirinum; this is corrected by Hayward, 

 who gives the length as 3 to 3.75 mm. 



Vinmilum was identified by Horn and Hayward as scintillans 

 Bates, from the southern parts of Mexico, presumably because of a 

 remark made by Bates to the effect that specimens assumed by 

 Horn to be vinnulum, departed so little from scintillans as to be 

 unworthy of a distinctive name, differing only in the striae being 

 less impressed and losing their punctures at a greater distance from
