The two species crurale and dubitans of LeConte, are considered 

 to be synonymous by Mr. Hayward, but my studies do not confirm 

 this; on separating the two forms into series and comparing them 

 in this way, it can be observed that crurale is a materially larger 

 species, relatively narrower, much more elongate and with a larger 

 prothorax, and that there is but seldon a very small feeble pale spot 

 behind the humeri, while in dubitans nearly all the specimens have 

 at least a well defined trace of the spot, which usually is moderately 

 large and well defined. Although the posterior spot in pugetanum is 

 usually obsolete and at best very vague, the species can be distin- 

 guished from either of the more southern LeContean species by its 

 heavier build and broader elytra, as well as the much larger and 

 more conspicuous post-humeral spot. In gregale the posterior spot, 

 though small, is usually evident but sometimes becomes completely 

 obsolete. I am not positive that the Utah example above described 

 as prczcinctum Lee., is correctly identified, not having compared it 

 directly with the type; it is a very distinct species in its dull elytra, 

 with unusually long and feeble striae. The Elko specimens taken 

 by Wickham, were evidently confounded with prcecinctum by Mr. 

 Hayward; they are noted above under the name veridicum. That 

 author also confounded the Colorado form, probably named vegetum 

 above, with mutatum, the two are widely distinct however. Jucun- 

 dum Horn, from Arizona, must be a very isolated species; it is un- 

 known to me at present. 



Group XV sulcatum 

 Subgenus Paralopha nov. 



In general characters, including habitus, the single species of this 

 group known to me is allied most closely to the following assimile 

 group, resembling it in style of ornamentation, having the charac- 

 teristic small posterior external spot, but the converging frontal 

 sulci do not unite at the anterior margin of the epistoma as they do 

 in the assimile group, and have the unique peculiarity, so far as 

 the American fauna is concerned, of being evenly double through- 

 out their extent. Dr. Blaisdell places his Bembidion continuum
