184 Memoirs on the Coleoptera 



as in vernicatus but relatively somewhat larger, the sides feebly 

 sinuate behind and not becoming subparallel but oblique to the 

 base, the angles more broadly rounded; sides before the slightly 

 ante-median prominence more converging to the apex than in the 

 preceding, the impressions and foveae almost similar; base narrower 

 than half the maximum width, not equal thereto as it is in vernicatus; 

 elytra larger, four-fifths longer than wide, nearly twice as wide as 

 the prothorax, more evenly oblong-suboval, widest more nearly at 

 the middle and more rapidly arcuately narrowing posteriad, the 

 humeri less strongly rounded; sculpture as in vernicatus, less coarse 

 than in cordatus; tarsi very slender. Length (9 ) 13.3 mm.; width 

 5.4 mm. California (Sta. Cruz Mts.), — Harford. 



rufitarsis n. subsp. 



It is impossible at present to determine the true relationship of 

 these three forms, all of which are very rare individually, and it 

 seems appropriate to suggest for them the status of subspecies 

 until it becomes possible to gather more material evidence. The 

 larger head, wider and more transverse prothorax and coarser 

 elytra! sculpture of the single example of cordatus are not essentially 

 male characters, for the elytra in the single female of vernicatus dire 

 narrower than in this male, a condition unknown in this genus 

 within the limits of true species. 



Trechus Clairv. 

 In a short review of our Trechus species in the preceding number 

 of these Memoirs, I unfortunately overlooked some descriptions 

 by Mr. Schaeffer (J. N. Y. Ent. Soc., 1915, p. 47) and quite natur- 

 ally have had some solicitation in regard to synonymy, but on 

 reading the author's references to T. utahensis and coloradensis, 

 am convinced that neither of these could be included in my material; 

 the former is far larger than any of my species, and coloradensis, 

 so far as can be judged by the four published lines, also differs, the 

 elytra being as in chalyhceus and not dilated, oval and relatively 

 much wider, as they are in saxatilis Csy., said to have been taken 

 in Colorado by Levette. In regard to borealis Schf., however, it 

 seemed at first that hrumalis Csy., also from Labrador, must be 

 synonymous; so, on my request, Mr. Schaeffer very obligingly 

 sent me two specimens of borealis, one, typical, from Battle Harbor, 

 Labrador, the other from Port aux Port Bay, St. George, New- 

 foundland, both, as well as the type of hrumalis, being males. The 

 two specimens sent by Mr. SchaefTer represent two distinct species,
