200 Memoirs on the Coleoptera 



scutellar stria long, oblique; intervals broadly convex, strongly so on the 

 declivity. Length (9) 10.3 mm.; width 4.6 mm. Colorado (Mesa, 

 Boulder Co.), — Foster. Communicated by Prof. Cockerell. 



This species may be placed near ventricosa, but differs in the 

 virtually unconstricted neck and almost flat eyes; from diffinis 

 it differs in its more abbreviated form and convex strial intervals, 

 also in the less clearly biimpressed lateral* punctured pronotal 

 area at base. 



From material recently received from Mr. Wade, I note that 

 Amara fallax Lee, extends entirely across the more northern 

 parts of the subarctic regions, while the smaller hesperia occurs in 

 California and Oregon, Nevada, Utah, southern Colorado and New 

 Mexico, the contrasting series of 29 and 25 specimens demonstrate 

 their validity as species. 



Diplocheila Brulle 



In Mem. Col., page 146, I gave a review of the species of this 

 genus then known to me. Since that time several additional 

 species have come to hand, among which I am glad to number 

 Canadian examples of laiicollis and striato punctata of LeConte, 

 as well as examples of alternans Csy., very kindly given me in 

 exchange by the Dominion Entomologist, Dr. C. Gordon Hewitt, 

 from series discovered among the material shown me while on a 

 recent visit to Ottawa. There is also among these recently acquired 

 species, one belonging to the obtusa group of LeConte, distinguished 

 by the rounded thoracic angles and absence of dorsal elytral punc- 

 ture, but differing from obtusa in having scarcely a vestige of trans- 

 verse pronotal impressions, said to be unusually distinct in that 

 species. I have restored the original spelling of the generic name, 

 overlooked in my former revision of the species. The new forms 

 may be described as follows; 



Diplocheila procera n. sp. — Elongate-suboval, moderately convex and 

 shining throughout above, black, the legs and tarsi black; head rather 

 large, somewhat longer than wide, four-sevenths as wide as the pro- 

 thorax, with prominent eyes, the anterior impressions large and within a 

 broad declivous depressed area; epistoma rather narrowly and deeply 

 sinuate at tip, the suture distinct, transverse, finer and oblique at the 

 sides; labrum with the lobes coarsely setose at tip, the right lobe larger 

 and longer than the left; mandibles thick; palpi long and slender, the 

 last joint evidently shorter than the third; antennae slender, ferruginous,
