American Caraboidea 139 



genus but is larger, with more transverse prothorax and relatively 

 small head. 



The following species is allied rather closely to lecontei: 



Elaphrus devinctus n. sp. — Feebly convex, with rather broad hind 

 body; color obscure bronze above, cupreous beneath, metallic green 

 along the median parts and the entire abdomen; legs as in lecontei; head 

 distinctly narrower than the prothorax, finely, densely punctate, minutely 

 rugulose between the eyes; antenna; short and thick, nearly as in lecontei; 

 prothorax shorter, fully a third wider than long, the prominently rounded 

 sides becoming abruptly parallel in basal fifth; surface finely, very 

 densely punctate, feebly and transversely biimpressed toward the sides, 

 the fine median stria greatly biabbreviated; elytra a third longer than 

 wide, four-fifths wider than the prothorax, gradually broadly rounded 

 behind, the parallel and broadly arcuate sides with a small distinct sinus 

 just behind basal fourth; surface finely, very densely punctate, the large 

 foveae of the four series very distinctly defined; central umbones minute 

 but evident, each surrounded by a more obscure dark ring, the foveae 

 separated longitudinally by small and somewhat elevated polished spots, 

 the one at the suture just before the middle much the largest and oblong; 

 tarsi slender, bright metallic green. Length (9) 7-5 mm.; width 3.5 

 mm. Colorado (Wray), — Shantz. 



Distinguishable readily from lecontei by its more abbreviated 

 form, shorter parallel part of the prothorax at base, this in lecontei 

 being about a fourth the entire length, and by the more impressed 

 and more sharply defined elytral foveae. 



Notiophilus Dum. 



This genus was reviewed at some length by Mr. H. C. Fall some 

 years ago, so that at present it is only desirable to add several 

 recently discovered new forms, and to ofTer a few mildly critical 

 remarks. I am unable to understand, for instance, why Mr. Fall 

 did not place novemstriatus Lee, as one of the 7-striate series. 

 This is one of our smallest species, of notably slender form and 

 wide distribution, represented in my collection from Massachusetts 

 to Colorado. The striation between the frontal grooves is some- 

 what inconstant and apt to become irregular, but there are many 

 more specimens having seven striae than those with five or six, 

 thus warranting the name given by LeConte, who counted the two 

 coarse grooves in with the intermediate striae; LeConte noticed 

 five striae between the grooves in some examples, which he referred 

 to the much larger semistriatus.
