what comminuted, the intervals flat. Length 6.0 mm.; width 2.4 



mm. California (Lake Co.), — Fuchs quadricollis Lee. 



Prothorax as long as wide or very nearly 2 



2 — Body larger than in the preceding, moderately convex, shining, 

 castaneous, piceous beneath, with the legs testaceous; head rather 

 longer than wide, three-fourths as wide as the prothorax, the eyes 

 rather well developed but much less prominent than in the preceding, 

 the long converging tempora nearly straight; front as in the pre- 

 ceding but with the lateral plicae more numerous; antennae fusco- 

 rufous, clearer basally, distinctly less than half as long as the body; 

 prothorax in general outline and broadly reflexed diaphanous side- 

 margins, nearly as in the preceding, the transverse rugulae rather 

 closer and more numerous; median stria fine, biabbreviated ; apex 

 much narrower than the base, more deeply sinuate than in quadri- 

 collis; basal foveae similar, smooth, at lateral fifth; elytra nearly 

 as in quadricollis in outline but four-fifths wider than the prothorax, 

 and with the fine and slightly uneven striae rather deeply impressed, 

 the intervals broadly convex, not perfectly flat as in the preceding; 

 dorsal punctures not evident. Length 6.6^7.8 mm.; width 2.35— 

 2.8 mm. Maryland and Lake Superior (Marquette and Bayfield). 



Eight examples piceus Dej. 



Body smaller and narrower than in the preceding, castaneous, the under 

 surface and legs paler, polished, the elytra more strongly micro- 

 reticulate than in piceus; head four-fifths as wide as the prothorax, 

 shorter, as wide as long, but otherwise similar, the eyes more promi- 

 nent; antennae testaceous, slender, a little less than half as long as 

 the body; prothorax shorter, a fourth wider than long, otherwise 

 nearly similar, except that the sides are more oblique posteriorly; 

 margins broadly, subequally reflexed throughout and diaphanous; 

 elytra similar in general outline but only three-fifths wider than the 

 prothorax, the striae differing in being broadly and feebly impressed 

 and obtuse, the intervals very feebly convex, the dorsal punctures 

 not observable and probably wanting in the genus. Length 6.0 

 mm.; width 2.1 mm. Mexico (Colonia Garcia, Sierra Madre Mts. 

 Chihuahua), — Townsend *chihuahu8e n. sp. 



I am unable to understand on what ground quadricollis has been 

 placed as a variety of piceus; it is altogether distinct in its shorter 

 head, mo;-e prominent eyes, transverse and relatively much broader 

 prothorax, feeble striae, perfectly flat intervals, smaller size and 

 many other characters. It is not advisable to give the name 

 quadricollis, unless the prothorax approximates a square, which 

 is not by any means the case in this species. I am unable to dis- 

 cover any clear trace of dorsal punctures on the elytra, which is 

 another obvious distinguishing feature of this genus.
