Platynin^ 93 



by LeConte under the name consimilis, afterward changed to 

 vicina by Gemminger and Harold; the original description states 

 that it is materially larger than obsoleta, being 8 mm. in length: 

 in the Brooklyn Bulletin this length was however subsequently 

 reduced to 7 mm., which is probably nearer the truth; it is said 

 to differ from obsoleta in having the elytra more truncate at tip 

 and with deeper stria?; the type was found on Michipicoton Island, 

 Lake Superior. Harpalus hogemanni Gyll., is a European species 

 and I doubt its occurrence on this continent; in the latest European 

 catalogue, however, obsoleta Say, is said to be a synonym of 

 Agonum bogemanni, without doubt incorrectly, as we have a 

 number of allied though apparently distinct species. Our species 

 are moderately numerous and, so far as known to me, are as follows: 



Elytra densely opaque, with motded and sericeous lustre; dorsal punc- 

 tures about five, sometimes four, small and submuricate; pronotum 

 with fine dense strigilate sculpture, the basal angles well defined; 

 thoracic foveae before the middle near lateral fourth always evi- 

 dent • -2 



Elytra not opaque, always stroBgly shining; pronotum sometimes with 

 feeble and not dense transverse rugulae, but never with the close 

 confused sculpture of the preceding section 4 



2 — Elytra notably elongate, fully one-half longer than wide, the sutural 

 tips subangulate and narrow; color deep black above and beneath, 

 the under surface strongly shining, the legs and palpi black; head 

 fully as wide as long, fully four-fifths as wide as the prothorax, 

 with very prominent eyes; surface partially strigilate but smooth 

 at the middle; antennae very slender, black throughout, barely half 

 as long as the body; prothorax one-half wider than long, widest 

 and at the sides subprominently rounded before the middle, the 

 sides thence less arcuate before and behind, becoming gradually 

 somewhat sinuate before the obtuse but rather sharp angles, finely 

 reflexed, more so at base, the latter barely as wide as the feebly 

 sinuate apex, strongly oblique outside the peduncle of the hind body; 

 anterior impression feeble but evident, the stria not quite entire, 

 deep and distinct; foves having the form of large and feeble in- 

 definite depressions of the surface; elytra perfectly parallel, with 

 very feebly arcuate sides, rapidly rounding at base, rapidly somewhat 

 obtuse at apex, with distinct sinus; striae fine, feebly impressed, 

 feebly and not closely punctulate; intervals not quite flat, seri- 

 ceously and unevenly opaque; dorsal punctures small but lying 

 within rather large and feeble depressions; anterior male tarsi very 

 feebly dilated. Length (cf) 5.8-6.5 mm.; width 2.1-2.3 mm.

Elytra much less elongate, always less than one-half longer than wide, 

 the sutural tips broadly rounded 3
