HARPALIN.E 1 1 1 



width 3.0-3.35 mm. Wisconsin (Bayfield), Wickham. Five ex- 

 amples lacustris n. sp. 



Form slightly stouter, the female scarcely differing from the male in 

 outline, shining, black throughout above, the elytra (9) sericeo- 

 opaque; under surface and epipleura black and shining, the cephalic 

 appendages pale testaceous; head rather evidently more than half 

 as wide as the prothorax, nearly as in the preceding but with the 

 minute foveae more lineiform, the antennae slender; prothorax two- 

 fifths wider than long, the sides subevenly and rather strongly 

 arcuate, slightly converging posteriorly but more so anteriorly, the 

 apex deeply sinuate, with rather prominent and narrowly rounded 

 angles and much narrower than the base, which is transverse and 

 evenly margined, the angles nearly right but well rounded; surface 

 throughout nearly as in lacustris, the linear and broadly impressed 

 foveae very evident (cf) or obsolescent (9), punctureless; elytra 

 throughout nearly as in lacustris, except that the striae (c/ 1 ) are 

 slightly more impressed, the intervals not quite flat though usually 

 perfectly so in the female; hind tarsi nearly similar. Length (d* 9 ) 

 7.7-9.0 mm.; width 3.15-3.7 mm. Colorado (Boulder Co.). Thirteen 

 examples. Allied to lacustris but stouter and differing in the very 

 much less anteriorly narrowed prothorax coloradensis n. sp. 



40 Body oblong-oval, rather feebly convex, shining, black above and 

 beneath, the elytra (9) only faintly alutaceous; head but slightly 

 more than half as wide as the prothorax, the eyes prominent, the 

 antennae slender and testaceous and the foveae very minute; pro- 

 thorax nearly as in nitidulus, two-fifths wider than long, the sides 

 evenly and rather strongly arcuate, more converging apically than 

 basally, the apex deeply sinuate, with narrowly rounded and rather 

 prominent angles and very much narrower than the base, which is 

 transverse, finely margined and feebly bisinuate, with the angles 

 broadly rounded; surface feebly convex, steeply declivous at the 

 sides anteriorly to the very fine re flexed edge, the very fine gutter 

 not modified appreciably posteriorly, the foveae linear, nearly obso- 

 solete, feebly and broadly impressed, with a few punctures basally; 

 elytra two-fifths longer than wide, oblong, just visibly wider than 

 the prothorax in either sex, abruptly very obtuse at apex, the striae 

 feebly impressed, with very slightly convex polished intervals (cf) 

 or perfectly flat, with finer and more superficial striae (9 ), the sinus 

 broad and feeble but very obvious; basal joint of the hind tarsi 

 equal in length to the fifth. Length (cT 9 ) 7.4-8.0 mm.; width 2.9- 

 3.2 mm. New Mexico (Las Vegas and Fort Wingate) and Arizona. 

 Female not quite so large as the male as a rule. Ten examples. 



ellipsis Lee. 



Body stouter and more oblong, moderately convex, very shining, black 

 above and beneath, the anterior and middle male tarsi, antennae and 

 palpi pale testaceous; head barely more than half as wide as the 

 prothorax, the eyes moderately prominent, the antennae slender and 

 the foveae minute, rounded, perforato-punctiform and not quite 

 adjoining the suture; prothorax shorter than in the preceding, being 

 one-half wider than long but otherwise similar throughout; elytra
