American Caraboidea 297 



This species may be allied to flaccidiis Horn, but is evidently 

 distinct, as there is no trace of a sinus before the thoracic angles, 

 this being specially stated as distinct m flaccidiis; it is more elongate 

 and slender than pennsylvanicus , where the second joint of the 

 anterior male tarsi is quadrate and exactly as wide as long, the 

 third slightly elongate; in pennsylvanicus, also, there is a distinct 

 sinus before the thoracic angles, and the elytra! striae are distinctly 

 impressed. 



Chlaenius blanditus n. sp. — Body slightly smaller and more abbreviated 

 than in pennsylvanicus, bright green throughout above and rather shin- 

 ing, the elytra not distinctly opaculate; under surface black, punctate, 

 the legs testaceous; head nearly as in pennsylvanicus but shorter and a 

 little broader, the antennae subsimilar; prothorax a fourth wider than 

 long, the sides parallel and evenly arcuate throughout, becoming just 

 visibly sinuate near the basal angles, which are slightly more than 

 right and narrowly blunt at tip; median line fine, lying within a broad 

 and feeble depression, the impressions obsolete, the fovese short, linear, 

 deeply impressed; surface strongly punctate, closely toward base, rather 

 loosely elsewhere; margins finely rufescent; base feebly bisinuate, a 

 little wider than the apex; elytra barely more than one-half longer than 

 wide, not one-half wider than the prothorax, in outline nearly as in 

 pennsylvanicus, the striae similar but almost impunctate, the intervals 

 flatter, with strong and asperate close-set punctures, the hairs a little 

 coarser, brighter fulvous; anterior male tarsi well dilated, the second 

 joint wider than long, the third about as wide as long. Length (cf 9 ) 

 9.7-10.0 mm.; width 4.0-4.4 mm. Utah (Vineyard), — Tom Spalding. 

 Three examples. 



Allied to pennsylvanicus but with shorter form of body and much 

 brighter green color above, also with broader anterior male tarsi, 

 the second joint in pennsylvanicus being exactly as long as wide, 

 quadrate, the third distinctly longer than wide; the prothorax is 

 more transverse and widest at the middle, and not behind the 

 middle as it is in pennsylvanicus; the elytral striae have much finer 

 punctures, sometimes almost invisible, and the interstitial punctures 

 are still stronger, rather closer and more asperate. In brevilabns 

 the anterior male tarsi are as in pennsylvanicus, the prothorax more 

 nearly as in blanditus, and the interstitial punctures are finer and 

 sparser than in either of these species; brevilabris is a little larger 

 and broader, with relatively larger prothorax. 



The following is appreciably distinct from tomentosus, but may 

 be regarded as subordinate for the present; the body is much 

 longer and narrower and the coloration is different:
