ClCINDELID^E AND CARABID.-E 189 



It may be that I do not have the true americana at all, as it is by 

 intimation said to be punctured as in venator, for it may be a 

 Georgian species sent by the elder LeConte. In this case americana 

 Csy., would still be undescribed. Individuals of the americana 

 type seem to be rare, though there are certainly a number of species. 

 I have two females, not mentioned above in the descriptions and 

 not mutually the same specifically; they are labeled "Colorado" 

 but possibly in error; one of them seems to match the assumed type 

 of venator rather well and the other is like americana Csy., in some 

 respects but distinctly differs in others. 



Helluomorpha Lap. 



The uniformly testaceous species of this genus with unelongated 

 prothorax, are very similar in general appearance among themselves 

 but are nevertheless distinguished by some good minor characters. 

 Texana Lee., is rather abundant in Clark Co., Kansas, and also in 

 Texas; it varies a good deal in size; ferruginea Lee., seems to be less 

 frequently taken and I have but two examples from Texas and 

 Jemez Springs, New Mexico. The three following allied species 

 have not yet been described : 



Helluomorpha latitarsis n. sp. Moderately depressed, rather shining, 

 testaceous throughout, the pubescence moderate and pallid, the hairs 

 from the series bordering the convex intervals oblique in contrary senses; 

 head scarcely four-fifths as wide as the prothorax, sparsely, irregularly 

 and not very strongly punctate, the eyes very prominent; antennae 

 rather short, broadly compressed, the joints beyond the fourth about 

 as long as wide, impressed and glabrous medially toward base; prothorax 

 slightly wider than long, the sides evenly and strongly rounded, converging 

 from about the middle, becoming parallel and nearly straight basally, 

 the angles rather acute and sharp, rendered slightly prominent by a 

 minute sinus just before them; base slightly wider than the apex, broadly 

 sinuate, becoming abruptly anteriorly oblique at the sides; apex feebly 

 sinuate medially, without lateral angles; surface linearly impressed along 

 the middle, rather coarsely but sparsely punctured throughout, finely 

 reflexed at the sides from apex to base and with a large deep latero-basal 

 impression; elytra two-thirds longer than wide, three-fourths wider than 

 the prothorax, slightly inflated posteriorly, the apices broadly and evenly 

 arcuate; surface with moderate glabrous costa?, separated by wider con- 

 cave lines, which are rather closely, not very coarsely and confusedly 

 punctate throughout; legs stout, the hind tarsi broad and flattened, the 

 third joint barely at all longer than wide and parallel-sided. Length 

 (cf) 15.0 mm.; width 4.8 mm. Arizona (locality not indicated).
