and antennae ferruginous ; elytra each with a rufescent cloud from near the 

 humerus to the middle; pubescence fine, subrecumbent, sparse but rather 

 long. Head fully four-fifths as wide as the prothorax, deeply impressed and 

 bistriate in the middle between the eyes, the epistomal depression scarcely 

 connected by a groove; eyes large, very convex, the tempora scarcely more 

 than one-half as long, very convergent, broadly arcuate ; antennae three-fifths 

 as long as the body, moderately stout, the outer joints not quite three times 

 as long as wide, equal, eleventh one-half longer than the tenth. Prothorax 

 not quite one-third wider than long, widest at apical third ; sides strongly 

 constricted behind, becoming abruptly parallel in basal fifth or sixth ; base 

 truncate, much wider than the apex ; disk finely, very sparsely punctate, 

 feebly but distinctly impressed along the median line from the apical margin 

 to the deep transverse antebasal fovea. E/i/tra not quite as long as wide, dis- 

 tinctly longer than the head and prothorax ; humeri broadly exposed ; sides 

 moderately divergent ; outer apical angles rather broadly rounded ; disk not 

 coarsely, somewhat sparsely punctate, broadly impressed along the suture 

 toward base. Abdomen barely as wide as the elytra and much shorter, 

 polished, finely, sparsely punctulate ; border moderate. Length 4.4 mm. ; 

 width 1.55 mm. 



New Mexico (Las Yegas). 



Distinguishable from ovipennis by its smaller size, longer elytra 

 with much less divergent sides and many other characters. The 

 fourth joint of the maxillary palpi in the single female before me 

 is very nearly as long as the third, fusiform and gradually pointed, 

 and by this character, as well as the stouter antennae and much 

 finer, sparser punctures of the head and pronotum, it can be readily 

 separated from plagiatus or any of its varieties. 



In the female of ovi2Jen7Hs the humeral width of the elytra is not 

 more than three-fourths of the subapical, while in nubilatiis the 

 ratio is fully four-fifths. 



G. debilis n. sp. — Highly polished, very sparsely and rather coarsely 

 pubescent, pale flavo-testaceous. the head a little less pale and the abdomen 

 picescent. Head scarcely visibly narrower than the prothorax, the eyes 

 small, strongly convex, scarcely longer but very much more prominent than 

 the tempora ; surface very finely, remotely punctate, the median impression 

 and diverging lines distinct, not connected with the strong epistomal depres- 

 sion ; ocelli extremely feeble ; fourth joint of the maxillary palpi almost as 

 long as, but much narrower than, the obconical third; antennae rather stout, 

 filiform, three-fifths as long as the body, the tenth joint twice as long as wide, 

 three-fifths as long as the eleventh. Prothorax scarcely visibly wider than 

 long, rounded at the sides anteriorly, feebly, gradually narrowed behind, 

 feebly constricted at basal fourth ; disk finely, very remotely punctate, with 

 a median impression attaining neither the apex nor the subbasal transverse 

 fovea. Elytra small, three-fourths longer than the prothorax, and, near the
