and sparse, the interspaces shining. Abdomen rather coarsely and sparsely 

 punctate, the pubescence fine, rather long, pale and distinct. Legs long. 



Male. — Unkno w n . 



Length 7.7 mm. ; width 4.1 mm. 



Lower California (Cape San Lucas). Cab. LeConte. 

 The type is unique and is probably a female. It is the largest 

 species of the genus which I have been able to study. 



U. fimbria tus n. sp. — Elliptical, strongly convex and shining, piceous 

 throughout ; pubescence short and very robust, moderately dense, pale luteous 

 and conspicuous. Head strongly transverse, feebly convex, somewhat coarsely 

 and not very densely punctate ; epistoma very deeply sinuate ; upper lobe of 

 eyes moderate ; antennje slender, nearly as in obliquus but much longer than 

 the prothorax. Prothorax more than twice as wide as long ; apex three-fourths 

 as wide as the base, rather strongly emarginate in circular arc ; base broadly, 

 feebly arcuate in the middle, very slightly sinuate laterally, the basal angles 

 not projecting as far behind as the median lobe ; sides evenly and distinctly 

 arcuate ; disk rather coarsely and deeply, somewhat unevenly and sparsely 

 punctate, the punctures denser toward the sides, but not contiguous. Scutel- 

 lum broadly triangular, polished, almost completely impunctate and glabrous. 

 Elytra in the middle slightly wider than the prothorax, rather more than three 

 times as long ; sides evenly arcuate ; disk with unimpressed rows of rather 

 small but deep, perforate and very distinct punctures which are circular and 

 closely placed ; intervals wide, fiat, equally punctate and pubescent through- 

 out the width, the punctures very fine and sparse, the interspaces strongly 

 shining, not; distinctly rugulose. Abdomen somewhat coarsely and sparsely 

 punctate, the pubescence moderate in length, coarse, pale and distinct. Legs 

 long. 



lilale. — Anterior tarsi extremely feebly but noticeably dilated, and having 

 beneath a narrow line of coarse flavate squamules ; intermediate robust, the 

 second and third joints each with an extremely narrow tuft of squamules 

 beneath ; abdomen with a very small area near the base which is just visibly 

 flattened. 



Length 5.7-6.5 mm. ; width 2.9-3.4 mm. 



Texas (El Paso). 



I took a single representative of this species at the indicated 

 locality, and subsequently received a large series collected there by 

 Mr. Dunn. Fimbriafus is somewhat allied to obliquus but differs 

 in its smaller size, shorter and more transverse head and prothorax 

 with less oblique sides of the latter, rather larger eyes, shorter and 

 coarser vestiture, unimpressed and more finely punctured elytral 

 strife and flat intervals. The surface also seems to be more highly 

 polished. The elytral striae become feebly impressed toward the 

 sides, but the intervals remain flat.
