Ell. COllvexicolle Lee. — Ann. Lye. N. Y., V, p. 139.— Oblong-oval, 

 strongly convex, piceous-black, sometimes paler, shining. Head moderately 

 transverse, coarsely, deeply, perforately punctate, the punctures rather dense 

 hut not contiguous ; apex truncate, entire ; eyes moderate, very slightly more 

 prominent than the sides before them, the superior folds advancing well beyond 

 them and strongly arcuate ; antennae rather slender, the third joint fully 

 three times as long as wide and much longer than the fourth. Prothorax from 

 four, to nearly five-fifths wider than long, the apex about five-sixths as wide 

 as the base, very feebly emarginate, the angles right and not blunt ; base 

 transversely truncate, broadly, very feebly sinuate at each side of the middle, 

 the basal angles broadly obtuse but not at all rounded ; sides distinctly arcuate, 

 more convergent and straighter toward apex ; disk coarsely, deeply punctured 

 throughout, the punctures toward the sides gradually very closely crowded 

 and longitudinally confluent, but not much larger than those toward the 

 middle where they are usually separated by from once to twice their own 

 diameters. Elytra usually very slightly wider than the prothorax and rather 

 more than three times as long, generally about one-half longer than wide ; 

 sides very feebly arcuate ; apex obtusely ogival ; disk rather finely, sparsely 

 and irregularly punctate toward the suture, but much more coarsely and 

 asperately so laterally where the punctures are arranged in approximate 

 series, especially coarse and dense toward the humeri. Abdomen finely, 

 sparsely punctured; metasternum from coxa to impressed groove just visibly 

 shorter than the first ventral segment. Legs moderate, rather robust, the 

 posterior tarsi much shorter than the tibiae. Length 6.4-7.5 mm. ; width 

 2.8-3.3 mm. 



California (Barstow, San Bernardino and the Colorado Desert). 



The series of eleven specimens exhibits considerable variation, not 

 only in color but in general form, but is not sufficiently extensive 

 to enable me to define any distinct varieties; the species may be 

 readily known by its robust, convex form, strongly transverse and 

 densely, very coarsely punctured pronotum. The hind wings are by 

 no means obsolete, although rudimentary ; they are broad, hyaline 

 and about two-thirds as long as the elytra, the latter subconnate. 



Ell. cy lilldricuill n. sp. — Elongate, parallel, very strongly, cylindri- 

 cally convex, shining, the head very dull, black to piceous throughout. Head 

 transverse, truncate, generally finely and decidedly sparsely punctate, the 

 punctures sometimes rather coarse but always distant ; eyes moderate, the 

 fold very acute, long and feebly arcuate ; antennae rather slender, the third 

 joint but slightly more than twice as long as wide and only slightly longer 

 than the third. Prothorax from two-thirds to four-fifths wider than long, the 

 apex very feebly incurvate, the angles right and not at all blunt, the base 

 transverse, the two median sinuations very feeble ; basal angles slightly 

 obtuse, not at all rounded and frequently very slightly prominent ; sides 

 parallel aud very feebly arcuate, more convergent and straighter in apical
