Ell. ]>lliictiilatlini Lee. — New Spec. Col., 1866, p. 105. — Oblong-oval, 

 rather depressed, dark rufo-ferruginous throughout ; integuments thin, rather 

 smooth but very dull ; ■vvings well developed. Head strongly transverse, nar- 

 rowed from base to apex, finely, very densely punctate, truncate at apex and 

 with two small distant emarginations ; eyes rather large and distinctly more 

 prominent than the sides before them ; antennae slender, slightly longer in the 

 male, the second joint elongate, scarcely more than one-half as long as the 

 third and much shorter than the fourth, second joint in the female fully three- 

 fourths as long as the third and very nearly as long as the fourth. P)-othorax 

 from four to five-fifths wider than long, the apex distinctly narrower than the 

 base^ feebly but distinctly emarginate in circular ai'C, the angles obtuse but 

 not rounded and subprominent ; base transverse, very feebly bisinuate in the 

 middle ; basal angles very obtuse but not distinctly blunt ; sides strongly 

 arcuate in the middle, feebly convergent and very feebly arcuate thence to the 

 base, more strongly convergent and straight or very broadly sinuate in apical 

 third ; disk distinctly wider in the middle than at base, finely, rather feebly, 

 submuricately and very densely punctate throughout, with a very narrow and 

 imperfect median imijunctate line, the punctures slightly coarser laterally. 

 Eli/ira from one-fifth to one-third wider than the prothorax and four times as 

 long, distinctly wider at base than the thoracic base, the humeri exposed, 

 narrowly rounded ; sides parallel and nearly straight ; disk very finely, feebly, 

 submuricately punctate, the punctures with extremely feebly defined serial 

 arrangement. Abdomen excessively minutely, sparsely punctate ; metaster- 

 num more coarsely punctate, between coxa and groove nearly one-half longer 

 than the first ventral segment. Legs long and slender. Length 6.4-7.5 mm.; 

 width 3.0—3.2 mm. 



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



In its distinct male sexual characters this species, so far as known, 

 stands alone ; the male is lar<ier than the female, more parallel, with 

 longer antennae, and has the apex of the fourth ventral .segment 

 produced in the middle in a small feebly reflexed strongly rounded 

 lobe, extending- slightly over the fifth. Although the elytra have 

 but slight traces of serial punctuation, the series are often indicated 

 .as broad dark streaks, due to the interference of light and the coarse 

 cellular structure of the inferior surface. Superficially, ininctxdatum 

 may be readily known l)y its very dull lustre and extremely dense, 

 almost even, pronotal punctuation. 



Ell. Ilistricilin n. sp. — Oblong, parallel, rather strongly convex, piceo- 

 castaneous, slightly paler and more rufous beneath; integuments distinctly 

 alutaceous. Head short and very transverse, narrowed from base to apex, 

 finely, not very densely punctate, extremely densely so on the epistoma ; 

 apex truncate, the lateral emarginations very feeble, the lateral oblique 

 sutures however distinctly impressed ; eyes moderate, rather prominent, the 

 superior fold very strongly arcuate and almost attaining the lateral margin ;
