370 A Preliminary Moiiograph of the 



vex, and prominent, very coarsely faceted ; antennae short, somewhat 

 slender, distinctly capitate, not quite as long as the head and prothorax ; 

 second joint nearly as long as the next two together, third very slightly 

 longer than wide, fourth small, quadrate, joints two to four gradually 

 decreasing in thickness, tenth very distinctly transverse. Prothorax 

 one-fourth wider than long, widest at anterior third, where the sides 

 are rather broadly rounded and coarctate to the apex, rather strongly 

 convergent and straight toward base ; the latter broadly arcuate, about 

 three-fourths as wide as the disk and much narrower than the apex; the 

 latter broadly, feebly arcuate ; apical angles distinctly rounded, basal 

 rather broadly so; disk broadly convex, without trace of impression but 

 with a rather wide, impunctate median line, which is not at all tumid ; 

 punctures minute and very dense. Elytra quadrate, about one-third wider 

 and one-half longer than the prothorax, feebly convex, rather distinctly 

 impressed near the suture, somewhat finely and densely punctate ; the 

 punctures twice as large as those of the pronotum and separated by 

 less than twice their own diameters. Abdomen distinctly narrower 

 than the elytra, parallel ; sides nearly straight ; border moderate ; sur- 

 face finely, feebly reticulate, minutely and moderately densely punc- 

 tate. Legs slender. Length 2.1 mm. 



California (San Diego 1). 



This species somewhat resembles dehilis, and without care 

 might possibly be confounded with it, especially as they are inhabi- 

 tants of the same region. It is easily distinguishable, however, 

 by its smaller eyes, much sliorter antennae, which are of a dif- 

 ferent structure, by the form of the prothorax, presence of a 

 median impunctate line, lack of impressions, and by the coarser, 

 sparser elytral punctures. The form of body is more slender. 



48 T, pauperculii§ n. sp. — Moderately robust and convex, black ; 

 legs rather pale piceous-brown ; antennae rufo-testaceous, fuscous at 

 apex ; pubescence very minute, fine, moderately dense ; integuments 

 rather §hining. Head slightly narrower than the prothorax, very 

 minutely and extremely densely punctate; prominences moderate in size,^ 

 not strong ; antennae rather short, moderately robust, slightly incrassate, 

 slightly shorter than the head and prothorax ; joints two to four de- 

 creasing very rapidly in length, the former just visibly more robust,, 

 three times as long as the latter, which is very slightly wider than long, 

 tenth strongly transverse ; eyes very large and prominent, very coarsely 

 faceted. Prothorax widest near apical third, where the sides are evenly 

 rounded, thence very feebly convergent and distinctly arcuate to the 

 apex, rather strongly convergent and nearly straight toward base ; the 

 latter evenly and distinctly arcuate, three-fourths as wide as the disk 

 aind very much narrower than the apex ; the latter broadly, feebly
