Pronotum much more coarsely and sparsely punctate ; antennal club equal 

 in length to the funicle, the last joint much less, although distinctly, 

 asymmetric, slightly longer than wide ; sixth joint of funicle just visibly 

 more prominent anteriorly; fifth joint of hind tarsi distinctly longer than 

 the first two combined ; elytra at apical two-fifths fully one-fourth wider 



than the prothorax ; color pale, brown pai'Vicollis 



Sides of protliorax — viewed vertically — broadly, evenly arcuate, subaugulate 

 when viewed laterally, the surface much more convex and declivous at the 

 sides ; pronotum finely and very sparsely punctate; antennal club slightly 

 but distinctly longer than the funicle, tlie last joint wider than long ; sixth 

 joint of funicle not at all prominent anteriorly; elytra equal in width to the 

 prothorax; surface highly polished ; color deep black paciflcllS 



P. parvicollis n. sp, — Form slender, rather depressed ; sides parallel ; 

 dark reddish-brown, somewhat bronzed ; head and pronotum darker ; legs 

 throughout dark brown ; integuments polished. Head rather small, coarsely, 

 deeply and rather densely punctate ; front with several long coarse fulvous 

 setae ; mandibles small ; antennal club about equal in length to the funicle ; 

 last joint very slightly oblique, slightly longer than wide. Prothorax small, 

 widest very near the middle where it is nearly twice as wide as long, and where 

 the sides are distinctly angulate from above, the angle narrowly rounded ; 

 apex broadly, very feebly emarginate, slightly narrower than the base ; the 

 latter transversely truncate ; angles slightly prominent, acute, not at all 

 rounded ; sides nearly sti-aight anteriorly and posteriorly, rather strongly 

 convergent in botli senses, feebly sinuate near the base ; disk broadly, feebly 

 convex, rather broadly but not strongly reflexed at the sides, coarsely and 

 strongly punctate, the punctures rather sparse in the middle, with a narrow, 

 incomplete, impunctate median line, dense toward the sides, except in the 

 reflexed portion, where they are very sparse and coarser. Scutellum much 

 wider than long, parabolic, very sparsely, coarsely punctate at base. Elytra 

 at base fully as wide as the prothorax ; sides parallel, distinctly arcuate 

 behind, nearly straight and feebly divergent in the basal fourth ; together 

 evenly and rather strongly rounded behind ; disk transversely and moderately 

 convex, four-fifths longer than wide, three and one-third times as long as the 

 prothorax, widest at two-fifths the length from the apex where it is one-fourth 

 wider than the latter ; strife nearly equidistant, feebly impressed, rather finely, 

 deeply punctate, the punctures closely approximate ; intervals feebly convex, 

 sparsely creased, finely, unevenly and sparsely punctate. Legs slender ; poste- 

 rior tarsi just visibly shorter than the tibise. Length 10.3 mm. ; width 4.0 mm. 



California. 



Readily distinguished from Agassii and pacificus by the pale 

 color, small prothorax which is here much narrower than the elytra, 

 and by the great relative length of the latter. The type is a male ; 

 the antennal club being relatively very much shorter than in either 

 of the species mentioned. In Agassii the funicle is three-fifths as
