similar, the third impression with a very few subobsolete coarse 

 punctures. Length 2.9 mm.; width 0.8 mm. California (Giant Forest, 

 Tulare Co.), — Chas. Fuchs flssilis n. sp. 



4 — General form, coloration and structure as !n the two preceding species, 

 the head similar in form and in its sparse punctulation but with the 

 transverse frontal impression deeper and more conspicuous, the an- 

 tennae barely as stout and scarcely extending beyond the middle of the 

 elytra; prothoraz much smaller, longer than wide, the sides more 

 broadly rounded than in laevitiscula and scarcely prominent, thence 

 moderately converging and straight to the base, widest at apical two- 

 fifths; sulcus very deep and wide» also broadening toward base, where 

 it includes the entire transverse impression, the punctulation sparse 

 throughout but untisually coarse, the punctures feebly impre<«8ed; 

 elytra nearly twice as wide as the prothorax and two- fifths longer, the 

 sides strongly diverging from base to apex, the punctulation as in the 

 preceding species; abdomen fully as wide as the elytra, finely, sparsely 

 punctulate, more asperate toward tip than usual, the impressions simi- 

 larly subimpunctate. Length 2.5 mm. ; width 0.7 mm. California (Sta. 

 Cruz Mts.) impressifrons n. sp. 



6 — Body stout in form, convex, polished as U8ual,Irather pale piceo-rufoas, 

 the head and most of the abdomen slightly darker, the legs and anten- 

 nae pale testaceous, the latter very slightly infuscate distally; head 

 as long as wide but rather fuller at the sides of the base than in laevius- 

 cula, equally minutely, sparsely punctulate, the frontal impression 

 very feeble ; antennae nearly similar In form ; prothorax but little longer 

 than wide, slightly narrower than the head, the sides subangnlarly 

 prominent attwo-flfths from the apex, thence rather strongly converg- 

 ing and straight to the base, the surface very finely, sparsely and incon- 

 spicuously punctulate throughout, the transverse subbasal impression 

 short but deep ; elytra similar inform and sculpture to laeviuscula, four- 

 fifths wider than the prothorax; abdomen similar In form and punctu- 

 lation, the first impression with rather numerous coarser punctures, 

 the second and third subimpunctate. Length 2.8 mm; width 0.8 mm. 

 California (Sta. Cruz and Monterey Cos.) robnsta n. sp. 



Body stout, smaller and rather less stout than in robusta but of the same 

 coloration and sculpture ; bead nearly similar, the antennae more slender, 

 with the third joint evidently shorter than the second ; prothorax nearly 

 similar but smaller, narrower, not quite as wide as the head, rather less 

 prominently rounded at the sides and Widest at a point rather more 

 apical, the impression more evidently broadening and deepening toward 

 base, before which there Is scarcely any transverse impression; elytra 

 slightly narrower and less transverse, similarly sculptured, the abdo- 

 men nearly similar, equally sparsely but rather less distinctly punctu- 

 late. Length 2.3 mm; width 0.68 mm. California (Los Angeles Co.). 



minnscnla n. sp. 



Body more elongate and less stout than In robusta and differing somewhat in 

 coloration^ paler rufous, the head darker, the elytra, except toward 

 base and the apical part of the abdomen blackish ; legs and antennae 

 pale testaceous, the latter slightly Infumate toward tip; vestUure 

 similarly inconspicuous ; head smaller than In robusta and more evenly,
