Casey — A Revision of the American Paederini. 117 



Elytral punctures distinctly, though somewhat unevenly, serial in arrange- 

 ment throughout. Body similar in form and coloration to the pre- 

 ceding but smaller in size and more coarsely and closely sculptured; 

 head well developed, parallel at the sides, the angles very broadly 

 rounded to the neck ; eyes unusually small, at more than three times 

 their own length from the base ; punctures very coarse and close-set, 

 becoming somewhat sparser on the vertex; antennae less stout than 

 usual, very feebly incrassate distally, the medial joints equal in length 

 to the subapical; prothorax narrow and strongly elongate-oval, much 

 narrower than the head, coarsely and rather closely punctured; elytra 

 much elongated, parallel, two-tifths wider and a third longer than the 

 prothorax, very coarsely but not so closely punctate; abdomen slightly 

 narrower than the elytra, less finely and rather closely punctate, 

 somewhat shining. Male with a small oval glabrous pit on the median 

 line at apex of the fifth ventral, the sixth with a small shallow, broadly 

 rounded sinus at apex, the adjoining surface very feebly, triangularly 

 impressed and wit'a short black spiculiform hairs as in the preceding 

 species; female with the sixth ventral very broadly, obtusely rounded 

 at tip. Length 6.7-7.5 mm.; width 1.05 mm. California (Hoopa 

 Valley, — Humboldt Co.) glioma u. sp. 



5 — Head equal in width to the elytra. Body rather stout, parallel, convex, 



shining, pale testaceous in color throughout, the legs and antennae 

 concolorous — probably immature; head well developed, the sides 

 parallel, broadly, evenly rounded at base to the neck; eyes rather 

 small, at more than three times their own length from the base; punc- 

 tures notably coarse but well separated throughout; antennae not very 

 stout, rather short, the median joints but little longer than wide in 

 the female ; prothorax oblong, slightly longer than wide, much narrower 

 than the head, the sides parallel and straight in the middle, the angles 

 broadly rounded, the anterior much more broadly than the posterior, 

 the punctures similar to those of the head, coarse and rather widely 

 separated, the median smooth line wide; elytra quadrate, parallel, 

 barely as long as wide, equal in length to the prothorax and a third 

 wider, the punctures very coarse, not close-set, arranged in rather 

 uneven series throughout; abdomen parallel, fully as wide as the 

 elytra, rather finely but not very closely punctate, shining. Male 

 unknown; female with the sixth ventral broadly rounded at tip. 

 Length 6.0mm.; width 1.0 mm. California (Lake Co.).validiceps n. sp. 

 Head wider than the elytra; body more slender; elytra shorter than the 

 prothorax except in subseriata 6 



6 — Form moderately slender, dark rufo-piceous, the ely'ra and legs 



brighter rufous, the abdomen black, the auteunae infuscate; head oval, 

 somewhat longer than wide, parallel, the basal angles very broadly 

 rounded to the neck; eyes rather small; antennae stout, distinctly 

 incrassate distally, the medial joints about a third longer than wide, the 

 punctures coarse and deep but well separated; prothorax narrow, 

 elongate-oval, very much narrower than the head, the anterior angles 

 very broadly rounded and wholly obsolete, the punctures coarse, deep 

 and rather close-set; elytra parallel, slightly longer than wide, about a 

 fifth wider than the prothorax and equal in length to the latter, the
