1919] Calif ornian Species of Malthodes 37 



Malthodes mitificus sp. nov. 



Fuscotcstaceous, thorax yellow. Antennae longer than the body 

 in the male, entirely fuscous, joints two to four distinctly increasing in 

 length, intermediate joints about four times as long as wide. Head (cf) 

 conspicuously wider than the thorax; eyes large and prominent, sep- 

 arated anteriorly by a distance not much greater than their own diam- 

 eter. Prothorax moderately transverse, sides parallel, narrowly mar- 

 gined, front angles slightly thickened but scarcely more prominent; 

 surface shining, minutely sparsely punctulate. Length about 3 mm. 



Abdominal sexual characters. Male: sixth ventral deeply emar- 

 ginate, seventh broad, extending beyond the sixth by about the length 

 of the latter, gradually narrowed apically, the tip broadly notched; last 

 dorsal segment not produced. 



California. Mokelumne Hill. 5d^, sent by Dr. Blaisdell. 

 This species should be easily recognizable by the tabular 

 characters. The ventral sexual structure is nearly as in basalts. 



Malthodes piceolus sp. nov. 



Piceous, elytra, body beneath and legs, more or less piceotestaceous 

 as usual. Prothorax entirely piceous except for paler basal and apical 

 edge; mouth yellowish in some examples, not so in others. Antennae 

 entirely dark, fully as long as the entire body in the male, in which sex 

 joints two to four are evidently increasing in length, and the inter- 

 mediate joints fully four times as long as wide. Head a little wider 

 than the prothorax in the male, eyes not very large, separated ante- 

 riorly by rather more than twice their own width as viewed froin the 

 front. Prothorax only moderately transverse, sides parallel or slightly 

 convergent behind, margin narrow, slightly thickened at the front 

 angles, surface moderately shining and very finely punctate. Length 

 (head deflexed) 2 min. to tip of elytra. 



Abdominal sexual characters. Male: sixth ventral deeply emarginate, 

 seventh broad, nearly parallel, passing the apex of the sixth by a dis- 

 tance rather less than the length of the latter, -tip broadly not deeply 

 emarginate, a little deflexed at its extremity as seen in profile. 



California. Green Point, Humboldt Co., June 4-7 (Blais- 

 dell). The type is a male. 



Malthodes mollis sp. nov. 



Fuscotcstaceous, head blackish, thorax rufotestaceous, frequently 

 with a more or less evident diffuse darker discal shade. Antennas about 

 as long as the body in the male, entirely piceous, second and third joints 

 subequal, the fourth slightly longer; intermediate joints three to three 

 and one-half times as long as wide. Head a little wider than the thorax 

 in the male, the eyes not very prominent. Thorax moderately trans- 

 verse, sides parallel, margin fine, not appreciably thickened at the 

 front angles. Length about 23/^ mm. to the tips of the elytra.
