California. Mokelumne Hill, April (Blaisdell), type c?" ; 

 Adams Springs, Lake Co., June 18 (Blaisdell). 



Malthodes complicatus sj^. nov. 



Fuscotestaceotis, head piceous, thorax entirely yellow or with the 

 extreme margin at apical angles infuscate. Antennae longer than the 

 body in the male, entirely fuscous, second and third joints subequal, 

 fourth evidently longer, intermediate joints more than four times as 

 long as wide. Head {d^) wider than the pro thorax, eyes moderately 

 prominent. Prothorax moderately transverse, sides parallel and nar- 

 rowly margined, margin not appreciably thickened at the front angles. 

 Length (head deflexed) 23-^ mm. to tips of elytra. 



Abdominal sexual characters. Male: last (?) dorsal with a slender 

 descending lateral process, which is abruptly bent at right angles, the 

 tenninal portion horizontal. Sixth ventral deeply, broadly emar- 

 ginate, the bottom of the emargination truncate; seventh ventral 

 received between the descending dorsal processes, elongate, narrow, 

 forked rather deeply at tip, obliquely ascending in profile in its apical 

 two-thirds. 



California. Pomona, March 25 (type cf); Pasadena; 

 Claremont (Baker); Santa Barbara, Feb. 4; Ojai Valley, 

 March 5. 



Superficially closely resembling the preceding species, but 

 very distinct by the sexual characters. 



Malthodes sericeiventris sp. nov. 



Fuscotestaceous, head piceous, thorax entirely clear yellow. 

 Antennae as long as the body in the male, entirely fuscous, joints two to 

 four visibly increasing in length, intermediate joints nearly five times as 

 long as wide. Head (male type) notably wider than the thorax, with 

 prominent eyes; less wide in a second male. Thorax moderately trans- 

 verse, sides straight and nearly parallel, side margins fine, not appre- 

 ciably thickened at the front angles. Length (head deflexed) 2}/2 mm. 



Abdominal sexual characters. Male: ventral segments 3 to 5 silvery 

 sericeous at middle throughout their length; sixth deeply emarginate; 

 seventh elongate, narrow, deeply divergently forked apically, in profile 

 obliquely ascending in about its apical half, the tips of the forks 

 thickened and concavely beveled. 



California. Pomona, April 25-May 20; 2 d^, 2 9 ; type d". 



The sericeous ventral area of the male is quite unique and has 

 the appearance of an excessively short and dense silvery pile, 

 but it is not resolvable, as such by a 3^ inch triplet, and is 

 probably due to surface sculpture.
