Malthodes reflexus sp. nov. 



Piceous, prothorax not paler. AntenriEe piceous, basal joint not 

 appreciably paler, about reaching the elytral tips in the male, a little 

 shorter in the female, joints 2-4 subequal, the third scarcely or barely 

 as long as the second, the fourth only slightly if at all longer than the 

 second, intermediate joints two and one-half times as long as wide in 

 the male, twice as long as wide in the female. Head subequal in width 

 to the thorax in the male, obviously narrower than the thorax in the 

 female; eyes not very prominent, the width of the front between them 

 fully three times that of the eye. Prothorax quite strongly transverse, 

 sides slightly convergent from the anterior angles to the base, the 

 margins more strongly refiexed than usual; disk biimpressed at middle, 

 surface distinctly, moderately closely punctate. Elytra normal in the 

 male, in the female much shorter, less than twice as long as wide, the 

 wings entirely wanting, and the abdomen projecting beyond the elytra 

 a distance as great as the elytral length. Length about 2 mm. 



Abdominal sexual characters. The seventh ventral of the male 

 is not produced, the genital appendages are similar in type to those 

 of laticollis, the lateral processes broader basally, rapidly narrowing to 

 the acuminate tip, which is slightly curved or everted, central piece not 

 keeled beneath, but angularly prominent at tip superiorly, the fila- 

 mentous process inferior in position; last ventral of female acutely 

 rather deeply incised.

Specific localities are: Marin Co. (type cf); Fairfax, Marin 

 Co., V-7-11; Vine Hill, Contra Costa Co., VI-7-08; Niles 

 Canon, V-16 (W. M. Giffard). 



Very easily recognizable by the entirely piceous color, 

 broad distinctly punctate thorax with entire side margin 

 refiexed, simple, non-produced seventh ventral of male, and 

 apterous female. 



Malthodes laticollis Lee. 



Piceous or piceo-testaceous, head darker, thorax yellow with the 

 front angles more or less infuscate. Antennae fuscous, basal joint paler, 

 as long as the body in the male, second and third joints equal, fourth 

 just visibly longer, intermediate joints about three times as long as 

 wide. Head slightly wider than the thorax in the male, eyes mod- 

 erately large, their longest diameter not much less than the minimum 

 width of the front between them; head in the female a little narrower 

 than the thorax, the eyes notably smaller. Thorax strongly transverse, 

 a little more so in the female as usual, widest at the front angles, which 

 are refiexo-incrassate, sides nearly straight and parallel posteriorly, the 

 margin distinctly refiexed throughout; surface evidently but finely
