COI.EOPTERA OF BAJA CALIFORNIA. 415 



Legs coarsely closely punctate. Length from apex of 

 thorax to tip of elytra, .83 inch; 21 mm. 



While the absence of the head prevents a certain as- 

 signment of the species generically there seems to be but 

 little doubt of the correctness of the assumption that it is 

 a Centrioptera. It seems to go one step further from the 

 general form of the genus than infausta toward Crypto- 

 glossa. From all our species it differs in having the 

 hind ancles distinctlv everted and the lateral margin in 

 front of them slightly reflexed. These characters are 

 faintly indicated in some infausta. 



El Paraiso. 



ASIDA PLANATA n. Sp. 



Of the exact form of ofaca, black, subopaque. Head 

 coarsely punctate. Thorax coarsely and closely punc- 

 tate. Elytra slightly broader at base than the thorax, 

 humeri distinct, the margin at that point sHghtly reflexed, 

 disc transversely flat, the lateral marginal carina very 

 nearly reaching the apex, surface even, without costa? or 

 wrinkles, with sparsely placed small granules each bear- 

 ing a minute hair, Prothorax beneath very coarsely 

 punctured, granulate each side of the coxx. Entire 

 mesosternum and sides of metasternum granular. Ab- 

 domen finely sparsely punctate, last two segments more 

 densely. Legs closely punctate. Length, .63 inch ; 16 

 mm. 



In the unique female before me there is a small fovea 

 each side of the median line in front of the middle of 

 the disc of the thorax. This is probably individual here 

 as it is known to be in morbiUosa. 



This species may be known by its resemblance to opaca 

 in form, differing in its almost sculptureless elytra which 

 are flat in a transverse direction.
