COLEOPTERA OF BAJA CALIFORNIA.

Asida flaccida n. sp. 



Slender, elongate, dark, castaneous, feebly 

 shining, surface with sparse, short, fulvous | 

 hairs, elytra with short, scattered, erect black 

 setas. Head very coarsely and roughly punc- 

 tured, neck more finely and densely. Thorax '£y 

 slightly wider than long, apex deeply emar- 

 ginate, sides rather strongly arcuate, very w$, 

 slightly sinuate posteriorly, base feebly bi- 

 sinuate, hind angles rectangular, disc flat at 

 middle, the sides widely reflexed, surface 

 coarsely punctate at the sides. Elytra scarcely wider 

 than the thorax and about three times as long, disc rather 

 flat, rapidly declivous posteriorly, the side margin acute, 

 not widely reflexed, terminating at the declivity in a lobe- 

 like process, surface sparsely and indistinctly punctate, a 

 fulvous hair or short spine arising from each puncture ; 

 deflexed sides of elytra sparsely spiculose. Body be- 

 neath sparsely punctate and with very short erect spin- 

 ules. Prosternum concave between the coxae. Legs 

 slender, clothed with short hairs, the outer apical angle of 

 front tibiae slightly prolonged. Length .54 inch.; 13.5 

 mm. 



It is barely possible that this species may be the male 

 of embaphionides (Proc. Cal. Acad. Sci., 1894, P- 4 I 9' P^ 

 vii, fig. 8), which it resembles in many of the minor de- 

 tails. It is, however, more slender, the sides of the elytra 

 more reflexed, and the margin developed into a lobelike 

 process at the declivity. 



One specimen. San Jose del Cabo. 



Negalius marmoratus Casey. 



The unexpected occurrence of this insect in the pen- 

 insula enables me to speak definitely concerning it.
