the Ininieri obtusely rounded, umhone distinct, with a sligiit impression within 

 it, sides parallel, disc convex, the punctuation less coarse than that of the thorax, 

 very irregularly placed, but in some specimens showing the tendency to irregular 

 strise. Body beneath piceous, slightly bronzed. Abdomen punctate, the first 

 (and last 9) segment sparsely, the others more closely, surface sparsely pubes- 

 cent. Legs pale brown to rufotestaceous, the posterior femora usually darker. 

 Length .12— .14 inch. ; 3—3.5 mm Plate VII, fig. 2. 



Ill tlie male the last ventral segment is slightly sinuate each side, 

 the middle lobe broadly, but feebly concave. The first joint of the 

 anterior tarsus is broader than in the female. The antennje are also 

 longer and more slender. The last ventral segment is also more 

 closely punctate. 



In the female there is sometimes a transverse impression of the 

 last segment near the apex. 



This species does not show much variation. The elytra! sculpture 

 is faintly striate, but usually nuich confused and irx-egular. It is 

 very rarely slightly bluish or greenish in color. 



As specimens are usually .seen in the cabinet the upper surface is 

 glabrous, but in well preserved examples the surface is sparsely 

 clothed with nearly erect short hairs arising from the ])unctures, 

 usually evident near the sides of the thorax and elytra. There are 

 a few also near the sides of the head. 



Occurs in California, especially in the lower portion of the State. 



CREPIDODERA Chev. 



Front more or less triangular, inserted as far as the eyes, frontal 

 carina more or less distinct, the tubercles often feeble. Eyes round, 

 convex. Antennae as long as half the body, gradually slightly 

 broader to tip, first joint oblong oval, secfmd half as long, 3-10 sub- 

 equal, a little longer than second, eleventh longer, acute at tip. 

 Maxillary palpi short, the fourth joint conical, as long as or a little 

 longer than the preceding. Thorax broader than long, an ante-basal 

 impressed line variable in depth, limited at each end by a longitudinal 

 impression. Prosteruum distinctly separating the coxi^e, dilated 

 behind tliem and with the epimera closing the coxal cavities. Me- 

 sosternum usually distinct, the middle coxse either moderately or 

 rather widely separated. Metasternum oval or acute in front, and 

 in robiisfa prolonged over the mesosternum. First ventral segment 

 as long as the next three, which are nearly equal in length, fifth a 

 little longer. Legs moderate, the tibite rounded on the outer face, 

 the posterior tibiae obliquely truncate and with a small spur.
