bred from Ceanothus cuneatus Nutt. that was secured from 

 Placerville. 



Type in my own collection, collected at Hullville, Lake 

 County, Cal., June 14-17, 1917, by Dr. F. E. Blaisdell, to whose 

 generosity I am indebted for the same. Paratypes are in Dr. 

 Blaisdell's collection. 



Acmaeodera wenzeli n. sp. (PI. VII, fig. 4). 



Form elongate, subparallel, slightly depressed, bronzed, elytra with a 

 bluish tinge, sparsely covered above with moderately long, erect, black 

 hair, changing to white laterally, prothorax unicolorous, each elytron 

 with three distinct yellow maculations placed as follows : One triangular 

 blotch placed halfway between base and apex and extending slightly 

 forward along margin and inwardly four intervals from the margin, a 

 second fascia between this and apex and extending from the third 

 stria obliquely outward almost to margin, the third a small spot placed 

 subapically and on the third and fourth intervals (in my specimen 

 there is also a fourth spot on right elytron between the second and 

 third maculation). 



Head moderately coarsely and sparsely punctate, no frontal carina, 

 clypeus deeply semicircularly emarginate, antennae with fifth joint 

 suddenly dilated ; thorax less than twice as wide as long, apex and 

 base subtruncate, sides rounded in front, parallel and straight for 

 posterior two thirds, margin fine, not visible from above, disc with a 

 slight median basal impression and a deeper one each side midway 

 between this and the posterior angles, the latter the terminations of 

 shallow oblique lateral impressions, the disc rather finely and sparsely 

 punctate and the sides coarsely and cribrately punctured. 



Elytra as wide at base as the thorax, umbones feebly prominent, 

 sides slightly sinuate to posterior two-thirds where elytra are widest, 

 thence gradually convergent and rounded to apex, margin slightly ser- 

 rate posteriorly, disc somewhat convex, striae finely impressed anteri- 

 orly, quite deeply posteriorly, and with rather coarse punctures basally 

 and fine apically, intervals flat and with a single series of fine punc- 

 tures. 



Body beneath coarsely, densely punctured anteriorly, finely, sparsely 

 over abdomen, clothed with long white hair, the anterior margin of 

 prosternum subtruncate, the last ventral with distinct subapical carina. 



Length 9.25 mm., breadth 3.25 mm.. 



This species belongs with the species having a truncate pro- 

 sternal margin and is close to A. consors Horn, from which it 

 diflfers by having a diflferent type of maculation as well as a 

 diverse shape, particularly in respect to the prothorax, and
