species is related to gemina and nebtilosa, and is remark- 

 able in having the vestiture of the under side scale-like 

 and not hairy. 



One specimen found on cactus, San Raymundo. 



ACM.^ODERA DELUMBIS n. Sp. 



Closely resembling gibb II I a in form and coloration, dif- 

 fering as follows : Thorax more coarsely and closely 

 punctate. Elytra with a row of five yellow spots on each 

 side, centering on the fourth interval, a row of three spots 

 on the ninth or widest interval also yellow, red in gibbiila, 

 a marginal row of four yellow spots. Prosternum as 

 in gibbula. Metasternum at sides coarsely and moder- 

 ately closely punctate, sparsely hair3^ Abdomen rather 

 finel}^ punctate not much more closely at sides than at 

 middle, the pubescence at sides sparse and not conspicu- 

 ous. Last ventral as in gibbula. Length, .47 inch; 12 

 mm. 



The most conspicuous differences are that in this spe- 

 cies the sides of the abdomen are not conspicuously pu- 

 bescent and the sides of the elytra have the spots yellow 

 and not red. The last named character may not be per- 

 manent, the first is valid and not sexual. 



Two specimens from Arizona; others in the National 

 Museum at Washington. 



Agrilus ineptus n. sp. 



Similar in form to acittipennis or ■pnlcheJhis, bluish

 space between the antennas at base. Thorax a little 

 wider than long, slightly narrower at apex, sides feebly 

 arcuate, hind angles obtusely carinate, a moderate median 

 impressed line, at sides an oblique depression, surface 

 with rather coarse transversely undulating strigae. Scutel-
