hair. Elytra regularly oval, broadest at middle, one-half 

 longer than wide, base not wider than base of thorax, disc 

 convex with the striae of coarse punctures not closely 

 placed, intervals slightly convex and with two series of 

 finer punctures irregularly placed each bearing a short 

 yellow hair. Body beneath more shining than above, 

 coarsely but not closely punctate. Length, .22 inch; 

 5.5 mm. 



Similar in form to perforatus, but with the striae of the 

 elytra more closely and the thorax more densely punc- 

 tured. The finer punctures of the intervals \n perforatus 

 are scarcely evident and the hairs very short. 



One specimen. Miraflores. 



Cerenopus angustatus Horn. Proc. Cal. Acad. Sci. 

 1894, p. 426. 



A recent invoice with a dozen specimens shows that 

 my description of the female was erroneous. The female 

 at hand was merely a feeble specimen of concolor. 



The female of angustatus has the clypeus very differ- 

 ent from the male, which may be described as truncate 

 with an abrupt median notch either oval or subtriangular. 

 In the female there is a deep sinuation each side of the 

 notch and the angles are obtusely produced so that the 

 front has somewhat a quadridentate appearance. The 

 posterior femora have on the inner side of the lower edge 

 a series of well marked tubercles. PI. xx, figs. 4, 5. 



In addition to the locality at San Jose del Cabo it also 

 occurs at Pescadero, Santo Domingo del Taste, Sierra 

 El Chinche, San Lazaro and Miraflores. 



Macrobasis languida n. sp. 



Form slender, general color pale luteous clothed with 

 slightly paler pubescence, antennse and tarsi black. Tho- 

 rax longer than wide, a feebly impressed median line.
