Cape San Lucas, Lower California; collected by Mr. Xifltns. 

 Of the same form, size, and sculpture as P. rotundata : were it 

 not for the difference in the sculpture of the middle and hind 

 femora I should have regarded it as a black variety of that species : 

 the femora are strongly but sparsely punctured in P. rotundata, 

 while in P. pilifera they are so large as to become fovea; ; the 

 marginal hairs are also longer and more numerous. 



The species in my collection may be distinguished as follows: — 



A. Oval, finely punctulate species ; antenna? with the outer joints trans- 



verse ; 

 * Base of thorax finely margined ; 



Elytra not wider than base of thorax ; 



Margin of thorax and elytra with long hairs ; 

 Black, legs piceous, femora rudely punctured. imi.iif.ra. 



Testaceous, sometimes black beneath, femora sparsely punctured. 



BOTT.NDATA. 



Margin without hairs ; color variable ; 



Sides of thorax converging from the base. TB8TACBA. 



Sides of thorax parallel behind the middle LOBODLA. 



Elytra wider than base of thorax ; color black P1CIPBS. 



** Base of thorax not margined. DBBIUB. 



B. Small, rounded, strongly punctured species; antenna with the outer 



joints not transverse ; 

 Convex, testaceous, with black elytral spots. QL0B08A.
