 breviore, lateribus antice fortiter rotundatis, basi tenuiter marginnta 

 utrinque puncto impresso ; elytris thoracis basi baud, latioribus, striis 

 obsolete punctatis, postice paulo profundioribus ; subtus prosterno, pro- 

 thoracis margine, epipleurisque louge parce pilosis, pilis flavis e granulis 

 oreuntibus ; antennis pedibusque piceis vel obscure testaceis, femoribus 

 posterioribus rude foveatim punctatis. Long. *23 '28. 



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

 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 ; antennae 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. PILIFERA. 



Testaceous, sometimes black beneath, femora sparsely punctured. 



BOTUNDATA. 



Margin without hairs ; color variable ; 



Sides of thorax converging from the base. TESTACEA. 



Sides of thorax parallel behind the middle LONGULA. 



Elytra wider than base of thorax ; color black PICIPES. 



** Base of thorax not margined. DEBILIS. 



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



joints not transverse ; 



Convex, testaceous, with black elytral spots. OLOBOSA. 



Less convex, black, with red humeral spots. HUMERALIS. 



4O3. P. longllla. Elliptica, elongata, picea, vel nigra, thorace parce 

 punctulato, antrorsum angustato, lateribus antice rotundatis postice fere 

 parallelis, basi tenuiter marginata utrinque striola parva impressa ;
