3i 8 MEMOIRS ON THE COLEOPTERA 



prothorax is less transverse than usual. In the female of multi- 

 fasciatus the eyes are separated by one-half more than their width, 

 the punctures of the front being coarse deep and much closer than 

 in either lucamis or the female example above identified very 

 doubtfully as puncticollis. 



Stenaspis Serv. 



The following species are allied respectively to solitaria and 

 verticalis, but differ in each instance in structural characters that 

 cannot be overlooked : 



Stenaspis lugubris n. sp. Body similar to solitaria in the uniform deep 

 black coloration, sculpture and lustre throughout, but smaller in size 

 and more parallel in form; antennae (cf ) shorter, not more than a third 

 longer than the body, the fourth joint but little shorter than the fifth, the 

 last but feebly arcuate; head much smaller in size; prothorax similar, 

 except that the lateral tubercles are less prominent and more obtuse; 

 elytra shorter and only feebly narrowed from the base, the apex more 

 broadly rounded; punctures of the sharply defined transverse prosternal 

 patches in the male small and well separated, the patches widely sepa- 

 rated, the intermediate surface simply coarsely and sparsely punctate, 

 not impressed; legs shorter and more slender, without the feeble bluish 

 reflection of solitaria; hind femora with a medial series of about three 

 coarse fovese on the outer face. Length (cf) 23.0-26.0 mm. ; width 7.0- 

 7.7 mm. Arizona (Sta. Rita Mts. and other points in the southern part 

 of the State). 



In solitaria the size is much larger and the form stouter, the 

 elytra in the male longer and more rapidly narrowed from base to 

 the relatively narrower apex, the antennae longer, w r ith the fourth 

 joint more distinctly shorter than the fifth and the last joint very 

 strongly curved and with relatively longer appendage, the legs long 

 and stout, the hind femora simply evenly and sparsely punctate 

 on the outer face and without trace of the series of foveas; finally, 

 the anterior coxae are almost twice as widely separated and the 

 sharply defined punctured spaces of the male prosternum are more 

 closely punctate and very much less widely separated, the inter- 

 mediate surface with a large, circular and shallow foveiform pit. 



Stenaspis arizonicus n. sp. Form, dorsal coloration and lustre through- 

 out as in verticalis but a little narrower; head and prothorax similar in 

 almost every way, but with the antennae (cf ) shorter, slender, the joints, 

 especially outwardly, very much less elongate, the last shorter and less 

 slender; elytra nearly similar in general form but with the punctures finer 

 and very much denser, transversely coalescent, producing a vermiculately
