Phyllobaenus merkeli n. sp. 



Slender, parallel, piceous black, moderately shining, 

 with sparsely placed erect hairs, and a silken white pu- 

 bescence forming an indistinct design on the elytra, each 

 elytron with a yellow spot on the margin behind the 

 middle. Head coarsely, densely punctate. Thorax 

 slightly wider than long, obtusely subangulate behind the 

 middle, disc flattened at middle, surface densely and 

 coarsely punctate. Elytra slightly wider posteriorly, 

 disc flattened with a short smooth subcostiform elevation 

 about the middle of the disc on each side, surface coarsely, 

 deeply, and closely punctate. Body beneath very sparsely 

 punctate and hairy. Length .20-. 22 inch. ; 5-5.5 mm.

 color, the punctures of the elytra are confused, and there 

 is the short costa, and finally, it differs in the vestiture 

 and markings. Southern Arizona. Merkel.
