SciRTES HUMERALIS n. Sp. 



Oval, slightly oblong, piceous, moderately shining, 

 head and thorax rufescent, a reddish band along the side 

 margin from the humerus one-third to apex, each elytron 

 with an indefinite paler area at apex, surface sparsely 

 fulvo-pubescent. Antennae testaceous, gradually darker 

 to tip. Head rufescent, sparsely punctate, occipital re- 

 gion narrowly piceous. Thorax sparsely punctate. Scu- 

 tellum rufescent, piceous at middle, punctate. Elytra 

 slightly more coarsely punctate than the thorax. Body 

 beneath piceous; metapectus smooth; abdomen moder- 

 ately closely punctulate. Legs rufo-testaceous, the fem- 

 ora darker. Length, .12 inch; 3 mm. 



This species is more oblong and convex than the others 

 of our fauna. It is most nearly related to orhiculatus by 

 the presence of a distinct infra-orbital ridge. 



One specimen. San Jose del Cabo. 



Malthodes lucanus n. sp. 



Slender, piceous, thorax yellow. Antennse slender 

 longer than the body, joints two and three equal, each a
