350. Cryptocephalus rufofemoratus, sp. n. 



Dark fulvous ; antennae (basal joints excepted) black ; thorax 

 with two black bands, connected at base, or with two spots at 

 middle ; elytra flavous, a small humeral spot and a transverse 

 band (or spot) near apex black ; femora fulvous ; tibiae and tarsi 

 black.

 tures near eyes ; clypeus subtriangular, distinctly separated from 

 face at sides, rugosely punctured ; eyes not very deeply emarginate ; 

 antennae long and slender, the first or the basal three joints 

 fulvous, rest black, third joint shorter than fourth. Thorax 

 moderately convex, sides very narrowly margined, feebly rounded, 

 posterior angles not produced, surface entirely impunctate. Scu-

In one specimen before me the head is deeply longitudinally 

 sulcate at middle, the elytral band is reduced to a large spot, the 

 extreme sutural and lateral margins at apex and the abdomen are 

 black and the thorax has two spots placed at middle ; in other 

 respects the specimen is typical. 



351. Cryptocephalus semiflavus, sp. n. 



Black ; head with a large triangular flavous patch ; elytra 

 yellowish-white, a transverse large spot at basal margin and a 

 transverse broad band near apex black. 



Vertex of head black, the entire middle portion and clypeus 

 flavous, the latter rather depressed with some fine punctures but 

 not separated from face ; labrum piceous ; antennae black, basal 

 two joints flavous at apex, third and fourth joints equal, slender. 

 Thorax subcylindrical, sides strongly deflexed, lateral margins feebly 

 rounded, narrowed in front, posterior margin distinctly serrate ; 

 surface impunctate, very shining. Scutellum broad, triangular, 

 black. Elytra feebly lobed at sides, distinctly punctate-striate, the 

 basal patch widened at middle, not extending quite to either 

 margin, the posterior band curved and narrowed near lateral 

 margins, extending across both elytra. Prosternum subquadrate, 

 finely punctured, posterior angles pointed, anterior margin not 

 produced ; anterior edge of metasternum flavous. Tarsi with very
