DERMORHYTIS. 377 



more remotely punctured, elytral rugosities stronger and partly 

 tuberculate. 



666. Dermorhytis costata, sp. n. 



Narrowly elongate ; fulvous ; knees, tibia? and tarsi black. 



Head very closely aud rather finely punctured ; clypeus not 

 separated from the face, a smooth space at the base of the antennae; 

 antenna? elongate, filiform, third and fourth joints equal, the 

 following joints more elongate. Thorax transversely subquadrate, 

 sides obsoletely angulate before the middle, with narrow reflexed 

 margin, surface strongly and closely punctured. Elytra with 

 double rows of closely placed deep punctures, interstices strongly 

 longitudinally costate. Femora fulvous, their apices as well as 

 the tibiae and tarsi black, the last joint of the latter more or less 

 fulvous. 



Length 5 mm. 



Hab. Burma: Karen Hills (Coll. Brit. Mus.\ 



Of totally different coloration and sculpturing from the other 

 species of the genus but possessing all its structural characters. 



C. Thorax and elytra pubescent. 



607. Dermorhytis hirsutus, Jac. (Chrysochus) Mem. Soc. Ent. Bely. 

 vii, 1900, p. 117. 



Dark violaceous-blue, clothed with short silvery pubescence ; the 

 antennae black. 



Head closely and irregularly punctured, greeuish, finely 

 pubescent ; the clypeus not separated from the face, punc- 

 tured like the head, its anterior margin moderately concave ; 

 labrum piceous ; antennae black, extending nearly to the middle of 

 the elytra, the terminal six joints dilated. Thorax about half as 

 broad again as long, the sides nearly straight, slightly rounded at the 

 middle, the surface convex, closely rugose-punctate, the interstices 

 sparingly clothed with very short silvery hairs. Scutellum with a 

 depression. Elytra wider at the base than the thorax, depressed 

 below the base near the suture, much more strongly but less closely 

 punctured than the thorax, the punctures round and deep, with a 

 very short white hair in each puncture. The underside and the 

 legs likewise covered with short pubescence ; claws appendiculate. 

 Prosternum and mesosternum elongate, narrowed between the 

 coxae ; anterior margin of thoracic episternum concave. 



Length 9 mm. 



Hab. Burma. 



This species 1 find on close examination is a Dermorhytis and 

 not a Chrysochus. From most species of Dermorhytis it is dis- 

 tinguished by the pubescence on the upper surface. This species 

 is an aberrant one and seems transitionary between the Iphimeini 

 and Colaspini.
