DERMORHYTIS.

more remotely punctured, elytral rugosities stronger and partly 
tuberculate. 
666. Dermorhytis costata, sp. n. 
Narrowly elongate ; fulvous ; knees, tibiae and tarsi black. 
Head very closely and rather finely punctured ; clypeus not 
separated from the face, a smooth space at the base of the antennae; 
antennae 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. Eemora fulvous, their apices as well as 
the tibia? and tarsi black, the last joint of the latter more or less 
fulvous. 
Length 5 mm. 
Bab. Burma: Karen Hills (Coll. Brit. Mas.). 
Of totally different coloration and sculpturing from the other 
species of the genus but possessing all its structural characters. 
C. Thorax and elytra pubescent. 
667. Dermorhytis hirsutus, Jac. (Chrysochus) Mem. Soc. Eat. Bela. 
vii, 1900, p. 117. 
Dark violaceous-blue, clothed with short silvery pubescence ; the 
antennae black. 
Head closely and irregularly punctured, greenish, 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 
coxse ; anterior margin of thoracic episternam concave. 
Length 9 mm. 
Hab. Burma. 
This species I. find on close examination is a Dermorhytis and 
not a Chrysochus. Erom 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.
