324 Mr. F. P. Pascoe on some new or little-known 



stiff greyish hairs; antennae not extending beyond the eyes, pale 

 yellow, strongly serrated, broadest in the middle ; eyes dark brown, 

 shining ; prothorax light pitchy brown, darker on the disk ; scutellum 

 rather large, triangular ; elytra about twice the length of the head and 

 body together, depressed, and almost concave posteriorly, with elevated 

 nervures in the middle, i. c. not extending to the base or apex ; legs 

 clothed with stiff hairs, particularly on the tibiae ; abdomen dull 

 whitish yellow. Length 4 lines. 



In the Plate the figure of this species is longer than it ought to be. 



Ethas [Tenebrionidae]. 

 Head elongate, broader than the prothorax, rounded and dilated anteriorly, 

 narrowed into a neck behind. Eyes remote from the prothorax, lateral, 

 partially divided posteriorly. Mentum somewhat pentagonal, narrow 

 at the base, concealing the labium. Maxillary palpi robust, the ter- 

 minal joint subcylindric, of the labial ovular. Antennae stout, eleven- 

 jointed, the first largest, the second shorter than the third, which, with 

 the remainder to the tenth inclusive, are transverse and cup-shaped, the 

 eleventh small, shortly cylindric. Prothorax sulcated, subquadrangular, 

 broadest in front, the anterior angles rounded, the sides keeled. Elytra 

 elongate-ovate, wider than the prothorax, ribbed. Legs robust ; femora 

 slightly clavate ; tibiae not spurred ; tarsi ciliated beneath ; presternum 

 produced, rounded anteriorly. 



The ribbed prothorax and elytra will at once distinguish this genus 

 from Stenosis, which has exactly the same habit. The structure of 

 the mouth varies a little from that genus, in Ethas the large angular 

 mentum filling up more of the oral cavity, and entirely concealing 

 the labium. 



Ethas carbonarius. (PI. XVI. fig. 2.) 

 E. niger, subnitidus ; prothorace leviter trisulcato ; elytris singulis lineis 



quinque elevatis instructis. 

 Hub. Malabar. 



Punctured, black, slightly shining ; head convex between the eyes, 

 with three rather shallow grooves, and on each side a somewhat deeper 

 groove in which the eye is placed ; prothorax a little narrower than the 

 head, marked with three lightly impressed lines or grooves, the spaces 

 between, especially the two middle, slightly elevated and convex ; scu- 

 tellum punctiform ; elytra scarcely wider than the prothorax at its 

 base, each with five narrow elevated lines rather thickened at the 

 suture, but scarcely forming another ; legs slightly pitchy ; palpi ferru- 

 ginous ; body beneath black, shining, sparingly punctured. Length 4 

 lines. 



Ethas stenosides. 

 E. niger, subnitidus ; prothorace profunde trisulcato ; elytris singulis 



lineis quatuor elevatis instructis. 

 Hab. Siam.
