108 CEBAMBYCID^E. 



squarely turned in towards the apex, each with a dorsal ridge 

 along the straight portion ; palpi subequal ; gula with outmenti- 

 gerous process. Antennae longer than the body; first joint stout, 

 thickened towards the apex and reaching almost to the middle 

 of the prothorax ; third much longer than the first, fourth to 

 eleventh gradually shorter and more slender. Prothorax trans- 

 verse, somewhat variable in form, strongly rounded at the 

 sides and feebly tuberculate behind the middle in the d of the 

 type species ; a little rounded and strongly tuberculate at the 

 middle of each side, with a sulcate constriction near the base and 

 apex, in the second known species. Elytra broader than the pro- 

 thorax, more than twice as long as broad, gradually narrowed 

 backwards, the sides more strongly convergent at the apex. 

 Legs moderately long ; the femora stout, subfusiform ; first joint 

 of hind tarsus not so long as the next two united. Front coxae 

 transverse, their acetabula open posteriorly ; intercoxal process 

 distinct but rather narrow, parallel-sided. Intercoxal process of 

 mesosternum triangular, concavely depressed along the middle. 

 Episterna of metathorax broad in front, gradually narrowed 

 almost to a point posteriorly. Stridulatory area of mesouotum 

 with an impressed line along the middle. First cubital vein of 

 wings bifurcate posteriorly, second cubital wanting.

pi. 3, fig. 7 (1853). 



3 . Cinnamon-brown ; elytra with dark brown lateral margins, 

 marked each with two black-brown spots placed obliquely 

 between the base and the middle, with another large oblique 

 spot or baud a little beyond the middle. Head densely rugulose- 

 punctate. Antennae extended by about tw y o or three joints past 

 tlie apex of the elytra ; first joint very stout, densely granulate, 

 third to sixth armed posteriorly at irregular intervals with short 

 spines, third nearly twice as long as the first. Prothorax large, 

 transverse, nearly as wide as the elytra, a little depressed above, 

 strongly rounded at the sides but drawn in at the base and 

 furnished behind the middle with a feeble tubercle ; the surface 

 densely rugulose-punctate, sparsely covered with rather long 

 pubescence. Shape of the elytra as in the figure of the next 

 species. The intercoxal process of the prosternum is gradually 

 sloped in front.

102. Oplatocera oberthuri, sp. n. 



Cinnamon-brown; antennae tipped with dark brown at the 

 apex of each joint; prothorax with two black-brown spots on the 

 disc and a narrow dark band towards each side ; elytra marked 

 each with two oblique black-brown bands that appear to be
