femur. lu each sex the sides of the pronotum are conspicuously 

 granulate and the outer margin plainly serrate, and the prouotum is, 

 especially in the 9 , a little more ampliated laterally at about one- 

 third of the length, and more sharply acuminate at apex than in the 

 other species of the genus. The anterior and intermediate tibiae have 

 each four sharp spines underneath. The number of spines in the two 

 rows on the underside vary, being 10-8, 9-8, and 8-7. The antennae 

 from about a third of the length from the base are faintly annulate.

ARYTROPTERIS EXCISA, u. sp. 



9 . Similar to A. gramdithorax in almost all respects, save that the 

 pronotum is more emarginate laterally past the median part, and the 

 apex, instead of being acuminate, has a broad crescent-shaped emargi- 

 nation, too regular to be accidental ; moreover, the margin of the 

 emargination and that of the sides is identical; the sculpture, antennae 

 and disposition of the spines on the legs are the same as in A. granuli- 

 thorax.

ARYTROPTERIS MODESTA, n. sp. 



Greyish stramineous, speckled with numerous minute, very closely set 

 bronze macules ; the basal lateral abdominal bronze band is distinct ; 

 the anterior part of the pronotum is very little ampliated, and is some- 

 what blunt at apex, and very slightly sinuate on each side there ; the 

 antennae are distantly annulated with fuscous from the basal third of 

 the length ; the spines of the legs are somewhat long and sharp, and 

 there is only a single row of five spines under the hind femora, the 

 outer ridge being simple. In the male he elytra are somewhat 

 developed and plainly visible under the pronotum.
