second female dorsal genital segment, at least at the sides, fus- 

 cous-black, venter often of a dark greenish hue and probably 

 always green in living specimens; antennae, rostrum, and legs 

 concolorous with the body, the first three antennal joints and 

 femora densely and very finely dotted with brown, apex of 

 second and third antennal joints fuscous, fourth joint whitish 

 with a greenish tint (probably pale green in the live insect), 

 tibiae with three narrow fuscous annulations, the nethermost of 

 which is sometimes obliterated. Head slightly longer than 

 broad, second joint of antennae subequal in length to first, fourth 

 half the length of third and a little narrower than the clavate 

 part of the first. Pronotum a little longer than head, lateral 

 margins almost straight, sinuate only before the humeral tooth. 

 Abdomen with the apical angles of the fifth segment a little 

 prominent, male genital segment trituberculate at apex, the 

 median tubercle larger and more prominent than the lateral 

 ones, the margin arcuately sinuate on each side between the 

 tubercles. 



Length, male, 14.5 millimeters; female, 14.8 to 16.2. 



Luzon, Laguna, Mount Maquiling and Paete. 



This species does not seem to be rare in the first-named locality. 



Genus XENOCERAEA novum 



Body elongate, gradually widening backward to beyond mid- 

 dle of abdomen. Head horizontal, anteocular part between 

 eyes and antennae and postocular part parallel-sided, a short 

 longitudinal impression behind clypeus, the slender juga longly 

 spinously produced beyond clypeus, eyes slightly prominent, 

 seen from above much longer than broad, the small ocelli placed 

 a little behind the level of the posterior angles of the eyes and 

 as far from them as from one another, bucculae rather short 

 and low, somewhat longer than high, triangular, their anterior 

 and inferior margins straight, antennae somewhat shorter than 

 the body, first joint a little longer than the head, robust, 

 triquetrous, turning one edge downward, one upward, and one 

 inward, second joint subcylindrical, but with the apical third 

 compressedly clavate, third more slender and much shorter than 

 second, with the apex incrassate and obliquely truncate, fourth 

 much the shortest, fusiform; rostrum reaching middle of meta- 

 sternum, first joint not reaching base of head, second a little 

 shorter than first and much shorter than the last two together, 

 fourth somewhat longer than third and subequal to second. 

 Pronotum slightly sloping, somewhat longer than broad.
