him seems to be a female, and he probably knew only one sex, 

 as he says nothing of the strong sexual differences in the struc- 

 ture of the pronotum.

The antennge, as described by Distant, are "pale stramineous," 

 but the first joint is always blackish at the base; the fourth 

 joint is somewhat thickened, but by no means "globose" as 

 described by Distant. The membrane is pellucid, shaded with 

 brownish and variegated with fuscous; the veins are usually 

 whitish. 



Previously known only from Ceylon; in the Philippines it 

 seems to be a common insect. 



Breddin has united the genus Entisberus with Pamera, but 

 in this he was totally mistaken. The new species described by 

 him under the name Pamera {Entisberus) subsericea is an 

 ordinary Pamera and has nothing to do with Entisberus. 



Genus DUDIA novum 



Body oblong. Head a little broader than long and broader 

 than apex of pronotum, rather strongly declivous (45°), seen 

 from the side conical, eyes prominent, vertex about three times 

 broader than an eye, antenniferous tubercles placed immediately 

 before the eyes, first joint of antennae half the length of the head, 

 slightly passing its apex, second one-half longer than first, 

 clavate at apex, third somewhat shorter than -second but a little 

 longer than first, fourth subequal to third, bucculse very short, 

 rostrum reaching middle coxae, first joint reaching base of head, 

 a little longer than first antennal joint, second joint a little 

 longer than first, third subequal to first. Pronotum broader 

 than long and a little over twice broader than head, rather 

 strongly narrowed from base to apex, transversely impressed a 

 little behind the middle where it is somewhat constricted, collar 

 narrow, posterior lobe a little sloping, its basal margin slightly 

 rounded, anterior lobe transversely and longitudinally highly 

 convex, its apical half strongly declivous, the lateral margins 

 obtuse, a little rounded. Scutellum broader than long, convex. 

 Prosternum seen in profile angularly sinuate, separated from 

 anterior lobe of pronotum by a narrow, smooth, subimpressed 

 line. Metapleura with acute posterior angles. Elytra reach-
