deeply grooved each side, with the posterior part of the grooves more 

 deeply sunken. Tylus narrow, high, rounded at tip ; on the con- 

 striction behind it is a minute, elevated granule. Antenniferous 

 processes stout, subacute at tip, extending almost to the tip of the 

 basal joint of the antennae. Antennas very broad, a little flattened, 

 the basal joint very short, not as long as the apical one ; second 

 joint longest, subfusiform, more than twice as long as the apical one, 

 much stouter than the basal ; third equally stout, a little more than 

 one-half the length of the second, apical much narrower than the 

 third, the tip subcorneal. Rostrum reaching fully to the anterior 

 coxae. Pronotum transversely elongate-oval, more than twice as wide 

 as long, the lateral margins remotely denticulated, the teeth decreas- 

 ing in size posteriorly ; anterior margin subtruncated, posterior margin 

 somewhat lobed behind the humeri ; the disk with four longitudinal 

 ridges, the lateral ones incomplete, curving inwards anteriorly, and 

 on each humerus is a short ridge. Margins of the scutellum much 

 elevated. Tibiae pale yellowish, with the base, tip and a broad band 

 on the middle, black. Disk of corium usually reticulated with pale 

 ferruginous, which includes also the two elevated nervures ; mem- 

 brane pale, marmorated with fuscous, and having four long nervules. 

 Middle line of venter incised ; post-genital flaps long and broad, 

 obliquely approaching at tip. Lateral margins of the posterior seg- 

 ments broadly scalloped. 



Length, 5^-7 millims. Humeral breadth, 2-2 £ millims.

Ferruginous, or rufo-fuscous. When deeply colored displaying a 

 large, whitish spot upon the middle of the corium. Antennae stouter 

 than in the allied species, the second joint a little longer than the 

 basal one,* the third almost as long, or at least two-thirds as long as 

 the fourth. Spines of the antenniferous tubercles acute and a little 

 curved. The other characters are those common to the allied 

 species.
