Underside fusco-iiii'uus, with unevenly distributed yeihnvish pubes- 

 cence. Mctasternuni nearly glabrous and ilei)ressed along the middle; 

 close to this, and at each side of it, there is a strcmgly elevated vertical 

 process Avhieli is l)iiid at the summit. Basal ventral segment pubescent 

 and covered by tlie femora, 3rd sliglitly longer than the adjoining ones; 

 5th semicircularly eniarginatc, only a little longer than its juedeccssor 

 in tlie middle; 6th rather larger than Hth, sliglitly foveate in the centre, 

 snl)truncate behind; 7th minute, broadly triangular, and resting on 

 tlie large operculum ov terminal segment, which is roun.ded and dis- 

 tinctly margined behind. 



// . sf(rii(ilh, 2744, most nearly resembles this; in it, however, the 

 head and tliorax arc shorter and broader. The metasternal j^rocess, at 

 each side of the middle, is close to the intermediate coxa, it is entire, 

 and vertical in frf)nt ; in //. (iiir/ulipes each jirocess is situated exactly 

 at the middle, distant from the coxa, and is bifid at its extremity. In 

 2744 the .")th venti'al segment has a transverse median depression, and 

 the Gth is concave for half of its whole width, the minute 7th is broadly 

 ti'i angular.

Elongate, nai'rowed anteriorly, shining; castaneo-rufous, antennae, 

 palpi, and tarsi more or less fulvescent ; pubescence yellow, depressed, 

 very thinly distributed, more thickly at the extremity of the elytra 

 and almost forming a cilium there. 



Head elongate, its sides nearly sti-aiglit in fi'ont of the moderately 

 large eyes, much narrowed behind them, not quite smooth; the frontal 

 channel extends as far back as the middle of the eyes, it is slightly but 

 not at all abruptly expanded there and almost touches the pair of 

 foveae behind tlie eyes, its hind part is convex. Tliorax convex, and, 

 excluding the distinct minutely and densely sculptured neck, rather 

 longer than broad, widest at the middle; with a curvate impression in 

 front of the base and a small elongate fovea at each side. Elytra about 

 a third longer than the thorax, widest behind, considerably narrowed 

 towards the base, bearing only a few depressed straight hairs; the 

 sutural striae arc very fine, but alongside each there is a broad flattened 

 space, w-hich is deep and foveiform at the base but obsolete towards the 

 extremity, there is a similarly formed but much shorter impression near 

 each shoulder. Hind-body as long and fully as l)road as the elytra, 

 basal segment about as long as the other delh-xed ones taken together, 

 with a few fine, slightly curled hairs. 



Legs elongate, femora subclavate, tibiae arclied exti'rnally, thickene<l 

 towards the extremity and distinctly jiubescent there. 



Antennae slightly longer than the head and thorax ; basal joint red, 

 its length doidale tlie breadth, 2nd nearly as thick and fully half as 

 long; 3rd more slender and longer than the 2nd and distinctly longer 

 than the 4th: joints 5-8 nearly o«|ual, all evidently longer than broad;
