The sliortness of the third iuiteiinal sewmtiit is ii ver}' jiccnliar chiiracter. Tin's 

 species and pi/ladi's agree in tlie broad jirothorax beiug cariuil'orm at the side. They 

 form perhaps a genus distinct from Euci/clotropis.

c?. Enfescoiit brown, variegated with a coarse brown and clay pubescence. 

 Ujijierside of head and rostrnm in a ])hxne, greyish clay, coarsely punctate-rngate. 

 Antenna! groove occupying four-tifths of the side of the rostrum, rounded behind 

 and below ; its upper edge cariniform, slightly covering the groove. Lobes of false 

 mentum subaciiminate. Antennal segments 1 and 2 rufous, the others rufescent 

 (7 to 11 missing), 3 nearly as long as 1 +2, a little longer than 4, reaching nearly 

 to middle of prothorax. Prothorax twice as broad as long, coarsely rugate, greyisli 

 clay apically at sides, broader apically than head inclusive of eyes, widest at 

 antebasal carina, gradually rounded-narmwed from carina forwards, longer above 

 tlian at side, carina at basal sixth, lateral portion of the same short, but side of 

 prothorax itself cariniform, so that the carina ai)pears to be continued to a]iex, basal 

 longitudinal carina feebly marked, forming a very acute angle with the obliijue 

 lateral portion of the dorsal carina. Scutellnra greyisli clay, rounded, small. 

 Elytra short, convex, coarsely punctate-striate, the interspaces more or less 

 convex, especially the alternate ones, which are rather distinctly tess(dated or 

 dotted witli brown-black and greyish clay ; middle of third interspace black ; sub- 

 basal and fipical areas rather more densely clayish than rest of elytra. Pygidium 

 semicircular, greyish clay. Sterna punctate at sides. Prosternum very sliort 

 mesially, transversely sulcate. Mesosternal process narrow, rounded at apex. 

 Metasternum mesially shorter than first abdominal segment. A narrow ante- 

 median ring on tibiae and apical half or third rufous, jmbescent clayish grey. 

 Tibiae hooked at apex (tJ).

<J. Rostrum flat, rather thin, widest near tip, longer than broad, not carinate, 

 truncate, with trace of sinus. Frons and occiput slightly receding, not qnite in 

 a plane with rostrnm. Underlip flat, sinuate, not divided down to insertion of 

 ])alpus. Lobes of false mentum rounded at apex. Antennal groove lateral, covered, 

 produced forward, sharply limited behind and below, distant from eye, occupying 

 •apical half of side. Antenna long, segment 1 incrassate, short, 2 thinner and 

 somewhat longer, .3 to 7 very thin, of nearly equal length, 3 the longest, more 

 than twice as long as 2, 8 rather thicker, but not triangular, longer than 9, this 

 triangular, truncate at apex, nearly twice as long as broad, half as long again 

 as lU, this also triangular with the sides rounded, 11 ovate, a little longer than 

 10, all the segments with some rather long hairs, club somewhat pilose beneath, 

 but not so hairy as in J ktsi/rliopala and J,a//ojj(:~us. Eye lateral, somewhat 

 elliptical, rather coarsely granulate, indistinctly emarginate. Prothorax longest 

 above, slightly sinuate at ajiex above in middle, conical, one-fourth broader than 

 long, carina at basal eighth, straight, feebly concave laterally, flexed forward in an 

 even areli, not extending to middle, subbasal carina complete, very distinct, basal
