the extremity, suture and interstices with minute serial punctures, the 

 2nd from the suture somewhat elevated and abruptly bent outwards at the 

 extremity. 



Underside dark rufous, shining, nearly glabrous, the slender pubescence 

 most easily detected on the terminal ventral segment ; the punctuation no- 

 where close, rather fine, slightly coarser on the prosternum. Metasternum 

 with a short linear impression behind, not sulcate along the middle. 



Female. — Rostrum arched above, moderately slender.

Near 926 ; the rostrum not as broad ; scape rather more curvate ; the

Body slightly convex, narrow, subparallel, sparingly clothed with slender

Male. — Rostrum quite half the length of thorax, evidently but not 

 abruptly narrowed behind the middle, stout, its frontal portion nearly as 

 broad as the head. Scape inserted between the middle and apex, reaching 

 the front of the eye, a little curved, its apical half subclavate. Funiculus 

 rather laxly articulated, joints 2-4 narrowed towards the base, 5th sub- 

 moniliform and transverse, 2nd longer than 3rd. Club oblong-oval. Head 

 moderately narrowed anteriorly, but with a distinct sculptured plica or 

 swelling which at each side extends just beyond the back of the eye. Eyes 

 small, quite lateral, slightly prominent. Thorax triangularly ovate, con- 

 stricted in front. Scutellum small. Elytra elongate, parallel as far as the 

 hind thighs, slightly narrower than thorax. Legs rather elongate and 

 slender; tarsi densely pilose underneath, their 3rd joint cleft almost to 

 its base, with strongly developed and divergent lobes. Underside with short 

 distinct yellowish hairs, moderately finely but distinctly punctured, the 

 intervals densely and minutely sculptured. The prosternum elongate, the 

 coxee much less separated than in Pentarthrum, with a distinct suture between 

 them. Mesosternal suture well marked. Metasterniim shorter than the 

 abdomen, medially sulcate. Basal 2 ventral segments broadly depressed 

 medially, their suture sinuate and distinct. 



Female. — Rostrum more slender, on a lower level than the vertex, por- 

 rect ; widest at the apex, gradually narrowed towards the middle, slightly 

 dilated, at or just before the middle, where the antennae are placed, its basal 

 half distinctly medially narrowed, almost abruptly contracted underneath. 

 Head without any visible post-ocular plication. Metasternal groove ab- 

 breviated. Abdominal depression shallow, the last 3 segments red, as in 

 the other sex. 



Differs from Euophryum in being without any dilatation below the 

 rostrum, in its longer scape being inserted nearer the apex, by the presence
