COPH^ESTHETUS, n. gen. 



General form of Eubria bnt a little more oblong. $ Antenna; 

 witli the fifth to tenth joints with the inner apical angle 

 produced into a long thick branch ; the eleventh joint very long, 

 having the form of the branch of the tenth. Apical joint of 

 the maxillary palpi elongate, svibparalled, the apex flattened, very 

 slightly arcuate, almost truncate. The apical joint of the labial 

 palpi is similar, but less elongate. Prosternal process a little 

 enlarged at its apex, obtuse. Mesosternum horizontal, emarginate 

 in front to receive the prosternal process. The rest as in 

 Schinostethus. 



The form of the apical joint of the palpi, and the blunt 

 prosternal process are the characters upon which I separate this 

 from Schinostethus; the difference in the structure of the 

 antennae may be only sexual. 



Cophcethetus opacus, n. sp. 



Oblongus, convexiis, opacus, fuscus ; thoracis lateril:)us ferru- 

 gineis, prosterno pedibusque flavo-ferrugineis. Long. 1^ hn. 



Antenna; with the two basal joints pitchy. All the upper 

 surface of the insect opaque, with very short close pubescence, 

 only visible with a high magnifying power. Thorax nearly as 

 in Eubria palustris, but with the sides rather more arcuate, 

 and more semicirciilarly emarginate in front ; there is a slight 

 impression on each side of the middle of the base; the posterior 

 angles are a trifle less than right angles; the basal margin has 

 the same serrate appeai-ance as in Schimistethiis l)ut in a less 

 marked manner. Scutellum nearly an equilateral triangle. 

 Elytra dark fuscous, the fine pubescence rather paler ; tlie 

 surface posteriorly is finely vermiculate; the pubescence shows 

 itself particularly in two narrow curved lines on the back, 

 arising in the middle of the base, and turning towards the suture 

 of the elytra. 



Hab. Java (J. C. Bowring, Esq.). 



A single example only, not in perfect condition. I have, 

 however, described it on account of its great interest, as having 

 the antenna; branched as in some Cyphoiiifla', but undoubtedly 

 closely allied to ,Schinostethvs, Avhich closely approaches Tyche- 

 pstphns, placed by me in the Pscphcnida'. T cannot, however, 

 alter my opinion as to the position of Tychapsejihns, which has 

 the prosternum produced anteriorly, so as partly to cover the 

 loAver part of the head as in Parnns, — a character wanting in 

 Schinostetlius.
