o(ifi Mr. Waterhouse's tlescriptlons of 



COPH^STHETUS, 11, gen. 



Geueral form of Euhria but a little more oblong. $ Aiiteuu* 

 with the fifth to tenth joints with the inner apical' angle 

 ])roduced 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, subparalled, 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. Mesosteruum horizontal, emarginatc 

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

 Scliinostetlius. 



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

 ])rosternal process are the characters upon which I separate this 

 from Schinostethns ; the difference in the structure of the 

 antennae may be only sexual. 



Copha'thefits opacns, u. ,sp. 



Oblongus, convexus, opacus, fuscus ; thoracis lateribus ferru- 

 gineis, prosterno pedibusque flavo-ferrugineis. Long. 1-|- liu. 



Antennfe with the tAvo 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 Euhria palnstris, but with the sides rather more arcuate, 

 and more semicircularly emai-ginate 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 appearance as in Schinostethns but in a less 

 marked manner. Scutellum nearly an equilateral triangle. 

 Elytra dark fuscous, the fine pubescence rather paler ; the 

 surface posteriorly is finely vermiculate; the pubescence shows 

 itself particularly in two narrow curved lines on the back, 

 arising in the middle of tlie 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 Cyi'ihonidrp, but undoubtedly 

 closely allied to Schinostethns, Avhicli closely approaches Tyche- 

 pstplins, placed l)y me in the Psephenidce. I cannot, hoAvever, 

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

 the prosternum produced anteriorly, so as partly to cover the 

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

 Schinostethns.
