31, Trichyorhyssemus (gen. nov,) hirsutus, C. cle P., sp.n. 



A specimen sent to M. L. Clonet des Pesruches was kindly 

 examined by him and returned with this name, which will be 

 published in his forthcoming monograph. 



CETOXIID^. 

 32. Protsetia andrewsi, Gahan, sp.n. (PL X, Fig. 5.) 



Nigra, nitida, interdum viride vel purpureo tincta, supra sparse 

 setosa, thorace subtus pedibusque sparse sat longeque villosis ; 

 clypeo transverse, margine antico late rotundato (fere truncate) et 

 fortiter elevato : capite pronotoque sat dense fortiterque punctatis, 

 longitudinaliter in medio obtuse le^dterque carinatis ; elytris dense 

 punctatis, squamis luteis sparse guttatis, depressionibus posticis 

 baud vel obsolete striatis, marginibus suturalibus postice elevatis 

 et ad angulos apicales paullo productis. 



Long. 12-15, lat. 6-5-8-5 mm. 



Colour black, but in some specimens tinged with metallic green 

 or purple. Head strongly and rather thickly punctured, clypeus 

 transverse, broadly rounded or almost truncate in front, with the 

 margin strongly raised. Pronotum with an obtuse and very feebly 

 raised carina along the middle ; this carina, a median space at the 

 base in front of the scutellum, and one or two smaller areas towards 

 the sides, smooth, the rest of the surface strongly and rather thickly 

 punctured. Elytra somewhat strongly punctured, the punctures 

 being less thickly placed in the neighbourhood of the scutellum 

 than over the rest of the surface ; the broad depression on each 

 side of the sutural carina on the posterior half of the elytra is 

 rather thickly punctured and usually destitute of striae (in one or 

 two specimens among those examined traces of strice in the form of 

 one or two broken lines are to be seen). Antennae varying in colour 

 from light mahogany -brown to dark chestnut-brown ; the inner 

 lamella of club almost as long as the whole of the proximal part 

 of the antenna. Legs and under-side of the body with a long 

 sparse pubescence ; metastemum with an impressed line along 

 the middle. 



This species seems to come nearest to P. acuminata, Fab., from 

 which, however, it is very distinct. It differs not only in colour 

 and sculpture, but in being more pubescent above and below and in 

 having the anterior margin of the clypeus more strongly raised, 

 the apices of the elytra less produced at the sutural angles, the 

 metastemum impressed with a median line, and the hair-fringe of 

 the intennediate and hind tibiis much longer and more sparse.
