1270 COLEOPTERA 



without punctuation, and has a fine white pubescence on the middle; 

 the transverse line in front of the base strongly angulated on either 

 side. The elytra have a very large prominence on either side of the 

 suture behind the scutellum, and the third interstice from the suture 

 projects at the hinder part so as to form a sort of bulla, the fifth 

 interstice projecting in a similar though slighter manner ; the striae 

 are rather deep, but irregular, and consist of rather coarse punc- 

 tures ; the interstices bear a few small fuscous spots or tufts. 



A specimen of this species was sent by Mr. Helms, and was 

 found on the racecourse. The female is, I believe, unknown. An- 

 thribus meinertzhageni, Broun, is no doubt a Proscoporhinus . The 

 genus was founded on a rare New Caledonian insect, and its discovery 

 in New Zealand is of some interest on this account. The ento- 

 mology of New Caledonia is only very imperfectly known, and we 

 may anticipate that a greater affinity will be found to exist between 

 it and that of New Zealand than is at present suspected. 



Xenanthribus. 



Nov. gen. 



Body convex, short and broad, medially contracted, clothed with 

 moderately short, and very long outstanding, hairs. Rostrum short 

 and broad. Scrobes foveiform, lateral, situated in front of the lower 

 margin of the eyes. Mandibles large, acute at apex. Eyes small, 

 finely facetted, rotundate, indistinctly truncate in front, widely 

 separated above. Antenna moderately short, bearing some elongate 

 hairs ; the basal joints stout and about equal ; 3-6 rather slender, 

 decreasing in length, each longer than broad ; seventh and eighth a 

 little shorter and broader than the preceding one ; club triarticulate, 

 finely pubescent. Thorax with rounded sides, rounded and some- 

 what produced in the middle in front, without lateral margins, and 

 without the usual carina near the base. Scutellum invisible. Elytra 

 short and broad, marginated at the base, humeral angles rounded, 

 of the same width as the thorax at the base, abruptly declivous 

 behind. Pygidium conical. Legs comparatively long and stout, 

 simple ; tarsi stout, third joint deeply bilobed, fourth elongate ; claws 

 provided with elongate denticles. Prosternum widely emarginate in 

 front. Mesosternum about as long as the remarkably short meta- 

 sternum. Coxa moderately narrowly separated, the posterior rather 

 more widely than the others. Abdomen with the basal four segments 

 short, fifth longer but narrower. 



This is distinguished from all the other genera of the Anthribidae 

 known to me by the absence of the basal carina of the thorax. A 

 new group must be added to the family for its reception, having for 

 its differentiating character what I have already indicated.
