DESCRIPTIOX OF A NEW GENUS AND SPECIES OF 

 COLEOPTERA (FAMILY HISPID.E) FROM NEW 

 BRITAIN. 



By David Sharp, M.B., F.R.S. 



(Communicated by W. ^^. Froggatt.) 



Brontispa, n.gen. Chrysomelidarum ( Hispides, Group Cryftony- 



chites.) 



Corpus perelongatum, depressum. Caput inter antennas pro- 

 ductum, acuminatum, medio canaliculatum. Elytra regulariter 

 seriatim punctata, interstitiis lequalibus, nullo modo costatis. 



This genus may be placed between Cryptonychus and Oxyce- 

 jyhala. The simply acuminate spinose projection on the front of 

 the head, and the remarkably even surface (very regularly punc- 

 tured) of the extremely elongate elytra, are sufficient to distinguish 

 it. It has another remarkable character : on the under surface 

 of the head, the parts of the mouth are not closely applied to the 

 front of the prosternum, but are separated from it by a curved 

 ridge running all across the head in correspondence with the 

 curve of the front of the prosternum. 



Brontispa froggatti, n.sp. 



Elongata, depressa, subparallela, rufotestacea, elytris nigro- 

 suffusis, interdum fere totaliter rufo-testaceis, interdum omnino 

 nigris, corpore subtus plus minusve nigro-suffuso; antennis elon- 

 gatis nigricantibus. Long. 9 mm., cap. |, thor. H, elytris 6|- 

 7 mm.; lat. 2 mm. 



Colour reddish-3'ellow, suffused with black to a variable extent, 

 but with the prothorax always in larger part red. Antennae 

 2J mm. long; the terminal four joints closely articulated, elongate, 

 dull, the other joints shining, with the sutures between them
