310 Mr. G. R. Waterhouse on some new Coleoptera. 



Apocyrtus cuneiformis. 



Ap. niger vol piceo-niger ; pedibus rubris, genibus tarsisque nigris ; corpore 

 cuneiformi, postice latissimo ; rostro crebre punctato, punetis confluenti- 

 bus, sulco lato longitudinali et ad basin linea. transversa, impresso ; capite 

 linea longitudinali impresso; thorace mediocriter convexo in medio vix 

 dilatato, supra rugoso vel subtuberculato ; elytris supra crebre punctatis, 

 punetis confluentibus, subdepressis, ad basin quoad latitudinem vix cum 

 thorace coaequalibus ; squamis minutis casruleis corpore superiore ad- 

 sperso. Long. corp. 5-f — 4-J- lin. ; lat. 24 — H Un. 



The very small blue scales on the head, thorax and elytra of this 

 insect are very indistinct, requiring a lens to perceive them ; they 

 are moreover so scattered as scarcely to affect the general ground- 

 colouring. 



Apocyrtus sub cuneiformis. 



Ap. rufo-piceus ; pedibus rufis, antennis, genibus, tarsisque nigris ; corpore 

 subdepresso, subcuneiformi ; thorace rugoso ; elytris supra depressis cre- 

 bre subseriatim punctatis, tuberculo suturali versus apicem instructis, pilis 

 vestito. Long. corp. 6 lin. — 5 lin. ; lat. 3 — 2-j- lin. 



This species very closely resembles the A. cuneiformis, but differs 

 in having the thorax proportionately narrower, the elytra broader, 

 more decidedly depressed above, and the broadest part is more re- 

 moved from the apex or nearer the middle than in that insect ; the 

 colour is always pitchy red, whereas in A. cuneiformis it is usually 

 black and rarely pitchy ; the sculpturing is rather less strong. Both 

 species were abundant in specimens in Mr. Cuming's collection, but 

 they do not appear to have been collected in the same locality, some 

 of Mr. Cuming's bottles containing one species and some the other. 

 In form the present and preceding species differ considerably from 

 others of the genus : the thorax is less globose, being but little di- 

 lated in the middle ; the elytra are of the same width as the thorax 

 at the base ; thence they gradually become wider — in cuneiformis the 

 upper surface is subdepressed, and the widest portion is near the 

 apex ; in sub cuneiformis the upper surface of the elytra is nearly fiat, 

 but at the sides and apical fourth they suddenly drop as it were, and 

 thus, viewing the insect from above, the rounded angle formed by the 

 sudden descending of the parts mentioned constitutes the outline of 

 the visible portion • at the suture and towards the apex of the elytra 

 is a blunt tubercle, which is furnished with a brush of small hairs. 



Apocyrtus rufescens. 

 Ap. corpore rufescente ; pedibus rufis ; antennis, genibus, tarsisque nigris 

 thorace subcylindrico, in medio vix dilatato, tuberculis minutis crebre ob- 

 sito ; elytris convexis, in medio dilatatis, ad apicem acutis, crebre tuber- 

 culatis, ad latera tuberculis majovibus in seriebus tribus vel quatuor ob- 

 sitis. Long. corp. 5^ — 4-| lin. ; lat. 2l — 2a lin. 



Closely allied to A. cuneiformis and A. sub cuneiformis, >but distin- 

 guished by the elytra being narrower, not depressed above ; the apical 

 portion is more produced, and does not form a right angle with the 

 dorsal surface, but descends gradually : the thorax is thickly studded 

 with minute tubercles, and so are the elytra ; on the sides of the
