302 Mr. F. Bates's descriptions of 



rather strongly punctured, more or less rugosely so be- 

 tween the eyes, the impressions at each side the front 

 distinctly connected behind ; prothorax moderately con- 

 vex, of the same form as in gigantea, but the base is a little 

 more sinuate, the punctuation irregular but rather large, 

 lightly but distinctly impressed down the median line ; 

 scutellum blue, or bluish-black, acutely pointed behind, 

 impressed down the middle at the base ; elytra moderately 

 convex, oblong oval ; sides scarcely sinuate, not broadly 

 margined ; moderately punctate-striate, the intervals a 

 little convex, sparsely and very minutely punctulate and 

 delicately but rather closely alutaceous; underside bril- 

 liant golden-green ; legs and basal joints of antennte dark 

 shining chestnut-brown; prosternal process as in gigantea.

Nesogena castaneijjes, n. sp. 



Similar in coloration to Fairmfiirii, but more feneons, 

 the prothorax relatively longer and narrower, the sides 

 expanded from the apex to nearer the base, thence 

 parallel to the hind angles ; base scarcely at all sinuate ; 

 the elytra less oblong, more rounded at the sides, more 

 convex, especially near the base ; the prosternum closely 

 curved round the cox^e ; and the size much smaller. 



Head finely irregularly punctured, not very closely nor 

 rugosely so on the front, the groove at each side indis- 

 tinctly connected behind ; prothorax punctured as in the 

 jireceding ; scutellum blue, ])ointed behind, punctured ; 

 elytra rather finely but somewhat deeply punctate-striate, 

 the intervals rather convex, less closely alutaceous than in 

 the preceding ; underside brilliant golden-green, a little 

 coppery at the sides ; flanks of prothorax nearly smooth, 

 not coarsely longitudinally wrinkled, as it is in all the 

 preceding species ; prosternum closely curved roimd the 

 coxffi; legs and basal joints of antennge shining casta- 

 neous ; palpi piceous ; apex of epistoma, and labrum, dull 

 red.
