﻿272 [May, 



strongly bisinuous at the base, the median lobe squarely truncated behind ; fore 

 angles much produced ; broadly channelled at the sides, which are margined, the 

 edges a little thickened, and crenulated anteriorly, one crenulation — just before the 

 angle — being particularly well-marked, forming a positive triangular excision : scu- 

 tellum golden -green : elytra convex; the humeral angle very prominent; each with 

 nine (besides the usual short scutellar one) rows of close set, large, oblong punctures 

 or foveas, which are connected together, in line, by narrow lines or striaa ; posteriorly 

 and at the sides these punctures become more crowded and confused, running more 

 or less into each other and forming veritable sulci, with narrow, convex spaces 

 between them ; the intervals down the middle nearly flat and — apparently — smooth : 

 it is somewhat difficult to catch the exact colors of the elytra owing to a slight 

 iridescence, but in a certain light the space, or interval, down each side the suture 

 and the intervals 3, 4, 7 and 8 appear vivid green, whilst 2, 5, 6 and 9 appear coppery- 

 brown, under-side and legs shining, reddish-brown tinged with golden-green ; 3 first 

 joints of the abdomen coarsely longitudinally wrinkled and punctured ; femora and 

 tibia? closely punctured, the latter golden-brown ; antenna? and tarsi reddish-brown. 



Hab. Nicaragua. Chontales. 



The present species exhibits a considerable departure from the 

 type, but its differences are not such, I conceive, as to warrant its 

 erection into a distinct genus. The main points of departure from the 

 type are : the head shorter, the epistoma strongly and distinctly se- 

 parated from the front ; the last joint of the labial palpi* shorter, much 

 more produced and rounded on the inner side, thicker (a transverse 

 section showing almost a perfect oval) ; the strongly produced anterior 

 angle of the prothorax, the lateral edge in part crenulated, the median 

 basal lobe squarely truncated behind ; and the totally different style of 

 sculpturation on the elytra. Also one of the novelties discovered by 

 Mr. E. Janson, Jun. 



Taepela, n. g. 



Characters of Nautes (especially of the preceding species) : differs 

 in having the niesosternum declivous and broadly excavated in front (not 

 horizontal, and sharply triangularly notched in front as in Nautes) ; the 

 prosternum bent down behind theanterior co#<^,then expanded and termina- 

 ting in a broad point; the form narrower, more elongate, more parallel and 

 more depressed ; the prothorax squarer, the anterior angles very strongly 

 produced — extending nearly to the upper edge of the eyes ; and the 

 lateral margins strongly crenulated.
