1360 COLEOPTEEA 



of the head. Scutellum triangular, its apex sharp, the lateral su- 

 tures very fine ; it is minutely punctate. Elytra slightly wider 

 behind the shoulders than at the base, very gradually narrowed 

 posteriorly ; on each there is a fine sutural stria, which does not 

 reach the base, and two or three very obsolete abbreviated striae 

 behind ; the sculpture resembles that of a Choleva — that is, it con- 

 sists of transverse linear impressions. 



Underside black, subopaque, covered with fine, depressed, yel- 

 lowish hairs, without distinct punctuation.

Boatman's, Westlaud. Mr. A. T. Cavell was kind enough to 

 send me two examples of this curious and important little insect. 

 I found a single specimen at Stratford, near Mount Egmont, which 

 does not agree exactly with the type : this leads me to think that 

 other closely-allied species exist.

2381. N. cervina, i^-s- Oblong-ovate, fuscous, densely covered 

 with depressed, small round scales ; these are brownish-grey for the 

 most part, very few are grey, but some dark ones cause the middle 

 of the thorax, and an elongate spot near each of its sides, at the 

 base, to appear fuscous ; there are also irregular dark marks on the 

 elytra ; the setae on the wing-cases are grey, erect, and rather long, 

 but those on the thorax are slender and yellowish ; the antennae are 

 red, the legs infuscate-red. 



Thorax as long as broad, its sides rounded, widest behind the 

 middle, its punctuation hidden. Scutellum small. Elytra subovate, 

 very little wider than the thorax at the base, the suture somewhat 

 raised posteriorly ; finely striate, the striae not distinctly punctured, 

 but with some slender depressed setae. Scape much incrassate 

 apically, this portion wdth moderately coarse setae, the base nearly 

 glabrous. Funiculus with greyish hairs, the second joint rather 

 shorter and more slender than the first, 3-6 bead-like, seventh a 

 little larger than sixth ; club elongate-oval, subacuminate, densely 

 pubescent. 



Underside fuscous, with greyish hairs ; basal ventral segment 

 largest, second longer than the metasternum, third and fourth, at 

 the sides only, as long as the second. 



The mandibular scar is indistinct. The scrobe has a very shallow, 

 oblique prolongation. The corbels are not cavernous. There are no 

 ocular lobes. 



N. cinerea is the nearest ally, but the peculiar brassy squamae 

 are distinctive. N. concinna is larger, with a larger, densely-clothed 

 scutellum, and two distinct dark basal spots on the thoi'ax, in addi- 

 tion to other differences. The eyes in N. cervina are more convex 

 than in either of these species, and, though nearly round, extend 

 longitudinally rather than downwards.
