tellum long, subtriangular, black ; elytra wider than the prothorax, the 

 sides nearly parallel, coarsely and closely punctured, a semicircular 

 band at the base enclosing the shoulder, a zigzag at the middle, and a 

 straight narrow band towards the apex black; legs pale testaceous, 

 the femora clavate, shining, ferruginous, the base pale ; body beneath 

 nearly glabrous, brown, darker on the throat and breast. Length ?A 

 lines. 



The nearest ally of this species appears to be signiferwm, 



Ncwru., a much darker and differently marked, insect. The latter, 



together with C. scutellare, Fab. ( piceum, Newm.), is referred to 



a genus neither named nor described by that author, but for which Mr. 

 White has adopted, also without description, the name of Callidiopis 

 (Blanch.). I don't know what the characters may be which arc to 

 distinguish it from the polymorphous Callidiwm. The antennae and 

 prothorax are as variable as the coloration.

Tmesistermis e.varatus. 



T. chalceo-fuscus, griseo maculatus ; prothorace valde transverso ; elytris 

 fortiter sulcatis, interstitiis elevatis, faseiis griseis interruptis ornatis, 

 apice extus spinosis.

Robust, dark bronze-brown, more or less spotted with patches of 

 greyish hairs; head broad in front, nan-owed behind the eyes, two 

 slightly raised lines forming a A above the epistome, the vertex cana- 

 liculate, four to six spots in a line beneath the eyes, two between and 

 four behind them ; prothorax very transverse, rounded and narrowed 

 anteriorly in the male, the border in front nearly straight, dilated ante- 

 riorly in the female, and the border broadly emarginate for the recep- 

 tion of the head, dull bronze, coarsely punctured at the side, leaving a 

 broad, smooth, shining line in the middle ; scutellum transverse, 

 rounded behind; elytra strongly sulcated, the interstices forming 

 broad, raised lines, the central ones more or less united posteriorly and 

 not reaching the apex, the sulcated lines filled in here and there with 

 a greyish pile, forming partial spots which assume the appearance of 

 interrupted bands (two or three — in some individuals scarcely ap- 

 parent), apex strongly spined externally ; legs and antennae sparsely 

 pubescent ; body beneath glossy chestnut-brown, a single white spot 

 on each side of each abdominal segment. Length 9 lines. 

 The nearest affinity of this well-marked species is with S. sidcati- 



pennis, Blanch., from which, amongst other characters, it is distin- 

 guished by its metallic colour and apiculate elytra.
