170 THE ENTOMOLOGIST. 



liturata, Fall., with two or three angular marks on the thorax, 

 is much the most abundant. Both vary in the colour of the 

 legs and elytra to a deep smoky colour. These variations 

 are not, however, alluded to by any of the European authors. 

 One characteristic mark is the black streak on the inner edge 

 of the femora, which is rarely entirely absent. 



12. hicolor, Panz. (1792). Mars. 48. 3— 3|^ lines.— Hufo- 

 testaceous, with the posterior knees black. This species is 

 comparatively constant in its colouring ; occasionally the 

 knees are concolorous, but I have never seen varieties in the 

 colour of the elytra, though Kiesenwetter has described them 

 from the Pyrenees. It is by no means rare in temperate 

 Europe, and is easily recognized. Its large subquadrate 

 head is a very conspicuous charactei*. 



13. thoracicus, 01. (1790). Mars. 52. 2^— 3 lines.— Tes- 

 taceous ; head at the base and elytra pitchy black. The yel- 

 low scutellum, legs and abdomen separate this at once from 

 the following, with which it occurs, but more rarely. It is 

 by no means uncommon in the fens of Norfolk and Cam- 

 bridge. 



14. fulvicollis, F. (1792). Mars. 51. 2^ — 3j lines. Var. 

 flavilabris, Fall. — Black, with the thorax, apex of the abdo- 

 men, and legs red ; elytra deeply granulated ; tarsal claws 

 with a strong tooth. This species is extremely variable, but 

 the elytral sculpture will serve to characterize it throughout. 

 It is almost universally divided into two species : Mr. Water- 

 house first united them in his ' Catalogue,' a step which has 

 been adopted, and I think with reason, by M. Thomson. 

 The darker varieties of T. flavilabris, in which the black co- 

 lour invades all the insect but the extreme angles of the 

 thorax, are very rare and little known on the Continent. 

 Almost any gradation may be found between this and the 

 fulvicollis, and they are frequently found in company. 



16. paiudosus, Fall. (1807). Mars. 54. 2 — 2|- lines. — 

 Black ; knees, and occasionally the extreme margin of the 

 thorax, testaceous. The small size and uniformly black hue 

 separate this from any sj)ecies, except the elongata. Fall., 

 wdiich is a true Rhagonycha, and has longer, paler legs, and 

 is a differently-formed and larger insect. 



16. lateralis, L. Mars. 55. 2 — 3 lines. Ovalis, Germ. 

 — Rufo-testaceous ; vertex and elytra black, the latter with
