stated that the " second joint is concealed and the third slightly 

 longer than the second, second to tenth subequal, eleventh 

 elongate." I suspect this means that the fourth is slightly 

 longer than the third, but it certainly cannot mean that the third 

 is if anything longer than the fourth, which is the case in the 

 species before me. The colouring of this insect (quite constant 

 in all the examples I have seen) also differs from that of the two 

 species with which I am comparing it, the black discal patch on 

 the elytra extending from the inner margin of the external 

 elytral costa to the outer margin of the sutural carina, and 

 leaving the apex red for the length of scarcely one-seventh part 

 of the length of the elytra. The intermediate longitudinal 

 elevated lines on the elytra are strongest near the base (where 

 they are scarcely different from the costse) and are distinctly 

 traceable nearly to the apex. This insect might be suspected of 

 being a variety of M. lineatus, Waterh., but inter alia its 

 antennae are incompatible, for in the male they resemble those of 

 inquinulum, Waterh. (same sex), as figured by Mr. Waterhouse; 

 while those of lineatus (male, — not figured by Waterhouse) are 

 like Mr. Waterhouse's figure of the antennae of Trichalus 

 Jlavopictus, Waterh.

M. rufipennis, Fab. I have little doubt that Mr. Waterhouse is 

 right in thinking (though he is not very confident on the point) 

 that his salebrosum is identical with Fabricius' species. 



M. marginatus, Er. T should say there is no doubt that 

 M. hcemorrhoidalis, Waterh., is identical with this species. I 

 cannot however agree with Mr. Waterhouse (Typ. Br. Mus., Lye.) 

 that his hcemorrhoidalis may be a colour var. of rufipennis, Fab. 

 The two are unquestionably closely allied apart from colour ; but 

 there is a very marked difference in the antennae, the produced 

 piece of each joint beginning with the sixth being in rufipennis 

 very much more slender than in hcemorrhoidalis ( = marginatus, 

 Er.).
