RHYNCHOPHORA.

There seems to be considerable confusion with regard to the two 

 preceding species, more especially T. junceus ; I have several specimens 

 of both T. tomentosus and T. junceus from Dr. Power's collection before 

 me, and the latter insect is smaller and narrower and more grey in 

 appearance than the former, and has the suture of the elytra uni- 

 colorous ; Thomson, however (Skand. Col. vii. p. 302), speaks of 

 T. junceus as broader than T. tomentosus,, and as having the suture fur- 

 nished with white scales ; he mentions, however, that the femora and 

 rostrum are darker in the former species, -which appears to be the case ; 

 in some way or other he seems to have confused the two insects, which 

 are certainly closely allied ; the descriptions of Schonherr referred to by 

 Thomson (Gen. et Spec. Cure. III. 411, 15 & 412, 17), are very slight 

 and of little practical use in separating the two species. 



T. tibialis, Boh. (nigrirostris, "Wat.). Oblong, convex, black with 

 the antenna?, tibiae and tarsi red, apex of the former dark ; upper side 

 covered with uniform grey pubescence, which is lighter on the under- 

 side ; rostrum dark, reddish at apex ; thorax subtransverse, with the 

 sides rounded, usually with a fine fringe of white hairs at base ; elytra 

 rather long, with distinct striae, which are not covered by the pubescence ; 

 femora dark, tibias usually more or less infuscate at extreme base.

T. pyg-maeus, Bris. (breuicornis, Wat. ; pusiUus, Germ.?). Ex- 

 tremely like the preceding, and chiefly distinguished by its very small 

 size ; oblong, convex, black, with the antennae red at base and dark at 

 apex ; underside with fine white scales, upper surface with grey 

 pubescence ; rostrum dark ; thorax subtransveree with the sides moder- 

 ately rounded ; elytra with distinct punctured striae, pubescence 

 often thicker on suture; femora dark, tibiae and tarsi red. L. 1|-1|

MICCOTROGUS, Schonherr. 



Six European species belong to this genus ; they differ in no way 

 from the ordinary species of Tychius except in the fact that the ftini- 

 culus of the antenna3 is six-jointed ; like them they are found on 

 PapHionaceae our single species is the commonest member of the tribe 

 that is found in Britain. 



1*1. picirostris, F. Oblong, convex, black, with the base of the 

 antennae and the tibiae and tar.-i ferruginous, apex of the former and
