234 [JiVLTCh, 
This insect is stated by Mr. Murray (1. c, p. 103) to occur at Raehills and in 
Aberdeenshire. It can by no means, however, be correctly attributed to the true 
A. ater. 
My friend Mr. Morris Young, of Paisley, has recently sent me specimens of it, 
and it is represented in Mr. Waterhouse's collection by two examples (also from 
that gentleman) which are stated in his note-book to have been named A. flavipes 
by Du Val for Mr. Young; — that name, indeed, being still affixed to one of them, 
and written apparently by a foreigner. 
My specimens are nearly equal in length to ordinary examples of A. tristis, 
Schm.,but are considerably broader and more convex and bulky than that insect. They 
are clothed with the dense glittering pubescence peculiar to certain Aleocharidce 
of shore-frequenting habits, and are somewhat roughly but very closely punctured 
on the thorax and head, the latter of which is square behind, and has a tliin longi- 
tudinal shining line on the vertex. The elytra, which are less closely punctured 
than the head and thorax, are slightly shining, as far as the pubescence allows the 
surface to be seen. The darkest specimen is entirely dull black, except the tibiaa 
and base of the tarsi, which are pitchy-brown ; and the lightest one (out of six) 
exhibits the faintest possible trace of a dark brown humeral blotch, and has the 
femora and antennae pitchy-brown, and the tibiae and tarsi light reddish-testaceous. 
La Perte, Mon. Anth., 222, states the type of A.fiavipes to be brownish-black, 
with an oblong obsolete chestnut-brown humeral spot, and the antennae and legs 
entirely testaceous. His darkest form (A. rufipes, Payk.) is entirely black, with 
brown femora, and the tibias, tarsi, and antennae of a ferruginous red, more or less 
dark ; and I presume it is to this form that these Scotch specimens are to be 
referred. If distinct from it, as is very probable, they must nevertheless be closely 
allied to it ; as they do not agree at all with any other species in La Ferte's mono- 
graph. That author gives the length as " 0,0017 arf 0,002 ;" which can hardly fail 
to be a misprint, — though not noticed in the list-of errata. 
Thomson gives f of a line for the length of A. fiavipcs ; whereas my largest 
specimen exceeds li lin. 
The specimens representing A. flavipes in the European collection of the Brit. 
Mus. cannot be reconciled with my insects. 
22. Thyamis 26 sp.— ? Cat. p. 94, and Pocket Cat. p. 33. This insect is, I 
believe, intended to be represented by the T. lateralis, 111., of the 1st Edn. of Mr. 
Crotch's Cat., and was, indeed (as I am informed), so named for that gentleman by 
M. Allard ; who, subsequently (as Mr. Crotch remarks, Ent. 35, 174), on finding 
that it could not be rightly attributed to that species (of which Mr. Waterhouse 
was well aware, having continental types agreeing with Illiger's insect), has pro- 
posed for it the name of T. 2>ci>truelis, under which it appears in the 2nd Edn. of Mr. 
Crotch's Cat. 
The species is allied to T. melanocephala, but differs from that insect in being 
smaller and with less evident shoulders to the elytra, which are more deeply pxmc- 
tured, the punctures running somewhat into strias. Mr. Waterhouse's specimens 
were taken at Daronth, about the end of June, on Verhascum.
