Anaspis. ] " HETEROMERA. 79 
There is a considerable amount cf confusion with regard to this species, 
and,as far as I know, we only possess as British the variety thoracica, L., 
which has the head and thorax testaceous yellow and the elytra dark; 
it resembles A. ruficollis, but the latter species has the head black ; it 
is possible that the variety of this latter species with the head red, which 
has not yet been recorded as British, may be standing in some collec- 
tions under A. thoracica ; if so, it may be known by its longer antenne, 
which are not moniliform, shorter thorax, and the presence of appendages 
in the male ; it is also quite possible that the type A. fava may be con- 
fused with A. subtestacea; the antenne, however, of this latter species 
are much longer and not moniliform, with the penultimate joints dis- 
tinctly longer than broad, and the male characters are different; Mul- 
sant (Coléoptéres de France, Longipédes, p. 116 and 113) much increases 
the confusion by completely separating A. thoracica from A. fava, on 
the ground that the former has the penultimate joints of the antenne in 
the male distinctly longer than broad, and in the female scarcely, if at 
all, transverse ; it is obvious, therefore, that Mulsant’s A. thoracica cannot 
be the same as the insect which we ordinarily consider as the A. 
thoracica of Linné, and that it stands in fact in the genus Anaspis 
proper, and not in the sub-genus Wascpa of I’mery, in which the latter 
author places A. flava ; Emery (Essai Monographique sur les Mordellides, 
p. 21, L’Abeille, tome xiv.) refers the A. thoracica of Mulsant at all 
events in part to A. confusa, a new species of his own; this is very 
likely the true explanation of the difficulty, and as it is very probable 
that this species occurs in Britain (the localities given being Europe 
boréale et moyenne), it may perhaps be of service to append his 
description. 
(A. confusa, Emery (A. thoracica, Muls., Longipéd , p. 110 (ex parte). 
— A. lateralis, Thoms. Skand. Col. vi. p. 302, 3). 
Black, silky, with the head, thorax, base of antenne, and legs rufo- 
testaceous, posterior femora usually fuscescent; thorax not one and a 
half times broader than long; antenne with the joints gradually and 
slightly narrowed towards apex, with the penultimate joints feebly sub- 
conical in the male, and more distinctly so in the female. L. 23-3} 
mm. 
Male with the third segment of the abdomen produced behind, with 
the appendages approximate, and nearly straight at base, and slightly 
curved inwards at apex, passing beyond the apex of the abdomen, fourth 
segment small, with less conspicuous, depressed appendages, fifth seg- 
ment foveolate, incised at apex.) 
M. Emery is also of opinion that a portion of Mulsant’s A. thoracica 
may perhaps have to be referred to his A. Coste, a species of his sub- 
genus Nasipa, which closely resembles A. flava, but differs in having 
the fourth segment of the abdomen in the male furnished with 
appendages, which are longer than in any other species of Anaspis, 
and reach to the apex of the appendages of the third segment ;
