52 Mr. J. O. Westwood on the 
ceeding authors, this insect is regarded as one of the Pselaphide, 
belonging to Leach’s genus Bryazis, whilst Gyllenhal’s (Ins. Suec. 
4, 232) description and reference assign it to the T'yrus mucronatus 
of Aubé; and to add to the confusion, Panzer figures a red 
species of Euplectus with a black head, with the same name and 
reference, although Linnzeus expressly says, “ totus ater glaber, 
exceptis elytris sanguineis.” The Linnzean specimen, however, 
belongs to the sub-family Aleocharides and genus Aleochara, being 
closely allied to 4. fuscipes. Mr. Kirby, in his manuscripts upon 
this family, communicated to Mr. Stephens and incorporated by 
him in his catalogue and illustrations, had noticed this cirecum- 
stance, and restored the specific name to the species, under which 
it is described by Mr. Stephens (Ill. Mand. 5, p.160). It appears 
to be identical with the small specimens of 4/. mitis, Grav., men- 
tioned by Erichson, (Gen. et Sp. Staph. i. 163,) as probably 
identical with the 4/. crassicornis of Boisduval and Lacordaire, or 
with the 41. rufipennis of Erichson (Er. cit. p. 162, which is how- 
ever distinct from the rufipennis of Kirby and Stephens). I 
possess a specimen of this insect from Mr. Haworth’s Cabinet, 
which had been compared by Mr. Kirby himself with the Lin- 
nan specimen of Sp. sanguineus, and to which is also attached 
the name 41. lugens, G., as asynonym. Mr. Stephens has also 
given that species as belonging to the same group of Aleochara 
as the Al. fuscipes and sanguinea. Dr. Erichson, having intro- 
duced Al. lugens into his genus Myrmedonia, evidently considers 
that Stephens and Kirby have erred in this respect; the maxille 
of my specimen of sanguinea, as I find on dissection, agree how- 
ever with those of A/. fuscipes, whereas the maxillee of Myrmedonia 
are very differently formed (Erich. pl. 3, fig. 21). 
Sp. 20. Staph. caraboides, Linn., belongs to the genus Lesteva, 
Latr., and subgenus Anthophagus (as restricted by Dr. Erichson), 
There are two closely allied species which have been confused in 
their synonymes, namely, 4. caraboides and A. testaceus. By 
Gravenhorst the species with a subcordate thorax is regarded as 
the St. caraboides, whilst that with a quadrate head is named 
A. testaceus. Messrs. Boisduval and Lacordaire, in the Faune 
Entomologique de Paris, have transposed these names; but Dr. 
Erichson has restored them, and with propriety, the thorax of 
the Linnzean specimen being evidently subcordate. The head 
can, however, scarcely be termed piceous, although considerably 
darker coloured than the thorax, which is bright testaceous; the 
elytra are paler, and the basal joint of the antennz is paler than 
the following joints.
