sides at a disfanoc from the hind angles. Tlie thorax is elongate, longer than broad, 

 though only a little narrower than the elytra, (he sides are much narrowed towards 

 the front (so that the front part of the thorax forms a sort of short neck), and they 

 project in the middle in the form of a prominent acute tubercle, behind which the 

 thorax is abruptly nari'owed ; along the middle is a deep channel, and at each side 

 behind the lateral angle is a large deep impression. The elytra are but little longer 

 than the thorax, a little narrowed at the shoulders ; each has a deeply impressed 

 sutural stria, and the humeral angle is prominent, and within this the surface is 

 depressed, and the inner margin of the depression extends towards the extremity as 

 a kind of plica. The first segment of the hind body is in the middle close behind 

 the extremity of the elytra transversely impressed, and the impression is filled with 

 fine hairs. The legs are moderately long, the tarsi rather more than half the length 

 of the tibiae. 



A single example of this very curious Pselaphid was sent me by 

 that most successful collector the late E. Haymond, from Corsica, 

 under the name of Trichonyx aherrans ; the species, however, does 

 not appear (though this was five or six years ago) to have yet found 

 a dcscriber.

JVote on a curious race of Ilarpalus latus, L. — I am indebted to Mr. George 

 Lewis for a ? example of a most interesting variety (or race) of the above-mentioned 

 common insect, apparently hitherto unnoticed, and which is so conspicuously different 

 from the type, that I propose to give it a name (metallescens), especially as some 

 five or six of it were taken, all (as I am informed) exactly alike. These specimens 

 were found during the past summer by a relative of Mr. Lewis's, at Folkestone. The 

 individual in my possession is hard and mature : its legs are of a brighter yellow 

 than usual ; the whole upper surface is of a silky greenish tone, the thorax being 

 especially ^recM at the hinder angles ; the thorax itself seems scarcely so transverse 

 as usual, being appreciably contracted behind, and having its posterior angles not 

 nearly so rounded off as in ordinary examples ; the punctuation at its base is almost 

 obsolete and confined to the fovere, and the fovea; themselves are much less conspicuous.

Note on a variety of Liodes humeralis. — I am also indebted to Mr. Lewis for a 

 specimen of the var. glohosa, Payk., of this common species, not hitherto recorded 

 as British, though the other described var. (entirely rufo-castaneous, with lighter 

 iiulications of the usual shoulder spot), clavipes, Hbst., is, accoi'ding to Erichson, 

 represented by Leiodes armata, Steph. (which, teste Wat. C&t., is? Anisotomartigosa, 

 in Steph. Coll.). In the var. glohosa, the disc of the thorax is more or less black, 

 and the luiraeral spots are eo confluent as to invade the whole elytra except the apex, 

 •which is dark ; there is also a trace of dark colour along the suture. The insect is 

 quite hard and mature, but the " var." clavipes seems probably nothing but an 

 immature individual. — Id. •
