1871.) a 
Occurrence in Britain of Compsochilus palpalis, Hr.; a genus and species of Ovy- 
telides new to our list.—I have recently taken a single example of this interesting 
addition to our Brachelytrous Fauna, by sweeping on the sides of a ditch near Tun- 
bridge. In facies the insect strongly resembles Acrognathus, in which genus it was 
placed by Erichson ; but its much smaller size, 1$ lin. (Engl.), at once readily dis- 
tinguishes it from A. mandibularis.—T. V. Wotuaston, Dry Hill, Tunbridge, 16th 
June, 1871. 
Notes on some recently described species of Oxytelus allied to O. depressus.—Herr 
Czwalina, in vol. xiv of the Berlin. Entom. Zeitschr, p. 419, et seqg., has recently de- 
scribed three new species of the depressus group (in which the head, thorax, and elytra 
are very thickly and finely longitudinally striate), taken near Kénigsberg in company 
with that common species; thus increasing Pandellé’s list (in Grenier’s Cat. pt. 2) 
of that group to the number of twelve, and suggesting a doubt whether Gravenhorst 
redivivus would know his own property.* 
Czwalina thus tabulates his new species and their allies :—

The natural sequence of these species is stated by the author to be thus: 
speculifrons, transversalis, Saulcyi, depressus, hamatus, affinis, tetratoma. 
O. transversalis (p. 419) is described as equalling large depressus in length, but 
rather broader, of a deeper black, with pitchy legs; the base of the tibize rather 
yellow, but the claw-joint dark. Its antennz are somewhat stouter at the apex, 
and abdomen rather more strongly punctured above, the sixth segment beneath in 
the g having in the middle two longish and not very approximated tubercles, with 
a fine granule between each of them and the side margin. The hind margin of the 
seventh segment in the same sex is widely and not very shallowly emarginate in 
the middle, and has a longitudinal callosity very near each side margin. It is 
* The description of 0. tetracarinatus, Block, published in 1798, must have been much in ad- 
vance of its time ; as that insect is identified with the subsequent 0. depressus of Gravenhorst in 
V. Harold’s Uol. Heft, vi, p. 101, in the face of the other closely allied eleven species now 
known.—E. C. R.
