Lathrobium is closely allied to Gyrohypnus, from which it is 
distinguished by the much shorter basal joint of the antennae, 
and the dilated anterior tarsi ; from Cryptobium * it is separated 
by its antennae, which are not geniculated. The following are 
British species : 
1 . quadratum Payk. — pilosum Grav. ? 
Under stones, moss, moist banks, and in damp places at 
Battersea, &c. 
l b . terminatum Grav. — Curt. Brit. Ent.pl. 650. 
Probably only a var. of L. quadratum : taken by the late 
Mr. Blunt, and Mr. A. Matthews finds it at Weston-on- the 
green. 
2. brunnipes Fab. — dentatus Mars. 
Under moss, in winter, near Yarmouth, Mr. Paget ; and 
under stones, near Swansea, Mr. Dillwyn. 
2 b . atriceps Kirb. In Yorkshire and near London. 
3. elongatum Linn. — Don. v. 16. pi. 513. f. 3. — Panz. 9. 12. 
Common everywhere under stones, moss, dung, putrid ve- 
getables, See. 
4. fulvipenne Fab. Panzer’s Plate 1 7, No. 23, referred to by 
Mr. Stephens, is a Pyralis, and the P.Julvipennis, 27 5 24, 
of Panzer, is apparently a Gyrohypnus. 
5. rufipenne Gyl. v. 3. p. 704. 
5 b . ochraceum Mars. MSS. — Step. 
6. punctato-striatum Kirb. The Pcederus testaceus of Olivier, 
referred by Mr. Stephens to this species, evidently belongs 
to another genus, the shape of the thorax being very differ- 
ent. 
6 b . punctulatum Mannerheim. 
7. multipunctatum Grav. — axillare Zieg. 
8. lineare Grav. — Gyll. v. 2. 370. 6. 
Common under stones, and amongst rejectamenta left by 
floods. 
9. longulum Grav.— minutum Dej. 
10. fovulum Step. 
11. nanum Step. 
12. erythrocephalum Step. 
The Plant is Milium (Gastridium Beauv.) lendigerum , Pa- 
nick Millet-grass, from Ryde in the Isle of Wight, communi- 
cated by Dr. Bromfield. 
* Genus 201 a . of the 2nd edition of the Guide, which is just published.
