264. On Choleva angustata, Fabr., and its Varieties. — 

 The different forms of tliis species were first separated by 

 Kraatz, on the shape of the coxae in the male; Murray, how- 

 ever, in his very careful Monograph, has again united them 

 under one head. Characters drawn from these parts are con- 

 fessedly inconstant, but being, as they are in this case, accom- 

 panied by other slight but fixed differences, we cannot, I think, 

 refuse to admit them as species, though of a subordinate de- 

 gree of value to other species, or, as they have been termed 

 in Botany, cognate species. The general appearance is a 

 good deal alike in the four species, but the male characters 

 readily separate them : M. Brisout de Barneville (Gren. Cat. 

 Col. Fr. 8) has pointed these out with his usual aptitude, ft-om 

 which notice I extract the following diagnoses : — 



1. C. Sturmii, Bris. — Abdomen with segments 2 — 4 

 marked with a slight impression ; posterior coxae short, sim- 

 ple ; femora with a small tooth before the middle. I have 

 one specimen, from Mr. Janson's collection, taken near 

 London. 



2. C. angustata, Fah., Bris. — Abdomen with segments 3 — 5 

 deeply impressed ; coxae short, pointed, inner margin pro- 

 duced. Fern. — Elytra terminated with a short spine. 



3. C. cisteloides, Frohl., Kr. — Abdomen with segments 

 2 — 5 lightly impressed ; coxae short, like the preceding, but 

 produced into a curved spine on the inner margin. Fern. — 

 Elytra simple. 



4. C. intermedius, Kr., Bris. — Abdomen with segments 

 4 — 5 lightly impressed ; coxae long, gouge-shaped. Fern. — 

 Elytra simple. One specimen, from Mr. Janson's collection, 

 taken at Finchley. 



The males may be always known by the dilated anterior 

 tarsi and curved intermediate tibiae. The two other species 

 of the subgenus, C. agilis and C. spadicea, are unmistakeable, 

 the latter by its deep strong punctuation and simple coxae, 

 and the former by its singularly curved male tibiae, and 

 thorax widest at the base. — G. R. Crotch ; University Li-

265. Alomar ia fer rug in ea and other Coleoptera at Bird- 

 brook. — During a short visit at Birdbrook, in Essex, last 

 August, I was fortunate enough to capture fourteen speci- 

 mens of the very rare Atomaria ferruginea, which I think
