Dohrn (Stett. ent. Zeit. 1865, p. 61) describes a peculiar vaiiety of JBembi- 
dium eques from Naples, in -which the elytra are uniformly yellow, with a 
scarcely perceptible obscurity at the apex.

DyTISCIDiE. 
Altum has published (Stett. ent. Zeit. 1865, pp. 346-362 and 
398-402) a detailed description of the species of the genus 
Dytiscus found in the vicinity of Munster, -with especial refer- 
ence to the sulcation of the elytra in the females and to some 
cases of abnormal structure and hermaphroditism observed by 
him in those insects. He describes the general character of the 
sulcation of the elytra, and states that the furrows vary both in 
number and distribution. His general results may be summed 
up as follows : —

Altum describes the habits of D. latissimus, mentions his having taken a 
latissimus c? in copulation with dimidiatus $ , and gives a detailed descrip- 
tion of an hermaphrodite of the former species. He also describes some 
curious malformations of the tarsi in D. marginalise and indicates the cha- 
racters of the probable larvfe of D. drcumjlexus and B. dimidiatus, 
ScHiODTE (Naturh. Tidsskr. 3rd ser. yol. hi. pp. 154-161)

of the JDytiscid(Bj and describes those of the following species : —
