Sepsides. 
Van der Wulp (Tijdsclir. voor Ent. pp. 120-143) has some observations on 
the species of Sepsis and the allied genera, and on the distinctions of the 
genera of this group of Muscidce^ with especial reference to the forms met 
with in Holland. 
New genera : — 
Acrometopia^ Lioy, Atti 1st. Yen. 3* ser. tom. ix. p. 1088 {Sepsis, auct. 
ex parte). Forehead with a pointed process ; anterior coxm in cf with a tooth ; 
wings with two approximate transverse veins and a black spot at the extre- 
mity. Sp. Sepsis cm'nuta (Meig.). 
Bcggiata, Lioy, 1. c. p. 1088. Allied to preceding; forehead not projecting ; 
third joint of posterior tarsi in d with a tuft of hairs beneath ; wings as in 
preceding. Sp. Sepsis harhipcs (Meig.) 
New species :~ 
Tliemira denthnana, Van der Wulp (Tijdschr. voor Ent. vii. p. 135, pi. 8.

Oscinides. 
Cohn records the occurrence of a species of CJdorops in the wheat-fields of 
Silesia, in 1864, which in some places destroyed as much as 90 per cent, of 
the crop. This fly is double-brooded — the first brood appearing in June, the 
second early in August. Cohn describes the insect and the nature of its 
ravages, but states that it agrees with none of Meigen’s species. It is very 
nearly allied to C. lineata. (Stett. ent. Zeit. 1864, pp. 413-417.) 
Frauenfeld records the occurrence, near a destroyed egg of Lixus turhatus 
(Gyll.), of a Dipterous puparium, from which a small fly, supposed to be
