of the Conops in a box in which he had placed some of the Bombi ; 
and Messrs. Lachat and Audouin have published an interesting me- 
moir upon an apod larva found in the intestines of Bombus lapidarius 
Linn (Apis), which Latreille attributed to this species of Conops. 
This larva was very soft, whitish, 11-jointed, with a long neck and a 
mouth armed with lips and hooks, and an anus vertically slit, and two 
lateral elevated plates supporting the two spiracles. (Mém. de la Soe. 
d Hist, Nat. de Paris, tom. i.) M. Robineau Desvoidy has also ob- 
served a species of Conops pursuing a Bombus with great patience, and 
flying on it several times (Comptes Rendus de [ Acad. No. 23. 1836), 
as has also M. Dufour, who, moreover, possesses a Bombus terrestris, 
from the anal part of which a Conops rufipes is dependent, the swollen 
extremity of the abdomen of the latter being retained within the 
former. (Ann. Se. Nat. Jan. 1837.) Ihave also frequently observed 
Myopa atra flying about sand-banks in which were the burrows of 
various bees. Latreille has united to this family several small genera, 
which Meigen formed into a distinct family, Stomoxide, having nearly 
the appearance of the common fly, to which they are allied in the 
structure of the antennae, abdomen, and wings; the proboscis is, how- 
ever, porrected and elbowed once or twice. Nitzsch has described a 
minute insect, which he refers to this family, under the name of Carnus 
hemipterus, of the size of a flea, with minute rudiments of wings, which 
is parasitic on the birds of the genus Sturnus. (Germar’s Mag. No. 3. 
p- 306.) 
The family Muscip# *, corresponding with a portion only of the 
genus Musca of Linnzeus, or with that genus as restricted by Fabricius 
(fig. 131. 13. Echinomyia grossa), is distinguished from all the other
