sexes of one of the species from larvae thus constructed; thus dis- 
proving Mr. Shuckard’s suggestion, that the female larva will neces- 
sarily have one segment less than those of the male, as in the imago. 
(Trans. of Burmeister, p. 35.; and Mag. Nat. Hist. Sept. 1837. See 
my memoir “ On the Apod Larvee of the Hymenoptera, with reference 
to the Segmental Theory of Annulose Animals,” in Zrans. Entomol. 
Soe. vol.ii. p.121.) Inthe same Transactions (vol.i. p. 78.) I have also 
published some notes upon the habits of Odynerus antilope, which 
lines its cells with mud, of which it carries small round pellets into its 
burrow, under the breast. It employs the green caterpillars of a 
Crambus? for the food of its young. Mr. Ingpen exhibited to the 
Entomological Society (August 4, 1834) the nest of Odynerus qua- 
dratus, which had been discovered between the folds of a piece of 
paper which had fallen behind some books. It was nearly six inches 
long and one wide, and had several openings to the cells, through 
which the insects, on arriving at the perfect state, had escaped; it ap- 
peared to be composed of dried mud. 
H. (in Mag. Nat. Hist. No. 25.) describes some larvee found in the 
healing of a book, apparently those of an Odynerus. Mr. Curtis also 
figures a species (O. parietinus), the cells of which were formed on the 
top of a book. 
Bouché states that Od. parietum stores up flies, &c., as well as the 
caterpillars of Tortrices (Vaturg. der Ins. p. 179.). 
M. L. Dufour has recently communicated a series of interesting 
observations upon the economy of several species of Odynerus to the 
Académie des Sciences, but they have not yet been published. (See 
Comptes Rendus, No. 10. Sept. 1838 ; and Annals Nat. Hist. No. 8. 
Oct. 1838.) I am indebted to Mr. F. Smith for specimens of Ody- 
nerus levipes Shk., and its nest, first described by Mr. Shuckard 
(Mag. Nat. Hist. Sept. 1837). The cells are formed of agglutinated 
sand, lining the cavity of a dead stick of the common bramble, from 
which the pith had been excavated, probably by Osmia leucomelana, 
and placed end to end. Mr. Sells has found twenty-five small Lepi- 
dopterous larve in the nest of an Odynerus; and Mr. Saunders as 
many as seventy-five in the nest of Epipone spinipes. Mr. Waterhouse 
has also discovered Lepidopterous and Chrysomelideous larvee in the cell 
of an Odynerus ( 7rans. Ent. Soe. vol. ii. p. xviii.) : I have also observed 
and captured many specimens of O. crassicornis #z. near Paris, 
which were always loaded with the Jarvee of Chrysomela Populi, which
