which she deposits a portion of honey, of the colour and con- 
sistence of a black and oily grease; it has a narcotic odour. 
Common in the environs of Paris. 
In the others the ligula is straight, or shightly bent under at its 
extremity. Such are SpHecopes *, Haricrus},and Nomi, Lat.} 
Here also the maxille are more strongly geniculate than in the 
Andrene. ‘There are always three closed cubital cells. 
The male Sphecodes have knotted antennz ; their ligula, as well as 
that of the females, is almost straight, and its divisions are nearly 
equal in length; that in the middle is much longer in Halictus and 
Nomia. ‘The female Hailcti have a longitudinal cleft at the poste- 
rior extremity of the abdomen. ‘The thighs and tibiz are inflated or 
dilated in the male Nomie. 
The second section of the Anthophila, that of the Aprarra, Lat., 
comprises those species in which the mediate division of the ligula is 
at least as long as the mentum or its tubular shield, and is filiform 
or setaceous. The maxille and labium are much elongated, and 
form a sort of proboscis which, when at rest, is geniculate and bent 
under. 
The two first joints of the labial palpi most frequently resemble a 
squamous and compressed seta that embraces the sides of the ligula; 
the two others are very small; the third is generally inserted near 
the exterior extremity of the preceding one, which terminates in a 
point. 
The Apiariz either live solitarily or form communities. 
The former never consist of more than the ordinary number of 
individuals, and each female provides singly for her young. The 
posterior legs of their females are neither furnished witha brush on 
the inner side of the first joint of the tarsi, nor with a particular de- 
pression on the exterior side of their tibize; this side, as well as the 
same of the first joint of the tarsi, is most commonly and densely 
covered with hairs. 
A first division of these solitary Bees is composed of those species 
in which the second joint of the posterior tarsi of the females is in- 
serted in the middle of the extremity of the preceding one; the ex- 
terior and terminal angle of the latter does not appear to be dilated or 
to project more than in the interior, in the following subgenera. 
We may also abstract from this group certain species—Andre- 
* Lat., Gener. Crust. et Insect., 1V, 150. MM. Lepeletier and Serville have 
formed a new genus—Encyc. Méthod.—allied to Sphecodes, under the donomination 
of RuaTtTHyMus—formerly Colaw—but differing from it in the projection of the scu- 
tellum, and in the third cubital cell, which reccives the two recurrent nervures. Be- 
sides this, the hooks of the tarsi are entire. They quote but one species, which 
is found at Cayenne.

The tenth volume of the part relative to Insects, of this important work, also con- 
tains several other articles by MM. Lepeletier and Serville, respecting the Insects of 
this family. We would particularly notice that of the Furasites. Some of them 
go to establish new genera, but as we have not been able to compare their characters 
with sufficient care, we are compelled to omit or barely mention them.
