paste in each of them. She sometimes bores three canals in the 
same piece of wood. 
They are peculiar to warm climates *. 
The labial palpi of the other Apiariz are in the form of squamous 
sete; the two first joints, compared with the two last, are very large, 
compressed, scaly, and have a membranous or transparent margin. 
The maxillary palpi are always very short, and frequently consist of 
less than six joints. The labrum, in a great number, is elongated 
and inclined on the mandibles, sometimes forming a long square and 
sometimes an elongated triangle. 
The Apiarie, which in our work on the natural families of the 
animal kingdom we have collectively designated by the same of Dasy- 
gastre, are remarkable—as intimated by that name—for the numer- 
ous, short, crowded hairs, forming a silky brush, that almost always + 
covers the abdomen of the females. ‘The labrum is as long as it is 
wide or longer, and square. The mandibles of the females are 
strong, incisive, triangular and dentated. The paraglosse are al- 
ways very short, squamous, and pointed at the extremity. 
Of all the subgenera of this little group, that which appears to us 
to approximate most closely to the Xylocope, and which alone pre- 
sents maxillary palpi consisting of six joints, and wings furnished 
with three complete cubital cells, is the 
Crratina, Lat. Spin. Jur.—Meeitxa, Prosopis, fab. 
The body is narrow and oblong; the antenne are inserted in little 
fossulze, and>terminated almost in an elongated club; the mandibles 
are sulcated and tridentated at the extremity; the abdomen ap- 
proaches to an oval, and is destitute of a silky brush. The labrum 
is proportionally shorter than in the following subgenera, where it 
forms an elongated quadrilateral. According to the curious observa- 
tions of M. Maximilian Spinola—Ann.du Mus. d’Hist. Nat.—the 
habits of the females are the same as these of the Xylocope tf. 
All the remaining Dasygastree have four joints at most in their 
maxillary palpi, and two complete cubital cells. 
We first remark those species in which the under part of the ab- 
domen is evidently furnished with a silky brush. 
Curxostroma, Lat., 
Where the body is elongated, and almost cylindrical; the mandi- 
bles project, are narrow, arcuated, and forked or emarginated at the 
end; the maxillary palpi are triarticulated §.

further examined it, we refer the genus Lestis of MM. Lepeletier and_ Serville—

+ The Ceratinee, Stelides and Ceelioxydes, although destitute of a ventral scopa, 
should make part of this group, on account of the form of the labrum and mandi- 
bles, and other general characters.
