Division II1.* 
HYMENOPTERA ACULEATA. Lat. 
Antenne with thirteen joints in the males and twelve in the 
females. Wings always having nervures and presenting 
the various kinds of ordinary cells. Abdomen always 
petiolated and consisting of seven segments in the males 
and six in the females, and containing in the latter a sharp 
sting concealed within the anus. Their larve are apodes, 
and are supplied by their parent with provisions for the 
time they remain in that state, or are else fed daily by 
neuters, (females whose ovaries are abortive,) or by the 
females; in the two latter cases they are united in 
societies. Some are parasitic. 
Tribe I. 
HETEROGYNA. Lat. 
These Hymenoptera are generally burrowers or live upon 
the ground, sometimes assembled in societies, which are 
temporary in these latitudes. The antenne are geniculated. 
* The Hymenoptera are separated into two divisions. The first containing 
the Terebrantia, and the second the Aculeata ; the latter are subdivided into four 
tribes, viz. 1. the Heterogyna; 2. the Fossores; 3. the Diploptera ; and 4. the 
Mellifera. Itis only of the second family of the first tribe of the Aculeata and 
the whole second tribe that the following pages treat.
