HYMENOPTERA. 141 
The type of the first, that of the Masaripzs, Lat., is the 
genus 
Masaris, Fab. 
The antennz at the first glance seem to be composed of but eight 
joints, the eighth, with the following ones, forming an almost 
indistinctly articulated club, rounded or very obtuse at the end. 
The ligula is terminated by two threads which can be withdrawn 
into a tube formed by its base. There are but two complete cubital 
cells in the superior wings. The middle of the anterior margin of 
the clypeus is emarginated and receives the labrum in the notch. 
Masaris, proper. 
Where the antenne are rather longer than the head and thorax, 
and have their first joint elongated, and the eighth forming an ob- 
conical club rounded at the end. The abdomen is long(1). 
Cxieonires, Lat.—Masaris, Fab. Jur. 
Where the antenne are hardly longer than the head, and have 
their two first joints much shorter than the third, and the eighth and 
following ones forming an almost globular body. The abdomen is 
hardly longer than the thorax(2). 
A species figured in the great work on Egypt appears to form an 
intermediate subgenus. 
- The second tribe of the Diploptera, that of the Vesparta, 
is composed of the genus 
Vespa, Lin. 
Where the antenne always present thirteen distinct joints in the 
males and terminate in an elongated, pointed, and sometimes—in 
the males—hooked extremity: they are always geniculate, at least 
in the females and neuters. The ligula is sometimes divided into 
four plumose filaments, and sometimes bilobate with four glandular 
points at the end, one on each lateral lobe, and the remaining two on
