276 VESPA, VESPERTILIO. 
vulgaris, (common wasp,) thorax black with an 
interrupted yellow line each side ; scutel with 
four yellow spots ; abdomen yellow, the incis- 
ures with distinct black dots. Live in large 
societies, and construct a pendent cone with 
wuody fibres in an incipient state of decay. The 
fibres are manufactured into thin concentric 
membranes, laid over each other at a distance 
sufficient to leave a passage between them. ‘The 
combs are placed in the base of the cone. 
Remarks. Five of the genera abdopted by 
Aatreille are the sections of this genus. ‘Thus: 
Sec. B. Lip ovate, as long as the jaw, is the 
Me tiinus. §& species. 
Sec. ©. Lip compressed, rounded, longer than 
the jaw, is the PuiLaANTuus. 14 species. 
See. D. Lip short, horny; is the Crasro, 56 
species. 
Sec. EK. Tongue bifid, retractile, isthe Masanis. 
2 species. 
Sec. F. Tongue inflected, five-cleft, is the Bum- 
BEX. 17 species | 
Each of these might be subdivided again and 
again; and so might every genus in every depart- 
ment of natural history, if it contains more than 
one species.
