^08 TERMINI. 



punctnm marginale, and sometimes macula margia 

 nalis instead of it. 



Hamuli. These are very minute hooks or 

 crotchets, discoverable under a good magnifier on 

 the inferior wings of many Hymenopterous insects^ 

 by means of which they are kept steady in flying. 

 They have been noticed by no author, that I have 

 an opportunity of consulting, except De Geer, and 

 he observed them in no genus besides Formica (k), 

 in which they are not near so conspicuous as in 

 Jpis. 



u/ipophysis. I find this term used by Schrank

Flocculus. This woolly lock at the base of the 

 posterior legs of one family of Meliita I find noti«*

Velum. This membrane, attached to the Spini^
