TERMINI. jO; 



They are to be found also in many other Hyme- 

 nopterous insects. 



Metathorax. In this class this is so conspicuous 

 a part, that I wonder no author has taken notice of 

 it. It is separated from the thorax and scutellum 

 by sutureSj and, in some instances, might perhaps, 

 supply a good generic character. 



Pleura. As the word cost a, has been usually 

 employed to signify the strong marginal ner\^e of 

 the superior wings, I have fixed upon this to de* 

 note the sides of the truncus. 



Sternum. In the genera treated of in this work, 

 this part is immersed in the breast, and is not to 

 ]be discovered without taking off the fore legs. 



Squamula. Linneus in his descriptions notices 

 the part intended by this term, sometimes simply 

 as ^' punctum ante alas," and at others as "punc- 

 ium callosum ante alas." It is a corneous concavo- 

 convex scale under which the base of the superior 

 wings plays. 



Anastomosis. The term by which this part is 

 denoted, in the Fundamenta EntomologicP, is siig- 

 ma; but as this is also employed to signify a parr 

 ticular spot in the wings of some Phalicme, I 

 thought it best to alter the term, and adopt one 

 'which I have seen used, I forget by whom, to de- 

 note this part, and which seems with more strict 

 propriety applicable to it. Linneus, indeed, him* 

 ^elf does npt adliere to his own term^ using often 



punctunHf
