4§ INTRODUCTORY REMARKS. 



tions, but the sides of the abdomen are always 

 crenate, its eyes are lateral and oval, and its anten- 

 nae Subclavate. No genus is more evidently dis- 

 tinct from all others than Chrysis. The antennae 

 are spiral, and, excluding the radicle and scapus, 

 fusiform. Anus dentatiis, ought to be thrown out 

 of the Artificial Character, as many species want 

 it, but it would form a good characteristic for a 

 family. The tongue of these insects is emargi- 

 nate(/). The Linnean character of Vespa is very 

 good, but instead of Os maxilHs absque prohoscide, 

 Lingua quadriloha ought to be prefixed. This 

 circumstance, in conjunction with Alee plicatcCy 

 distinguishes this from every other genus. Masaris 

 may be known by its reniform eyes, subclavate 

 antennae, wings not plicate, and body linear and 

 very narrow. Tiphia, by which I understand 

 T.femorata, Fab. and its congeners, has fusiform 

 anterior antennae, and a very short obtuse tongue. 

 The character of Formica requires some alteration, 

 for the squamula, as De Geer has well observed, is 

 the character of a family and not of a genus (m) ; 

 this, to include all, might be altered to abdominis 

 petiolo nodoso. I know too little of the genus Mu- 

 tilla to say much concerning it : but pubescence, 

 I think, ought, if possible, to be excluded from its 

 Artificial Character, and the apterous Ichneumons 

 should be omitted. The antennae of the few that 

 I am acquainted with are like those of Chrysis.
