Stigma linear but somewhat thickened and readily distinguishable from the wing 

 border; sul)discoidal nervure distinct, originating from above the middle 

 of the discoidal nervure (859) Delomrpa Forster. 



17. Vertex concave; thorax compressed laterally (860) Dipiesta Forster. 



Vertex convex ; thorax not compressed laterally (861 ) AnpiloUi Forster. 



18. Second discoidal cell open; marginal cell closed before the apex of the wing. 



(862) Helerolexis Forstei-. 

 Se«'ond discoidal cell closed; marginal cell closed at the apex of the wing.

The insects falling in this subfaniih' have the same habits as the 

 Alysiintf and exhibit .scarcely any structural difference; the only 

 character ^et pointed out to separate them from the preceding being 

 the ditference of venation in the front wings. 



The Dacmisincti have only tvx> cuhital cells while the Al3^siill» have 

 tJiree, except in one or two cases where the iir.st transverse cubitus is 

 absent, so that the student must be careful not to place these in this 

 subfamily. In all genuine Dacnusines the Jii'st transverse cuhitiis is 

 al/ivays present . He must also bear in mind that there are no apterous 

 females in this group. 



Twenty -five genera have been recognized, separable as follows:
