15. TlGRIDOPTERA, HS. 



Face with tolerably appressed scales. Tongue developed. Palpi 

 moderate, ascending, shortly rough-scaled, terminal joint short. 

 (Antennas in £ probably ciliated.) Thorax not crested, glabrous 

 beneath. Femora glabrous. Forewings (in £ probably with 

 fovea) ; 10 rising out of 11, running into 9. Hindwings normal. 



The characters of the £ are still unknown, and possibly they 

 may present additional peculiarities. The genus is however 

 distinct enough as it stands, and is most allied to the Palasarctic 

 genus Abraxas.
