394 EXOTIC MICROLEPIDOPTERA. 



British Gcjiana, Bartica, from December to February {Parish); 

 twenty-two specimens. Tlie characteristic stalking of veins 8 and 

 9 is invariable and strongly pronounced, but cannot be esteemed a 

 ground for generic separation, the specific relationship io pseudo- 

 chyta being so extremely close in every respect. This suggests 

 that the genus Mothonica Wals., only distinguished from Slenoma 

 by this same character, is probably not well grounded ; on the 

 artificial system of Busck and Walsingham this species would be 

 placed in Motlionica and the preceding in Stenoma, twenty 

 characters being disregarded for the sake of one.
