second and third median branches separated at their origins, 

 instead of being emitted from the same point. Type T. veneris.

 Type B.M. 



There are one or two species somewhat resembling this de- 

 scribed from South America — IT. Hcitiirniaria, Herr.-Sch., JJ.plati- 

 nata, Gruen., and IT. qiiadrifilata, Felder ; but I have had no 

 opportunity of examining them, and the markings on their 

 secondaries incline me to refer them provisionally to Syssodes. 



GoJSfOETHus, gen. nov. (Plate IX. figs. 9, 10.) 



Differs from Urapteryx in the form of the wings — the 

 primaries having an acute apex and straight outer margin ; the 

 secondaries with rectangular outer margin, the angle being 

 acutely produced, but not preceded by a short angle as in the 

 two foregoing genera ; discocellular of secondaries almost 

 straight and transverse. Type G. flavifimibria. The typical 

 species is wonderfully like Micronia excepting in neuration.

 B.M. 



Urapteryx tesserata and U. hreviaria of Guenee and Hlibner 

 should probably be placed here, so far as I can judge from 

 Hiibner's figure. 



RiPULA, Guenee. (Plate IX. figs. 17, 18.) 



Differs from Gonorthus, to which it is nearly allied, in its less 

 strongly pectinated antennae in the male, the eubangulated 

 outer margin of the primaries, and narrower discoidal cell with 

 inangled discocellular veinlet to the secondaries. Type B. maho- 

 metaria.
