 small apical tuft on upper-surface; terminal joint minute. 

 Thorax and abdomen without crests. Posterior tibiae some- 

 what hairy. Forewings with 8, 9, 10 stalked from areole.

23. Gen. Diplothecta, nov. (SiTrXoOrjKTo^, twice sharpened). 



Frons with a conical projection. Palpi long, porrect; 

 second joint very long, thickened with rougli scales above and 

 beneath, greatly expanded towards apex ; terminal joint 

 moderate, stout, obtuse, slightly depressed. Antennae of male 

 simple, minutely ciliated, with a longer bristle on each seg- 

 ment. Thorax and abdomen not crested. Forewings with 

 2 from |, 3, 4, 5 equidistant from near angle, areole present 

 but small, 7, 8, 9 stalked from areole. Hindwings with 2 

 from |, 3, 4, 5 equidistant from near angle, 6, 7, connate, 

 8 anastomosing with cell from J to middle. 



Allied to Soph f ft, Wlk., with which it agrees in the 

 •conical frons, shape of forewings, and small areole ; but differs 

 in the longer, porrect, much-dilated palpi, and in the long 

 anastomosis of vein 8 of hindwings.

 fuscous dots ; a line of minute white dots from costa near 

 apex to tornus : a submarginal series of fuscous dots; an
