 crossed in the centre by two reddish-brown subangidated 

 stripes, the lower half of the area between which is pale 

 ferruginous ; two or three white-sj)eckled black spots in 

 an oblique series parallel to the anal half of the outer 

 margin, the latter slightly excavated ; thorax tinted with 

 lilacine ; undersurface pale fuliginous, the secondaries 

 whitish, excepting upon the costal and external borders ; 

 a nearly central transverse dusky line ; posterior half of 

 pectus and the venter sordid white : expanse of wings

The genus Rhesciplia should properly be placed next 

 to Teratocera and not in the Liv^acodidcB (compare 

 Trans. Ent. Soc. 1878, p. 72) ; the palpi are similar 

 in both genera, although more developed in R. servia and 

 R. obtusa (not in R. elegans). 



Walker's two genera Livinna and Leida, referred to 

 this group, are specifically identical, and are "^ E-phyr odes'' 

 scitilinta of the same author, and the male of " Thermesia''' 

 sigillata..

Probably the one example obtained by Dr. Trail is a 

 slight variety of Cramer's species ; anyway, it is too close

 to '' Hypcnaria''^ orphna of Hiibner, I- am satisfied that,
