transverse band and half-band. Under surface of posterior wings show¬ 
ing a discal dot and an irregular darker shaded median line. Antennae 
moderately short and stout with a basal tuft. Collar blackish ; thorax 
and tegulse greyish, ikbdomen stout, exceeding the posterior wings,

Resembles Raplila hijhris Htibner (H-S. Neue Schm., fig. 62 9 ) in 
size and appearance, but 1 think differs specifically by the ornamenta¬ 
tion of anterior and coloration of posterior wings. 
The genus Raphia, of which R. ahrupta is the only North Ame¬ 
rican species known to me, shows some affinity to the genus Diplitliera ; 
its position under the present family is in accordance with the classifi¬ 
cation of Dr. Herrich-Schaeffer. R. ahrupta is generically distinct 
from the species included under Raphia Walk.; and as I regard it as 
congeneric with R. hyhris Hiib. H-S., which I do not find in C. B. M.. 
I describe it under the present generic name which has been appar¬ 
ently misapplied by Mr. Walker. 
CYMATOPHORINA H-S. 
Lacinia expultrix Grote, Proc. Ent. Soc. Philad., Vol. II, p. 58. Plate 2, fig. 6 9 . 
Since naming this species as a variety of L. cy7natophoraides Gruen., 
I have had occasion to examine very many % 9 individuals of it in 
private collections, and my observations, as well as those on the larva 
(Proc. Ent. Soc. Philad., Yol. II, p. 134), induce me to regard this as 
a distinct and valid species, although confounded with L. cymatopho- 
roides, by Messrs. Gruenee and Walker, and as such it will retain the 
name I have given it as above. 
The genus Lacinia^'^ though not very'strongly distinct from Thyaty- 
Genus Molluscorum. I refer to M. Guenee’s opinion on the generic name 
Colocasia Ochs. ISToct. 1, ]). 39, and think it unnecessary to change the name I 
at first adopted.
