2. Atalanta wrata, n.sp. (Tab. V. figg. 11, 11 a.) 
Head and thorax above very dark olivaceous ; abdomen above fuscous, sometimes clothed with greyish tomen- 
tosity, and always with a long greyish-white waxy anal appendage. Body beneath and the legs dark 
olivaceous. Tegmina with the basal two thirds bronzy-green spotted with ochraceous, and separated 
from the apical area (which is bronzy in hue) by a transverse greyish fascia. Wings pale greyish-sub- 
hyaline, the base very pale greenish, the apex fuscous. 
Exp. tegm. 46 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
I have not attempted to give the length of the body, as the development of the 
waxy secretion prevents such a measurement being taken with any degree of accuracy, 
and this remark applies also to the following species. 
3. Atalanta violacea. (Tab. V. figg. 13, 13a.) 
Head and thorax above very dark violaceous. Abdomen above apparently of the same colour, but clothed with 
greyish tomentosity, and with a long waxy greyish-white anal appendage. Body beneath and the legs 
dark violaceous, but much covered with greyish tomentosity. Tegmina pale violaceous, the basal two 
thirds spotted with dark violaceous, and separated from the apical area by a dark violaceous transverse 
fascia; the apical area violaceous-brown, pale violaceous near the transverse fascia. Wings pale 
hyaline, the apical margin and the venation fuscous. 
Exp. tegm. 45 to 54 millim. 
Hab. GuateMaLa, Coban and Sabo in Vera Paz (Champion). 
Mr. Champion found this species resting on coffee-plants. 
PTERODICTYA. 
Pterodictya, Burmeister, Handb. Ent. ii. 1, p. 155. 1 (1839); Stal, Hem. Afr. iv. p. 139 (1866) ; 
Stett. ent. Zeit. xxi. p. 288 (1870). 
This is one of the most easily recognized genera in the whole group, the talc-like 
and reticulated tegmina being very distinct and peculiar. Only one species is at 
present recorded.
