174 THE CANADIAN ENTOMOLOGIST. 



Aegeria floridensis, n. s. 



$ . Seems to belong to a new structural group, for which I propose 

 the name Pyrrhotaenia. The antennae are heavy, lengthily pilose, brush- 

 like. The naked eyes are banded black and golden, narrowed superiorly. 

 The ocelli are large. The head is narrow, prominent ; palpi curved, long, 

 ascending, free from the front ; maxillae moderate. Anterior wings 

 scaled, very narrow, widening terminally at outer third, blackish violaceous. 

 The narrow portion of the wing is medially orange red, interrupted by 

 the ground color at beyond the disc. Beyond the interruption the inter- 

 spaces are orange red for a short space • the internal margin to terminal 

 third is narrowly streaked with orange red. Beneath largely shaded with 

 orange ; the violaceous terminal portion of the wing interspaceally rayed 

 with orange. Hind wings pellucid, with narrow orange costal border and 

 blackish fringes. Head covered with broad blackish violaceous scales 

 antennae violaceous. Palpi and collar orange. Legs violaceous, marked 

 with orange ; hind tibiae twice broadly banded with orange. Abdomen 

 blackish cyaneous, with a concolorous terminal tuft containing a few white 

 scales ; two terminal segments banded with orange, fourth from the tip 

 orange banded, this color extending beneath. 



Expanse of fore wing, 6 m, m. Total length of body, 9 m. m.

The discal dot is sometimes obsolete on the fore wings above.

Didasys, n. g. 



A form allied to the Cuban Burtia. The abdomen in the male pro- 

 vided with two lateral, elongate, pilose, blackish terminal tufts, one on each 

 side, arising from the genital pieces, which latter are prominent, exceeding the 

 anus, when closed forming a whitish JJ beneath, from the color of the 

 scales. The large ocelli are removed from the somewhat narrowed, naked 

 eyes. The plumose J antennae are thickly furnished with lengthy setose 

 pectinations. Palpi moderate, pointed, exceeding the front. Shape of 

 the wings as is usual in the group. The median fold of Cosmosoma is 

 absent.
