brown, with a golden gloss ; antennas much shorter than the wings, black, with the base thickened, the extreme 

 apex extremely slender and white. Taken by Mr. Dale in Dorsetshire. Described from Mr. Bentley'a cabinet. 



PORRECTARIA, Haworth. 

 The palpi are considerably longer than the head, much porrected, considerably divaricating, with the terminal 

 joint half as long as the preceding, very slender and attenuated to the tip ; the antennae are long and slender, 

 with the basal joint dilated and elongated ; the fore wings are long, narrow, lanceolated, and rather hooked at 

 the tip, with very long fringe ; the hind wings are also deeply fringed, they are deflexed when at rest. The 

 caterpillars reside in singular moveable cases, of their own formation, within which they assume the pupa state, 

 first attaching the mouth of the case to the plant, and making their exit out of the opposite end. The perfect 

 insects rest with the antennae stretched out and united in a straight line, like some of the PhryganeidEe.
