extending towards tlio outer angle, where it becomes attenuated to a fine line ; it bears several sliglit cloudings, 

 forming a subapical flexuous striga, and a minute row of dark dots on tlie margin ; the hind wings are pale 

 gray-brown. The caterpillar is pale buff-coloured, with a dark dorsal line, and several pale reddish lateral ones.

SvNONYME. — J'hytometra alhidlt'iiiea^ Iluwoiih ; Stephens ; Wood, Ind. Eut. pi. 17, fig. 427. 



Tills species measures 1 inch in expanse, and is very closely allied to the preceding insect, of which it is 



regarded as a probable variety by Curtis and Stephens, with the markings suffused, the pale patch at the anal 



angle of the fore wings being obliterated, and the subapical pale flexuous striga very rudimcntal. It is captured in 



company with the preceding species, according to Mr. Stejihens, but very rarely.

HYDRELIA, Gu^nee. ERASTRIA, i-., Curtis, Stephens. 



This genus differs from the preceding by having the abdomen not tufted along the back ; the palpi are 



elevated, with the terminal joint short and scarcely visible; the wings with strongly-marked stripes, on which 



the striga. are obliterated. The caterpillars are of bright colours, with the line above the spiracles only d.stn,ct ; 



they have fourteen feet, but the fifth pair is short and unfitted for walking. They feed upon plants ,n da„,p
