Euphanessa (Nudaria) Mendica Walk.— A. female of this species 

 deposited eggs on the sides of a box, in which it was confined, on the 2nd 

 and 3rd of July. They were of a bright red colour, and the young larvce 

 were hatched from them on the 8th of the same month. They were 

 extremely active, about one-tenth of an inch long, with cylindrical bodies, 

 and true geometers in their larval characteristics and mode of progression. 

 The following description was taken at this stage in their history : — 



Head large, bilobed, dark brown. Body above dull brownish-green, 

 with a slight pinkish tinge, and with many short black and brown hairs. 

 Under surface similar to the upper; feet and prolegs — of which latter 

 there were two pairs only — greenish and semi-transparent. 



I used my utmost endeavours to procure food for these larvae, and 

 introduced into the box in which they were confined, leaves belonging to 

 many different families of plants, but failed to find anything they would 

 eat. In the course of two or three days, they all died of starvation.

 sufficiently distinguished by its toothed antennae and longer prothorax. 

 Body linear, black, hairy with pale decumbent hairs. Flead punctured ; 

 antennae longer than the prothorax, filiform, with all the joints, except the 

 scape, pedicel, and terminal one, terminating at their internal extremity in 

 a prominent tooth, less conspicuous in the two lower ones : upper-lip, and 

 nose which is reflexed and overhangs the mouth, yellow : prothorax chan- 

 nelled, punctured, quadrangular, with the anterior angles rounded, and the 

 posterior diverging and terminating in a sharp tooth or prominence ; sides 

 rather wavy ; limb yellow : scutellum subcordate : elytra minutely and 

 thickly punctured, slightly furrowed, furrows thickly punctured ; marked 

 with a narrow yellow stripe which does not reach the apex ; there is also a 

 short yellow streak on the shoulders : base of the tibiae, claw-joint of the
