154 . The Ottawa Naturalist. [Feb. 



tion was taken: Length when mature 34 mm., cylindrical 

 in shape, tapering towards the head, which is slightly smaller 

 than segment 2. The whole of the body is pale green, 

 the dorsal vessel a darker green. The dorsum is covered with 

 short, whitish, crooked lines, which slope from about 

 1 mm. above the stigmatal band to a faint, whitish crooked 

 line which borders the thin median skin through which 

 the dorsal vessel is seen. Stigmatal band yellowish- 

 white; spiracles whitish, ringed with black. All the feet 

 concolorous with body. Head slightly paler than 

 body, no markings; ocelli black; tips of mandibles 

 blackened. The larvae spun cocoons and pupated soon 

 after collection, and the moths emerged on June 9 and 10. 



A very brief description of this larva was published 

 by Thaxter in 1876.*

A single larva of this species was found on mint at 

 the Central Experimental Farm, on May 9, 1901, from 

 which the following description was drawn : Length 3 1 mm. 

 Head 2 mm. wide, rounded, slightly indented at vertex, 

 lobes full; concolorous with body excepting antennae, 

 which are paler and slightly brownish at tips; mouth 

 parts also slightly brownish ; ocelli black; hairs on face 

 slender. Body cylindrical, plump , tapering towards extremi- 

 ties, light green on dorsum, dark green on sides and venter, 

 the whole body spotted with white dots. From centre 

 of dorsum to spiracles are five stripes, all white with excep- 

 tion of spiracvilar stripe, which is yellow. Spiracles faintly 

 orange, ringed with black. Tubercles normal, white, setae 

 dark, tubercle IV in a line posterior to lower end of spiracle. 

 Thoracic feet and prolegs concolorous with venter. On 

 May 13 the larva began to spin its cocoon, and by the 

 16th had changed to pupa. The moth emerged on June 4. 

 In 1899 a cocoon was fotmd on a celery leaf, the moth 

 emerging on Aug. 10.

 (Y); 9, 14 Julv, 1900, (Y) ; 20 Julv, 1904, (G); "9 Aug., 

 1900, (G). 



Mr. Young has found the larva on cabbage, from 

 which he reared the moth on 13 Sept., 1906. Fletcher, 

 in 1878, found the larva at Billings' Bridge feeding on Red
