Length i}i inch, nearly cyhndrical. Head small, black and shining, 

 with a few short blackish hairs. Body above black, with a yellow mottled 

 with orange dorsal stripe, and two similar but very much broken ones 

 along each side. Between the dorsal and subdorsal stripes there is a very 

 broken line of a bluish white colour. Each segment has from ten to 

 twelve small black warts from each of which radiate a few black and grey 

 bristles. Beneath bluish slate grey. 



On June 19th, it was observed that these larvae had changed their 

 appearance as follows : The dorsal stripe is deep yellow and is composed 

 of two oblong spots placed longitudinally on the middle of each segment, 

 and several lighter yellow ones placed transversely on the folds between 

 the segments. The upper lateral stripe is narrower and more broken, 

 being composed of marks of irregular shapes and sizes. The lower stripe 

 is broken up mto a few scattered streaks, and the broken line of bluish 

 white spots has disappeared. 



Beneath, pale drab with a tinge of yellow and a few minute black 

 dots. Prolegs same colour as the under surface, but with a shining black 

 patch on the outside of each. Feet dark brown with light markings. 



 Entered pupa stage June 19th, 20th; emerged July 12th to 14th; 

 duration of pupa stage, 23 to 24 days. 



One female laid a large batch of eggs July 14th ; examined under the 

 microscope were found to be smooth, round, flattened at base, honey yel- 

 low j diameter .028 of an inch. 

 '- Eggs hatched July 25th ; duration of egg stage 11 days. 



Young larvae, length .10 of an inch. Head brown, shining, with a
