370 THE CANADIAN ENTOMOLOGIST. 



Stage II. — Length 3.5 mm. General colour, some blackish-brown 

 with a light stripe on dorsum, others light brownish with a creamy stripe 

 on dorsum. Head .5 to .6 mm. wide, sparsely covered with short light 

 hairs and long slender dark hairs, bilobed, black at apex and on cheeks ; 

 frontal triangle whitish, with a slight tinge of brown. In the darker speci- 

 mens almost the whole of the head is black. Dorsal tubercles large, with 

 exception of the two anterior tubercles on segments 5 to 12, inclusive, 

 which appear smaller, and are like minute dots. The large dorsal tubercles 

 are now situated in a distinct light brown band. Lateral, stigmatal and 

 ventral tubercles smaller than dorsal series, varying in size from lateral 

 down. Between lateral and stigmatal series of tubercles are brownish 

 blotches, which give the appearance of stripes, or bands. These markings 

 are not so plain on the darker specimens. The bristles from dorsal 

 tubercles are black, with the exception of the small tubercles on segments 

 5 to 12, inclusive, which bear one or two whitish hairs. Remaining 

 tubercles bear blackish and whitish bristles. Stigmata brown. Thoracic 

 feet and prolegs concolorous, darkened at tips. 



On the 27th June most of the larvae passed the second moult. 



Stage III — Length 5 mm. General appearance blackish hairy 

 larvae, with a pale yellowish strij^e on dorsum, which is almost imper- 

 ceptible in some specimens. In the majority of the specimens, however, 

 this stripe was plainly distinguishable. Head. 8 to i.o mm. wide, bilobed, 

 shiny, blownish black, sparsely covered with long blackish hairs ; frontal 

 triangle lighter in colour, with dark centre, in some specimens all black. 

 Dorsal tubercles large and shiny black, and bearing black bristles, varying 

 in length, some long and some short. Medio-dorsal tubercles on segments 

 5 to 12, inclusive, are very small, and bear two or more short white hairs. 

 This series of tubercles almost touches the pale yellowish dorsal stripe. 

 Lateral, stigmatal and remaining tubercles smaller than dorsal tubercles, 

 and bearing black and white bristles. In some specimens the skin of the 

 body is a deep black, with the exception of the dorsal stripe ; others are 

 lighter in colour of skin, and have the appearance of two stripes on the 

 sides, but this is due to the black shiny tubercles being more plainly 

 noticeable than the skin. Stigmata dark brown. Thoracic feet con- 

 colorous, splashed with shiny black ; prolegs concolorous. 



On the ist July a number of larvae passed the third moult, and by the 

 ■;rd all had moulted.
