BY W. SAUNDERS, LONDON, ONT. 



Three specimens of this larva were taken Sept. 16th, feeding on Oak. 



Length, 1.30 in. ; cylindrical. 



Head large, slightly bilobed, black with a faint white streak down the 

 front, as far as the middle, where it becomes forked, a branch going to- 

 wards each of the palpi. Mandibles black, palpi white at base, tipped 

 with black. 



Body above black, thickly covered with tufts of bright yellow and 

 black hairs. On the second, third and fourth segments, the hairs are 

 mixed, yellow and black ; those of the second and third segments over- 

 hanging the head. From the fourth to the eleventh segments inclusive, is 

 a dorsal row of black tufts, the largest of which are on the tenth and 

 eleventh ; the fourth and eleventh segments have also a black tuft on each 

 side, near the base. The hairs on the sides of the body, from the fifth to 

 the tenth segments inclusive, are all bright yellow, while those on the sides 

 of the twelfth and thirteenth, are mixed with black. On the third, fourth, 

 eleventh and twelfth segments, are a few long, spreading, yellow hairs, 

 much longer than those on the other portions of the body. 



The under surface, is a little paler in colour, especially between the 

 prolegs ; feet black and shining, with faint lines of a paler hue ; prolegs 

 pale yellow, faintly tipped with reddish brown. 



In a few days after their capture, these larvae entered the chrysalis 

 state, within a yellowish grey oval cocoon, constructed of silk, interwoven 

 with the hairs of the larva ; the perfect insect appeared on the 4th of June 

 following.
