28 THE CANADIAN ENTOMOLOGIST, 



Stage V. — Head dull yellowish, translucent ; width 1.9 mm. Body 

 green, marked with opaque yellow ; twelve short, transverse, intersegmen- 

 tal, dorsal bands, reaching below the level of wart ii., that between joints 

 13-14 broken into three dots. Many irregular dots, about nine on each 

 side above the straight, narrow superstigmatal line, and nine below it, 

 none on the tubercles, which are concolorous or brownish (iii, to v. are 

 brown) ; four black tubercles on anterior edge of cervical shield. A 

 yellow line on the divergent anal feet. Tubercle iv. at the lower edge of 

 spiracle. 



Stage VI. — Head retracted at apex under joint 2 ; dull yellowish \ 

 width 2.5 mm. Body thick and flat, joints 11 to 13 tapering, anal feet 

 outstretched backward, all the feet with long claspers, slender, normal. 

 Yellow-green, clear, but not translucent, the light yellow marks as before, 

 but the dorsal transverse bands shorter (just below tubercle ii.), except 

 the broken one between joints 13 and 14, which almost touches the 

 stigmatal line; dots more numerous (about 12 to 18 instead of nine in 

 each space), some irregular. No black dots on cervical shield. These 

 have suddenly disappeared ; spiracles brown, just below the narrow 

 superstigmatal line ; cervical shield and anal plate with a yellow edge. 

 Setffi pale, long subventrally ; tubercles obsolete, not coloured, iv. oppo- 

 site lower edge of spiracle. Feet pale whitish, dorsal vessel dark. 

 Length 23 mm. The larva sits flatly on the back of the leaf. 



At the end of this stage the larvae spun cocoons of white silk between 

 partly bitten up leaves. Imago in about three weeks. 



Found on gum tree (Liquidambar) at Glendale, L. I.; also at Morris 

 Plains, N. J. 



A PROLONGED SEASON OF OCCURRENCE FOR 

 SCHISTOCERCA AMERICANA. 



At VVooster, Ohio, this species was observed in the fields on May 

 26, and at Alliance, nearly due east, on October 24, while at Bridgeport, 

 in the extreme eastern central part of the State, it was found, active, on 

 November 4, all during 1898. It appears to have been more numerous 

 of late in the vicinity of the south shore of Lake Erie than elsewhere in 

 the northern portion of the State, and more abundant than I have former- 

 ly observed it in the same latitude in Indiana and Illinois.
