THE CANADIAN ENTOMOLOGIST. 



Head medium sized, rather flat in front, slightly bilobed, and of a pale 

 green colour, with a few very fine hairs, invisible without a magnifying 

 lens, scattered over its surface ; mandibles tipped with black. 



Body above bluish-green, with thickly set longitudinal stripes of whitish 

 and yellowish. A double whitish dorsal line, with bordering lines of 

 yellowish-white, neither of which are unbroken, but are formed of a suc- 

 cession of short lines and dots. Below these, on each side, are two or 

 three imperfect white lines, made up of short streaks, and much fainter 

 than those bordering the dorsal line ; spaces between the segments yel- 

 lowish. The skin all over the body is much wrinkled and folded. 



The under surface is green, with a tinge of yellowish between the 

 segments ; feet yellowish-green, prolegs green, faintly tipped with brown. 



The moth is of a pure white colour, with three or four reddish-brown 

 spots on the costal margin of each of the fore-wings, and with a faint 

 curved line of the same, crossing them a little beyond the middle ; it 

 expands i inch, This species was kindly determined for me by Dr. A. S. 

 Packard, of Salem, Mass. 



Metrocampa perlata Gucnec. — This pretty white geometer, which is 

 larger than the last species referred to, I have bred from a larva which was 

 found feeding on willow, and which entered the chrysalis state before I 

 had an opportunity of describing it. 



ACRONVCTA OBL'INITA S?)l. 



6° Abbot. — This insect, which 

 is admirably represented in all 

 its stages in fig. 39, is well 

 described by Mr. C. V. Riley, 

 in his " Third Annual Report 

 on the Noxious Insects of Il- 

 linois." In addition to the 

 food plants there given, I have 

 found the larva quite common 

 on the cultivated Strawberry, 

 and also on the Wild Rasp- 

 berry. My specimens were 

 taken early in September, and 

 produced the imago about the 

 fig. 39- middle of the following June. 



The larva is very handsome, while the moth is of a very plain grey colour.
