Bisects Affecting the Straicberry. 53 



If this species should ever become seriously destructive (as is very unUkely), 

 its injuries could probably be checked by the use of insect poison, since the 

 time when it made the attack above described was after the fruiting of the plant. 



The Strawberry Span Worm. Nematocampa filavientaria, Guenee. 

 Order Lepidoptera, Family Phal<'vnida\ 



In June, or earlier to the southward, a wood-colored measuring-worm, 

 seven-tenths of an inch in length, with two unequal pairs of long, slender, 

 fleshy filaments, situated on the third and fifth abdominal rings, the posterior 

 pair shorter than the others, curled at the end, and finely tuberculated, may 

 be found feeding on the strawberry and currant. The head is pale rust- red, 

 with some spots of same hue on the body. Half way between the metatho- 

 racic legs and the first pair of filaments are two sub-acute tubercles, which 

 are rust-red. When the four filaments are uncurled, they are as long as 

 from the head to the tubercles. The anterior pair of filaments are pale rust- 

 red beneath at base, brown above, but tipped with white. . An oval dark spot 

 occurs behind the last pair of tubercles, and extending into the anal plate. 

 This curious woim produces a little pale ochre-colored moth, measuring 

 about an inch across the wings, with brown lines, crossing the wings, and an 

 outer border of dull brown that is continuous across both wings except the 

 apical portion of the anterior pair. They are never sufficiently numerous 

 to cause much injury. 



This, like the preceding, if it ever becomes destructive, can doubtless be 

 met with insect poison sprayed or sprinkled upon the leaves. 



The Green Strawberry Span Worm. Angerona crocataria, Guenee. 

 Order Lepidoptera, Family Phalfenidte. 



This is another of the measuring worms which has been reported injurious 

 to the strawberry; but as it has not been anywhere a serious enemy, as far 

 as I can learn, I mention it here only for the purpose of putting fruit-grow- 

 ers on their guard against it. The larva, which appears on the foliage in 

 May or June, is about an inch and a half long, gradually increasing in size 

 from the liead to the first pair of prolegs. The general color is a yellowish 

 green. There is an indistinct dorsal line, and a rather broad whitish line 

 on each side just below the spiracles, bordered above with faint purple, which 

 increases in depth of color towards the posterior rings. This becomes a pur- 

 ple stripe on the anal prolegs, and forms a mark like an inverted \. Be- 

 neath, same color as above, but with faint, interrupted longitudinal lines. 

 Spiracles white, bordered with purple. Above, on each segment, from sec- 

 ond to seventh inclusive, are five minute black dots (four in a square, and 

 one in front towards the head) and all the rings have a yellowish band on 

 the swelled part, where the succeeding segment is inserted; legs pale green. 



The pupa is .5 to .6 inch in length, and of a dark olive-green color, with 

 the exception of the abdomen, which is pale greenish yellow, and has a row
