646 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Larva. — Body of the usual form, tapering cowards the head and tail. Head not so 

 wide as the prothoracic segment, pale whitish green. Body pale whitish green ; two 

 dusky subdorsal longitudinal lines, with faint lateral dusky lines beginning on the 

 side of the prothoracic segment. Spiracles large, conspicuous and dark. Each seg. 

 ment with one large transverse dorsal wrinkle a little behind the middle. Ten ab- 

 dominal legs. Length, 20""". 



9. Tineid larva. 



The sycamore trees in and about Providence have for several years 

 been much infested by this caterpillar, one or two of which are to be 

 found in nearly every leaf. It makes one or two large folds in the leaf, 

 living within a web in the crease. At the end of September (the 25th) 

 it forms an irregular oval cocoon among the leaves preparatory to 

 pupating. The cocoon is broad and flat, formed of reddish silk. 



Larva. — Of the usual cylindrical shape, tapering a little towards each end. Head 

 not so wide as the first segment behind, somewhat pointed ; amber-colored, with 

 two distinct black spots on each side. Body pale straw yellow, with sparse pale 

 hairs, one-third as long as the body is thick. Thoracic feet dark, abdominal ones 

 concolorous "with the body. Length, 10""". 



A larger larva. — Straw-yellow, with two subdorsal dark-brown lines, and behind 

 the head a supraapiracularlineextendingasfar as the third pair of spiracles. Spira- 

 cles black. Length, 20™">. 



10. The sycamore blotch-miner. 



This miner forms on the upper side of the leaf in October a broad 

 mine doubled on itself and meeting so as to form a long, irregular round 

 blotch one-half inch in diameter. 



The following species also occur on the sycamore : 



Order Lepidoptera. 



11. Eacles imperialis Hiibner. Raised by Abbot in Georgia. (Manu- 



script plate in library Bost. Soc. Nat. Hist.) Illinois (Walsh). 



12. Halesidota caryw (Horr.). Beutenmiiller. 



13. Nepticula maximella Chamb. 



14. Nepticula clemensella Chamb. The larva of these two species and 



iV. platea live in the upper surfaces of the leaves. (Can. Ent., v, 

 p. 125. Chambers.) 



15. Cirrha platanella Chamb. The larva feeds on the under side of 



the leaves, and pupates in a tube composed of silk and the down 

 from the leaves. (Chambers.) 



Order Coleoptera.
