lateral stripes. Another larva, probably belonging to the same 

 species though feeding upon a different maple, presented the follow- 

 ing characteristics. Head light ambsr, mouth parts darker ; thoracic 

 shield dark aniber with the lateral and posterior margins a dark 

 green. Body a dark olivaceous green with conspicuous, whitish, 

 round, subdorsal tubercles, these latter being large enough so as to 

 suggest, in certain lights, a light, subdorsal stripe; lateral ridge 

 and ventral surface yellowish transparent, tubercles thereon equally 

 as prominent as those in the subdorsal region but less conspicuous, 

 as they are unicolorous. True legs sooty transparent, black at 

 the articulations, prolegs concolorous with the ventral surface. 

 This larva is sparsely clothed with very long, slender, whitish hairs. 

 Described from a single living specimen, which may prove to be 

 a younger stage of the form characterized above. 



Birch leaf Bucculatrix (Bucculatrix canadensisella 

 Chamb.). This insect was extremely abundant in New York State 

 during the fall of 1901, at which time a very considerable proportion 

 of the birch foliage was thoroughly skeletonized. Its work in that 

 year was observed througdiout the western two thirds of Massa- 

 chusetts as well as in the eastern and northern parts of New York 

 State. 



This species was present September 18, 1907, in large numbers 

 at Arlington, Staten Island, where a considerable proportion of the 

 birches had the leaves seriously affected. The insect appeared to 

 be numerous over an extensive tract, many of the trees being well 

 dotted with the characteristic, circular, white, pseudo cocoons of 

 the larvae. None had constructed the peculiar ribbed, white co- 

 coons in which the species hibernates. 



Leucobrephos brephoides Walker. The year of 1907 was made 

 notable by Dr Theodore P. Bailey of Albany taking in April, two 

 specimens of this rare species in St Lawrence county. Dr Bailey 

 was fishing and his attention was attracted to these rapid flying 

 moths hovering over some stones near a stream. The insect, kindly 

 determined by Dr H. G. Dyar of the United States National 

 Museum, is extremely rare in collections, not being represented by 

 specimens' in either the National Museum or the New York State 

 collections prior to this season. The moth [pi. 2, fig. i] has a wing 

 spread of almost one inch, is dark brown, the forewings being 

 marked with a broad, angulate, yellowish white subterminal line, 

 while the hind wings bear an irregular, large, angulate, yellowish 

 white blotch near the middle. The antennae of the male are pecti- 

 nate while the body is thickly clothed with long, dark brown hairs. 

 Dr James Fletcher of Canada records taking this species April 16
