lateral stripes.. Another larva, probably belonging to the same 
species though feeding upon a different maple, presented the follow- 
ing characteristics. Head light amber, mouth parts darker ; thoracic 
shield dark amber 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 throughout 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. 
Leuccbrephcos 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 [pl. 2, fig. 1] 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
