the corresponding tufts of the second segment. On the rerpain- 

 ing segments, excepting the last two, the four upper tufts are of 

 a clearer shade of white. The remaining tufts are dirty black- 

 ish. On the eleventh segment the double warts become each 

 two separate ones, placed longitudinally. Legs black. Head 

 black, with a V-shaped lighter mark. A few lighter blotches 

 above, at the bases of the double warts. Length 40 mm. One, 

 found October 5, spun October 9 a loose cocoon of white silk 

 and changed in two days. The moth appears early in May and 

 in August. It is a rare species in this locality. Larva eats 

 Rubus and Betula. 



Calocampa nupera Lint. Large and stout. Brilliant apple- 

 green, lighter between the segments. A double lateral narrow 

 stripe, black above and greenish white beneath. This stripe 

 passes through the breathing orifices, which are orange colored 

 and catch the eye at once. An inconspicuous whitish dot just 

 above the breathing orifices, and above this three white dots 

 (the middle one just above the other two) from which project 

 several minute hairs. Head and legs green. Feet red. Length 

 60 mm. In its early stages it is light green, closely resembling 

 the young larva of (7. eurvlmacula, and having the appearance 

 and habits of a Geometrid, its full number of legs being devel- 

 oped during its successive moults. I reared a small brood of 

 these larvjB this spring from the egg, but had no leisure to ob- 

 serve their successive changes. When mature they presented 

 many striking variations, some being almost black, with the 

 three white spots above the breathing holes strongly contrast- 

 ing ; others were of a rich shining brown, some pale brownish 

 green ; but the majority were of the form described above. 

 The larva enters tiie ground towards the end of June, and 

 changes to a pupa about the middle of August. The moth 

 appears in September and October. 



Calocampa ciirvimacula Morr. Color dirty greenish brown, 

 appearing in certain lights as if frosted; immaculate beneath ; 

 mottled with darker shades of brown above. A narrow dorsal 

 dirty white line edged with brown. Faint oblique blotches on 

 the sides, composed of mottling a little darker than the ground 

 color of the larva. Head shinino; brown with darker mottlino;.
