During the past summer I have found this caterpillar most frequently 

 on the common Bush Juniper in Maine, but in former years have beaten 

 the cbrysalids out of the trees already mentioned. 



The caterpillar is found in July, but becomes fully grown from the 

 1st to the 15th of August. Before transforming, it spins the leaves 

 together with a few coarse silk threads and remains in the tree. Those 

 reared on the Juniper became chrysalids by the 19th or 20th of August, 

 and the moths appeared by the 9th of September, so that the pupa state 

 lasts about three weeks. The moths continue to appear until the mid- 

 dle or last of September. Those found on the Spruce appeared Septem- 

 ber 15, and a pupa found on the White Pine disclosed the moth Sep- 

 tember 13. Probably by the middle of September all the moths have 

 appeared. Whether thej- hibernate and lay their eggs in spring, or 

 whether their eggs are laid in the autumn on the terminal twigs, and the 

 species is alone represented by the eggs, remains to be ascertained. 



The moth is easily recognized by the sharp fore wings with the narrow, 

 dark, mesial band, which is black and very narrow on the inner edge, 

 and by the pale zigzag line reappearing beneath, also by the black 

 streak near the apex and a smaller apical black dot. It is closely re- 

 lated to the European T.juniperata, which feeds on the common Juniper. 



DESCRIPTIVE. 



Larva. — Body smooth, cylindrical; head smooth, slightly hilobed, not quite so wide 

 as the body. Head and body green, the color of the upper side of the juniper leaves 

 on which it feeds. A broad pale glaucous white dorsal band, on each side of which is 

 a yellowish-white line, which extends along the sides of the supra-anal plate, but rot 

 meeting its fellow at the apex. Anal legs broad and large, green, with two tuber- 

 cles which are large and rounded conical. Thoracic legs pink. Length, 16 mm . 



Pupa. — Of the usual family shape ; green, with a white lateral stripe from the head 

 to the tip of the abdomen, and another lower down along the abdomen, as well as two 

 parallel dorsal whitish stripes. Abdominal spine larger and longer than usual, flat- 

 tened vertically, acute, surface corrugated ; two stout terminal bristles excurved at 

 the ends, a much smaller pair at base of these and along the sides .of the spines two 

 additional pairs. Length, 6 mm . 



Moth. — Pale ash, base of fore wings with two bent parallel black lines, the outer 

 heavier, and marked with longitudinal stripe on the veiulets. Beyond is a broad pale 

 band slightly bent on the median vein. Still beyond is a median band margined with 

 black, narrowing more than usual on the inner margin of the wing, where the two 

 black margins meet, forming two contiguous black patches; in front the baud in- 

 closes obscure ashen ringlets. A black discal dot ; beyond, an obscure pale patch. 

 A white zigzag marginal line, the sharp scallops inclosing dark dots. Hind wings 

 uniformly pale ash color, crossed by two dusky lines. Expanse of wings, 25 nim (one 

 inch). 



THE PINE PHEOCYMA.* 



(Pheocyma lunifera Hiibn.) 



DESCRIPTIVE. 



Larva. — Body long and slender, tapering considerably behind the fourth pair of 

 abdominal legs. Head not so wide as the body, rather deeply bilobed, with a lateral 

 V-shaped white spot. A pair of small prominent tubercles on top of the eighth ab-
