THE PINE SESIAN. 727 
the body being ornamented with small scales instead of spots of tine 
pubescence. It is a beautiful black insect, with a broad white lateral 
vitta on the prothorax, and a very irregular one on the elytra, with 
many scattered small spots, densely clothed with depressed, very small, 
round, chalky white scales. Punctures of elytra very large, distant ; in- 
terspaces smooth, shining, except where covered with scales. Length, 
14.4 mm (.57 inch). 
59. Crijpturgus atomus Le Conte. 
(Larva, Plate xxiv, Fig. 4, 5, ba, 5b; Pupa, Fig. 5c.) 
Canada, Massachusetts, and New York; under bark of 
dead pine branches. Length, l mm (.04 inch). 
This species, though common in white pine bark, is 
especially destructive to the spruce, and is more fully x 
described under the head of spruce insects. It occurred 
in abundance at Brunswick, Me., in all stages of develop- 
ment, from the fully-grown larvae to the beetle, under 
the bark of white pine stumps (the trees having been 
felled the previous November), from the middle of July lurgus'~atomZ'. 
until the 1st of September, and probably still later. smith del. 
60. Ernobius tenuicornis Le Conte. 
Order Coleoptera ; family Ptinidje. 
According to Le Conte this beetle has been detected in the boughs 
of Pinus rigida in Massachusetts by Mr. Blanchard. (Trans. Amer. 
Ent. Soc, viii, p. xxiii, 1880.) 
61. The pitch-eating weevil. 
Pachylobius picivorus (Germar). 
A black weevil very similar to Rylobius pales, but destitute of any spots or dots> 
and having the same habits. This occurs in the southern part of our State, and 
becomes common farther south, but I have never met with it to the north of Albany. 
(Fitch.) 
Le Conte separates as a distinct genus from Hylobius, H. jpicivorus, 
which differs greatly from the other allied species of Hylobius by the 
tibiae being much shorter and stouter and expanding at the tip. It is 
abundant under pine bark, adds Le Conte, in the Southern States, less 
frequent in the Middle States. 
62. The pine sesian. 
Harmonia pini Kellicott. 
Order Lepidoptera ; family ^Egeriad^e. 
Boring in autumn under the bark and into the superficial layers of wood, usually 
just below a branch, a white smooth caterpillar an inch long, transforming to chrys- 
alids late in May, the moth appearing from the middle to the end of June. (Kellicott.) 
Mr. Kellicott gives the following account of this insect: 
When studying the larval habits of Pinipestis zimmermani in 1873-79, I met with 
the larva and pupa skins of two moths evidently different from the pine pest, yet
