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, 

 14^4mm (_57 inch). 



59. Cryptiirgus atomiis Le Conte. 

 (Larva, Plate xxiv. Fig. 4, 5, 5a, ob ; Pupa, Fig. 5c.) 



Canada, Massachusetts, and New York; under bark of 

 dead pine branches. Length, l"""" (.04 inch). 



This species, though common in white pine bark, is 

 especially destructive to the spruce, and is more fully ^ 

 described under the head of spruce insects. It occurred 

 in abundance at Brunswick, Me., in all stages of develop- 

 ment, from the fully-grown larvre to the beetle, under 

 the bark of white pine stumps (the trees having been 

 felled the previous November), from the middle of July ^lurgus'~'cuomi!'s. 

 until the 1st of September, and probably still later. Smith dei. 



60. Ernohius tenuicornis Le Conte. 

 Order Coleoptera ; family Ptinid^. 



• 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. 



Pachylohius picivorus (Germar). 



A black weevil very similar to Ri/IoMhs 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. picivorus^ 

 which differs greatly from the other allied species of Hylobius by the 

 tibite 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 ^GERiADiE. 



Boring in autumn under the bark and into the superficial layers of wood, usually 

 just below a branch, a white smooth caterpillar au inch long, transforming to chrys- 

 alidslate 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 1878-'79, I met with 

 the larva and pupa skins of two moths evidently different from the pine pest, yet
