486 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
8. Gracilia minuta Fabr. 
Qraeilia minuta Fabr. (Spec. Ins., 1781, v. 1, p. 235). 
Lagger (Psyche, Aug. -Sept. 1884, v. 4, p. 204) mentions 
breeding this species from a baud of wood {Betula lenta) 
around a gin-barrel. 
9, Bellamira scalaris (Say). 
Bellamira scalaris Say (Journ. Acad. Nat. Sci., 1827, v. 
5, p. 278-279). Packard (Hull. 7, U. S. Entom. Coram., 
1881, p. 129) writes on authority of G. Huut, "Beetle 
and pupa found uuder the bark of the yellow birch in 
July, northern New York." 
10. Leptura vagans Olivier. 
This longicorn beetle has been bred by Mr. Chitten- 
den, as he writes me, from larv;e found in the yellow 
birch. 
AFFECTING THE LEAVES. 
11. The tuknus swallow-tail. 
Papilio turnu8 Linn. 
I have frequently noticed this caterpillar on 
fig. iib.-Beiiamira scalane, the leaves of the white and poplar-leaved birch 
smiths. j ate j u September and early in October in 
Providence. The butterfly appears early in June in Xew England as 
soon as the lilac blossoms. The eggs are laid soon after the butterfly 
appears; the larva passing through five stages of growth. 
Mrs. Anna K. Dimmock gives a summary of its history (Psyche, iv, 
p. 283) as follows : 
Papilio turnus Linn. (Mantissa, 1767, v. 1, p. 536). Harris (Treatise on Ins. Injur. 
Veg., 1862, p. 268, 269) describes and figures the larva and imago of this species, which 
larva* were reared seven tachiuid Hies (allied to Morinia), which emerged from June 4 
to July 6, 1884. The digestive tract of the larva? of C. piceus is often inhabited by a 
microscopic undescribed nematode worm. 
Dendroide8 concolor Newm. (Entom. Mag., 1838, v. 5, p. 375). G. Dimmock has a 
specimen in his collection, which he reared from the bark of Betula papyracea at the 
White Mountains, New Hampshire, the beetle emerging July 8, 1^74. 
Dendroides canadensis Latreille (Consid. Gene'r., 1810, p. 212). Schaupp (Bull. 
Brooklyn Entom. Soc, July 1881, v. 4, p. 23) writes of this species, "Pupa in birch 
July 19, in beech July 23." G. Dimmock found a pupa of this species, June 30, 1874, 
under decayed bark of Betula papyracea, on Mount Washington, New Hampshire: 
the beetle emerged from this pupa July 8, 1874. 
Meravantha contracta Beauv. (Ins. Afr. et Ainer., 1805, p. 121, pi. 30, fig. 2). Halde- 
man (Proc. Amer. Assoc. Advanc. Sci., 1850, v. 2, p. 347) briefly notices the larva of 
this species. Specimens in the collection of G. Dimmock were taken at Surneld, 
Conn., by Leroy H. Sykes, in decaying bark of Betula lutea. 
Centronopus calcaratus Fabr. (Entom. Syst., Suppl., 1794, p. 52). Coquillett (Can. 
Entom., Juue, 1883, v. 15, p. 102) describes this larva very briefly. This larva is 
often very abundant in decaying birch wood. — (Mrs. Auua K. Dimmock, Psyche, iv, 
pp. 283-284). 
Mallota posticata Fabr. The larva has been found by Mr. Lintner in decaying 
birch wood. (1st Auu. Rep, State Eut. N. Y. 1882, 211-216.) 
Stenoscelix bra-is Boh. occurs in wood (Chittenden).
