486 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



8. Gracilia minuta Fabr. 



Gracilia viinuta Fabr. (Spec. Iqs., 1781, v. 1, p. 235). 

 Lugger (Psyche, Aug. -Sept. 1884, v. 4, p. 204) mentious 

 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 (Bull. 7, U. S. Entom. Comm., 

 1881, p. 129) writes on authority of G. Hunt, "Beetle 

 and pupa found under the bark of the yellow birch in 

 July, northern New York." 



10. Leptura vagans Olivier. 



This lougicorn beetle has been bred by Mr. Chitten- 

 den, as he writes me, from larvte found in the yellow 

 birch. 



AFFECTING THE LEAVES. 



11. The turnus swallow-tail. 



Papillo turnus Linn. 



I have frequeutly noticed this caterpillar oil 



Fig. 175.— Bellamira scalaris. the leavcs of the white aud poplar-lcavcd birch 



Smith dej. jj^^^j ljj September aiid early in October in 



Providence. The butterfly appears early in June in New England as 



soon as the lilac blossoms. The eggs are laid soon after the butterfly 



appears 5 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 



larvae were reared seven tachinid flies (allied to Morinia), which emerged from June 4 

 to July 6, 1884. The digestive tract of the larvae of C. piceus is often inhabited by a 

 microscopic uudescribed nematode worm. 



Dendroides 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, 1874. 



Dendroides canadensis Latreille (Consld. Gen^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. 



Mei-acantha contracta Beauv. (Ins. Afr. et Amer., 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 Suffield, 

 Conn., by Leroy H. Sykes, in decaying bark of Betula lutea. 



Centronopus calcaratus fahr. (Entom. Syst., Suppl., 1794, p. 52). Coquillett (Can. 

 Entom., June, 1883, v. 15, p. 102) describes this larva very briefly. This larva is 

 often very abundant in decaying birch wood.— (Mrs. Anna K. Dimniock, Psvche, iv, 

 pp. 283-284). 



Mallota posticata Fabr. The larva has been found by Mr. Lintner in decaying 

 birch wood. (Ist Ann. Rep, State Eut. N. Y. 1882, 211-216.) 



Stenoscelis brevis Boh. occurs in wood (Chittenden).
