April — June 1SS5.' 



PSYCHE. 



285 



specimens of this beetle were taken, 17 Oct. 

 1S84, at Milton, Mass., in decaying wood of 

 Bcttilu alba, under circumstances that left no 

 doubt that t i- bred in the wood. 



Ela/er nigricollis Ilerbst (Natursvst. . . . 

 ins.; KKfer, 1S06, v. 10, p. 73, pi. 164, fig. 7). 

 Coquillett (Can. entom.. June 18S3, v. 15. p. 

 loi) briefly describes the larva, which he 

 obtained from decayed wood of J^iiciciis. 

 Reared fVom decayed wood of Betitla alba, 

 the Ijeetle emerging 3 May 1SS3 from wood 

 collected the preceding April, in Cambridge, 

 Mass. 



Clirysobothrissexsignata Say (Trans. Anier 

 phil. soc, 1S39, ^'- 6, p. 15S). Packard (Bull. 

 7, U. S. entom. comm., iSSi, p. 12S) writes 

 of this species, "Beetle and pupa found in 

 the yellow birch June i, Providence." 



Ccruchus picciis. Weber (Observ. entom., 

 iSoi, p. S4). The pupae are mentioned by 

 Fuchs (Bull. Brooklyn entom. soc., Dec. 

 iS.;2. y. V p. ^9' -^^ being very common in 

 an old beech stump, and are briefl}' described. 

 The larvae are mentioned byG:Dimmock 

 (Direct, collect, coleopt. , 1S72, p, 20) as liv- 

 ing '• in decayed chestnut and willow." The 

 larvae are very abundant in decayed and fal- 

 len wood of Bf/iila alba during autumn. 

 Qiiite a large number of larvae taken in Mil- 

 ton, Mass., 10 Nov. 1SS3, fed through the 

 winter and produced a single beetle. From 

 these larvae were reared, seven tachinid flies 

 (allied to Moriiiia), which emerged from 4 

 lune to 6 July 1SS4. The digestive tract of 

 the larva of C. /icctis is often inhabited by a 

 microscopic nndescribed nematod worm. 



Afacroilac/yliif siibspivosiis Fabr. (Syst. en- 

 tom., 1775. p. 39V This beetle devours the 

 leaves of Betiila alba. Its metamorphoses 

 were described by Harris (Mass. agric. repos. 

 and journ.. 1S27. v. 10. p. I-12'), and many sub- 

 sequent descriptions and figures have been 

 given, among which may be mentioned Fitch 

 (ist and 2nd rept. ins. N. Y., 1S56, p. 245- 

 252), Packard (Guide study ins., 1S69, p. 

 4S4), Riley (5th ann. rept. state entom. Mo., 

 1873. p. 108-110), Tliomas (6th rept. state 



entom. 111.. 1S77, p. 103') and Lintner (ist 

 ann. I'ept. state entom. X. Y., 1SS2, p. 227- 



Dtchelotiytlia clongatula Schdnh. (Synon. 

 insectorum, 1S17. t. i, theil 3, p. 210). Pack- 

 ard (Guide study ins., iS6y. p. 454) says this 

 species *' is found in Jime on the leaves of 

 the birch." 



Tl/Yii:aliis fiilgliliis Erichson (Gerniar 

 zeits., 1S44, bd. 5, p. 458). G: Dimmock 

 (Direct, collect, coleopt., 1872, p. ig-20) 

 writes " Tlie larvae feed upon a fungus {Poly- 

 porit:^ bi-liil/ftns) which is parasitic upon the 

 trunks of white bircli trees." This beetle is 

 common in New England, and its larva 

 agrees very closely with the description and 

 figure of the larva of T. limbatia. from Eu- 

 rope, as gi\en b\' Chapuis and Candeze 

 (Mem. Soc. sci. Liege, 1855, v. S, p. 417-419, 

 pi. 2. fig. 6). A large number of larvae, 

 taken in Belmont, Mass., produced beetles 

 after a short period of pupation, on or about 

 27 June 1S7S. 



Trogosita corthalis Melsh. (Proc. Acad, 

 nat. sci. Phil., Oct. 1S44, ^'- -> P- '°9)- 

 Schaupp (Bull. Brooklyn entom. soc, July 

 iSSi, v. 4, p. 23) writes of this species, "Lar- 

 vae in birch July 8, in beech Aug. 14, in sugar 

 maple Jidy 19." 



Ifs saiigiiiiioh'iitiis OVw. (Entom., 17S0, v. 

 2, no. 12, p. 8; 1>1. 2. fig. 14). G- Dimmock 

 (Can. entom., April 1871. v. 3, p. 15) notes 

 that he found this species '• about fresh-cut 

 maple and birch stumps where the sap was 

 flowing." 



IJ>s fasciatiis Oliv. (Entom., 17S0, v. 2. no. 

 12, p. 7-8; pi. 2, fig. 13). G: Dimmock (Can. 

 entom., April 1S71, v. 3, p. 15) mentions that 

 this species is found about fresh-cut stumps 

 of Betiila where the sap is flowing. 



Hymenoptera. 



Ticvicx coliimba Linn. (Syst. nat., 1758, 

 ed. 10, p. 929). Harris (Rept. ins. injur, 

 veg., 1841, p. 389-391) describes the egg. 

 larva, and imago of this insect, giving wood
