PSYCHE. 



[April— June 1SS5. 



of this species, 30 June 1S74. under deoavcd 

 bark of Brtiila papyracea, on Mt. Washing- 

 ton, N. II.; the beetle emerged from this 

 pupa S July 1S74. 



J\lerac(nif/i(i contracfa Beauv. (Ins. Afr. et 

 Amer., 1S05, p. 121, pi. 30, fig. 2). Ilalde- 

 man (Proc. Amer. assoc. advanc. sci., 1S50, 

 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 Betiila 

 lutea. 



Boli/ol/icriis bifKrcus ¥ahr. (Entom. syst., 

 Suppl., 1794, p. 40). The larvae, pupae and 

 imagos of this species are found in Polrporiis 

 betuliniis, which grows on dead bircli trees. 

 Larva, pupa, and a male imago arc figured 

 b^' Packard (Guide study ins., 1S69, p. 474). 

 Kirby, as quoted by Bethune (Can. entom., 

 Nov. 1S73, V. 5, p. 21 1), says that this species 

 is found in a boletus of the birch. Some 

 habits of this beetle are mentioned by Har- 

 rington (Can. entom., Dec. 1882, v. 12, p. 

 260-261). Candeze (Mdm. soc. sci. Liege, 

 1S61, V. 16, p. 365-36S, pi. 3, fig. 9) gives a 

 detailed description of the larva, with figure; 

 and Hay ward (Bull. Bost. zool. soc, July 

 18S2, v. I, p. 35-36) briefly describes the larva 

 and pu]'>a. 



Hoploccphala bicoriiis Fabr. (Gen. ins. 

 mant., 1777, p. 215). This insect feeds upon 

 different kinds of fungi, some of them para- 

 sitic on decaying wood of Befiila. Kirby's 

 description of the imago is quoted by Bethune 

 (Can. entom., Nov. 1873, v. 5, p. 210-211). 

 Harrington (/. c, Dec. iSSo, v. 12, p. 261) 

 mentions its fungivorous habits. 



Diapei is hydiii Vahr. (.Syst. eleuth., iSoi, 

 V. 2, p. 5S5). This species, both as larva and 

 imago, feeds upon I'olyponis betuliuns, a 

 fungus that grows on dead trees of Bctula 

 alba, and the beetles, according to G: Dim- 

 mock, are often very abundant about the first 

 of July. Harrington (Can. entom., Dec. 1S80, 

 v. 12, p. 261) briefly describes the imago. 



Centroiiopiis ca Irani/ 11 s Fabr. (Entom. 

 syst., Suppl., 1794, y. 52). Coquillctt (Can. 

 entom., June 1883, v. 15. p. 102) describes 



this larva very briefly. Tliis larva is often 

 very abundant in decaying birch wood. 



N^yctobates pciisyh'anica He Geer (M^m., 

 177.V V. 5. p. 52; pi. 13, fig. 10). Schaupp 

 (Bull. Brooklyn entom. soc, July iSSi, v. 4, 

 p. 23) writes of this species, "Pupae in beech 

 July 15; in hemlock July x8; in birch July 



21."' 



J'/iellopfis obcoidala Kirby (Fauna bor.- 

 aiTier., 1S37, P'- 4' P- 236). The larva of this 

 species has been found by G: Dimmock, on 

 Mt. Washington, N. H., in Polyporiis bcttili- 

 ««.«, the large white fungus common on dead 

 trees of Betiila alba. The imago frequents 

 the same fungus during June, July, and Au- 

 gust. 



Telep/ionis biliiica/iis Say (Journ. Acad, 

 nat. sci. Phil., 1S23, v. 3, p. 1S2). Packard 

 (ist ann. rept. inj. and benefic ins. Mass., 

 1S71. p. 26-2S, pi. 1, fig. 7-8) describes and 

 figures larva and imago and writes that the 

 pupa of this species "early in May becomes 

 a beetle, when it eats the newly expanded 

 leaves of the birch." Riley (4th ann. rept. 

 state entom. Mo., 1S72, p. 29-30) describes and 

 figures the larva and imago, stating that the 

 larva has been found to eat larvae of Carpo- 

 capsa pomonclla. 



Campylus denlicoruis Kirby (Fauna bor.- 

 amer,, 1S37, pt, 4, p. 145). G : Dimmock has 

 reared this species from larvae found in partly 

 decayed bark of Beliila papyracea, on Mt. 

 Washington, N. H. The imagos emerge 

 from the pupae about i July, and are abun- 

 dant during July in the White Mts. 



Mclaiiotns ? pannnpiinctatiif Melsh. (Proc. 

 Acad. nat. sci. Phil., Nov. 1S44. v, 2, p. 151- 

 152). A Mclanotus, probably this species, 

 was taken in the same cavity with its pnpal 

 skin, in decaying wood of Biliilu alba, at 

 Milton, Mass.. 17 Oct. 1SS4. 



Mclaiioliis ? commiiins Gylleiihal (Schonh., 

 Syn. ins., v. i, pt. 3; App. 1S17, p. 13S-139.) 

 A MeUiHotttS, probably this species, was 

 taken in decaying wood of Bcliila alba, at 

 Milton, Mass., 17 Oct. 1SS4.
