larva do not return in the spring of the second year to feed on the dead 

 wood at the entrance of their burrows, but bore on directly up or down 

 the centre of the limb, attaining a distance of from sixteen to twenty-four 

 inches before pupating, in which case the beetle escapes by a round hole. 



S. coHcv/or, Vol. XX., 8. — Some of the larvae of this species, Hke in S. 

 Fayi, bore in the centre of the limb some distance, the beetle escaping by 

 a round hole, which, I think, is cut by itself, as one from which a beetle 

 was crawling appeared to have been newly made. 



Dicer ca prolongata, Vol. XX., 65. — The statement that this species 

 breeds in conifers, while probably correct, requires more confirmation. It 

 has, however, been ascertained that it breeds in some species of the Sali- 

 cacece. Mr. Blanchard records its occurrence in Massachusetts, in June, 

 on the trunks of young poplars and on poplar logs (Populus tremiiloides). 

 Mr. F. Bowditch took it on the same tree in the Rocky Mountains, and 

 also on a species of willow (Salix) ; while in the mountains of Colorado, 

 Mr. T. D. A. Cockerell took the beetle and probably its larvae from this 

 same poplar, when splitting it for firewood (Ent. Month. Mag., XXIV., 

 232). 



Myrmophilous Coleoptera, Vol. XX., 161. — The following species must 

 be added to the list : — 



Biotiis formicarius (Casey, Bull. Cal. Acad. Sci., 11. , 8). — Occurred 

 at Los Angeles, California. " This interesting species lives in the nests 

 of a small, pale brown ant." — Casey. BioUcs is a new genus in Cten- 

 ISTIDES. A figure of the insect accompanies the description. 



Pteiiidium evancscens Marsh. — This species, according to Matthews, 

 is common in America, Europe, the Canary Islands and Madeira. F. W. 

 Maeklin in his Coleopt. Myrmecophila Fennica (No. 102), states that 

 it is often taken, both mature and immature, in the nests of Formica rufa, 

 as well as in other situations. 



Limiilodes paradoxus Matth. — This curious insect is described and 

 figured in Ann. Lye. Nat. Hist., N. Y., VIIL, 409. It was first taken by 

 Dr. Brendell in Florida, and subsequently by Mr. Ulke in New York and 

 the District of Columbia, frequently in the nests of a yellow ant, which 

 Dr. Leconte thought identical with the species with which Ceophilus 

 monilis lives. My specimens are from Massachusetts. — Blanchard. Pro- 

 bably not rare. Trichopterygia (Matthews), 157. 



Trichopteryx fascicular is Hbst. — Inhabits Europe and North Ameri-
