curring in Xylcboriis dispar, near which this beetle may be placed ; the cha- 
racters of the S indicated by EichhofF. Bostrichus delphinii (Rosenh.) 
belongs to Thamnurgus (Eichh.). 
Xylcborus alni (Muls. & Rey). Perris (Ann. Soc. Ent. Fr. 4e s6r. tome vi« 
pp. 195-19G) indicates the characters of this species, united by Schaum and 
De Marseul with Bostrichus saxeseni (Ratz.), but which is more nearly allied 
to B. monographus (Fab.). — Bostrichus alni (Georg) described in the same 
year as Mulsant’s species, belongs to Dryocoetes. 
Crotch (Entomologist, iii. p. 133) remarks on the synonymy of some species 
of this family. 
Xyloterus quercus (Eichh.) and Toniicus quadridens (Hart.) are recorded as 
British by Sharp ; also T, lichtensteinii (Ratz.) by Crotch. See Rye, Ent. 
Ann. 1867, p. 93. 
Kylurgus pilosus (Ratz.). On the characters of British examples of this 
species, see Rye, Ent. M. Mag. ii. p. 258. 
Cryphalus asperatus (Gyll.). E. Heeger (Sitzungsber. Wien. Akad. liii. 
Abth. i. pp. 533-537) describes the natural history and metamorphoses of this 
species, = ? granulatus (Ratz.). He also illustrates the details of structure 
of the perfect beetle on the first of his four plates, and the characters of the 
larva and pupa, the burrows of the former, and the wing of the beetle on the 
second. 
Polygraphus puhescens. Heeger also (1. c. pp. 538-542, pi. 3, 4) describes 
the natural history and metamorphoses of this species.
