Doryphora 10-lineata. 
A full general account, especially referring to the non-probability of 
the insect extending to Great Britain. No American beetle has as yet 
been acclimatized in Europe. The Doryphora group of Chrysomela 
occupies naturally a circumscribed area ; and the more uniform humidity 
of N.W. Europe is opposed to its establishment. The potatoes arrive 
quite clean, with no refuse to serve as a cover. The beetle is known to 
eat the tubers. H. W. Bates, J. Agric. Soc. (2) xi. pp. 361-375, pi. 
“L'Ennemi de la Pomme de Terre” (Bruxelles: 1875, 8vo, pp. 1-21, 
coloured pi.), by Oswald de Kerchove de Denterghem, contains a useful 
summary of various publications oi^ the ravages and economy of this 
insect, figuring it in its various stages, with D. juncta. Germ., for com- 
parison. 
General accounts. W. S. Dallas, Pop. Sc. Rev., April, 1875 ; A. Preud- 
homme de Borre, Bruxelles, 1875, 8vo (extr. from Bull. Soc. L. Brux.) 
translated, Ent. M. M. xii. pp. 40-42 ; Paolo Riccardi, Ann. Soc. Mod. 
(2) ix. pp. 156-198, pis, ii. & iii. [this writer, simply copying so old an 
authority as Dejean’s Catalogue, gives D. juncta. Germ,, as a var. of D. 
10-lineata ; the figures on pi. iii, amply justify the American vernacular 
name of “ Potato-bug ”] ; J. Bourgeois, Note sur la Doryphora decem- 
lineata,” Rouen, 1875, 8vo, pp. 16 (Extr. from Bull. Soc. Rouen, 1874, 
in Report to the Soci4t^ des Amis des Sciences naturelles de Rouen) ; J. 
Lichtenstein, “ La Chrysomele des Pommes de terre,” in the Messager du 
Midi, 5 April, 1875. 
The preventive agency of natural laws discussed, and European and 
American injurious beetles compared ; the Doryphora is likely to be in- 
troduced, if at all, in cotton [!], as a perfect insect : E. Candeze, OR. Ent. 
Belg. xviii. pp. xii.-xvi. Questions for consideration suggested by J. 
Putzeys, tom. cit. pp. xvii.-xix. A. Breyer, tom. cit. pp. xix.-xxi., doubts 
the possibility of the beetle being introduced among potatoes. Cf. also 
,p. xxvii. Observations on the number of annual broods; J. Leconte, 
I. c. p. xxix. A general account by H. A. Hagen, 1. c. pp. xxx. & xxxi. 
J. Putzeys, 1. c. pp. xxxii.-xxxv., refers to European beetles acclimatized 
in America, and [erroneously] deduces therefrom that the American 
beetle can bo acclimatized in Europe : a list is given of noxious insects
