LEPIDOPTEEOLOGY. 97 



chapter is given in English and German, as well as in French, and so 

 emphasises the point that a figure can be understood in any language, 

 but a description in a foreign tongue may waste much time in trans- 

 lation only to find that is not the one sought. 



Then follows a note on Liplujra braswlis, with figures of the imago 

 with its emergence scales, and of the eggs, out of which have emerged 

 parasites (Chalcids ?), which are also figured. 



A record of Sphin.r hybridisation, by Lieut G. Grosse of Pilsen, 

 occupies 15 pages ; the prominent fact here recorded is that a hybrid 

 ijaUi>hoihiae S" proved fertile with a 9 i/aUii. A specimen of the result, 

 named lidenae, is figured, and the original account by Lieut. Grosse 

 and a translation of it are given. Lieut. Grosse also reports having 

 bred three other secondary hybrids of Sphmges. These results are 

 very interesting, but fail to be fully grasped, except by those who 

 specialise in these hybrids and know the names given to them, of 

 which a number occur in Lieut. Grosse's paper ; no doubt I might, by 

 some research, learn what hybrids precisely irenae, enriliae, khidervatcri, 

 etc., may be, but 1 should understand them at once were they specified 

 as fjallii X eupJiorbiae, {;/allii x cuphurbiae) x (/allii, or as the case may be. 



There are more than 100 pp. devoted to the " Distribution and 

 Variation of C'. typhon m the United Kingdom," by H. Eovvland- 

 Brown, with a note of introduction by M. Oberthlir, calling attention 

 to the fact that the habitats of many species are being rapidly 

 destroyed, and that such studies as this should be made about each of 

 them before they disappear. He almost takes one's breath away when 

 he points out that all species, not only in Europe but everywhere, 

 should be studied with equal care, that this is only an essay on dis- 

 tribution and variation in a fraction of the area of the species, and that 

 many questions of biology, of symbiosis, of parasitism, have to be 

 similarly treated in each case. Something of the Life-history of tiphnn 

 is, hov/ever, added to the paper from Zeller, and by Mr. Frohawk ; 

 these additions, however, have no illustrations. The three plates, 

 with 86 beautiful figures of the imagines, give a very complete view 

 of the British forms of the species, notwithstanding that it is one in 

 which hardly two specimens are quite alike. 



Section VI. is a further addition to the research into the alrens 

 group of Si/ric/ithus [Hesperia), in which Prof. Reverdin is doing such 

 good work ; this is illustrated by two plates. M. Oberthlir inclines to 

 believe that S. ryfelemis is a good species. The short notice of Larche 

 is of much interest to one who has collected there. 



Section VIL introduces a study of the races of Zegris eupheme, 

 Esp. by M. S. Alpheraky, with interesting reference to various side 

 issues, and is illustrated by a plate drawn by a Russian lady artist. 

 In referring to all these plates, it is difficult to suppress adjectives of 

 approval of their excellence, but the plates are so uniformly of the 

 first quality that to do so would become too monotonous. 



Section VIII. continues, in correspondence with H3 plates, the 

 revision with figures of Guenee's species of Geometers ; it includes, 

 however, a number of other species and varieties. It deals with the 

 groups, of which prominent genera dealt with are Nyssia, Bi.ston, 

 tlemerupldla, Cleora, Boaniiia, Tvplirosia, Hypocliruiiia, (Jnophos, and 

 Psodos. 



The notice of the genus Itliysia is identical with that in the Ento- 

 7nolot/ist, 1912.
