204 THE entomologist's RECORD. 



much, finds his opportunity snatched away. One may, however, 

 reasonably hope that after a time M. Oberthiir will be able to con- 

 tinue to gratify us with the results we still hope for of his prolonged 

 and ripe labours. 



The text deals with the butterflies of Algeria, and one can hardly 

 open the book anywhera without finding something of greater or less 

 interest. Perhaps the outstanding feature is the wealth of observations 

 of H. Powell on the habits and early stages of so many species. No 

 less than 237 of the 860 pp. are claimed by the genus Sati/rus, much 

 of it dealing with Powell's observations of eggs, larvae, habits, etc. 

 56 pp. contain a paper by M, Fd. le Cerf on the morphological 

 characters of the Algerian Satijri with many text figures of antennae, 

 palpi, details of proboscis, scales and scaling, legs and genital armature, 

 male and female. 



Of our British butterflies, there is a full discussion of the forms of 

 Aricia medon (L. ai/estis); Agriades thetifi {hellan/us), also receives some 

 attention as to sundry varieties. Of Colias hyale and C. cmcints (edusa), 

 synonomy is discussed. Mr. Powell reports that C. edusa lays upon 

 many and varied Lfnininiwsae, and cites lucern and other non-British 

 plants. 



Amongst the Satyri, there is a most interesting excursus on Linne 

 and the name semele. 



The portraits of Entomologists include French, Italian, Russian, 

 Swiss, American, and English Lepidopterists. 



The photographs (by Powell) of localities for various butterflies 

 are often good pictures apart from any special interest, such as pits. 2, 

 14, 46, but are always good photographs and show well the nature of 

 the country. 



The seventy-six photographs, of eggs, larvfe, &c., present some 

 excellent representations of eggs, in which the difficulty of getting so 

 large objects altogether in focus is overcome by presenting two or more 

 of each egg at different horizons, and in most instances with much 

 success, as for instance in pit. 56, eggs of Ejiinephele eudora-uiaurltanica, 

 X 25, Syi icJitkus onopordi, T^hotos. (o4: d, Q4: c, Syricldh us numida, 64/", 

 ^S. proto, 64 j, and 64 k, etc. 



When we come to the plates by M. Culot, we find illustrated chiefly 

 those Algerian species and forms that have not been illustrated in 

 previous portions of the " Etudes," just in fact as we find in the text. 

 Four forms of machaon are figured, three of var. feisthamelL Five 

 figures of Thaix rumina show curious aberrations of the denticulation 

 of the hindwings. Aporia crataegi, Antlwcharis falloiii, A. charlonia, 

 A. belia (eupheno), and Calicharis nouna occupy three plates, and 

 admirably illustrate both the species and M. Culot's art. Forms of 

 Melitaea didyma and M. deione take the next plate. Four plates of 

 Satyrus prieuri, S. ellena, S. semele, and S. nelcai follow. Melanaryia 

 mes, Kpi)tephele and Coenonympha, Lycaena iolas, (Tlancopsyche cyllarus 

 and Celastrina anjiolus occupy two plates. Plate 289 shows Scolitantides 

 (L.) abencerrayus = batnn, S. allardi and S. martini, but especially a series 

 of S. (L.) fatma, which Mr. Powell not only met with in quantity, 

 though previously barely known, but of which also he very successfully 

 followed out the life history as described in the text and illustrated in 

 the plates of photographs, and of his excellent drawings (plate 301). 

 The foodplant {Salvia argentea) is very unusual for a Lycaena. A. (L.)
