The history of the occurrence of tho rarer Sphinges in Britain, as 

 summarized by Mr. Tutt, is also of considerable importance, as well 

 as the remarks on the structure and colours of larvae and the stridu- 

 lation bee-persecuting habits of Mandaca atropoa. The two plates 

 relate to the last-named species in its various stages, Tho volume 

 closes with an index, synopsis of contents of vols, i.-iv., and general 

 index to vols, i.-iv., the last item by the Rev. George Wheeler. 



In conclusion, we can only again emphasize our conviction of 

 the enormous value of this encyclopaedic work to all working 

 Lepidopterists. W. F. Kieby. 



The Fauna of British India, including Ceylon and Burma. Pub- 

 lished under the authority of the Secretary of State for India in 

 Council. Edited by W. T. Blanford.— i?7iv;i.c7io<rt. Vol. II. 

 {Heteroptera). By W. L. Distant, Loudon, 1904. 8vo. 

 Pp. xvii, 503 ; figs. 319. 



The second volume of Mr. Distant's important work on the Bugs of 

 India extends from Fam. 4. Lygteidae to Fam. 16. Capsidae, thus, 

 with the exception of the Anthocoridai, completing the monograph 

 of the true Land Bugs of India. The remaining Heteroptera will 

 be included, with the commencement of the Homoptera, in the third 

 volume ; and we hope that the Homoptera will be treated in the 

 same exhaustive manner as the Heteroptera. The total number of 

 Heteroptera described in Mr. Distant's first two volumes is 1471, 

 while the whole number of British species is upwards of 450. 

 Nevertheless certain families of Land Bugs are apparently more 

 richly represented in Britain than in India. Thus, Mr. Distant 

 describes only three species of Indian Saldidae, only one of which 

 belongs to the genus Salda, Fabr., whereas Mr. Saunders describes 

 17 British species, all belonging to the genus Salda. Then there 

 seem to be only two Indian species of Cimicidae, including the noto- 

 rious Cimex lectularius; whereas we have 4 species in Britain, 

 including tho insect already mentioned, which is certainly a natu- 

 ralized and not a native species with us. 



We should like to see a series of works similar to the ' Fauna of 

 British India' undertaken with respect to all the principal British 

 possessions.
