ENTOMOLOGY. 311 



Onthophafftts rubricottis, Hope, Euchlora horsfieldii, Hope, Popillia cyanea, 

 Ncwm., JUHUIOS roylii, Hope, Corypkocera nigricornis, Gory, Lucanus lunifer, 

 Hope, and chevrolatii, Chenu, are species already known as peculiar to the 

 Himalaya mountains. To the tropical forms belong of Orthoptera, Acridinm 

 ruficorne and peregrimm, 01. ; of Hemiptera, Scutellera nobilis, Belostoma 

 annulatum, Cicada, pulchella, TVestw., Polyneura ducalis, Westw., wliile the 

 aquatic species oiRanatra, Nepa, Notonecta, Corixa, Hydrometra, wear quite 

 the livery of the European. The Hymenoptera are signalized by Teuthredi- 

 uidre of the genera Cimbex, Hylotoma, Tenthredo, and a Bombtis like the 

 European, while Sphex argentata, Polistes macaensis, Eumenes conica, Vespa 

 cincta, F., and Xylocopa latipes are forms characteristic of Southern Asia. 

 Among the Dipteraj^pa^ scurra, Eristalis campestris, tenax, sa/iHippobosca 

 equina are identical with European species, and others are closely allied, 

 only single species of each of the genera Penthetria, Pangonia, and Asilus, 

 belonging to the tropical forms. The Lepidoptera and Coleoptera are 

 treated of more in detail, and most of them figured in twenty-eight plates. 



Of D'Orbigny's Voyage dans 1'Amerique meridionale, 

 some progress lias been made with the entomological por- 

 tion, so that the families Cleridse, Melyridse, and Telepho- 

 ridse may now come under review. The issue of the plates 

 is far in advance of the text. 



The history of the insects indigenous to the nests of 

 Ants has already reached a considerable extent, through 



the attention paid to it in various quarters. 



Markel (Germ. Zeitschr. v, 193) has given a summary of all that had 

 been published up to the date, comprehending every species observed in 

 company with Ants, but distinguishing such as are not attached to them 

 exclusively. The number of species extends to 284, only 100 of which are 

 distinctively the associates of Ants. Formica rufa KfAftdiginosa, have the 

 greatest train; along with the former 100, with the latter so many as 150 

 have been reckoned. F.fusca has much fewer ; again they are numerous 

 with F. cunicularia. F. ni(jra,Jlai:a, Myrmica cespitum, rubru, afford little; 

 and none have yet been found in the nests of the rest. Among the Coleop- 

 tera the largest proportion belong to the family Stapkyl'midce (159 species of 

 41 genera) ; next to these the Histerida and Pselaphidce ; the remaining 

 families present only individual species, or such whose occurrence in that 

 situation may be considered merely casual. Among Hemiptera, Uiptera, 

 and Hymeuoptera, no inconsiderable number of species frequent the nests of 

 Ants, but of them only a few detached species have been discriminated. A 

 number of Arachuida, Myriapoda, and Thysanura, too, live in the nests of 

 /'. rufa. The solution of the question, what part these races act in the 

 colonies of Ants is yet distant. The author is disposed to infer from his
