312 REPORT ON ZOOLOGY, MDCCCXLIV. 



own observations, that a large proportion, in particular the Staphyliuidte 

 and Histeridse, are attracted by the excrements of the Ants. (?) 



Schiodte (ibid. 473) has briefly noticed the Myrmecophila of Denmark. 

 Among these, Scydmcenus exilis, Er., truncatellus, Er., claviger, 111., which 

 he found exclusively in the nests of F. n<fa, and two species of Malthinus 

 call for especial mention. 



Bohemaun has attended to the Myrmecophila in Sweden (Oefvers. Kougl. 

 Vetensk. Acad. Forh. 1844, p. 155.) He collected in the nests of F. rufa 

 26 species, all of them found also in Germany and elsewhere, but of which 

 13 were additions to the Swedish Fauna. 



Manner heim has continued his examination of the nests of Ants in 

 Finland (Bull. Mosc. 1S44, p. 176) and has made no inconsiderable addition 

 to the list of Myrmecophila, among them several new species. The nests 

 yielded most in spring ; in July and August scarcely anything was found 

 besides Myrmecoxenus siMerraneus, but this in thousands. It resides, not 

 deep down, but in the uppermost galleries. It is worthy of remark, also, 

 that particular species occur gregarious in some nests, not at all in others ; 

 (such is the case with Ifyrm. subterranew, too, which the Reporter has 

 found about Berlin only in particular nests, but there by thousands.) 

 Lastly, Motschoulsky (Bull. Mosc. 812) has made some remarks on 

 Marker's paper above noticed, stating that in his former travels, as well in 

 Russia as in other countries, he had repeatedly searched the Ant-hills with- 

 out finding anything like the variety which Markel represents. The list 

 given of the species which he had observed is of no scientific value, the 

 greatest number of them being given as new, yet not characterized, or only 

 in the most superficial style. 



While the foregoing investigations concern the races which live in ami- 

 cable relations with the Ants, Cornelius has directed attention to the 

 enemies of these insects. (Eutomol. Erfahruugen, Verhand. Naturhist. 

 Vereins Preuss. Rheinlaud. Yr. 1, p. 50.) These are chiefly Carabidrc, 

 which haunt the edges of the nests, and prey upon the young brood, that is, 

 the pupae. Pterostichus cupreus, Harpalus rtijimfnis, Caralus cancellatus, 

 granulatus, Procrustes coriaceus, TapJnia vicalis, have come under his 

 observation. Gryllus campestris, also, which he found near the nests, in 

 captivity did not refuse the pupre of Ants, for which reason the author is 

 inclined to include it in the list. 



[Curtis (Royal Agric. Soc. Report, v, and also in the Gardener's Chroni- 

 cle, under the signature Ruricola) has continued his illustrations of the 

 natural history of insects which affect the produce of the field, the garden, 

 and the forest, and has figured many species of different orders, in their 

 several progressive states.] 



Desmarcst has collected the instances in which metals
