Sir John Lubbock, president of the Biitish Kni miologieal society, cal led attention the otlier day in his animal address to the researches of M. Fabre on the liabits of insects. Amongother tliings M. Fa'ore has continned his eurious observationa on the solitary wasps. He describes the singular state of paralysia into wbich thyy throw their victims, wblcli, if killed, would decay, and if buried allve would, in loeit struggl es, al most infullibly destrov 'ie egg or young larvn of the va. . The wasp, however, stings them in Micha nmnner as to pteroe the gatigl;n and (hns without Killing them, almost deprives them of all power of inovement. One soecies of sp, ex which preys on a laige grasshopper (Ephipp'gera), ar. er luw' g alniost paralyzéd lier viotim in the usual manner, throws it on i La back, bends the hcad so as to extend the art'colators of the neck, and then, se:''.in'; tbe membrane botween (he head and body with her jaws, cri'shes ie fe:;nglion - truly a marvelous instinct. M. Fabre found that even a'.ar this treatment the victims retuin sume power of digestión, and be was able considerably to prolong their livs by feeding them with syrup. l'nlike the genus Sphex, Uembex liriiigs froiii time Ui time fresh lood lo her young, and it. is remarkable how the Bembex rememben (if one mayuse such ;t word) the entrance to lier cel], eovered as it is with Band, exactly tp ordinary eyes like that all round. Yet she liever makes a mistake or loses ter way. )n the other hand, M. Fabre found that if lic removed the surface of the earth and the passage, thus bxpostngthe eell and the larva, tlie Bembex was quite at a loss, and did not even reccgnize her own olTspring. It sreins as ie' she knew the doors, nurneryand tlie iassage, but not her child. nother ingenious experiment of M. Fabre's was made with Chalicodotna. 'l'his genus is enclosed in au earthern cell. ihrough wblch at maturily the yoang insect eats its way. M. Fabre ïound uit if he pasted a piece of paper round the cell the insect had no dilliculty in ealroq through it, but if he inclosed the cell in a pa[)ercase, so that there was a sjiaee even of only a few lines between tlie cell and the paper, in that c;vse the paper fonned an eiïectual prison. Tiie instinct of the insect tauglit it to bite tbrough one enclosure, but it bad not wit enough to do so a second time.
