Society of France some new facts on the subject of living 

 frogs attacked by Hies (Lucilia bufonivora). M. Desquez 

 has found a third subject, at Bondy, containing some mag- 

 gots in its nose, so that it seems to leave no doubt but that 

 the species exists around Paris. M. Fernand Lataste, well 

 known for his studies on the herpetology of Gironde and the 

 environs of Paris, has noted in his excursions a probably anal- 

 ogous fact, although it may be less certain, regarding the 

 green frog (Mana viridis Linn.). An enormous subject of 

 this species, caught at the bottom of a limpid stream not far 

 from Bordeaux, had the lower jaw eaten by an ulcer, or by 

 worms. Gratiolet has published a note on the dipterous 

 larvae living at the expense of the green lizard {Lacerta vi- 

 ridissima). 



At a late meeting of the London Entomological Society, 

 Mr. Rutherford exhibited a series of laro'e brown irregular 

 masses of strong web, from 4 to 7 inches in diameter, being 

 the common envelopes of aggregations of cocoons of a species 

 of silk-worm allied to Anaphe panda (Boisduval), sent from 

 Mount Cameroons (5000 feet elevation). Each of these masses 

 contained from 130 to 150 special cocoons, and to some of 

 them were attached cases containing large larva? (still living) 

 of a parasite either dipterous or hymenopterous, probably 

 the latter. 



"The Mound-making Ants of the Alleghanies" is an inter- 

 esting pamphlet of about fifty pages, illustrated with six litho- 

 graphic plates and a number of cuts, in which Rev. Henry C. 

 McCook recounts his studies into the habits of some of our 

 ants, with especial reference to the wood- or fallow-ant [For- 

 mica rufa), whose modes of building, general style of archi- 

 tecture of the nests and o-alleries lead ins; therefrom, the re- 

 pairing of the nests, engineering, addition of stories, age of 

 hills, food, feeding-places, aphis-friends, sentinels, tree-paths, 

 water supply, recognition of fellow-ants, amity and confeder- 

 ation, night-work, winter habits, guest -beetles, guest -cater- 

 pillars, natural enemies, means of attack and defence, are dis- 

 cussed with fulness and interest, the paper being the result 

 of independent observations. 



This ant is regarded by the author as the same as Formica 

 rufa of Europe an ant whose domestic life was studied by 

 H uber, and more recently by Forel, though Mr. McCook's
