Survej^ of Canada' (1875-76), and are stated to be better pre- 

 served than any that have been obtained from other American 

 localities. The species are Formica arcana, Pimijla senecta and 

 decessa, Calyptites antediluvianum (Braconidse), several midges 

 (Chironomidse), very imperfect, Boletina sepidta (Mycetophilidse), 

 Brachijpeza (two specimens), and Trichonta Dawsoni (ditto), 

 Dolichopidce (several fragments), and several species of Muscidae 

 of different genera; Prometopia depilis (Nitidulidse), Lachnus 

 petrorum (Aphidae), and portions of one of the Libellulidte. 



A note on certain insect remains, chiefly Libellideous and 

 Blattideous, from Cape Breton, by Mr. S. H. Sciidder, is published 

 in the 'Proceedings of the Boston Society of Natural History' 

 (vol. xviii.). 



Descriptions, with figui'es, of two fossil caterpillars of SatyridcB 

 are published by M. Daudet, in Rev. & Mag. ZooL, 1876, pi. 11. 



An insect which appears to belong to the interesting family 

 Stylopidce has been found in amber, and described by Menge in 

 the ' Schriften' of the Nat. Hist. Soc. of Dantzig, and is noticed 

 in the Ent. Mo. Mag., June, 1877. 



Evolution, Parthenogenesis, Mimicry. 



A paper, by Mr. Packard, opposing Mayer's views upon the 

 Ontogeny and Philogeny of Insects, appears in the ' Monthly 

 Microscopical Journal' for February, 1877. 



A notice of Dr. Weismann's remarkable memoir on the genetic 

 character of the markings of the larvae of Sphingidce appeared in 

 •Nature,' March 22, 1877. 



The ' Proceedings of the Academy of Natural Sciences of 

 Philadelphia' contain a recent paper, by Thomas G. Gentry, on 

 the genetic Philogeny of Lepidoptera, illustrated by an arboreal 

 diagram, in which these insects are assumed to have been derived 

 from the aquatic Trichoptera through Paraponyx, with Arctica 

 as the progenitor of the order. 



Mr. S. H. Scudder has published an article upon the " Classifi- 

 cation of butterflies, with special reference to the position of the 

 Equites, or Swallow-tails," in the ' Transactions of the American 

 Entomological Society' (vol. vi.). Adopting the principles of 

 Evolution, the author assumes that the Nocturnal Lepidoptera 

 ai'e the progenitors of the Diurna, which he divides into four 

 families only, Nymphales, Rurales (Erycinidre and Lycsenidfe),
