Book Notices. 



Dr. Carlos Berg of Buenos Aires, has sent us a series of his papers, 

 mostly from the "Anales de la Sociedad Cientifica Argentina'"', and giving 

 notes and descriptions on and of a large number of Coleoptera, Ltpidopltra 

 and Hemiptera. It is interesting to note, that in addition to our old and 

 well known friends Agrotis ypsilon, and saucia, A. incivis, and Cindaphia 

 bicoloralis also occur in the Argentine Republic. For A.ypsilon we have 

 as synonyms frivola Wallgr. and robasta Blanch. A. saucia has as syno- 

 nym angulifera Wallgr., and the Doctor thinks that Spaelotis stictica 

 Blanch., S. punctulaia Blanch., Agrotis impaclaWlk., and Noctua aethiops 

 Phil., will also prove forms of this protean species. A. incivis is A . ante- 

 posila Gn. , and A. leniicidosa Moritz. Cindaphia bicoloralis Dr. Berg 

 himself had re-described as Botis amiculatalu and here corrects himself. 

 It proves that the synonym mill is grinding there as well as here. 



On the Parasites of the Hessian Fly. By C. V. Riley, Ph.D., Proc. U. S. 

 Nat. Mus. VIII, 413—422, PI. XXIII, Sept. 1885. 



An interesting contribution to the history of this well known pest, 

 describing and illustrating: — Merisus destructor (Say), M. (Homoporus) 

 subapterus n. sp., Eupelmus allynii (French), Tetrastichus productus n. sp. 

 and Platygaster Herrickii Pack An extract characterizing the species 

 was read before the recent meeting of the A.A.A.S. , and the life history 

 of the species is carefully traced. 



Fourteenth Report of the State Entomologist on the Noxious and Bene- 

 fical Insects of the State of Illinois. By S. A. Forbes (3d Kept.), for the year 

 1884. pp. 136, pi. XII. Also an Appendix containing "General Indexes to the 

 first Twelve Reports of the State Entomologists of Illinois. ' ' 



Contains an Entomological Calender, and articles on Corn Insects; 

 Wheat Insects; Grape Insects; Black- and Raspberry Insects; Agrotis C. 

 nigrum; Apple and Pear Insects; Maple and Elm Insects; and Miscellan- 

 eous Notes. 



The Index to the 12 Reports is a valuable contribution, modelled 

 upon Prof. Riley's Index to the Mo. Reports. The title page enumer- 

 ates Francis LeBaron as one of the State Entomologists — we were under 

 the impression that William LeBaron held that office. 



Quite a large number of new species of several orders are described 

 more or less completely, and a new Tenlhredid genus (Melallus) is very 

 incompletely characterized. 



The article on Wheat Insects is interesting because it covers to an 

 extent the ground covered in the publication by Prof. Riley (previously 

 noticed) on the parasites of the Hessian fly.
