72 THE CANADIAN ENTOMOLOGIST. 



gorum. The characters of the family (p. i) are followed by the systema 

 of the family in twelve genera (p. 1 1 ). 



1. Leirus Megerle, p. 1 2, twelve species, four new. 



2. Lioscelis, Zimm., p. 31, nine species, two new (not yet finished). 

 The third sheet is by error marked the fourth, and the pagination, p. 

 49-60, is wrong, instead of p. 33-48. 



I have given purposely a detailed account of the two papers, only 

 known by proof sheets, out of Zimmermann's library, as they contain, 

 indeed, the most elaborate account of the general characters of the family. 

 The description of the genera and of the species, as far as contained in 

 the papers, is very detailed. 



The paper on Amara is quoted in my Bibliotheca II., p. 304, No. 2, 

 It is in some way different from the Latin paper just described. It is 

 published in German and translated in French, also the papers Nos. 3, 4 

 and 5. Besides those papers, after his death Dr. J. L. LeConte has pub- 

 lished the two well known in the Tr. Ent. Soc. , Phila., 1868, on Scoly- 

 tidse, and in 1869, synonymical notes on Coleoptera. Dr. J. L. LeConte's 

 Scolytidae, p. 149, says : — " Among the MSS. of my deceased friend, 

 Zimmermann, I find several partially completed memoirs, which contain 

 not only systematic ideas of much value, but descriptions of many new 

 species belonging to our fauna." Nevertheless he has published nothing 

 more of them, and I am informed by Dr. J. H. Horn that nothing more 

 of Zimmermann's papers was found after Dr. J. L. LeConte's death. 



The following report is given in a letter from Zimmermann to Th. W. 

 Harris, July 4, 1853 (in the library of Boston N. His. Soc), it must not 

 be forgotten that the letter was written before Chapnis and Candeze 

 appeared : — 



What I have observed about the beetles, grubs and their use for a 

 methodical synopsis I will subscribe here with a few words only, for the 

 thermometer rises again about 100°.
