THE CANADIAN ENTOMOLOGIST, 



descend the peaks ; therefore there cannot have been communication 

 between these branches since the retreating ice stranded the two southern 

 colonies. Yet they are not distinguishable from one another. Examples 

 from Labrador, even also from Ungava Bay, lat. 59°, are precisely like 

 examples from the White Mountains and Colorado, and in fact these three 

 branches of the species are not known to differ by a scale or a hair.

The following is a list of the entomological works of Dr. C. Zim- 

 merrnann : — 



1. Monographic der Carabiden, Erstes Stueck, Berlin and Halle, 

 1831, 8vo., pp. 8 and 76, contains the family Zabroides, five genera, with 

 twenty-six species ; review in Oken Isis, 1832, vol v., p. 539, vol. x, p. 

 1 1 17; extracted in Silbermann Revue, 1833, T. I., p. 45-47. The author's 

 copy belongs to the library of the museum. 



2. Monographia Amaroidum.— The work was interrupted by the 

 author's voyage to America. The library of the museum possesses out 

 of Zimmermann's own library a few sheets, printed in Europe in 183 1, in 

 two parts (proof sheets). The work is written in Latin. First part, p. 

 1-48 (three sheets), the general description of the family x'Ymaroides: — 

 I. de capitis partibus, p. 5 (os, instrumenta masticandi) ; II. de trunci 

 structura, p. 16 (coUum, pectus, pedes, alae) ; III. de abdomenis segmentis, 

 p. 31 (dorsum, venter, appendices) ; general division of the Adephaga 

 and Carabidae, p. 36, in 12 stirpes; de corporis partibus externis, p. 40, 

 the plate (table 1) is not present, probably never printed, then follows 

 the general description, p. 44, which gives the characteres sexuales (not 

 finished), p. 48. 



The second part (also not finished), Monographia Amaroidum, quotes 

 the first part as: — Dispositio methodica nova Coleopterofum. Adepha-
