genera not yet studied. New species of Harpalus, Amana, Bembidium, Tachys, 
etc., add only new names to our list and nothing to our knowledge. A remark— 
able feature is the separation of Harpalus veridiceneus into five distinct species. 
As the pamphlet is a fugitive publication and not accessible to the mass of Co— 
leopterists we reproduce the table separating the species. Of course the table 
applies only to those metallic green specimens that run as viridiceneus in col- 
lections. _

Smaller species. Head smaller; elytra as wide as prothorax,.... “enescens. 
Weare not quite certain that this separation without a study of allied 
species or of all the species of the genus 1s advisable. We have hitherto refrain- 
ed from attempting to separate the large number of specimens we have as viridie- 
neus, fearing that on the same basis we may discover even more species. How- 
ever, very little is know of Harpalus, and Lt. Casey may be entirely warranted 
in his conclusions.

Not strictly Entomological, but interesting to all students of nature are 
some recent issues of the “‘“Humboldt Library” the aim of which is to bring 
standard scientific literature within the reach of those whose length, or a more 
correctly shortness of purse, does not enable them to purchase the ordinary 
editions. Of the works recently issued are to be recommended Bates, Natura- 
list on the River Amazon; and Darwin, Origin of Species. 
The publishers deserve hearty support in their very laudable effort thus to 
bring such literature within the reach of all.

Transactions No. 5, of the Ottawa Field Naturalists Club, is at hand, and is 
a pleasant surprise. The matter contained in itis quite as valuable as that 
contained in many volumes with more pretentious titles. Of interest for Ento- 
mologists is a list of Ottowa Coleoptera. Local lists are always of value, aa 
especially to the systematist in generalizations of geographical distribution. 
This list is compiled by Mr. W. H. Harrington and shows that gentleman to be 
a careful collector, and aclose observer. We regret that other orders are only 
very generally touched upon. Why will students rush into Coleoptera and Lepi- 
doptera when such wide unworked fields exist. in other orders, Diptera and 
Hemiptera especially.
