Skinner and Mr. Fox for examining Cresson’s type of WV. 
depressa, and reporting the characters given above. All these 
insects have simple mandibles; Mr. Viereck kindly examined 
Cresson’s type of depressa in respect to its mandibles some 
years ago. 
N. depressicauda agrees with the description of hoodiana 
(Proc. Phila. Acad., 1903, p. 608) in practically every char- 
acter except those given in the table. The third submarginal 
cell, however, is less narrowed above. 
N. skinnert is quite a dark insect, with the middle of face 
and front (not involving the clypeus) black ; flagellum strongly 
dusky, but clear red at extreme apex ; third antennal joint a 
little shorter than fourth ; second abdominal segment with a 
large yellow mark on each side, third with yellow dots ; apical 
and basal margins of the segments infuscated ; pygidial plate 
broad, but not so broad at apex as that of WV. depressiuscula ; 
basal nervure going a moderate distance basad of t. m. 
The type has the upper half of the second transverso-cubital 
wanting on both side. 
Numerical Distribution of Some Insects.

The following notes were compiled during the summer of 
1905, excepting in a very few instances as stated. In record- 
ing them, I walked a mile and a quarter from home to a small 
pond and back again over the same route. Thus day after 
day I confined myself almost exclusively to this ground. It 
consisted of about one-quarter mile of macadamized rvads, 
five-eighths of untilled fields and one-eighth of plowed land 
in corn, one-quarter in woods and the usual surroundings of 
a small pond on the edge of a copse. 
I think the scarcity of some species in my list is alone ac- 
countable by the fact of their comparative or almost total se- 
clusion in nature. The Coleoptera are represented so well on 
account of the fact that they are my favorite order, and con- 
sequently were pursued more closely and continuously. Even 
here, however, there are many instances where their ways or
