graph in preparation, and remarks on certain genera. The deficiency of 
legs in Campsurus and allies is probably due to their being shed with 
the pupa-skin j in some all the legs appear to be cast by the $ , in others 
the anterior pair is retained. The separation takes place between the 
femur and trochanter. Indications of new forms are given.

Selys-Longchamps, E. de. Synopsis des Agrionines, 5“© Legion, 
Agrion (suite), pp. 1-282. Bruxelles : 1877, 8vo. (Published also 
in Bull. Ac. Belg. (2) xli. pp. 247-322, 496-539, 1233-1309, xlii. 
pp. 490-531, 952-991 ; but as the separate form of this Synopsis is 
always referred to, the pagination therein given is retained.) 
The last part of this Synopsis appeared in 1865, comprising the genus 
Argia in its broad sense ; the present includes all the remaining Agrio- 
nina, excepting the genera Telebasis, Argiocneniis, and Hemiphlebia. An 
analysis of the arrangement is also given in CR. Ent. Belg. xix. pp. 
xxxv.-xxxvii., xlviii.-l. Agrion (in its broad sense) is divided into two 
great divisions, and as almost all the sub-generic terms used are new, the 
tables are here reproduced. 
I. — A spine or acute point at the apex of the 8th segment of the ^ , 
beneath. 
Section 1. — The 10th segment of the $ somewhat elevated. 
A. Inferior sector of the triangle originating before the 
basal post-costal nervule. 
A. With pale post- ocular spots. Females di- 
morphic. 
a. Arculus placed beyond the second ante- 
cubital nervule. Pterostigma similar 
in all the wings Ceratura 
(subg. n.), p. 7. 
b. Arculus normal. Pterostigma of the 
anterior wings of the $ differing from 
that of the posterior. 
aa. Pterostigma of the $ not touch- 
ing the costa in the anterior 
wings ..... Anomalagrion, 
bb. Pterostigma of the $ normal . Ischnura. 
IJ. No pale post-ocular spots. Pterostigma similar 
in the four wings . . . . . . Am])hiagrion 
(subg. n.), p. 40.
