is asserted [most certainly in error] that the short- winged forms occurring 
in certain species are only nymphs ; this is succeeded by a note on the 
times of appearance, the broods in a year, &c. The history of the sub- 
ject is next considered, then the natural systematisation and “ Darwin- 
ismus,”the author asserting that the first Psocw?cc were undoubtedly evolved 
from the Emhidm. In this portion, the author has taken into consideration 
the numerous instances of aberrant neuration, which almost invariably 
point to genetic relationships ; one species is considered to exhibit a case 
of atavism. The least satisfactory features of the memoir are the ten- 
dency shown to excessive multiplication of genera (and probably also of 
species) on slight foundations, the giving of varietal names to slight aber- 
rations in neural characters, the occasional peculiar ideas as to nomen- 
clature [e.g., Psocus nehulosus is re-christened nebuloso-similisj because 
Stephens described the $ as nehulosus, and the $ as similisY], and the 
revival of obsolete names on the slightest possible foundation [e.g., P. 
longicornisy F., is identified with Phryganea saltatrixy L. ; why, the 
Recorder cannot conceive]. The descriptions are excellent, and the 
bibliographical references very full. The plates are full of well-executed 
figures, mostly of details, representing minute structural characters, 
neuration, &c., &c. The systematic portion occupies pp. 102-137 ; all 
the German species are described, and reference is made to those Euro- 
pean species not occurring in Germany. A conspectus of the tribes and 
genera appeared in the paper in S. E. Z. xli., noticed above (which was 
probably published almost simultaneously with this), but it is thought 
bettor to allude to them specially here. The author adopts 6 tribes, viz. : 
1, Psocini (including Psocus, auctt., and a new genus split ol£ from it) ; 
2, Ccecilini (including Blipsocus, which is divided into three genera, and 
Ccccilius) ; 3, Stenopsocini (which includes Stenopsocus and a new genus 
formed at its expense) ; 4, Peripsocini (limited to Peripsocus') ; and 5, 
Atropini (in which the terms Troctes and Atropos are used in the sense 
alluded to above, and an entirely new genus is erected).
