Locality, Running about on the leaves of undergrowth, in the forest 
on Cape Mesurado, Liberia. 
Under sufficient magnification the bristles of the head and segments 
appear as round hollow structures with about four longitudinal rows of 
very fine appressed teeth directed distad. The bristles of the terminal 
fascicle are more slender and have for a part of their length large ap- 
pressed spines in opposite pairs something as shown by Latzel for Poly- 
xenus lagurus. Nothing was seen similar to the apices of the hairs as 
figured by the same author. 
This new genus is to be distinguished from Polyxenus and Lopho- 
proctus’ by the form of the antennæ and the distribution of the dorsal 
sete. In Polyxenus the antennz are short ; in Lophoproctus they are 
long, but the apical joint is subequal to the penultimate. 
Polyxenus has two transverse dorsal rows of rather remote short 
clavate and strongly serrate setæ, while Lophoproctus has a single row. 
The type of the latter genus is eyeless, although Mr. Pocock proposes 
to iuclnde a species with eyes, Polyxenus lucidus Chalande. 
From the West Indes Mr. Pocock has described another Polyxenus’ 
which, to judge from the drawing, has four tufts of sete on each seg- 
ment, and also a scattering row along the posterior margin. The an- 
tenn are said to be very long, but appear not to be clavate, and the 
relative proportions of the joints are not stated. It is probably the 
type of a new genus having affinities with the African rather than 
with the Europear forms. 
By the discovery of Saroxenus the distribution of the Pselaphog- 
natha is considerably extended. Should members of the group be 
found in other tropical regions there will be added assurance of the 
antiquity of the subclass, and of the probability ~ relationship with 
such fossils as Paleoocampa.—O. F. Coox.

North American Crambidz.—Dr. C. H. Fernald publishes as 
a bulletin from the Massachusetts Agricultural College an important 
Monograph of the Crambidæ of North America. The author has long 
been recognized as tne leading authority on the micro-lepidoptera. 
The new genera Eugrotea and Pseudoschcenobius are characterized as 
well as several new species. The bulletin is admirably illustrated by 
three plates in black and white and six plates in colors, beautifully 
printed. This will certainly prove one of the most satisfactory ento- 
mological publications ever issued from the Agricultural Colleges.
