428 On new Species of Histeride. 
CHLAMYDOPSIS, Westwood, Trans. Ent. Soc. Lond. 
p. 317 (1869). 
I propose to retain as the type of this genus C. striatella, 
Westw., because the author of the genus characterizes this 
species more fully than C. Dubowlati, and both species cannot 
now be assigned to the same genus. In C. striatella the legs 
are elongate and constricted at their bases from a point close 
to that where the tarsal groove ends, and in this respect differ 
from those of Orectoscelis, which are similar to an Hretmotus. 
In C. striatella also there is a broad prosternal keel, which is 
marginate and widened out before the coxe towards the 
lateral thoracic edges, and the mesosternum is bisinuous in 
outline anteriorly. C. inquilina is a typical Chlamydopsis, 
but should have been described as “ pronoto haud trans- 
verso,” for its thorax is nearly square and evenly reflexed 
on three sides. In the genus Orectoscelis there is no 
prosternal keel, and C. Duboulaii certainly (from Westwood’s 
figure) and C. sternalis, Blk., probably belong to it. Excel- 
lent outlines of the sterna are given in the ‘Thesaurus Ent. 
Oxon.,’ 1874, of Westwood’s two species, and serve to show 
the differences in the sternal structure in the two genera. 
Saprinus pygidialis, sp. n. 
Ovalis, parum convexus, niger, nitidus ; fronte concava, punctata, 
stria obsoleta; pronoto circum punctato, stria integra; elytris 
striis dorsalibus 1° basi abbreviata, 2° dimidiata, 3* brevissima, 
4* et suturali basi conjunctis, humerali externa integra; prosterno 
acute carinato, striis in foveam ascendentibus; tibiis 5-6-den- 
ticulatis. 
L. 33 mill. 
Oval, somewhat convex, black and shining; the head 
concave behind the epistoma, with the surface evenly, not 
densely, punctured ; the thorax, marginal stria complete, 
with the anterior and lateral borders broadly punctate, disk 
widely and finely punctulate; the elytra, striz, outer humeral 
complete and bent apically, inner wanting, oblique basal very 
fine, first dorsal well shortened apically, second dimidiate and 
third one third of the elytral length, fourth same length as 
the third and joined to the sutural, which is almost com- 
plete; the propygidium and pygidium are clearly and 
somewhat densely punctured, before the apex there is a deep 
transverse sulcus shaped like a widened-out V with sinuous 
edges, behind the suleus the apex is almost smooth ; the 
prosternum is transversely smooth at the base and the striz
