Hammaticherus lasiocerus, sp. n. 
Plocederus lasiocerus, De}. Cat. 
Piceo-ferrugineus, fulvo-griseo-pubescens; capitis fronte antennisque 
griseo-villosis ; prothorace lateraliter valde tuberculato, supra 
transversim sat regulariterque plicato; elytris fulvo-testaceis, 
opacis, griseo-pubescentibus ; apicibus truncatis, utrisque bispi- 
nosis ; antennarum articulo tertio quam quarto fere duplo longiore, 
articulis tertio quartoque apice spina valde recurva armatis, 
ceteris inermibus.

‘This species somewhat closely resembles HZ. plicatus, Oliv., 
but the prothorax is more pubescent and its plication some- 
what less regular towards the middle, and the elytra are 
without dark margins. It may be distinguished from this 
and from every other species in the genus by the yellowish- 
grey villosity covering the antenne and the front of the head, 
by the long third joint of the antenne, and by the spines of 
the antenne, which are confined to the third and fourth joints, 
and which are rather short and directed very much backwards. 
Hammaticherus murinus, sp. n, 
Plocederus murinus, De}., MS. 
Parvus; fuscus, omnino denseque murino-pubescens ; protho- 
race supra leviter interrupteque plicato; elytris punctulatis sat 
dense pubescentibus, apicibus truncatis utrisque bispinosis; an- 
tennis ( ¢ ) corpore sesquilongioribus, articulis quinto ad decimum 
apice spinoso-dentatis ; antennis ( Q ) corpore vix longioribus. 
Long. 17, lat. 5 mm.

This species may be recognized by the rather close mouse- 
grey pubescence, which entirely covers it. The ruge of the 
prothorax are feebler than in other species of the genus, and 
do not seem to exceed eight or nine in number. ‘he dense 
and very fine punctuation of the elytra is scarcely visible 
under the rather close pubescence. he joints of the antennee 
from the third to the tenth are dentate at the inner apex, 
the third and fourth very feebly so, the fifth and some of the 
following almost spinose. 
Hammaticherus luridipennis (Chevr., MS.), sp. n.
