Feminz antennis quam corpus subbrevioribus _ filiformibus. 
Long., 16 1. 
At once distinguishable from its described congeners by the 
beautiful bright silvery pubescence with which its upper surface 
is patchily clothed. It is also remarkable for the coarse but not 
very deep rugulosity of the basal joint of its antenne which runs 
in transverse wrinkles. The underside of its head is like that of 
P. picipennis, Germ., except that the space between the eyes is 
divided froin the space immediately in front of it (not by a sulcus 
but) by a curved carina.

NEOSTENUS. 
NV. spinipennis, sp. nov. (Mas.) Brunneo-piceus, antennis ob- 
scurioribus, elytris (marginibus anguste piceis exceptis) 
dilutioribus; antennis quam corpus paullo_ longioribus, 
articulis 5—10 quam WV. Saundersi paullo magis fortiter 
serratis ; prothorace quam longiori vix (quam WV. Saundersi 
minus perspicue) latiori ; elytris ad apicem suturalem spina 
valida (quam tarsorum articulus 3°8 V1x breviori) armatis, ad 
latera profunde (quam WV. Sawndersi magis fortiter) excava- 
tis, costis obsoletis (quam WV. Sawndersi multo minus dis- 
tinctis). Long., 13 1.; lat., 341. 
Very like W. Sauwndersi, Pasc., but easily distinguishable by 
the characters cited above, especially by the long stout spine at 
the sutural apex of the elytra.
