30 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 
May 1894, in Bavaria, when examining an old felled silver fir, I 
found hundreds of the larvee of P. piceae, and among them many 
larvee of a species of /thagiwm, a longicorn beetle ; and it is just 
possible that in such a case the latter larvee may be useful by 
destroying the Pissodes galleries. 
(c) The beds of the pup, with their coverings of sawdust and 
chips. The pupa of /Hylobius abzetis also lies in such a bed, but 
only in stumps or roots. 
(d) Typical host-plants— 
P. notatus on Pinus (various species). 
P. pint on Pinus, seldom on spruce (Picea eacelsa). 
P. piniphilus on Pinus. 
P. piceae on silver fir (Abies pectinata). 
P. harcyniae on spruce (Picea eacelsa). 
P. scabricollis on spruce (Picea excelsa). 
P. validirostris in pine cones. 
Pissodes notatus, the Small Brown or White Spotted 
Weevil. 
Description.—This red-brown beetle measures, excluding the 
proboscis, from less than } inch to a shade over 4 inch. The 
posterior angles of the wrinkled prothorax project sharply, and 
its hinder edges show two sinuous excavations. Both the upper 
and under surfaces of the beetle are powdered with white scales. 
On the upper surface of the prothorax stand four well-marked 
white points and a fifth on the scutellum. The elytra have two 
transverse bands of scales, one in front and one behind their 
middle. The front one, which is non-continuous at the suture,! 
is yellowish on either side externally, whitish internally. The 
hinder band has almost the same coloration, It is broader 
externally than internally, and is continuous right across the 
wing-covers. 
The larva is a fleshy somewhat wrinkled, curled, legless 
grub, with a brown scaly head and strong gnawing jaws. The 
only difference between larve of the Pissodes species is one of 
size. Away from their food-plants, they practically cannot be 
differentiated.

the elytra.
