THE CANADIAN ENTOMOLOGIST 135 



becoming about one-half wider to the tip, punctuation close, rather fine but 

 deep and more or less confluent, extending well back on to the interocular area, 

 median impressed line deep at middle, becoming evanescent between the eyes 

 and just before the rostral apex. X'ertex very finely and sparsely punctate. 

 Above each eye is a band of pearK- scales. Scrobes anteriorly visible from above, 

 broad, becoming wider and shallower posteriorly, the deeper median i^ortion 

 directed against the lower l)order of the eye. AntenUcX rather stout, scape 

 reaching about to the middle of the eye, funicle a little longer, second joint about 

 one-half longer than the first, third to sixth subequal, each about as long as 

 wide, seventh a little longer and heavier, club oval, pointed, slightly annulate, 

 pubescent except at base. Prothorax barely longer than wide, moderately 

 convex longitudinally as well as transversely, apex truncate, about three-fifths 

 as wide as the base, which is feebly bisinuate, sides divergent but nearly straight 

 to the point of greatest width a little in front of the middle, thence subparallel 

 but slightly concave to the base. Disk closely clothed with pearly scales through 

 which protrude moderate sized mostly scattered granules, each with a median 

 puncture. Middle line distinctly but not strongly canaliculate. Scutellum 

 minute, transverse, scaly. Elytra conjointly slightly arcuat^ly emarginate at 

 base, wider just behind the obliquely rounded humeri, thence nearly parallel 

 sided to behind the middle, whence they are arcuately narrowed to the apex. 

 Disk convex, strongly declivous behind, densely covered with pearly scales 

 and with rows of granules like those on the prothorax. Beneath roughly and, 

 in general, closely and rugosely punctured, a patch of scales on each side of the 

 metasternum and of the second abdominal segment. Middle and hind legs 

 with an incomplete femoral annulus beyond the middle, more pronounced on 

 the hind pair. Tarsi hairy above, first three joints golden pubescent beneath, 

 third joint broad, bilobed. Claws simple, approximate at base and only slightly 

 divergent. Length, excluding rostrum 9.50 mm., of rostrum about 1.75 mm. 

 Width across elytra 4.20 mm. 



Compared with P. gemmalns Lee, this species is similar in a general way, 

 but that insect has the beak carinate instead of grooved, the antennae more 

 slender, the legs uniformly scaly and the elytral granules smaller as well as 

 differently arranged. \n P. siilcirostris the elytral vestiture is mostly condensed 

 into an irregular curved band extending from the humerus to a point near the 

 suture a- little behind the middle, and a large, irregular patch before and extend- 

 ing to the apex. 



The specimens communicated to the National Collection of insects at 

 Ottawa, and to myself, were all sent by Mr. Hanham, who, however, informs 

 me that he did not capture them himself. They were found at Quamichan 

 Lake, nearby, and were handed to him by his neighbor, Mrs. Ethel A. Leather, 

 who found them first early in May, 1916, feeding upon the leaves of Liliuni 

 pardalinum, in the broad light of warm and sunny days. She found many 

 hundreds of the beetles, most of which were destroyed, and, on digging about 

 the roots of the lilies, quantities of the larvae and a few pupa.'. There is every 

 likelihood that the species may reappear as a pest of some importance along the 

 north Pacific coast.
