Robust, pyriform. Uniform dull red*, rather thickly clothed with short, 

 prostrate yellowish pubescence. Beak short, roughly and coarsely punc- 

 tate in front of antenna; head carinate between the eyes. Thorax short, 

 about as wide as long, feebly narrowed in front; disc coarsely and densely 

 punctate and with a narrow median impressed line which extends for- 

 ward on the occiput. Elytra very roughly sculptured with rows of coarse 

 punctures; intervals narrow, marked with finer punctures. Length 4.5 

 5.5 mm. 



Lake, Starke, Mai-shall and Yigo counties, Indiana, scarce: 

 June 15 30. Occurs on hazelnut, alder and rose-mallow. Not 

 rare near New York City, on hazel, Corijlttx <iiii<Tic<tii<i Walt.. 

 rolling leaves. May July. Ranges from New England and Nova 

 Scotia west and southwest to Nebraska and Arizona. According 

 to Packard ( 1S!)0, <J:!2'|, the singular, thimble-like rolls of this 

 weevil may be found in June and July on the alder. When about 

 to lay her eggs, the female begins to eat a slit near the base of 

 the leaf on each side of the midrib, and at right angles to it. so 

 that the leaf may be folded together. Before beginning to roll 

 up the leaf she gnaws the stem nearly off, so that after the roll 

 is made, and has dried for perhaps a day, it is easily detached by 

 the wind and falls to the ground. When folding the leaf, she 

 tightly rolls it up, neatly tucking in the ends, until a compact, 

 cylindrical solid mass of vegetation is formed. Before the leaf 

 is entirely rolled she deposits a single egg, rarely two, in the 

 middle next to the midrib, where it lies loosely in a little cavity. 

 These rolls remain on the bushes sometimes for several days, but 

 probably drop by the time the larva escapes from the egg, and it 

 seems probable that the grub uses the roll for a shelter until it 

 matures and is ready to enter on its transformation to a beetle." 



Subfamily IV. PTEROCOLIN/E. 



THE SiroKT-wixoioi) WKKVILS. 



The single species representing this subfamily in the eastern 

 United States differs from those of the two preceding subfam- 

 ilies not only in having the thorax acutely margined and ex- 

 cavated beneath as in some Histerids, but also in having a 

 shorter and more rounded form, in the antenna- 1 being inserted 

 much nearer the eyes, and in having the elytra shorter, sepa- 

 rately rounded and widely separated at tips, thus exposing not

 tarsi; and a melanic form occurs at Mt. Washington, X. H., in August. (Frost.)
