TRir.IO IV. 1'ISSODIXI. 181 



northwest to Michigan, Minnesota and over the eastern half 

 of Canada. Known as the "white pine weevil," the eggs 

 being laid in the bark of terminal shoots, especially those of 

 saplings, the larvne burrowing under the bark, completely sepa- 

 ratin<>' it and causing the death of the terminal. Infests also the

pitch and Labrador pines, Finns ri<ii<la Mill and /' iJimnnitn 

 Ait, and the red and Norway spruces, Piccn rubcii* and P. e.ccclsa 

 L. Very injurious to the white pine, much less so to the other 

 species. 



239 (- -). PISSODES APPROXIMATE Hopk., 1911, 33, 49. 



Oblong-oval. Dark brown to nearly black, the hind spots of elytra 

 separated, the yellow one smaller, the white one extending over the second 

 interval. Beak longer and more slender than in strobi. Thorax not 

 distinctly narrower than elytra, its punctures rather coarse. Third interval 

 of elytra broad, flattened, moderately rugose. Length 4.3 6.7 mm. 



One specimen in the Stein collection, labelled Indiana. Range 

 very nearly the same as that of strobi. Attacks the same pines, 

 as does the latter, and also the yellow, red, scrub and table moun- 

 tain pines, Finns ecJtin<it<i Mill. P. resinosa. Ait., P. rirginiana 

 Mill, and /-*. pnngcns Michx. ; occurring not in the terminal shoots 

 but in the thick bark on the trunks, stumps and logs and the base 

 of saplings. Commonly confused in collections and literature with 

 strobi, but distinguished by its average larger size, the sides of 

 elytra more narrowed behind and their spots always smaller. 



240 (- -). PISSODES XEMOREXSIS Germ., 1824, 318. 



Oblong. Pale brown to nearly black, the hind spots of elytra much as 

 in strobi but slightly smaller, the white ones extending to the first interval. 

 Beak slender, distinctly longer than thorax in both sexes. Elytra as wide 

 at base as thorax, the third and fifth intervals rather narrow and strongly 

 elevated. Length 4.9 7.7 mm. 



Duuedin, Fla., Feb. 2(>. Clayton, Ga., June. A southern 

 species, ranging from Maryland, Kentucky and southern Missouri, 

 south to Florida and west to eastern Texas. Occurs on the yellow 7 , 

 scrub, long-leaved and loblolly pines, attacking the thick bark 

 on trunks of dying and felled trees, stumps, base of saplings, etc., 

 but apparently not especially injurious. This species was long 

 confused with P. strobi, but has much longer and more slender 

 beak, and a different range and habits. From <i/>]>r<>.rintatiis it 

 may be known by its longer beak and by the sides of elytra more 

 distinctly converging behind the base. Treated as a synonym of 

 strobi in the Biologia.
