KEY TO SPECIES OF CROUP A. 



o. Front femora with two teeth, connected at base; pubescence of scale- 

 like hairs; form more robust. 422. XKISULOSUS. 

 act. Front femora one-toothed (Fig. 79, I.); pubescence of slender hairs;

422 (8631). ANTHONOMUS NEBULOSUS Lee., 1876, 197. 



Oval, robust. Dark reddish-brown to piceous; pubescence of rather 

 coarse, scale-like hairs of a grayish-brown or fawn color, intermixed with 

 very fine, short hairs, the pale ones forming on the elytra a broad V, its 

 apex near middle of suture, its sides extending obliquely toward humeri 

 and widened behind the latter; also a number of spots on apical half of 

 disc. Scutellum yellowish-white. Beak longer than head and thorax, 

 almost glabrous, finely carinate, rather coarsely punctate, sides each with 

 two strife. Antennas slender, inserted one-third from apex, second joint 

 of funicle twice as long as third, one-half the length of first. Thorax 

 bell-shaped, at base three-fifths wider than long, narrowed in front, disc 

 densely, deeply and rather finely punctured. Elytra oblong-oval, at base 

 one-third wider than thorax, stria? with close-set punctures; intervals wide, 

 feebly convex, finely punctulate. Length 3.7 4.2 mm. 



Common throughout the northern half of Indiana, much less 

 so in the southern counties ; May 3 June 31. Beaten from 

 flowers of Cnit<r</ns and foliage of oak. Batavia and Portage, 

 N. Y. ; May 24 July 5. Ranges from New York and Michigan 

 to Missouri. Varies in the ground color from pale reddish-brown 

 to almost black, and also in the pattern of elytral pubescence. 



423 (10,984). ANTHONOMUS POMORUM Linn., 1758, 381. 



Dark brown or piceous, clothed with yellowish-brown and grayish 

 hairs, the latter forming a median and lateral stripes on thorax, an oblique 

 band behind the middle and a triangular spot on the declivity of the elytra. 

 Length 4 mm. 



A common European species of which Dr. Diets! received a 

 single female among some specimens of iiclmlosus from Ohio. 

 Easily separated by the single tooth of the front femora. In 

 Europe it is called the "pomaclia," and breeds in the buds of 

 apples, pears and cherries, causing them to drop. 



GROUP B. 



In this group the second joint of funicle is longer than third; 

 pubescence coarse or sparse; ventral segments not very unequal, 

 the fifth somewhat longer than either third or fourth ; claws 

 armed with a long slender tooth. Three species occur in our
