409 



Georia. Known as the 



half. Thorax broadly constricted in front, 

 sides rounded on basal two-thirds, disc 

 coarsely, rugosely punctured, with a short 

 carina before the middle and four small 

 tubercles. Elytra with rows of large 

 quadrate punctures; alternate intervals 

 strongly costate, third and fifth interrupt- 

 ed, each with a high median costa. Ven- 

 tral segments sparsely punctured. Length 

 5 7 mm. (Fig. 104.) 



Lake, Hamilton and Posey coun- 

 ties, Ind., scarce; May 12 July 4.

Closely allied to juglandis. Thorax with a compressed line each side 

 of yellow and gray hairs; elytra with posterior band broad, narrower to- 

 ward the sides, composed of pure white or grayish-yellow hair, and a con- 

 spicuous white spot at base of third interval. Beak more stout, longer 

 than thorax, curved, deeply striate, carinate and punctate. Crest of fifth 

 interval of elytra less elevated and scarcely separated from the subbasal 

 part of the costa. Ventral segments coarsely and rather densely punctured. 

 Length 3.5 4.7 mm. 



Marion, Dubois and Perry counties, Ind., scarce; May 12

Dark brown varied with black; pubescence brownish-yellow, forming 

 a curved bifurcate line each side of thorax and a post-median elytral band 

 composed of yellow and white hairs; a conspicuous white line at base of 

 third interval. Beak stout, curved, slightly longer than head and thorax, 

 strongly striate and punctured. Thorax as wide as long, sides feebly round- 

 ed, disc strongly constricted near apex, carinate in front of middle, coarse- 

 ly and roughly punctate. Crests of elytra more abrupt, the median ones 

 more prominent than in juglandis and aTbicinctus. Ventral segments 

 coarsely and densely punctured, the fifth with two setae-bearing tubercles. 

 Length 4.56.5 mm. (Fig. 105.)
