more than halt the length of body, finely striate on basal half. Thorax one- 

 third wider than long, sides rounded, suddenly strongly constricted near 

 apex, disc densely rugosely punctured, the median carina distinct, nearly 

 entire. Base of elytra one third wider than thorax, strongly sinuate, hu- 

 meri rounded; strife composed of small, closely placed quadrate punctures; 

 alternate intervals finely carinate, their surface more densely pubescent 

 and with rows of very short bristles. Beneath densely, coarsely punctured; 

 last ventral with a round impression near tip. Length 5.5 7 mm. 



Putnam County, Ind., rare; May 3. Long Beach, X. Y., June 

 11. Atlantic County and Anglesea, X. J. ; May August. Eanges 

 from New York to Indiana, south to Florida and Texas. Bred 

 from the fruit of hawthorn, Cratwyus. (Hamilton.) Pierce 

 il907, 275) states that it breeds in acorns of post- and live-oaks, 

 266 larva? having been taken from 167 acorns of live-oak, Qncrcns 

 rirytnitina L. in Texas in October. The larva? entered the ground 

 mmediately, began to pupate March 15, the first adult appearing 

 April 2.

 which is seldom longer than head and thorax, striate, at least on 

 basal half, with the antenna? (except in florirluims) inserted not 

 more than one-third behind its tip.
