TRIBE XIII. PRIOXOMERIXI. 



midrib, several larvae feeding side by side, making large mines 

 which inflate when dry; pupal cells are of silk and clustered to-

Short, broadly ovate. Black, moderately shining, sparsely and irregu- 

 larly clothed with long hairs, yellowish on the thorax, white on elytra; an- 

 tenna? and tarsi pale brownish-yellow. Beak gradually widened from base 

 to apex, finely striate, coarsely punctate. Thorax at base one-third wider

Lake, Steuben, Posey and Perry counties, Ind., scarce; May 

 20 June 30. Beaten from oak. Bowmanville and Evanston, 

 111., June 13 August 10. Connecticut, New York and New Jer- 

 sey, May to September. Ranges from New England to Michigan 

 and Nebraska, south to Georgia. Say records it from Knlinia 

 Jatifoliti L. ; Ulke as very common on bushes, and Harrington 

 from hickory. In fresh specimens the white hairs of elytra are 

 arranged in three more or less distinct cross-bars, median, post- 

 median and subapical, the median one very undulating.
