Lake, ^larsliall, ilarion and Lawrence counties; frequent. April 

 29^July 15. Knab says of it : "This species feeds exclusively upon 

 the hazel, both in the imat;" and larval stai^es, and, as far as known, 

 it is the (inly species of CaUigraplia found upon this plant. ' ' It will 

 probably be found throuohout the State, wherever hazel oecu.rs.

 double sutural stripe on median third of elytra) is very slender, less curved 

 than usual and with its front and hind portions directed obliquely forward 

 and backward. Discal elytral spots 15 or 16 in number. Length 7-8 mm. 



Lake County; rare. ]May 25-June 3. Knab's specimens are 

 from ^Missouri, and he thinks this may be the form mentioned b\-

 mens the gi-eater part of elytral disk is bright orange red, the basal third 

 and broad outer margin golden. Punctuation of elytra distinctly coarser 

 than in rhoda and the surfai-e therefore more uneven. Tarsal claws more 

 divergent. Length G..1-8..") mm.
