Occurs in Europe and Siberia and across the northern part of this 

 continent, extending as far south as Ohio, Kansas, Missouri and Ne- 

 braska. 



The following varieties are based on the differences in elytral orna- 

 mentation : 



Elytra immaculate, Mass., Maine unnamed. 



Elytra immaculate or with two faint spots, Vancouver and California' ( Ohio ?) 



melanopleura Lee. 

 Elytra with two distinct spots or with one of them faint, Canada and Mass., Mo. 



ophthalmica Muh. 



Elytra with two bands. Wis. and Mass disjuncta /\and. 



Elytra with a median band broken and a subapical transverse spot, Colorado. 



ornatella Csy. 



The localities stated for these varieties are taken from my own col- 

 lection only and are therefore incomplete. I have not placed hyper- 

 borea Payk.; it is cited by Crotch as a synonym oi frigida. Crotch 

 uses barda Lee. for the first variety erroneously, this being a synonym 

 of C. Juliana. 

 3063. A. annectans Crutch, Trans. Am. Ent. Soc, 1873, p. 371.
