^ $ . Smaller than the preceding ; of a more blackish brown color. 

 The subterminal line is inaugurated by a black shade picked out by a fol- 

 lowing clay-colored edging. The t. p. line is edged on both sides by a 

 similar clay-colored costal shade, and there is a light spot on cell in place 

 of reniform. The median shade is diffuse inferiorly. The lines are dark 

 and tolerably distinct, relieved at the middle of inner margin of second- 

 aries by a pale shade. Beneath glistening, not much paler than above.

A NEW STATE ENTOMOLOGIST FOR ILLINOIS. 



Prof. Cyrus Thomas, to whom we are indebted for six out of the eleven 

 valuable reports which have been issued by the State of Illinois on noxious 

 and beneficial insects, has removed to Washington, and Prof. S. A. Forbes, 

 of Normal, Illinois, has been appointed State Entomologst in his place. 

 We heartily congratulate Prof Forbes on his well-deserved promotion, and 

 also congratulate the authorities of the State in that they have secured the 

 services of one so competent, thorough and painstaking as Prof Forbes 

 has shown himself to be in his published papers on natural science.
