THE letters addressed to the two distinguished United 

 States officials are unlike most of those we have passed. 

 Miss Ormerod writes, as usual, in courteous and even in 

 deferential terms to the two acknowledged chiefs among 

 Entomological authorities in America. The considerable 

 variety of subjects touched upon are dealt with in less simple 

 language, and minor details give place to discussions on the 

 higher polity of Economic Entomology. The letters contain 

 internal evidence of the esteem in which her work was held 

 by her correspondents.

 so very troublesome and injurious where it establishes itself 

 that I should like to place a short account of it in your 

 hands, hoping that at your leisure (I should rather say at 

 your best convenience, for leisure you have none) you may 

 kindly tell me whether you have it in the U.S.A., and, if so, 

 whether you manage to keep it in check. The caterpillars 

 were first observed in Europe in 1877 by Dr. Jul. Kuhn, of 

 Halle, doing much mischief during the process of grinding 

 some American wheat. The imagines from these larvae were 



placed by Dr. Kuhn in the hands of Professor Zeller, who
