year before, by a Brooklyn, N. Y., entomologist, who found them 

 in Southern Arizona. The moth is similar in size, form and 

 general color to the cecropia. The extended wings measure 

 about five inches from tip to tip, and each one is ornamented in 

 the centre with a large, transparent, triangular spot. A white 

 band crosses the body just back of the thorax and extends later- 

 ally around the abdomen. 



If your entomologist had only gone to Mexico a year sooner 

 he might have been the first to find this magnificent insect. Ex- 

 cept certain unpleasant domestic pests these were the only insects 

 met with. Beetles were still in winter quarters and so secluded 

 that it was impossible to ferret them out. 



But I turn to the insects in which we have a more practical 

 interest. In the summer of 1881, the Linden or Basswood trees 

 all around Minneapolis were attacked in force by a leaf-rolling 

 larva that had never been seen here before. Its ravages were so 

 serious on some trees as not only to greatly disfigure them and 

 check their growth, but to actually endanger their lives, and 

 there was scarcely a tree that was not more or less infested. The 

 leaves were slit first aci'oss from one edge beyond the mid vein 

 and then in a curve toward the tip but not quite severed. This 

 part was neatly rolled into the form of a cone-shaped bag fastened 

 with bauds of silk to keep it in shape and had both ends neatly 

 tucked in. The mischief maker could be found, on unrolling 

 this odd little case, securely housed in the centre, engaged in 

 dining on the inner walls of his house. He was a pea-green, 

 stout, worm-like fellow with jet black head, collar and thoracic 

 legs. When he had gained his full size he drew a part of his 

 case closer around him, lined it with silk and changed to a slen- 

 der brown chrysalis. 



I neglected to gather any of these cases early in August and 

 when I did collect later in the month, all the moths had escaped. 

 A large proportion of the pui^ae had evidently been destroyed 

 by parasites. The work of the latter, aided perhaps by climatic 

 conditions, must have been unusually thorough, for during the 

 following summer I could not discover a single rolled leaf even 

 on the trees that were most abundantly infested the year before. 

 Nor did any appear in 1883, but last sumni(?r they were again 

 on hand in moderate numbers. 



In the fall of '82 Prof Feruald discovered what is undoubtedly 

 the same insect on the Basswoods around Bangor, Maine, and he 

 was fortunate enough to get the moth which proved to be a
