This table presents a very different appearance. While the observa- 

 tions of 1887 indicate the greater abundance o^/usca, those of 1888 in- 

 dicate the far greater abundance of gibbosa. It is not unnoticed that 

 these observations began later in the season. Constant cold antl stormy 

 weather in the month of May prevented the use of the trap, but the con- 

 tinuity of the dates in June 1888 is more sati.sfactory than the somewhat 

 broken series of 1887, and a comparison of the two years may be very 

 satisfactorily instituted to about the middle of |une. If the excess of 

 gibbosa as compare I with fusca in the present season is exceptional, 

 there muse have been some strong influences at work, meteorological or 

 other, to have occasioned this surprising disparity in numbers. Many 

 speculations might be indulged in but none that occur to me seem to 

 sufficiently satisfactory to warrant their presentation as explaining what 

 may be abnormal in the comparative abundance of these two species in 

 my locality the present year. 



V. 

 " With the 152 gibbosa taken on July ist, 1888, among other insects 

 I took great numbers of Crambidte. They were too numerous to be 

 counted with any reasonable expenditure of time, but I counted the con- 

 tents of a small box closely packed with them, and using this box as a 

 measure, estimated their number in excess of eight thousand.
