156 THIRTIETH REPORT ON THE STATE MUSEUM. [44] 



from quite a distance beyond the boundary of the garden. 

 Farther experience has shown that a larger quantity of the 

 bait might have been advantageously used in extending it to 

 the fences inclosing the garden, and that the results to be ob- 

 tained by this method of collecting, are to be measured by the 

 extent of the locality, the area sugared, and the frequency 

 of its repetition, provided the region be one where the Npctuidse 

 occur in reasonable abundance. 



As directions for sugaring have already been published,* 

 they will not be repeated here, but will be given in a paper 

 in preparation, in which the various methods employed in 

 the attraction of Lepidoptera will be detailed. 



A brief account of the collections herein noticed was pre- 

 sented at the meeting of the American Association for the 

 Advancement of Science, held at Detroit in 1875. Several of 

 the members present were stimulated to test for themselves 

 the recommendation made of this simple and most valuable 

 means of enlarging their cabinets and extending oar knowl- 

 edge of an interesting and important class of insects. In 

 every instance, it is believed, the results were highly gratify- 

 ing.
