ENTOMOLOGICAL RESULTS (1): 



THE TENTHREDINOIDEA.

 upon him of securing as large a representation as possible of 

 the insect fauna of the regions visited. Fortunately the condi- 

 tions were more favorable than is usually the case in the ex- 

 ploration of these northern latitudes. Every facility that expe- 

 rience and forethought could suggest had been provided, and 

 the work was further facilitated by the careful organization of 

 the party. Moreover the labors of the collector were only 

 slightly interfered with by unpropitious weather, which is the 

 more remarkable in a region notorious for its excessive hu- 

 midity and long continued rains. 



Recognizing the fact that almost nothing was known con- 

 cerning the insect fauna of Alaska outside of the orders 

 Coleoptera and Lepidoptera, a special effort was made to secure 

 representatives of groups which, from the small size or obscure 

 habits of their members, had not hitherto been collected in the 

 Territory. This endeavor was so successful that the resulting 

 collection contains by far the most extensive general series of
