Zett., the latter a species new to American lists. Other interest- 

 ing Diptera were Chrysofs nigrifcs Zett., Tabanus septen- 

 trionalis Loew, Thcrcva melanoneura Loew, the only represent- 

 ative of this family in the entire collection, and Scatophaga 

 frigida sp. nov. Coq. 



Coleoptera were quite rare, except Lcptalia macilenta Mann., 

 which occurred in vast numbers on the umbels of Heraclcum. 

 Two weevils were collected which proved to be new to the 

 Alaska fauna — Orckestes rujifcs Lee. and Sitoncs tibialis Hbst. 



Odonata were common about the ponds. Three species were 

 taken — Enallagma calverti Morse, Cordulia shurtlcffi Scudder, 

 and Leucorhinia hudsonica (Selys.). 



At Kukak Bay was captured the only grasshopper or mem- 

 ber of the Orthoptera observed on the Expedition. Numerous 

 individuals in various stages of growth were found along the 

 borders of a marshy pool. Mr. Caudell has determined the 

 species as Melanoflus borealis Fieber. It was already recorded 

 from Alaska. 



KADIAK 



July 20. — A brief stop at the village of Kadiak, on Kadiak 

 Island, on the return voyage, July 20, 1 enabled the writer to 

 make a hasty collection, from which it is evident that this great 

 island supports an extensive insect fauna. The presence of 

 scattered bits of forest must add greatly to the possibilities for 

 the development of insect life, giving the region an advantage 

 over the treeless country to the westward ; while the absence of 

 continuous forests relieves the insect fauna from the limitations 

 impos d by vast tracts of shade-producing conifers. 



The list of insects from Kadiak comprises 125 species which, 

 almost without exception, had already been procured at other 

 stations. Among the Diptera the only unfamiliar types were a 

 Tipulid, Pcdicia obtusata O. S., an Empid, Microj>horus atratus 

 sp. nov. Coq., and a Syrphid, Helofihilus lunulatus Meigen. 

 None of the Coleoptera call for special mention. Butterflies 

 were abundant, but of the same species as had been collected 

 at Kukak Bay, with the exception of (Ends scmidca nigra
