IO ALASKA INSECTS 



The list of insects taken at Juneau is completed by a few 

 beetles, two moths, a single true-bug, a Xeuropteroid insect 

 (Chloroperla pacifica Banks), and six species of Arachnida. 



On crossing to Douglas City, on the opposite side of the 

 channel from Juneau, a few additional captures were made, 

 mainly at the blossoms of AchiUea millefoliwn. 



MUIR INLET, GLACIER BAY 



June 912. For four days the members of the Expedition 

 explored the shores of Glacier Bay in the vicinity of the Muir 

 Glacier. On the 9th the writer formed one of a party to visit 

 a small island in the bay just opposite the face of the glacier. 

 It was found to consist mainly of glacial debris, and was thickly 

 overgrown with shrubs and flowering plants, including Sedum 

 roseum, Fragaria chilocnsis, Astragalus alpinus, Dr\as octo- 

 petala, Cham&ncrion latifolium, a species of Taraxacum, and 

 several species of Salix. 



The stones along the shore of this little island concealed 

 numerous beetles, mostly Carabidce, which scampered away 

 when their hiding places were disturbed. Among the captures 

 made in this wav were ^Xcbria mannerheimi Fisch., ^Vebria 

 mctallica Fisch., Ptcrostichus riparius Dej., Ptcrostichus luczotl 

 Dej., Bembidium complanatum Mann., Bcmbidium bimaculatum 

 Kby., Amara remotestriata Dej., and Calathus ingrains Dej. 



On the following day a part}- was conveyed in a naphtha 

 launch to a point on the shore of the bay several miles from the 

 foot of the glacier. Here a favorable collecting ground was 

 selected and the day was spent in exploring the neighborhood. 

 The soil of the entire region was evidently of recent glacial 

 origin, and in the gravelly debris a growth of coniferous trees 

 was attempting to establish itself. Dense thickets of alder and 

 willow made traveling somewhat difficult. Among the more 

 conspicuous plants in bloom were Caltha palustris, Anemone 

 multifda, Anemone parviflora, Dodecatheon pauciflorum, Aqui- 

 legia formosa, Ranunculus occidentalis, Silcnc acaulis, Arabis 

 ambigua, Petasites frigida, and Primula egalikcnsis. 



The plant whose blossoms seemed to attract the greatest 

 number of insects was Caltha palustris. The visitors were
