168 ENTOMOLOGICAL NEWS. [June, 



going with the wind. It was a new experience, and never before 

 or since have I seen this insect so numerous. On two occasions 

 while ascending the mountains from another view, large numbers 

 of Cantharis nuttallii were seen moving with the wind and taking 

 short flights from plant to plant. 



Returning from the trip mentioned large patches of Mertensia 

 were found, and by watching these flowers eight Hemaris bruceii 

 were taken. Several were seen on other days, but always about 

 the Mertensia. 



The third locality was north from Park City, and was a valley 

 between two mountains with a branch running east. Here, and 

 on the level top of one of the side mountains, were found Argyn- 

 nis eg Ids, cornis and meadii ; Lyctsnas heteronea. acmon and 

 stzpiolus ; Theda crysalus, calif ornica var. and behrii, Satyrus 

 charon, Chrysophanus rubidus and Pseudohazis eglanterina var. 

 nuttallii, (I call this species nuttallii on good authority, but have 

 had three different names for the variety) The typical eglan- 

 terina was seen through July and early August, and four speci- 

 mens were taken. This form of eglanterina appeared later and 

 was abundant up to the time of leaving, August igth. A tew of 

 another variety (a white form) were caught, but through a mis- 

 take every specimen was sent to other parties and I have not had 

 a name for it. 



The fourth location was the valley southwest of the city which 

 contained several large meadows partly under water with a stream 

 running through and numerous clumps of willows. Here Argyn- 

 nis eurynome (two forms) A. leto, myrina ; Lyccenas of several 

 species, two Pamphilas, Colias hagenii, Vanessa milbertii and a 

 few others were found. 



A few Coleoptera were taken, but at present cannot give names 

 of them. The beautiful Odonata were common, and a few species 

 were taken, one of which proves to be a new species. Mr. Cal- 

 vert had a description of the male in manuscript, but had not 

 seen the female. It was my intention to give at the close a list 

 of species taken, but I feel that already I have used too much of 

 the valuable space in the NEWS, and yet have not been able to 

 tell half. I can only wish that my entomological friends might 

 all have as enjoyable an excursion and try collecting in the West.
