114 ENTOMOLOGICAL NEWS. [April, 'O2 



2. Hetaerina tricolor Burmeister. 



Youghiogheny River, just above Ohio Pyle, September 2, 

 1901. Seven specimens were taken. They are more wary and 

 stronger of flight than H. americana. They were usually 

 found resting on bushes overhanging rapids. 



During the day when the two above records were made I 

 took 29 specimens of Boycria vinosa. Most of these were 

 males. This species flies very low, just along the water's edge, 

 stopping to inspect every nook and crevice among the rocks. 

 I found it only along the ripples. It is not very wary, but 

 its irregular flight makes its capture rather difficult. 



Notes on Collecting Coleoptera in Wyoming and 



Utah. 



Bv W. KNAUS, McPherson, Kansas. 



A ten days' trip along the Union Pacific and Oregon Short 

 Ivine railways through Wyoming and Utah, as far as Salt L,ake 

 City, last June, yielded results in an entomological way that 

 may prove of" interest to workers in this line of Natural History, 

 and will thus serve as an excuse for presenting these observa- 

 tions to the public. 



I left McPherson June igth, and on the 2ist, in the afternoon, 

 was in L/aramie, Wyo., situated in the beautiful valley of the 

 same name. It would seeem almost a misnomer to speak of it 

 as a "valley" as the elevation is quite seven thousand feet; 

 but the snow capped mountains looming up to the southeast, 

 south and southwest, serve to remind one that ,he may be 

 seven thousand feet high and still be in a valley. 



A day at Laramie was spent in collecting Coleoptera and 

 mosquito bites along the L,aramie River, from a point south of 

 the city to the soda works a mile and a half north, and at, and 

 near two alkali ponds northeastward, and near the edge of the 

 city. Over all this territory the grass was full of mosquitoes 

 of large size, having an appetite most voracious. While col- 

 lecting a half do/en Coleoptera you would be forced to kill, in 

 self defence, from twenty-five to fifty mosquitoes ; thus making
