NOTES ON SOME HEMIPTERA TAKEN NEAR 

 LAKE TAHOE, CALIFORNIA 



BY 



EDWARD P. VAN DUZEE 



In the summer of 1915 it was my privilege to spend about 

 five weeks in the Sierra Nevada with the entomological field class 

 of the University of California Summer School at Fallen Leaf 

 Lake, Eldorado County, California. We reached Fallen Leaf 

 Lodge, our headquarters, on June 21 and left on July 31, a 

 period which covered the season of greatest abundance of insects 

 in certain of the orders, notably the Hymenoptera, Diptera and 

 Lepidoptera, and the Coleoptera were perhaps at their best before 

 we left ; the Hemiptera and Orthoptera were, however, ju.st 

 coming into season, so the material obtained in these orders was 

 but fragmentary. Circumstances were such that I was able to 

 devote much of my time to the collection of insects for the 

 University Museum, and Professor Woodworth added a number 

 of interesting forms during two brief visits to the Lodge, while 

 other members of the party turned over to me some good things 

 taken by them. Altogether over six thousand mounted insects 

 were brought home, a study of which will undoubtedly make 

 valuable additions to our knowledge of the Sierran insect fauna. 



The present paper deals with the Hemiptera taken, but. 

 owing to the earliness of the season, must be but an imperfect 

 representation of the hemipterous fauna of that portion of the 

 Sierra. Of the one hundred and forty species enumerated, per- 

 haps one-third are known to inhabit the coast region of Cali- 

 fornia and about one-fourth are common to the eastern and
