the interior points of St. Charles and Liberty. This also is a 

 high country and it was early for good collecting. The next 

 and concluding institute was at Malad City on July 3, and 

 from here my trip of investigation began. I had collected so 

 far only the following Diptera of special interest: 



At McCall, Idaho, on Payette Lake, Asemosyrphus mexi- 

 canus. 



At Council, Atherix vanegata. 



At Boise, Heteropterina nasoni and n. sp. 



At Soldier, Tab anus phaenops. 



At Bellevue, Camp sic nemus thersites, Dolichopus coquilletti, 

 Chrysopila tomentosa. 



At McCammon, Pclina truncatula, Tephritis clathrata. 



On the roundabout railroad trip into Malad, a day had 

 been spent on a side trip to the Utah Agricultural College at 

 Logan; while awaiting the train at Cache Junction, I collected 

 Dolichopus amnicola and Hydrophorus gratiosits Aid. In 

 Logan I found Cliiroinyia (Scyphella) flava common on a 

 stable window. 



At Brigham City, Utah, on July 4 and 5, I spent the avail- 

 able time at Box Elder Lake, an expanse of brackish, shallow 

 water about two miles north of town. On the way thither 

 along the railroad were great quantities of parsnip in bloom. 

 On these I got three species of Thereva and specimens of 

 Helophilus siinilis and Sarcophila (Paraphyto) opaca. Along 

 the shores of the lake or pond I found a new species of Lisp a 

 (described in a forthcoming paper), also Ephydra sub opaca, 

 which breeds in the salt waters ; in the adjacent grasses along 

 a waste water ditch occurred Melieria occidentalis and a new 

 species of Pelastoncunis, while I was attacked by Chrysops 

 discalis, fuh-aster and mocrens. On the bare mud, where the 

 lake had recently dried away, there were many specimens 

 of Cicindela echo, somewhat difficult to capture from a bad 

 habit of flying a long distance when flushed; they enter the 

 shallow water fearlessly and run about in it where it is a 

 quarter or three-eighths of an inch deep, capturing some kind 

 of prey there. In this situation they are unable to take wing, 

 and I picked up a few specimens from the water in my fin-
