vilion is the power house, situated south of the track some five 

 hundred feet. The space between the track and this power house 

 was the scene of my collecting on the afternoons of June 26th, 

 27th and 29th. It is a flat saline beach with pools of salt water 

 near the railroad embankment, with two rivulets running from 

 a pipe line south to the pools. On the afternoon of the 26th I 

 found Cichidela hcc7norrhagica Lee. in large numbers along the 

 bed and banks of the westernmost of the rivulets, and extending 

 down to and along the edge of the pools. They were shy and 

 active and were not easily taken on an uneven surface. The Utah 

 forms vary in elytral markings vary slightly from the California 

 coast specimens. None of the black variety, pacifica, found 

 with the typical species in California, occur here. Just east of the 

 rivulet I took a single specimen of Ocindela tenuicitida Sch. I 

 had had since 1893 a single specimen of this species given me 

 by E. A. Schwarz, who had taken several specimens June 15th 

 at Garfield Beach, then the popular Salt Lake resort. Later 

 in the afternoon I worked over to the other rivulet about three 

 hundred feet east and was gratified to find a half dozen of 

 tcyiiiicinda. On the 27th my entire time was devoted to the 

 east rivulet and I found this to be the almost exclusive haunt 

 of tenuicinda, hemorrhagica frequenting it only in scattering 

 numbers. It was apparently the height of the season ior temd- 

 dnda, as two at a time, and occasionally three specimens were 

 taken at a single cast of the net. The males were smaller and 

 more active than the females, and were not averse to fierce en- 

 counters to secure favor in the female regard . They apparently 

 fed on a small Dipteron which bred by the millions in the slug- 

 gish salt streams and pools. Temddnda is a strong runner and 

 flyer, but not very shy. It is placed as a variety of the Cali- 

 fornian latcsignata Lee, but from its elytral markings, shape of 

 thorax and elytra and punctuation, I am convinced that it is a 

 separate and distinct species. 



I took a single belated specimen of Cidndela vulgaris Say, 

 its season having been over for several weeks. Associated 

 with tenuidnda and hemorrhagica I took about a dozen speci- 

 mens of Casey's echo. They are shy, active runners and quick 

 flyers, and will escape from the net if possible. It was evidently
