5. LIBELLULA SATURATA Uhler. 



Observed. 



6. SYMPETRUM CORRUPTUM (Hagen). 



Common as usual. 



7. BRECHMORHOGA MENDAX (Hagen). 



This graceful species was present here. In the course of the day's 

 collectmg I saw not less than a dozen individuals. These usually 

 had short beats in the shade of the occasional large willow trees that 

 grew on the gravel beaches. Several were caught. 



8. TRAMEA LACERATA Hagen. 



Several were caught among the willows in the mouth of the canyon. 



FRESNO BEACH, FRESNO COUNTY, CALIFORNIA. 



On September 5, 1914, the species m the following list were taken 

 at Fresno Beach, a pleasure park 12 miles from Fresno. Here, 

 excepting Hctaerina americana (Fabricius) and Sympetrum corrup- 

 tum (Hagen), which were caught along the sandy banks of the river, 

 the entire list was taken around a back-water slough near the river. 

 This swarmed with pond sj^ecies, though the water was thick with 

 algae and almost entirely covered with duckweed. 



1. HETAERINA AMERICANA (Fabricius). 



Common along the willows overhanging the river. 



2. ENALLAGMA CARUNCIILATUM Morse. 



Common about the slough. 



3. TELEBASIS SALVA (Hagen). 



This small bright red s])ecies was very abundant over the edges of 

 the slough. They flcW about quite commonly in pairs. The female 

 oviposited while the male held her. 



4. ISCHNURA CERVIILA Selys. 



Common. 



5. ISCHNURA PERPARVA Sclys. 



Common. 



6. CELAENURA DENTICOLLIS (Burmeister). 



Common and associated with Telehasis. 



7. ANAX JUNIUS (Drury). 



This species was abundant and its habits more fully observed than 

 I had been able to observe them elsewhere. The male seized the 

 female on the wing and retained his hold on her head while she 

 oviposited. The pair would alight on the floating masses of algae. 

 The female would bend her abdomen down and forward making 

 fi'om three to ten thrusts in the loose mass of algae whereupon the 

 ])air would fly to another place. Apparently the eggs were merely 

 extruded among the filaments of the algae. 



8. AESHNA MULTICOLOR Hagen. 



Common as usual.
