NO. 2192. DRAGONFLIE^, CALIFORNIA AND NEVADA— KENNEDY. 605 



3. HYPONEURA LUGENS Hagen, 



Very abundant in the mouth of the canyon. In ovipositmg the 

 male does not stand erect while attached to the female as does the 

 male Argia. Oviposition is in any green branch lying in the run- 

 ning water. 



4. ENALLAGMA CARUNCULATUM Morse. 



Occasional. 



5. ENALLAGMA CYATHIGERUM (Charpentier), 



Occasional. 



6. ZONIAGRION EXCLAMATIONIS (Selys). 



One pair taken at the canyon. 



7. ISCHNURA CERVULA Selys. 



Scarce. 



8. ISCHNURA PERPARVA Selys. 



Several observed. Not as common as usual. 



9. PROGOMPHUS BOREALIS Mc Lachlan. 



Several males were taken. Difficult to approach. 



10. OPHIOGOMPHUS BISON Selys. 



Found on the same pools as the preceding but much less wary. 



11. GOMPHUS SOBRINUS Selys. 



A number were seen where the river ran through the city park. 

 Evidently its season was almost over. 



12. OCTOGOMPHUS SPECULARIS (Hagen). 



Imagoes of this were not seen but the exuviae were very abimdant 

 in the mouth of the canyon. 



13. AESHNA MULTICOLOR Hagen. 



Not as common as usual. 



14. MACROMIA MAGNIFICA Mc Lachlan. 



Common. I took 12 of these in less than an hour where they 

 were beating up and down a narrow lane. In the late afternoon 

 this species loves to hunt away from the water. 



15. LIBELLULA SATURATA Uhler. 



Several seen. 



16. SYMPETRUM PALLIPES (Hagen). 



Not common. 



17. BRECHMORHOGA MENDAX (Hagen). 



Several individuals of this graceful species were seen. Two males 

 and a female were taken. The males were taken while flying on 

 short beats over the stream. The female was captured while cut- 

 ting S's and figure 8's through a swarm of small Diptera. She was 

 indifferent to several passes I made at her before I succeeded in 

 netting her. This species is the most graceful on the wing of any 

 odonate with which I am familiar. Frequently they fly with a 

 swmging mayfly-hke motion. In the heat of the day they floated 

 around among the tree tops.
