Three males, one female, Platte Canyon, Colorado, bred from 

 larvae on Cercocarpus parvifolius, where they occurred in small 

 proportion mixed with the dominant Teras foliana Walsingham. 

 The larvae were not differentiated. 



Type. No. 6771, U. S. National Museum. 



Mieza psammitis Zeller. 



Larvae from Mr. A. N. Caudell, Victoria, Texas. 



Larva. Head rounded bilobed, clypeus broad, rather high; paie testa 

 ceous, clypeus brownish with brown sutures and a white streak on each 

 side; retracted in joint 2, which in turn is partly retracted in joint 3. 

 Body a little narrowed at the ends, robust, flattened, shaped much as in the 

 Cochlidiidae, but less elliptical ; feet normal, weak, the planta with a single 

 row of small tufted crochets. A round, eversible area just below the 

 spiracle on joints 5 to 12 projects prominently in the inflated specimens. 

 Pale green, with longitudinal yellowish white lines, obsolete on the an 

 terior retracted segments. They are addorsal (i), two subdorsal, the 

 upper (ii) broadest, lateral, suprastigmatal, broken into spots, two sub- 

 ventral, enclosing the eversible area, the lower one much broken, and 

 scattered dots indicating two more lines above the feet. Feet all pale; 

 spiracles small, circular, brown ringed. Tubercles small and obscure, 

 with single setae; i nearly directly dorsad to ii, whitish, slightly elevated, 

 iii close to the spiracle and above it, iv and v below the eversible area, 

 separate, iv dorsad to v by the diameter of a tubercle, vi subventral bas- 

 aily, vii on the leg base; no secondary sette apparent. Skin finely 

 granular shagreened. 



Cocoon elliptical, brown, rather hard, much as in Mieza igninix 

 Walker.

THE ODONATA COLLECTED BY MESSRS. SCHWARZ AND 

 BARBER IN ARIZONA AND NEW MEXICO. 



By ROLLA P. CURRIE. 



A list of the dragonflies collected in Arizona and New Mexico

 Barber is of sufficient interest to merit publication. Collecting 

 operations extended from the last week in May till the middle of 

 August, and 172 specimens were secured, representing 24 species 

 and two varieties. Of this number one species, an Ischmira, is 

 here described as new and named in honor of Mr. Barber who
