there is a very narrow white terminal line. Below, the sexes are alike, gray, the 

 basal two thirds especially of both wings squammosely strigose ; outer line crenulate, 

 very irregular on hind wings but not produced into W-shape, black, red within, white 

 without. A black spot at anal angle and one between the tails, with red lunules 

 within each and a narrow black edge. Expanse 22 to 24 mm. 



Thecla oslari, new species. 



Closely allied to alcestis Edwards. It is smaller, a grayer brown 

 on the upper side, ashen gray, not brown below and the red markings 

 beyond the outer band are less developed. Expanse 16 mm. 



Two specimens, Tucson, Arizona (E. J. Oslar).

Family HESPERIID^. 



Thorybes mysie, new species. 



Male without costal fold, the anal angle of secondaries scarcely at ail produced, 

 wings broad, trigonate. Fuscous brown, fore wings with whitish subhyaline spots : 

 one in the end of cell, constricted or divided, a subcostal one above it ; two subapical, 

 one between veins 6 and 7 beyond these, one between veins 5 and 6, another between 

 4 and 5 still further out, the upper one sometimes wanting ; a large one between veins 

 3 and 4 less far out, a still larger one between veins 2 and 3 slightly constricted and 

 in an oblique line with the spot in the cell and on costa ; a small one below vein 2 still 

 further out and forming part of this straight line of spots, sometimes wanting. Fringe 

 light fuscous. Fore wings below with the spots repeated, margin washed in purplish 

 and spotted in fuscous. Hind wing purplish fuscous, two submacular bands of 

 brownish, black edged, conjoined spots, the outer followed by a diffuse light band. 

 Expanse 37 to 40 mm. 



Described from two specimens, Patagonia Mountains, Arizona 

 (E. J. Oslar). 



Type. — No. 7737, U. S. National Museum. 



Allied to T. mexicaiuis Herr. -Schaeff. and with much the same 

 style of markings. It is, however, larger, without dark edging to the 

 pale spots which are less whitish and the under side of the hind wings 

 is marked much as in PJioedinus caiciis Herr. -Schaeff. with distinct, 

 well-contrasted markings, not in the obsolete manner of T. mexica?iies. 



Family NOCTUID^. 

 Polia maxima, new species. 



Nearly allied to Folia acera Smith, of which it may be a local 

 form. It is, however, much larger and very distinctly marked. The 

 markings appear to be the same as in acera, the $ type of which is 

 before me. This specimen is old and worn, while the $ maxima is 

 very fresh.
