the female is more strigated and there is a tendency for the shading 

 to form a more distinct extradiscal band than in the male. On 

 the hind wing, however, the clouding never forms a band to the 

 margin of the wing. 



This species bears a slight resemblance to snoviata Packard 

 and puertata Grossbeck, but differs from both in the straight extra- 

 discal line on both fore and hind wings and in the marginal band 

 beneath. 



I take pleasure in naming this species after Mr. George H. 

 Field, who has done so much to advance our knowledge of California 

 Lepidoptera. 



Holotype — cf , La Puerta Valley, Calif., July 11; in my collec-

 received through the kindness of Mr. Field. 



Allotype— 9, La Puerta Valley, Calif., July 11, in Mr. Field's

Paratypes — cf's and 9 's, from same locality, in Mr. Field's 

 collection and my own. 



Macaria grossbecki, n. sp. 



Male — Expanse 22-23 mm. Head, antennae and legs fawn- 

 coloured. Thorax and abdomen brownish ashen, darker than in 

 fieldi, with a sufTused appearance, without conspicuous lines or 

 markings as in the other species. Intradiscal line faint, pale orange, 

 shaded with black; mesial space heavily strigat:d, as in the entire 

 wing; not paler, as \n fieldi. Discal ringlet clear black, with paler 

 centre. Extradiscal line faint, blackish, with slight clouding. 

 Veins with faint minute dots, fringe fuscous. Hind. wings of the 

 same colour as fore wings, with a trace of an irregular extradiscal 

 ochreous line, blackish-shaded. Beneath paler than above, the 

 discal ringlets showing on all the wings. No markings apparent, 

 except the extradiscal brown marginal band, which shades to the 

 outer margin; in this respect differing horn fieldi. 



Female — Similar above to the male; beneath much lighter 

 basally, where it is strigated, a brownish band running extra- 

 discally solidly to the outer margin. 



Viewed from beneath, this species has somewhat the appear- 

 ance of puertata Grossbeck; but above, it appears very different
