54 ENTOMOLOGICAL SOCIETY 



Wings thin and translucent, brownish gray, the fore wing marked 

 with two faint, darker transverse lines, curved, the outer one somewhat 

 irregular in the upper half of its course. The large plumose antennae 

 are very prominent. Expanse, 18-19 mm. 



Four specimens, San Diego, Cal. (G. H. Field), Grapevine, 

 June 29, all males. 



Type. No. 11695, U. S. National Museum. 



I am quite in doubt about the proper family reference of this 

 genus. It falls in the Lymantriidse (Liparidse) by Sir George 

 Hampson's table if vein 5 of the fore wing be taken as nearer 

 vein 4 than vein 6, which is the case, but only slightly. How- 

 ever, there is no bar between the costal and subcostal veins 

 of hinds wing as called for by the table. The alternative posi- 

 tion would be in the Geometridse, where it would fall in the 

 Ennominae. I can not place it exactly by Hulst's table in 

 default of female specimens, but we have nothing that I know 

 of in the least like it. It looks like the Lithosian genus 

 Nudaria. 



Family NOCTUID^E. 



Subfamily AGROTIN.E. 

 Euxoa fieldii, n. sp. 



Head light ocherous gray; collar clay-color in front, with a central 

 curved black line, dark gray behind; thorax dark gray with some 

 ocherous scales centrally; abdomen pale gray. Fore wing with the 

 costa broadly pale, clay-colored in the male except for a red subapical 

 stain, infuscated on the outer half in one female, largely infuscated in 

 the other; basal space below the costa dark gray, separated by black 

 from the costal area, the black forming a triangular spot at base of 

 median vein and also on the costa in the females ; inner line forming 

 three curves, blackish, geminate, pale-filled; claviform black-outlined, 

 dark-filled, continued by a black line along submedian fold, which in 

 two of the specimens is bordered on each side by ocherous clay-color; 

 orbicular small in the male, larger and oblique in the females, clay- 

 color with a narrow black edge, the center dark-filled in the females; 

 reniform large, concave on its outer side, clay-color with a narrow 

 black edge and a concentric darker center ; cell and below to vein 2 

 black-filled, the median space below dark gray, a red tint in the male ; 

 outer line obsolete, limiting the pale subterminal space, which is broad 

 and forms rays centered by the dark veins, cut by a row of black 

 wedges resting on the pale waved subterminal line ; terminal space 

 blackish-filled; a terminal row of minute black cusps. Hind wing 

 whitish in the male with a narrow fuscous border; all fuscous in the 

 females, the fringe whitish. Expanse, 36-38 mm.
