262 THE CANADIAN ENTOMOLOGIST.* 



Hadetia pausis^ n. sp. 



Ground colour powdery fuscous gray or brown. Head a little paler, 

 with a darker frontal line. Collar with a broken dusky central shading, 

 patagire with a blackish submargin. Primaries with all the usual mark- 

 ings present, but broken and not contrasting. A curved black streak in 

 the submedian interspace, from the base to the t. a. line, is the most 

 prominent feature of the wing. Basal line geminate, broken, brown, 

 reaching to the black streak, and within this is the palest part of the wing. 

 T. a. line geminate, blackish, broken, a little out-curved in the inter- 

 spaces, and moderately out-curved as a whole. T. p. line geminate, 

 blackish, very even ; outwardly oblique from costa to vein 6, then forming 

 between 5 and 6 an almost right angle, and nearly evenly oblique from 

 that point to the inner margin. S. t. line pale, very irregular and obscure; 

 broken and scarcely traceable in some specimens. A crenulated, black 

 terminal line. Fringes interlined with blackish. Little dusky rays are 

 sent into the terminal space on the interspaces, h. blackish or black 

 quadrate spot connects s. t. and t. p. line in the submedian interspace, 

 and a similar connection may be made by a narrow black line opposite 

 the cell. Claviform large, extending more than half way across the wide 

 median space ; outlined in blackish, else concolorous. Orbicular irregu- 

 lar, moderate in size, outlined in blackish, brown centred. Reniform 

 narrowed above, dilated below, and constricted in the centre ; oblique, 

 outlined in black and with a blackish central shade. A vague median 

 shade is traceable on the costa only. Secondaries smoky, paler at base, 

 with a vague discal lunule. Beneath dark gray, powdery, with a common 

 outer line and a discal lunule on all wings ; but all this may be wanting, 

 and the wings be evenly powdered. 



Expands 1.20-1.40 inches = 30-35 mm. 



Habitat : Los Angeles County, California, in June (Coquillett); San 

 Francisco, Cal. 



This species belongs to the biiiotata series, and agrees widi it in 

 wing-form. The primaries have the outer margin a little toothed ; the 

 secondaries are excised below the apex. In the eight specimens before 

 me there is little variation, the only obvious features being the black basal 

 streak and, to a less extent, the black patch in the s. m. interspace con- 

 necting the t. jx and s. t. lines. 



The genitalia of the male are somewhat complex. There is an 

 oblique triangular patch at the tip of the harpes densely set with spinules,
