10. GRAPHOLITHA IMITATIVA, new species 

 (Fig. 134, 298) 



A western species similar to conversana and lunatana in pattern 

 but distinguishable from both by the genitalia and the characters 

 given in the key. The sacculus of the harpe is considerably longer 

 in proportion to the rest of that organ in imdfativa than in either 

 of the other two species. 



Antenna brown. Palpus sordid grayish white more or less dusted 

 with fuscous. Head brownish fuscous. Fore wing semilustrous 

 dark brownish fuscous with a faint scattered dusting of whittish 

 scales at base, on disk and along termen; costa with four pairs 

 of short white geminate dashes, a pair before middle, two pairs 

 close together beyond middle and a pair close to apex; the first of 

 the antemedian geminations, the first and fourth of the postmedium 

 and the outer of the apical are continued for a short distance as 

 leaden metallic streaks; from mid dorsum a narrow outwardly 

 curved white geminate mark (sometimes partially divided by a 

 thin line of brown scaling) extends to middle of cell; ocelloid patch 

 consisting of a moderately long, vertical, metallic inner bar and a 

 much shorter, slanting outer bar inclosing two longitudinal black 

 dashes (in upper part of patch) and two or three small irregular 

 black dots upon a whitish or whitish ocherous ground; cilia pale 

 lustrous leaden fuscous with black basal line, outwardly finely edged 

 with whitish scaling, the black line cut below apex by an obscure 

 white spot. Hind wing dark brown, almost concolorous with fore 

 wing; cilia pale, smoky, with dark basal band and the tips of the 

 hairs shading to Avhite and with a white spot on costa close to apex; 

 veins 3 and 4 connate. 



Genitalia figured from paratypes in National Collection from 

 Coldstream, British Columbia ("31-V-21, E. H. Blackmore No. 

 378," male and San Francisco, Calif, (female). Male abdominal 

 tufts consisting entirely of fine hair like scales.
