 Oporinia autumnata hensliawi var. nov. 



This race has been going under the name of dilu- 

 tata Schiff in the east- It is of a pale ashen white 

 with irregular zig-zag lines on primaries. Head and 

 thorax, ashen white, body slightly ochreos ; palpi, 

 short, rather ochreos. Basal line starts from costa 

 at right angles to medium vein, then runs straight to 

 inner margin ; following this are three or four irregu- 

 lar brown lines, forming points on medium and mar- 

 ginal veins. The intra discal is a broad line shaded 

 widely with brownish, starting from costa, it makes 

 a strong angle inward, then outward, to medium vein 

 forming a point. Below medium vein it angles back 

 td marginal vein, then to inner margin. The mesial 

 space is white with discal spot of black. The extra 

 discal line is broad and shaded as the intra discal, but 

 bends outward below costa and above discal spot, 

 then runs straight down in scallops to inner margin. 

 Beyond the extra discal line is a narrow, irregular, 

 whitish space, with a zig-zag line running through it. 

 The outer margin is fuscous with white line running 

 through it. Double black points at end of veins, at 

 base of fringe, which is checkered black and white. 

 Hind wings, pale ashen, with traces of five or six 

 scolloped brown lines, the sub-terminal being heavi- 

 est, pointed inwardly on the veins. The discal spot 

 is very faint on one specimen. This race approaches 

 auti{m>iota of Europe very closely in markings. The 

 more trongly angled extra discal line of henshaici 

 will separate them in my series, but this may not 

 hold. I have placed this as a race of autumfiata as 

 the genitalia show no relationship to dilutata, it may 

 later prove to be a distinct species. The octavels of 

 henshawi are wide apart and the papillae are very 

 small, not raised up as diluta or autumnata- The 

 costa of the valvas has a distinct arch in the middle.
