THE LEI'IDOPTERIST

posite discal spot there are two or three sHght serra- 

 tions; a faint basal line running straight from inner 

 margin, fading out just above discal spot where it 

 almost touches ; extra discal line curves slightly from 

 inner margin to outer, just below discal dot being 

 accentuated on the veins ; this line is followed by two 

 brownish bands with white in between, the margin of 

 wings is dusky shaded and has the usual intervenuUar 

 dots. 



Beneath the primaries are smoky gray with no 

 lines showing only the round discal spot apparent; 

 secondaries are marked the same as the primaries. 



This species is associated with inconspicua Hulst, 

 wrightiaria Hulst, formosata Hulst and agrestaria 

 Grossbeck. In general appearance it is nearest in- 

 conspicua Hulst which is said to be a svnonym of 

 aethalodaria Dyar. 



The genitalia separates this species easily from the 

 rest and is very distinct. The harpe is strongly de- 

 veloped in this species and can be made out with the 

 naked eye In wrightiaria as limited by Grossbeck, 

 the harpe is short with projecting rod, short and nar- 

 row, in inconspicua it is long, with a long narrow 

 projecting rod, in exhumata the harpe is long, with 

 long, wide projecting rod. There are other differ- 

 ences in the shape of the uncus or tegumen as some 

 prefer to call it, and in the spining of the penis. Gross- 

 beck wrote an article on this group correcting some 

 of Pearsall's determinations in the "Journal of the 

 New York Entomological Society," Volume XX. No. 

 4, page 290. December, 1912. Mr. Grossbeck. how- 

 ever, mixed this closely allied species with wrightiaria, 

 calling them all that species. This can readily be ex- 

 plained .Ts there were few collectors at that time inter- 

 ested in Geometers and without the great amount of 

 material which is available now, it was impossible to 

 see that there were to be so many closely allied species. 

 Expands 26 to 27 mm.
