THE CANADIAN ENTOMOLOGIST. 179 



The fringes are gray and flecked with brown. The hind wings and 

 abdomen above are silvery gray, and the under side of the hind wings is 

 the same as above, but reticulated with darker gray on the costa and the 

 outer border. The under side of the fore wings is somewhat darker than 

 the hind wings and shows the markings of the upper side to some extent. 

 Described from one specimen taken in Hamilton, Ontario, and one taken 

 at light in Amherst, Mass., Sept. i8, 1887. 



I take great pleasure in naming this beautiful insect for Miss Rose 

 Linda Davis, who has ably assisted me in my entomological work for the 

 last three years. 



NEW FORMS OF ICHTHYURA. 



BY HARRISON G. DYAR. 



Ichthyuj-a ?m{ltnotna n. sp. 



Ground colour of primaries dark "ecru drab" (Ridg. iii., 21, * but 

 much darker), heavily irrorate with "clove brown" (Ridg. iii., 2.) scales 

 which almost entirely obscure the ground colour at the basal portion of 

 the wings as well as outside the third and fourth lines. First (basal) 

 transverse line faintly yellowish, inwardly arcuate from internal margin to 

 median vein, then rectangularly bent towards the base and following the 

 median vein for about 1.5 mm., when it is again bent at right angles and 

 proceeds straight to costa. Second line before middle of wing, consisting 

 of a line of the ground colour bounded outwardly by a narrow clove brown 

 line, straight across wing from internal margin to costa. Third line slightly 

 yellowish, outwardly arcuate from internal margin to vein 2, just beyond its 

 origin, faint across cell, consisting there of a line of the ground colour appar- 

 ently running straight to costa. Fourth line starting on internal margin, 

 near origin of third line, and running slightly obliquely, but nearly straight 

 to the costa subapically. It is undulated across the subcostal nervules, but 

 is not broadened at costa nor marked with white, being uniformly yellow- 

 ish. Outside this line subapically, an irregularly triangular rusty brown 

 patch, and another fainter patch on the middle of external margin. A 

 submarginal row of clove brown spots, distinct only below vein 2, being 

 elsewhere lost in the general dark shading of the terminal half of the wing. 



Thorax dark gray ; the vertex of head and central thoracic patch, 

 deep blackish brown. Abdomen, secondaries and whole under surface,
