Gortyna Eupatorli, n. sp. — (The Trumpet Weed Borer.) 

 Primaries dark brown, with a sliglit sprinkling of gray. The most 

 conspicuous mark is the t. p. line, which is double, runs outwardly oblique 

 to the subcostal nervure, then turns at a right angle and runs almost 

 absolutely straight and parallel with the apical half of the outer margin to 

 the inner margin. In Type No. i this line is as straight as if ruled with 

 a ruler, but in the two specimens reared by me it is not quite so sharply 

 defined. This line is bordered outwardly wich ash-gray, witli a grayish 

 atmosphere extending outward to the submarginal line, which is irregularly 

 waved and edged outwardly with creamy scales. The other markings are 

 somewhat obscure, but the upper part of the basal line, the t. a. line, 

 orbicular, median shade and reniform show as slightly darker markings on 

 the ground colour. PViiiges dark brown, with a few creamy specks. 



Secondaries paler brown, with an obscure discal mark and veins 

 slightly darker, fringes concolorous. 



Head and thorax brown, heavily sprinkled, especially the latter, with 

 ash-gray, dorsal tuft transverse, adze-shaped, erect. 



Collar edged with ash-gray. 



Antennae grayish brown. 



Beneath paler than above, but primaries darker than secondaries, with 

 a dark median line on both wings, discal spots fairly defined, especially on 

 secondaries. Primaries have a whitish, fairly straight submarginal line. 

 Legs grayish brown. 



Alar expanse, 34-39 mm. 



Length of body, 17-1S mm. 



Types : No. i, 9 , reared by Mr. D. Brainerd, and in his collection ; 

 No. 2, ^ , and No. 3, % , reared by myself, and preserved in my collection. 



Explanation of Plate VII. 



I am indebted to Mr. Norris for taking the photographs of the moths 

 from which the halftone was made. 



No. I is a typical specimen of G. Cerussata, and may be compared 

 with Grote's figure, Proc. Ent. Soc , Phil, II, PI. IX, Fig. I. 



No. 2. — Gortyna Thnlictri, Lyman. 



No. 3.— Gortyna Euiiatorii, Lyman. 



No. 4. — Gortyna Thalictri, var. Perobsoleta, Lyman. 



No. 5 is a reproduction of the drawing made by Mr. Young to 

 illustrate his notes on the larval habits.
