leff of Brookline, a fellow-studeut in Entomology. Mr. Shurtleff was 

 a most enthusiastic lover of nature, and specially interested in study-

 rare insects, including several unique species mentioned in this paper, 

 has been placed in the collection of the Boston Natural History Society. 



ISA nov. gen. 

 Front of the head full and Si(uare. Antennae simple. Palpi porrect, 

 not surpassing the front ; third joint very small, .icutely conical. Body 

 rather stout. Fore wings a little more than one-half as wide as long; 

 costa more convex than usual in the middle, apex a little produced, 

 outer edge equaling in length the inner edge, below the apex slightly 

 excavated, thence very oblique to the internal angle. Tnner margin 

 short, convex in the middle. 2nd subcostal turning towards the costa 

 at an angle of 45° from its nervure ; upper branch of .3rd short and 

 parallel with it, but the distance between the two is much greater than 

 usual. The apical interspace is shorter and more broadly triangular 

 than usual. 1st median nervule is more continuous with its main ner- 

 vure than usual. Costa of the hind wings more convex than usual. 

 Internal angle distinct. Outer margin rounded, bent slightly in the 

 middle. Legs stout, densely pilose externally. Inner tibial spur the 

 longest ; tarsi stout and thickly scaled.

TORTRICIDIA nov. gen. 

 Front square, but a little higher than wide. Antennas thick at the 

 base in both sexes, simple. The scales spreading a little at the end of 

 each joint. Palpi long, slender, ascending, 2nd joint long and slender, 

 3rd continuous with it, either long and slender, or shorter and conical. 

 Primaries one-half as wide as long ; costa convex, apex rotund pointed ; 

 outer margin oblique ; fringe gi-adually becoming wider towards the 

 internal angle. 1st subcostal nervule nearly as long as the costal ner- 

 vure. 2nd s. c. parallel with the first ; .3rd s. c. approximate and nearly 

 parallel with the costa. A distinct discoidal fold terminates between 

 the 5th s. c. and 1st median. Hind wings broadly subtriangular ; costa
