near the base, and three-fourths as long as the 

 costa of the primaries. The legs are long, 

 naked, the second pair with a long slender 

 terminal spur, the third pair with double sub- 

 terminal and double terminal spurs, likewise 

 slender, the inner member of each pair being 

 longer than the outer. The abdomen is much 

 produced beyond the inner margin of the 

 secondaries, slender, and lightly tufted with 

 long hairs at the tip. The vestiture of the 

 abdomen is smooth, appressed. The patagia 

 are relatively long, covering the insertion of 

 both wings. The primaries are narrow, 

 elongated, slightly curved on the costa, 

 evenly rounded on the outer margin, and 

 bilobed on the inner margin, the 

 first lobe being just beyond the base, 

 the second about the middle of the 

 wing. Beyond this second lobe, the 

 inner margin of the wing is straight. 

 The secondaries are subtriangular ; 

 the costa is arched beyond the base, 

 pointed at the apex, nearly straight 

 along the outer margin, and slightly 

 curved on the inner margin. In the 

 primaries the internal vein has two 

 branches, the lower one extending 

 from the base to the outer edge of 

 the second lobe of the inner margin, 

 the upper extending to the outer 

 angle. The radial springs from the 

 middle of the discocellulars. There 

 is an areole at the upper angle of the cell, 

 from which veins six to ten spring. Veins 

 seven and eight are emitted from nine beyond 

 the upper angle of this areole. Vein eleven is 

 given offbeyond the middle of the cell. Vein 

 twelve is straight and terminates upon the 

 costa three-fourths of the distance from the 

 base. In the secondaries the inferior vein 

 has two branches, the innermost terminating 

 on the anal angle, the outermost widely sep- 

 arated from it, the outer margin being 

 slightly lobed between the extremities of these 

 veins. The radial is given off from the mid- 

 dle of the discocellulars, which form an angle 

 with each other pointing inwardly. Veins six 



and seven are stalked. Vein eight curves 

 downwardly to the upper margin of the cell 

 near the base, and then diverges widely and 

 terminates upon the costa a trifle before the 

 apex. Type Dinotodonta longa, Holl. 



This genus shows in the neuration affinity 

 to the Notodontidae, but together with the 

 two immediately subsequent genera is in my 

 judgment more properly referred to the 

 noctuids, the simple antennae and the long 

 legs being more characteristic of the noctuids 

 than of the notodonts, although the genus 

 Scrancia, which I have referred to the noto- 

 donts, in its neuration comes very near this 

 and the two following genera. 



Dinotodonta longa, Holl. (J , j. 



196. D. longa, sp. nov. J. Palpi, head, 

 collar, and thorax dark brown ; upper side of 

 abdomen fuscous ; lower side of thorax and 

 abdomen and the legs paler. Primaries on 

 the upper side pale vandyke brown, trav- 

 ersed by a broad band of dark vandyke brown 

 beyond the middle, which is defined exter- 

 nally and internally by heavy dark brown 

 lines, which are produced on the nervules, the 

 outermost very irregularly curved and fusing 

 with a dark brown ray, which extends from 

 the apex inwardly. There is a dark vandyke 

 brown basal shade bordered externally with a 

 curved sub-basal dark line. The inner margin 

 where lobed is dark like the basal area. The
