p. 727, bnmimda, Dogn. Ann. Soc. Ent. Belg. lii. p. 266, and 

 reducta, Dogn., ibid., distinguished by the two parallel outer 

 lines ; from botydata also by its more ocbreous tone, less 

 sharp markings, more interrupted terminal line, and absence 

 of distinct dark spots in the fringe ; Dognin's species I do 

 not possess for more detailed comparison. 



Euptychopoda, gen. nov. 



Face smooth. Palpus small. Tongue present. Antenna 

 in ? subserrate, very shortly ciliated. Hind tibia in <$ 

 almost certainly aborted and without spurs, as in Euacidalia, 

 in ? with one long median spur and a pair of unequal 

 terminal. Wings long and narrow. Termen of fore wing 

 entire, or very slightly sinuate towards tornus ; of hind wing 

 strongly toothed at the vein-ends, with rounded incisions 

 between, the tooth at M 1 the strongest. Fore wing with 

 cell one-half, SC 1 from cell, anastomosing with the stalk of 

 SC 2-5 to form a single areole ; M 1 separate from R 3 ,- M 2 

 from near M 1 . Hind wing with C anastomosing at a point 

 with SC or connected by an extremely short bar, thence 

 gradually diverging, SC 2 stalked with R 1 , M 1 separate from 

 R 3 ; M 2 from near M 1 . 



Type of the genus : Euptychopoda yponomeutaria (Guen.) 

 = Acidalia yponomeutaria, Guen. 



Aspect of Euacidalia, Pack. 5th Rep. Peab. Ac. Sci. 

 p. 69, with which it has hitherto been confounded ; differing 

 in the simple areole, in the more sharply dentate margin of 

 the hind wing (suggesting a transition to the curious genus 

 Odontoptila, Warr. Nov. Zool. iv. p. 440), and in the tibial 

 armature of the $ , Euacidalia wanting the median spur. 

 The areole, however, is possibly inconstant in this genus, 

 as I have seen an unnamed species from Brazil and Paraguay, 

 extremely similar to E. caudata, and with the same tibial 

 armature, which has the areole double. 



Euptychopoda caudata, sp. n. 



? . 19 mm. — Face dark fuscous. Head and body con- 

 colorous with wings. Fore wing whitish ashy, speckled with 

 fuscous atoms, the terminal area from postmedian darker ; 

 a fuscous spot on costa before one-third, and another on SC 

 very obliquely beyond it, antemedian line otherwise obsolete; 

 a rather weak median line following the small dark cell-spot, 

 starting from a dark sput on costa and running parallel with
