podia), but with the apex sharper, median sliade fartlier from the cell-spot, post- 

 median more dentate and less curved, underside redder. Cyphopteryx incurvaria 

 Guen. (Spec. Gen. Lip. ix. 404 ; Oberth., Et. Lep. xii., fig. 3339) looks, from the 

 figure, almost like a secondary sexual modification of this species. Diihecodes 

 ( = Mnesithetis) rufipuncta Warr. (Proc. U.S. Nat. Mus. xxx. 452) must also be 

 very similar, except for the reddish cell-spot, but Dr. Dyar (iu Utt. August 7th, 

 1917) writes that in that species "the tibia (,J) is slender, with a small pair 

 of spurs." 



22. Semaeopus offlexa sp. nov. 



<J, 29 mm. Considerably larger than deflexa Warr. (Novitates Zoologicae, 

 vii. 152), hindwing quite differently shaped, the termen being much more 

 strongly convex, noticeably bent in the middle. Ground-colour much lighter 

 and brighter, inclining to heliotrope-purple. 



Forewing with the postmedian line not quite as strongly bent as in deflexa, 

 othenvise similar ; the rufous edging of the lines stronger ; termen without 

 black line, the white dots at the ends of the veins rather conspicuous. Hind- 

 wing with the line straighter than in deflexa ; termen marked as on forewing. 



Calama, Rio Madeira, below Rio Machados, August — October 1907 (W. 

 Hoffmanns). Type in coll. Tring Museum. 



23. Semaeopus ascia sp. nov. 



(J, 19-20 mm. ; ?, 20-23 mm. 



Forewing vinaeeous cinnamon, commonly more vinaceous in distal area, or 

 sometimes throughout ; distal area often with some blackish dusting, which 

 sometimes forms ill-defined clouds just beyond the postmedian line ; markings 

 nearly as in oaxacana Schaus [Tr. Amer. Ent. Soc, xxvii. 189), and osteria Druce 

 (Biol. Centr.-Amer., Lep. Het., ii. 537, t. 99, fig. 9), but with the lines nearer 

 together, the postmedian rather straighter still, the median shade entirely want- 

 ing ; terminal dark dashes weaker, sometimes almost obsolete. Hindwing 



similarly without meditin shade, the postmedian running straighter across the 

 wings, nearer to the cell-mark (in the species named curved more or less parallel 

 with termen) ; terminal dark dashes as on^ forewing. 



Ciudad Bolivar, Venezuela, April — June 1898 (S. M. Klages). A short 

 series, including the tj-pe (May 9th) in coll. Tring .Museum. Also in the same 

 collection from Surinam, N. Argentina, and Paraguay. 



I cannot find that tliis widely-distributed little species has ever been named. 

 Warren labelled it eigillata Walk., or on one occasion decalvaria Moschl. 



24. Semaeopus hoflmannsi sp. nov. 



(J, 27 mm. Head dull red ; crown somewhat niLxed with black. Thorax 

 concolorous with wings ; abdomen slightly paler. 



Forewing rather broader than in the rest of the group (Dichromatopodia 

 Warr.), apex rather blunt, termen gently curved, not very oblique ; uniform 

 light chocolate ; lines fine, pale buff ; antemedian apparently angulated sub- 

 costally, but almost obsolete anteriorly, very slightly incurved between SC and 

 SM', nearly parallel with postmedian ; cell-spot small, not elongate, vliito with 

 a few grey scales and a slight blackish mark proximally ; postmedian almost
