530 MR. H. DRUCE ON NEW HETEROCERA. [May 19, 



Mennis, Walker. 

 Mennis FiDENTiA, sp. 11. (Plate XXXIII. fig. 1.) 



Primaries brick-red, with the apical third of the wing sooty black : 

 secondaries brick-red, bordered with black from the apex to the anal 

 angle ; the underside the same as above. Head, thorax, and 

 abdomen black ; antennae, palpi, and legs brownish black. 



Expanse I5 inch. 



Hah. Colombia, Antioquia {Salmon). 



A well-marked and very distinct little species, not nearly allied to 

 any with which I am acquainted. 



Mennis herona, sp. n. (Plate XXXIII. fig. 2.) 



Primaries from the base to the middle dull red, from the middle 

 to the outer margin semihyaline smoky black : secondaries dull 

 red, broadly banded with black at the apex, the outer and inner 

 margin narrowly streaked with black. Head, thorax, and abdomen 

 brownish black ; the antennae and legs black. The underside the 

 same as above in all respects. 



Expanse 1 inch. 



Rab. Ecuador, Sarayacu {BucHey). 



A pretty little insect allied to the preceding species, from which 

 it is at once distinguished by its much more slender form and 

 different position of the red markings. 



Mennis ficulnea, sp. n. (Plate XXXIII. fig. 3.) 



Primaries semihyaline, clouded with bright red from the base to 

 beyond the middle, the apex and outer margin to the anal angle 

 broadly bordered with semitransparent black ; from anal angle along 

 the inner margin to near the base slightly clouded with greyish 

 white : secondaries bright red, somewhat transparent, broadly 

 bordered with black from the apex to the anal angle, where the 

 border becomes quite narrow. Head, thorax, and abdomen greyish 

 black ; antennae black. 



Expanse Ig inch. 



Hab. Ecuador, lutaj (BucTcley). 



This species is very distinct, but comes nearest M. fidentia. 



Mennis hagno, sp. n. 



Primaries shape and form of M. ficulnea, but smaller and the red 

 colour of a much more orange shade, the outer half of the wings 

 being dove-colour instead of black ; the secondaries differ in the 

 same way as the primaries, the dove-coloured borders being wider 

 than in ficulnea. Head and thorax black ; tegulae red ; abdomen 

 black, banded with dove-colour ; antennae and legs black. 



Expanse 1| inch. 



Hab. Ecuador, Intaj {Buckley). 



This species is easily distinguished from its allies by the dove- 

 coloured margins of the wings.
