Heliocheilus paradoxus, n. sp. (Plate 2, fig. 3 % , 4 9, 5 9, reverse.) 



9 . Entirely pale testaceous, fore wings and thorax darker, more yel- 

 lowish, hind wings and abdomen paler. 



Anterior wings palest in terminal, darkest in subterminal space, 

 which latter is bordered inwardly by the transverse posterior line, the 

 latter blackish, quite distinct, regularly dentate between darker points 

 on the veins ; reniform and orbicular spots sub-obsolete; transverse 

 anterior and basal lines obsolete; a terminal series of black dots be- 

 tween the veins ; fringes palish. Under surface whitish testaceous, a 

 large distinct black discal spot and a smaller nearer to base, correspond- 

 ing to the reniform and orbicular spots of upper surface ; a distinct 

 subterminal blackish band. Posterior wings silky pale testaceous, a 

 broad pale blackish border interrupted about the center, and a blackish 

 discal spot. Under surface very pale testaceous with a single blackish 

 mark on external margin at the extremity of the third lower discal 

 nervule. 



Legs testaceous, under surface of abdomen and thorax whitish testa- 

 ceous. Thorax and head above dark testaceous. Exp. 1.10 inch. 

 Length of body .55 inch. S . Resembles female; the membrane of 

 both cells is very sparsely covered with squammation ; the spot on the 

 under surface of the posterior wings is wanting and the whole insect 

 rather more indefinitely marked. Exp. 1.10 to 1.00 inch. Length of 

 body .5,") to .•">!) inch. 



Owing to the dissimilarity in the neuration between the sexes 1 was 

 with difficulty convinced that the single female specimen belonged 

 here. The coincident ornamentation and proportionate shape of the 

 wings — costa very full — satisfies me however that this is the case; 

 while my kuowledge of the group does not afford me a parallel to this 

 singular genus. 



EULEUCYPTERA, nov. gen. 



Allied to .1 ntha cia and Ileliothis, differing from both in the depressed 

 costal margin and more produced apices of anterior wings. The abdo- 

 men is shorter, as long as", but hardly exceeding the posterior wings ; 

 ovipositor exerted in the female. Legs without terminal spines on an- 

 terior tibiae as has been noted of Anfhacia. 



I have but a single female specimen before me, the ornamentation of 

 which is peculiar. The fore wings are lustrous satiny white with pale 

 greenish markings disposed similarly to Anihoeeia. I have been thus 

 unable to make any dissections, but can plainly perceive that the neu- 

 ration is modified from either of these genera, and have no hesitation 

 in establishing it as distinct.
