new Species of American Uhoyalocera. 259 



5. ItJiomia cadra. 



S . Exp. 2*2 in. Neuratlon as in I. nephele^ which it also 

 resembles in distribution of the dark and diaphanous parts of 

 the wing ; it differs, however, in having the median nervure 

 and inner half of the inner margin of the primaries, and all 

 the nervures of the secondaries, except just where they join the 

 outer margin, rufous : the diaphanous part of the secondaries 

 is also tinged with rufous. 



Hob. Panama, Rio Gatun (Ribbe). 



Mus. nostr. et Dr. O. Staudinger. 



Obs. Two specimens obtained by Hr. Ribbe agree in the 

 above characters, which seem to be sufficient to distinguish 

 the species from /. nephele^ to which it is undoubtedly closely 

 allied, and which is also found in some numbers in Central 

 America, as far north as Costa Rica. 



6. Ithomia rliene. 



5 . Exp. 2" 15 in. Allied to /. cassotis as to the distribu- 

 tion of the dark and diaphanous portions of the wings, and 

 belonging to the same group ; the lower radial of the secon- 

 daries makes a more acute angle with the median nervure ; and 

 the cell is much longer, leaving the lower radial extremely 

 short. 



Hab. Panama {liibbe).

7. Tithorea innthias. 



<S , exp. 3"6 in. ; 5 , 3*8 in. AUied to T. duenna ; but the 

 base of the primaries is black, and there is no black cross band 

 to the secondaries; the prothorax is black, whereas in T. duenna 

 it is rufous : also allied to T. tarracina^ but differing in the 

 absence of the yellow spots near the apex of the secondaries. 



Hab. Panama [M^Leannan)] Veragua {Arce) ; Costa Rica 

 {Rogers) ; Nicaragua, Chontales {Belt). 



Mus. nostr. 



We have long hesitated to differentiate this species ; but so 

 many examples have now come under our observation, all 

 agreeing accurately with one another, that we think there 

 can be no doubt that the race is a well-defined one, distinct 

 both from its northern relative, T. duenna^ and from its 

 southern, T. tarracina. 



BnASSOLIN^. 



8. Narope testacea. 



6 . Exp. 2'3 in. Above nearly uniform dull brick-red ;
