25. Catagramma titania. 

 c? . Exp. 2-25 in. Antennoi black ; palj)! black, anteriorly 

 white ; head black, with small white spots near tlie origin of 

 the antennas ; prothorax black ; thorax and wing-lappets 

 brown ; abdomen black : anterior wings crimson on the basal 

 portion, the inner margin, costa, and apical portion black 

 glossed with deep blue ; there are three reddish spots near the 

 apex of the wing : posterior wings black, glossed in the centre 

 Avith deep blue ; brownish hair-like scales cover the basal por- 

 tion ; the anal angle is sliglitlj prominent, and the cilia be- 

 tween the nervures are white : beneath, anterior wings as 

 above, but paler, and the black portions without the blue gloss; 

 a yellow band crosses the apical angle, cut near the outer 

 margin by a submarginal blue band, which follows the bend 

 of the same angle : the posterior wings have an irregular oval 

 yellow ring enclosing two pairs of blue spots divided by a 

 yellow line ; yellow lines extend along the costa, over the 

 subraedian nervure, and parallel with the inner margin between 

 these and the oval ring is another yellow line; crossing the wing 

 outside the ring, and following its emwe, is a broad blue line, 

 and between this and the outer margin a yellow band, which, 

 however, does not turn the anal angle. 



$ . Similar to the male, but larger, the anterior Avings less 

 pointed and rounder ; a yellow streak crosses the apical 

 angle. 



Hah. Borders of the forests of Guatemala, on both the 

 Atlantic and Pacific sides of the Cordillera. 



Ohs. This species is very closely allied to the Amazonian 

 species described by Mr. Hewitson as C. maimuma ; but I have 

 seen so very many specimens, none of which quite correspond 

 with South-American examples, but wliich agree most closely 

 with one another, that I am satisfied tlie two species can 

 always be distinguished. There is a wide gap between the 

 ranges of C. maimuma and C. titania ; the latter, though 

 abundant in Guatemala, and ranging, I believe, as fc\r south as 

 Nicaragua, has not yet been taken anywhere southwards of 

 this ])oint ; the former has not yet been met with beyond the 

 districts bordering the Upper Amazon and its affluents, and 

 even there seems to be a scarce species. The most noticeable 

 differences between the two are as follows : in C. titania the 

 crimson patch of the upper wings is more restricted, and the 

 dark parts glossed with blue, the anal angle of the posterior 

 wings is more j)roduced, and the patch of blue more widely 

 diftiised ; on the underside the yellow lines are constantly 

 narrower.
