[Jjinuary, 



Dr. Fi'Ller iu this opinion, not being able to find females of the new 

 form amongst a long series which I examined, and so entered the form 

 provisionally in my collection as a variety under the name which he had 

 given it. The only points of difference from E. Ancea, besides the 

 shape of the tawny-orange belt, are the black colour of the two basal 

 lines on the under-surface of the hind-wings, and the central brown 

 line of the same wings being reduced to a series of lunules surmounting 

 the ocelli. 



Within the last month, the correctness of the decision of Dr. Felder 

 has received confirmation in quite an unexpected manner. A pair 

 of the doubtful form, taken in copula, has come to light. This pair 

 formed part of an interesting collection of insects made in Demerara, a 

 few years ago, by Bernard Piffard, Esq., who kindly brought them to 

 me, simply as likely to prove interesting on account of having been 

 taken in copula. The pair has proved interesting, for an examination 

 of the female has shown that, in all the minute points (colours and 

 shapes of streaks of the under-surface of the wings) which distinguish 

 the male U. Batesii from both sexes of E. Ancea, the female perfectly 

 accords with the male. I have compared it closely with about twenty 

 pairs of E. Ancea, and find that it differs in the same degree from all. 

 The shape of the tawny-orange belt, of course, cannot be compared, 

 as this is a decoration belonging to the males only of the two species. 

 The following is a description of the female : 



Epicalta Batesii, Eelder. 

 Lepidopterische Fragmente, p. 57, pi. 10, f. 3. <? . 

 ? . Shape and expanse of wings same as in the ? of Mp. Ancea. 

 Wings, above, brownish-black, darker towards the apex of fore-wings. 



Fore-wing crossed, a little beyond 

 the middle, by an opaque light blue 

 belt, broadest in the middle, and not 

 reaching the outer edge ; near the 

 apex is a small light blue spot. 

 Hind-wing with a small spot of light 

 blue at the apex. Beneath, both 

 wings light green ; fore-wing cell 

 with a spot and three transverse 

 streaks black ; blue belt as above, 

 but paler, especially towards the 

 costa, and margined on the inner 

 side with black. Hind- wing with 

 two black lines near the base and 

 crossed, at the middle and towards 

 the outer margin, by a reddisli-brown line, the row of minute spots 

 between these two lines sui'mounled each by a brown lunule.
