Indians will not easily be found in Chiriqui to carry your luggage, 

 everytliing has to be carried on pack horses or mules, unless you are 

 making the three or four days' journey across to the Chiriqui lagoon 

 on the Atlantic coast from David or Caldera, to make this trip you 

 may, perhaps, find carriers ; the path or road is seldom traversed 

 except by natives, and is quite impracticable for horses or cattle. 



I will now conclude my remarks on collecting in Central America, 

 and hope they may be of use to future travellers.

TWO NEW BUTTERFLIES ALLIED TO APHN^US NATALENSIS. 



BY ARTHUR G. BUTLER, F.L.S., F.Z.S., &c. 



The two following species bear so strong a resemblance upon the 

 upper surface to Aphnceus natalensis* that, when we received them, I 

 unhesitatingly placed them in the cabinet with our series of that 

 species ; indeed, the chief difference on the upper surface is iu the 

 greater width and more ochreous tint of the V-shaped band on the 

 primaries : the differences on the under-surface are, however, more 

 marked, and are as follows : — 



APHlf^US TTSTASSiE, S^J. 11. 

 Under-surface creamy sulphur-yellow, purer m tint than in A. nataletisis, the 

 silver markings on the bands more continuous, almost touching, and iu parts 

 quite toiicliing the margins of the bands, which are considerably thicker, and, for 

 the most part black, though varied here and there with dull dark red ; primaries 

 with the third (oblique) band considerably more oblique than in A. natalensis, the 

 costal spot further beyond it, the abbreviated discal band slightly irregular, the sub- 

 apical costal spot absent, the sub -marginal lines slightly undulated and nearer 

 together ; secondaries with most of the spots towards the base filled in with dark 

 red, the oblique post-median band slightly curved and well separated from the ab- 

 breviated discal band, which is narrower ; instead of the two sub-marginal stripes, 

 there is a single tapering, bright safPron-yellow stripe from the elbow of the post- 

 median band (where it unites with the band from the abdominal margin) to near 

 the apex, a slender, abbreviated, sub-apical black stria between it and the margin. 



Expanse of wings, 35 mm. 

 Lake Nyassa. 



• I may note here that the species figured by Hewitson in his " Illustrations," is not the true 

 A. natalensis, or, indeed, at all nearly allied to it.
