 (Black, yellow, and blue.) 



The insect on the left of the illustration, on page 624, is a 

 very rare species, called Erycina Atahualpa. It was brought 

 from New Grenada, and the specimen is now in Mr. Hewitson's 

 collection. The upper wings are much pointed. Their colour is 

 black, and across them runs diagonally a single narrow streak of 

 crimson. Parallel with the outer edge is a row of blue spots. 

 The lower wings are lengthened at the tips into a short and 

 rather rounded tail, the two diverging from each other. Their 

 oround colour is black, and across them runs a band of crimson 

 which joins that of the upper pair when the wings are spread. 

 Parallel with and close to the outer edge is a band of dark blue, 

 and just within it is a similar band of paler blue. There is a 

 row of little white spots on the edge of the wing. 



The second species is a native of the Amazons district, and 

 is called Erycina Caljphurnia. The illustration represents the 

 male. The upper wings are brown, with a white band drawn 

 across the centre, and a blue band on the lower half of the outer 

 edge. The lower wings are elongated so as to form two diverg- 

 ing tails, and are beautifully and elaborately coloured. A while
