 elevated at its end. Appendages much as in E. variegata, but the dilated portion is 

 more quadrate if viewed in profile ; the upper edge with fine denticulations.

It is evident that this species is closely allied to E. Aspasia, De 

 Selys, which is from the same island, and which is known from only 

 2 c? (^ Synopsis, p. 52, 4^^^ Additions, p. 28). One of these is said 

 to be adult, the other immature. Putting on one side certain differ- 

 ences in the yellow markings of the head, thorax and sides of the base 

 of the abdomen, and in the number of ante- and post-cubital nervules, 

 I note the following discrepancies in the coloration of the wings. In 

 the original adult ^ of Aspasia the tinting of the wings is said to pass 

 insensibly into blackish-brown at the tips, without, however, becoming 

 opaque, and this dark colour is prolonged up to the nodus in the an- 

 terior and somewhat less in the posterior. In the immature ^ there 

 is apparently no trace of the dark apical portion ; the anterior wings 

 have a dark shade along the costal margin ; in the posterior this shade 

 commences near the quadrilateral, and ends suddenly midway between 

 the nodus and the pterostigma. 



In the type IE. JBochi, the blackish apical portion is opaque (or 

 nearly so), limited internally in a sudden and straight manner (as in 

 the posterior wings of impar, only less extended). In the anterior 

 wings there is no trace of costal darkening, in the posterior there is a 

 dark line from the pterostigma nearly up to the nodus. Thus, unless 

 Aspasia prove a very variable insect, Bocki is either distinct, or forme 

 a strongly-marked local race. 



EuPH^A VAEiEGAXA, Eambur.— Many t^ , and a few $. The 

 colours are absolutely the same as those of typical examples from 

 Java, yet the posterior wings are appreciably narrower. Taking an 

 example from each island in which the length of the posterior wings 

 is 28 mm. in both, I find the breadth in that from Java is 9 mm., 

 whereas in that from Sumatra it is barely 8| mm. 



Ehinocypiia angusta, De Selys. — An amended description of 

 this, after mature examples, appears in the 4"^®^ Additions, p. 44 (1879). 

 I have 8 (^ and 2 $ before me. No two of the males agree precisely 

 in the form of the vitreous spots of the posterior wings. In all of 

 them there is a discrepancy in the length of the basal vitreous line 

 above the median sector. In the description it is said to commence
