iorcipate. 1, therefore, amend this part of the detinitiou 

 as follows: — Superior appendages of male not forcipate, but 

 tkick and only slightly curved ; inferior forcipate and pro- 

 jecting well beyond them. 



cf . Appendages of .4. fieldi: superior 0-8 mm., pale straw- 

 colour, very thick, slightly curved, tips broad and rounded, 

 an inner projecting tubercle about two-thirds from the base. 

 Inferior 1-3 mm., slender at tips, but with broad thick bases; 

 forcipate, tips clubbed and rounded ; pale straw-colour. Seen 

 in profile, the superior appendages are very thick, depressed ; 

 the inferior very stout for their first three-fifths, then slender 

 and somewhat upcurved.

 ai:d one damaged female taken by Mr. J. F. Field, in April,

Neosticta, n.g. (Plate xlvii., fig. 6).

 two antenodals, but closer to the first than to the second. 

 Wings petioled to just beyond the level of the arculus. In-

 several cells beyond the level of the nodus. Median sector

 tinguished from both by the f(jrm of the male appendages, 

 and by the much greater length of the superior sector of the 

 triangle.
