lower discoeellular covered by a cuneiform black spot. Ex- 

 panse of wings 1 inch. 



The type of Walker's G. pyloalis is in such poor condition, 

 being much rubbed and destitute of fringe to the wings, that 

 it is no wonder that I did not at first recognize its specific 

 identity with the fresh and nearly perfect example obtained 

 by Mr. Jonas. 



116. Margaronia imtsitata, n. sp. (no. 983). 



Snow-white, sericeous : wings crossed by a sinuous discal 

 greyish-brown line ; three black-edged pale copper-brown 

 discoidal spots confluent with the costal border, which is also 

 pale copper-brown ; a fourth spot below the cell : secondaries 

 with a black-edged small spot in the cell, and a larger one. 

 closing the cell : frons yellow ; palpi black ; shoulders red- 

 brown. Under surface with the markings much less distinct, 

 partly obsolete. Expanse of wings 11 lines. 



Nearest in appearance to Cirrhochrista brizoalis y but very 

 distinct in form. 



Botididae. 



117. Mecyna prunipennis, n. sp. (no. 1024). 



Primaries above reddish brown, tinted with plum-colour ; a 

 greyish spot at the end of the cell : secondaries sordid ochre- 

 ous, with a grey external border : thorax plum-coloured ; ab- 

 domen testaceous. Under surface ochreous ; wings with rose- 

 coloured tips ; primaries with an oblique brown dash at the 

 end of the cell, fringe brown ; legs whitish, the femora clouded 

 with rose-colour. Expanse of wings 1 inch 4 lines. 



Phycidae. 

 Paralipsa, n. gen. 



Aspect of Achroea) allied to Alipsa, from which it scarcely 

 differs in the neuration of the secondaries ; but the structure 

 of the primaries is altogether distinct, that of Alipsa being 

 very simple, the costal vein simple, terminating at about 

 second third of costa, the subcostal four-branched, the cell 

 very long, the discocellulars forming a transverse zigzag line, 

 from the uppermost angle of which the upper radial is emitted, 

 and from the lowest the third median and lower radial are 

 emitted upon a long footstalk, the first and second median 

 being emitted near together from the inferior extremity of the 

 cell, and being distinctly curved, the median vein is slightly 

 inarched, as well as the vein-like fold immediately below it, 

 and the submedian is long. In Paralipsa the base of the
