398 Mr. A. G. Butler on new Genera 



ptcrygodcs, and a spot on mctathorax sulphur-yellow ; abdo- 

 men oran_i2;e, baiuled with black ; antennae blaek ; priinaricvS 

 below with the internal area greyish with bronzy reflections ; 

 secondaries with the subcostal area of the ground-colour cream- 

 coloured ; otherwise as above : body below orange, varied 

 with black. 



Ex])anse of wings 2 inches 3 lines. 



Jlab. llakodadi {Whitclfj). Type, B.M. 



This is probably an imitation of Eusevu'a ; its resemblance to 

 E. viUicoide^ can scarcely be accidental (in structure it more 

 nearly agrees with Ali/jn'a). The JI)/pei-con>j>a longij^ennis of 

 Walker is clearly an imitation of Eusemia irenea. 



Family ArctiidaB (Zygasnoid type). 



Genus Acridura, n. gen. 



In general ap])earance most like the Zygxniid genus Echo- 

 neura. Wings narrow, hyaline, with veins black, margins 

 opaque ; primaries with four subcostal branches, the tirst 

 emitted just before the endof the cell, the second and fourth from 

 the end running close together at their origins, the third 

 emitted from the second near its origin and running parallel to 

 and above it ; diseocellulars transverse, the upper one reduced 

 to a mere point ; lower radial and second ami third median 

 branches emitted together at lower extremity of cell ; secon- 

 daries with the cell short, its upper extremity i)rojecting ; 

 subcostal with two branches, emitted from a footstalk beyond 

 the end of cell, diseocellulars forming a deep sinus, the upper 

 considerably shorter than the lower; lower radial and median 

 branches emitted together from the lower extremity of the 

 cell ; thorax broad ; head small ; palpi short ; antenna3 more or 

 less filiform ; abdomen slender, of the male with long com- 

 pressed clas])S. Type A.gryllina^ n. sp. 



6. Acridura gryllina J n. sp. 



(^ . AVings hyaline white, with rosy reflections ; veins, 

 borders, and apex dark brown ; base of costa steel-blue ; an 

 orange dot at the base ; body orange, with the anal segments 

 of abdomen and clasj)s steel-blue ; head black ; body below 

 black, with purplish, steel-blue, and greenish reflections; base 

 of abdomen with a white spot ; tips of tarsi white. 



Expanse of wings 1 inch 4 lines. 



Hah. Esj)iritu Hanto {Hiytjins). Type, B.M. 



This remarkable species is, I believe, an aberrant Aictiid.
