and the variation is almost an epitome of the changes 

 whereby the small triangular apical field of such genera as 

 Edohia and Thegano'ptcryx has become modified into the 

 large parabolic apical area of the genus Anapleda. 



Anapleda cJvnjsojjtera, n. sp. (Plate XVI, fig. 7.) 



$ . Very convex. Rufous. Antennaj testaceous ; third joint of 

 maxillary palpi black ; pronotum with lateral margins rufo-testace- 

 ous ; abdomen and cerci castaneons, the apical joint of the latter 

 yellow. Marginal field of tegmina nearly half the total breadth, 

 thirteen parallel costal veins ; the tegmina strongly overlap, veins of 

 discoidal field of left tegmen obsolete, strongly marked in that part 

 of the right tegmen which is covered by the left, the ulnar vein 

 sends six branches to the sutural margin, anal vein strongly marked, 

 axillary veins obsolete. Wings with the apical area and marginal 

 field golden-yellow, fourteen costal veins, their ends slightly swollen, 

 radial vein straight, medio-discal field crossed by eight transverse 

 venulte, ulnar vein simple, first axillary vein qnadri-ramose, apical 

 area two-fifths of total wing-length, its basal margin obtusely angled. 

 Supra-anal lamina transverse, sub-genital lamina large, its posterior 

 border shortly cleft and compressed laterally in the centre 

 simulating a valvular appearance. 



Total length 7 '5 mm. ; length of tegmina 6 mm. 



Amazons (R. W. Bates). One example (Oxford 

 Museum). 



This somewhat remarkable species is most nearly allied 

 to A. fiabdlata, Sss. and Zhnt. The unique example was 

 labelled in Walker's handwriting " Biatia sp." ; the genus 

 Biatia (type B. jycdlicomis, Wlk.) is too close to Anapleda 

 to be entitled to separate rank. 



Genus Anaplectoidea, uov. 



Differs from Anapleda, Burm., in the branching of the ulnar vein 

 of the wing. Elliptical, smooth, shining ; vertex of head reaching 

 anterior border of pronotum ; eyes less remote than the insertions 

 of the antennse ; pronotum transversely elliptical. Tegmina with 

 marginal field very broad occupying almost half the total breadth. 

 Ulnar vein multi-ramose, anal vein deeply impressed, axillary veins 

 obsolete. "Wings with numerous costal veins, medio-discal field 

 crossed by numerous transverse venuL'e, ulnar vein multi-ramose, 

 the veins being given off towards the dividing vein, apical area small.
