Ovipositor retractile, terminating with a slightly 

 emarginate plate. Ostium narrow; ductus bursas constructed 

 near the ostium. Signa two pilleate, one broader than the 

 others: acobinate. 



Genus 3. type 



Somewhat closely allied to the preceding genera, but the 

 long uncus and semifloricomous ovipositor denote either a 

 singular divergence or a separate genus. 



tritnaculana, Don. 1 — 1 



J. W. M. 



Valva curved, deeply indent at its junction with the sacculus. 

 Uncus long, slender, double pointed; socii drooping. 

 /Edoeagus short; cornuti 15 long, broad, deciduous. 



Ostium semifloricomous, set with long clavate spatulate 

 spines, ending in a curved sharp point. Ostium simple, 

 lined with minute spines inside; ductus bursa? thickened. 

 Signa two, long, scobinate. 



Genus 4. Astatia, H b type solandriana, Stph . 



This genus may be distinguished by the long uncus doubly 

 pointed at the tip, the large broad socii and the rather 

 pronounced shape of the valvae and sacculus, the latter 

 bearing strong spines. The female has the two pilleate 

 signa that seem to accompany this rounded form of valva. 



The species run so closely together that they are only 

 separable by comparison. 



The cornuti vary in shape, some are figured. 



Astatia ophthalmicana, Hb. 3—2 



Valva curved, broader towards the apex; sacculus angulated, 

 a small wide angular indent at the junction. Uncus long, 

 strong, bipointed; socii large, angular. iEdoeagus wide, 

 pointed; cornuti long, about 22, deciduous. 



Ovipositor wide, flattened; ostium narrow, simple; 

 signa pilleate, wide, scobinate.
