CHINESE DREPANINAE 55 



Betalbara leucosticta (Hampson) comb. n. 

 (PI. 2, fig. 314 ; Text-figs. 85-88) 



Drepana leucosticta Hampson, 1895 : 287. 



Albara leucosticta (Hampson) Warren, 1922 : 469. [Fig. inaccurate, but useful guide.] 



Albara leucosticta (Hampson) ; Gaede, 1931 : 32. 



Probably quite closely related to prunicolor but distinguished by the colour- 

 pattern of both sexes (PI. 2, fig. 314), the bipectinate antennae of the female, the 

 shape of the male aedeagus and eighth abdominal tergite and sternite and by the 

 lack of a signum in the female genitalia. 



Wing. $ 11 -5-14-0 mm. (8) ; $ 15-0-16-0 mm. (3). 



Distribution. Sikkim, N.E. India, China and Malaya. 



Material examined. Type. I select as LECTOTYPE a^ syntype in the BM(NH) 

 labelled : Sikkim, 8.7.91, G. C. Dudgeon, 94-52 ; Drepana leucosticta Hampsn. 

 type <$ ; Drepanidae genitalia slide No. 1600. 



Other material. BM(NH). India : 7 <$, 3 $, Assam, Khasis, xi.1894, x.1895, 

 1906. Museum Koenig, Bonn. China : 1 <$, [Kwangtung], Canton. Two males 

 from Malaya in the BM(NH) may prove to represent a new subspecies. 



Betalbara flavilinea (Leech) comb. n. 

 (PI. 2, fig. 313 ; Text-figs. 89-96) 

 Albara flavilinea Leech, 1890 : 113. 



Distinguished from the closely related prunicolor by the dentate (not sharply 

 angled) postmedial fascia on the fore wing and by the fact that R\ arises from the 

 distal end of the cell. Separated from both prunicolor and rectilinea by the genitalia, 

 in particular by the presence of saccular processes in the male and the absence of a 

 signum in the female. 



There are two subspecies, both at present known only from China. There is, 

 however, a single male, without an abdomen, from Formosa, in the BM(NH) which 

 will probably prove to represent this species. 



Betalbara flavilinea flavilinea (Leech) 

 (PI. 2, fig. 313 ; Text-figs. 89-91) 



Drepana flavilinea (Leech); Strand, 191 1 : 201 [Fig.] 

 Drepana flavilinea (Leech) ; Gaede, 1931 : 26. 

 Albara prunicolor flavilinea (Leech) Gaede, 1931 : 33. 

 Nordstroemia prunicolor flavilinea (Leech) Bryk, 1943 : 14. 



In the fore wing of the illustration given by Strand (191 1) the postmedial fascia 

 should be only slightly arcuate posteriorly and more acutely reflexed costad.
