CHINESE DREPANINAE 17 



Albara reversaria Walker 



(PI. i, figs. 296, 297 ; Text-figs. 1-7) 



' Albaria ' reversaria Walker, 1886 : 1567. 



Two subspecies are known : the nominate subspecies (Sumatra), and opalescens 

 Warren (India, Formosa, China). Two males and eleven females in the BM(NH), 

 from Malaya, differ from the Sumatran material in minor genitalic characters and 

 may prove to represent a new subspecies. 



Albara reversaria reversaria Walker 

 (Text-figs. 1-4) 

 Albara reversaria Walker ; Gaede, 1931 : 33. 



Readily distinguished from opalescens Warren by the <$ genitalia (Text-figs. 1-3), 

 particularly by the shape of the anellus, basal valve processes, medial gnathus 

 process, socii and uncus. 



Measurements. <$ 160 mm. (1) ; $ 15-0-18-5 mm. (8). 



Material examined. Holotype $, Sumatra ; in the Hope Department Museum, 

 Oxford. An examination of the genitalia slide made from the abdomen found 

 attached to the type (Drepanidae slide No. 263) has shown that this is not the 

 original abdomen. However the BM(NH) possesses a male and female from 

 Sumatra, the abdomens of which had not been glued on and are doubtless genuine. 



Other material. BM(NH). Sumatra : 1 <$, Barisan Range, Western slopes, 

 2500 ft., x-xi.1961 (Pratt) ; 1 $, Lebong Tandai, 6.xii.i92i (Brooks).

Albara horishana Matsumura, 1921 : 948. syn. n. 



Apparently indistinguishable externally from the nominate subspecies, but with 

 distinctive male genitalia. The female is unknown. 



Wing, <J 15-0-19-5 mm. (9). 



I have not seen the type of horishana Matsumura, but this has been kindly 

 examined for me in Japan by Dr. H. Inoue.
