CHINESE DREPANINAE 117 



(1959, 1962) together with the paler unspotted f. palleolus Motschulsky (= ab. 

 simplificaria Strand, 191 1 : 202). 



The unspotted form of this subspecies is easily distinguished from the nominate 

 subspecies by the colour-pattern, but the male and female genitalia provide the 

 only significant diagnostic characters in the dark-spotted form. 



Distribution. Japan (see Inoue, 1956). 



Type. According to investigations made for me by Dr. K. M. Efron and Dr. A. S. 

 Danislevskyi in the U.S.S.R., all the Lepidoptera from the Motschulsky collection 

 have been lost. There seems little doubt, however, from the original description 

 that Nagano (1917) and Inoue (1959) have correctly identified this subspecies. 



Callidrepana ovata sp. n. 



(PI. 12, fig. 369 ; Text-figs. 228-231) 



d. Front of head dark reddish brown ; vertex, palp and bipectinate antenna dull yellowish 

 orange ; collar yellowish white. 



Thorax buff or yellowish white. Colour-pattern of upper surface of wings as in PI. 12, 

 fig. 369 ; colours similar to the pale form of C. patrana palleolus but usually paler ; scattering 

 of brilliantly lustrous scales present along veins proximal to postmedial fascia, along distal 

 edge of postmedial fascia and in streak in basal half of costal area. In fore wing R\ arises 

 from near distal end of cell, Ro from near distal end of areole ; Rs and Afj from a point or on 

 short stalk. Sc + R\ approximates to Rs for short distance distal to end of cell in hind wing. 

 Under surface of both wings pale yellowish buff, but fore wing more brownish basally ; fore 

 wing usually with trace of reddish brown postmedial fascia anteriorly, corresponding in position 

 to proximal part of this fascia on upper surface ; hind wing usually with trace of reddish 

 brown postmedial fascia, corresponding in position to distal part of this fascia on upperside. 

 Legs buff, but with outer surface of prothoracic tibia and tarsus brownish buff. 



Abdomen similar in colour to adjacent surface of hind wing. 



o" genitalia as in Text-figs. 228, 230, 231. 



$. As for male but with shorter antennal pectinations. 



Wing. 6* 15-5-19-0 mm. (45) ; 9 17-5-22-0 mm. (15). 



The cell-spot on the fore wing in most specimens of this species is less elongate 

 than that in the closely allied patrana and the fore wing is slightly more strongly 

 falcate. The male and female genitalia also distinguish ovata from patrana : in the 

 male the aedeagus is more slender apically and the socii less strongly arcuate 

 apically, while in the female the signum is over twice as long as in patrana. 



There is some individual variation in the postmedial fascia of the upper surface 

 of the wings, which in a few males and one female is much broader than in the 

 illustrated specimen, as in patrana palleolus (q.v.). 



Distribution. The sympatry which exists between this species and patrana at 

 Kwanhsien (Szechwan province) indicates that they are probably specifically 

 distinct. The distribution and morphological similarity between ovata and patrana 

 suggest a superspecific relationship (Artenkreis). Known from the following 

 Chinese provinces : Shensi, Hupeh and Szechwan.
