Three new Catocalinae 453 



North China: Tientsin, June, 1922 (F. M. Thomson), six 3 3 , 

 one ? . 



Nearest to C. deuteronympha, of which it might well be a local race 

 were it not for the structural difference in palpus and shape of fore 

 wing. 



2. Catocala jansseni sp. nov. (pi. XXII, fig. 2). 

 ? , 58 mm. 



Differs from C. triphaenoides Ob. (" Et. Ent.," vi, p. 21, pi. viii, f. 5 

 [1881] [North China]), in the following points : in jansseni the 

 antemedial line is (apparently) more oblique, with proximal dark 

 suffusion (broad at costa narrowing to hind margin) , bidentate behind M ; 

 postmedial line much more dentate than in triphaenoides, with long black 

 teeth behind R 1 and R 2 and the proximal end of sinus bidentate ; sub- 

 terminal line sharply defined and strongly dentate ; a patch of dark 

 suffusion from about two -fifths to four-fifths costa, extending to behind 

 reniform ; termen with dark streaks behind SC 5 , R 1 , and R 2 . 



Hind wing with slight black mark on origin of SC & and R 1 ; the 

 terminal spots before and behind SM 2 large, coalescent, forming a 

 V-shaped mark. 



Fore wing beneath with large black patch in base of fold, postmedial 

 black band from origin of R 1 to hind margin near tornus, almost con- 

 tinuous with a broad irregular black costal patch ; the terminal band 

 extending to tornus and without the pale shade at termen. 



Hind wing with bidentate black bar at middle of costa ; the terminal 

 band slight to M 2 ; a slight black streak on SM 2 . 



Central China: Ichang, June, 1922 (C. T. Bowring), ? —allotype 

 only. 



As both fore and hind tibia in this specimen are unfortunately 

 wanting, it is impossible to say with certainty whether this species is 

 a Catocala or an Ephesia. It appears nearest to Ephesia triphaenoides 

 Ob., and E. vallantini Ob. (" Et. Ent.," xix, p. 36, pi. vi, fig. 53 [1894] 

 [Algeria]), both of which species lack the medial black band on the hind 

 wing. As, however, there seems a doubt as to the validity of Ephesia, 

 I prefer to employ the old, universally accepted generic name Catocala. 



At the suggestion of Mr. Bowring I dedicate this species to Pere 

 Janssen, who assisted him materially in his collecting at Ichang,
