Plate X. 



1. Catocala thomsoni sp. nov. (pi. XXII, fig. 1). 



$ ? , 56—63 mm. 



Head, palpus, antenna and thorax nearly as in C. deuteronympha 

 Stgr. (Stett. Ent. Zeit., 1861, p. 290 [E. Siberia]), but the third 

 segment of palpus appreciably shorter than in $ and ? of deutero- 

 nympha in coll. Brit. Mus. ; apparently also a trifle thicker and blunter 

 at the tip in thomsoni ; the patagia with a broad dark band at the 

 middle, but with scarcely any trace of dark shading at the tips. 

 Pectus, legs and abdomen much as in deuteronympha. 



Fore wing appreciably shorter and broader than in deuteronympha. 

 Differs from that species also in the more prolonged darkening of 

 B 2 beyond the reniform, in the absence of dark shading on the pale 

 sinus of postmedial line behind reniform and in the dark shading 

 distally to the postmedial and subterminal lines being weaker and 

 more ochraceous in tone than in deuteronympha. 



On the hind wing thomsoni differs from deuteronympha in having 

 the dark hair in the fold much slighter (sometimes hardly present), 

 the terminal black band slightly narrower at the radials and the 

 medial band much narrower. 



The underside of the fore wing in thomsoni has the antemedial 

 half-band a little straighter and less oblique than in deuteronympha 

 and the terminal band usually ending just behind M 2 in the 3 . 

 The hind wing is more uniform yellow in thomsoni, except for some 

 deeper golden scaling on proximal half of wing from middle of cell 

 to middle of fold ; the medial band narrower than in deuteronympha, 

 obsolescent at costa ; the cell-spot reduced to a point ; terminal dark 

 band very slight, leaving a distinct yellow band at termen with only 

 very slight dark irroration.
