Cleora cancer sp. n. 



(Text-figs. 22-24 I PI- 3> fig s - 188-191 ; Map 1) 



o*. Vestiture white, densely irrorate with vinaceous buff and fuscous. Fore wing white, 

 irrorate with vinaceous buff and fuscous, densely along costa ; apex suffused with light drab ; 

 some ochraceous buff irroration in preterminal area of discal fold and in sub-basal area ; ante- 

 and postmedial fasciae slender and fuscous black, the latter right-angled on vein Ma. Hind 

 wing white, sparsely irrorate with vinaceous buff and fuscous ; some ochraceous buff irroration 

 in preterminal area of discal fold ; medial fascia, from discal spot to anal margin, and slender 

 postmedial fascia, the latter right-angled in discal fold, fuscous black. Underside of wings 

 white patterned with fuscous black. 



In two male and three female examples the medial fascia on each wing is strongly developed 

 and from it a fuscous black horizontal streak extends along discal fold to termen (PI. 3, figs. 188, 

 189). 



cj. Genitalia (Text-figs. 22, 23). Arm of sacculus extending from one-half to five-sixths 

 ventral margin of valve, apex bifurcate and claw-like, partially covered with a setose, membra- 

 nous fold from the ventral margin of the valve ; process near base of claw-like structure broad 

 and dentate on inner margin ; aedeagus broadened apicad ; vesica with two tapered cornuti, 

 each three-sevenths as long as and a longitudinal, scobinate band one-third as long as aedeagus. 



$. Similar to male externally (PI. 3, figs. 190, 191). 



$. Genitalia (Text-fig. 24). Lamella postvaginalis strongly sclerotized and shaped as 

 illustrated ; colliculum with a short lip projecting ventrad ; anterior fifth of bursa copulatrix 

 membranous, remainder ribbed and sclerotized. 



Measurements. o* 44-47 mm. ; $ 45-49 mm. 



The structure of the male genitalia shows a close affinity with betularia ; a 

 tendency to a comparable variation in wing pattern is also apparent. Externally 

 the marked right-angling of the postmedial fascia and structurally the shape of the 

 sacculus and ornamentation of the vesica in the male and the lip on the colliculum 

 in the female are diagnostic.

Cleora tamsi sp. n. 



(Text-figs. 25-27 ; PL 4, figs. 192-196 ; Map 9) 



o*. Head cinnamon brown ; patagia fuscous with a few tilleul buff scales ; abdominal crest 

 tilleul buff ; remainder of vestiture tilleul buff, irrorate with fuscous. Fore wing tilleul buff, 

 irrorate with ochraceous buff, drab and fuscous ; sub-basal fascia broad and ill-defined ; ante- 

 and postmedial fasciae fuscous black, sharply defined ; horizontal fuscous black streak distad of 

 postmedial fascia between veins Mi and M3 ; broad fascia of ochraceous buff and drab distad of 

 and parallel with postmedial fascia ; discal spot white, outlined with fuscous black. Hind 

 wing similar, but antemedial fascia wanting and medial fascia present (PL 4, fig. 192). Under- 

 side of both wings white, patterned as illustrated with bister ; discal spots fuscous black 

 (PL 4, fig. 193).
