ERYCINID.E. 



Genus XXXI. CREMNA. 



Cremna E. Doubleday, List Lep. B. M. 

 Hamanumida p. nubner. 



Body small, moderately slender; wings large, dark-coloured, marked vnth numerous pale spots or strigaj. 

 Head small, with a strong tuft on the crown, and also on the face. 



Eyes naked. 



Antennce about lialf the length of the fore wings ; joints distinct, ringed Avith white ; club rather short, gradually 

 formed, moderately robust, incurved at the tip. 



Labial Palpi porrected obliquely, slender, rather elongated, the tip about level with half the height of the eye, 

 and extending rather beyond the hairs of the face ; second joint long, scaly, scarcely hairy beneath ; terminal 

 joint very short, slender, more ovate in the female. 

 Thorax moderately robust, spotted with white. 



Fore Wings large, nearly obovate. Costal margin much arched ; apical angle more or less obtuse. Apical 

 margin more or less dilated, alike in both sexes. Postcostal vein with four branches ; the first and second 

 arising before the anterior extremity of the discoidal cell ; third branch about one third of the length between 

 the cell and the tip of the wing ; fourth branch near the tip. Upper disco-cellular vein very short, very 

 oblique : middle and lower ones much curved, the extremity of the latter directed toward the apical margin, and 

 uniting with the third branch of the median vein at a moderate distance beyond its origin. 



Hitid Wings broad, entire. Costal vein reaching to about half the length of the costa. Postcostal branching at 

 a considerable distance beyond its base. Upper disco-cellular vein arising almost simultaneously with the 

 brancli ; very oblique: lower one much longer tlian the upper and arched, uniting with tlie third branch of 

 the median vein at a moderate distance from its base. 



Fore Legs of the male vei-y short, thick, and moderately hairy. Fore Legs of the female about three times the 

 length of those of the male, thick, scaly. Tarsus armed beneath with strong spines at the tips of the 

 intermediate joints. 



Four Hind Legs short, thick, and scaly. Femora curved. Tibiffi destitute of spines beneath. Tarsi thick. 

 Ungues and appendages minute. 



The dark-coloured whigs of the species of this genus covered with numerous pale spots or streaks, joined to their slightly waved 

 hind margin, give them a certain resemblance to the species of Calydna ; from which, however, they are at once distinct in their four- 

 branched postcostal vein of the fore wings, and in the curved base of the j)ostcostal vein of the Ixind wings. The characters detailed 

 above are drawn from C. Ceneus, the males of whicli have the sj)ottings of a [)ale blue, whilst they are pure white in the female. The 

 apical margin of the fore wings in both sexes of this species is singularly dilated, the apical angle itself being slightly produced. In 

 C Actoris and Thasus the wings arc of the ordinary form ; the spots of the former being replaced in the latter by transverse slender 

 fasciaj.
