2. Hypolycsena Tmolus. Plate XXI. figs. 6 6, § 3. 



Hypolycasna Tmolus, Felder, Wien. Ent. Monats. vol. vi. p. 293, 1S62. 



In the Collection of "W. C. Hewitson, from Luzon and Lizard Island. 



I had thought that the insect from Luzon (figure 3 of the plate) described by Dr. Felder as 

 a new species might be only a female variety of H. Erylus, until I received the example at 

 figure 6, which I believe to be its male. The female does not differ from Erylus on the 

 underside, and has the transverse band continuous, or nearly so, where the wings meet, whilst 

 in figure 6 it is far apart.

Examples of this species differ greatly in size. A male from Mysol, from the Collection of 

 Mr. Wallace, measures only an inch and two-tenths across the wings, whilst another male 

 from Waigiou is an inch and seven-tenths. Some males are without the longitudinal ray of 

 white on the anterior wing.

 Myrina Thecloides, Felder, Wien. Ent. Monats. vol. iv. p. 395. 



In the Collection of W. C. Hewitson, from Singapore. 



On the underside this species scarcely differs from H. Amasa. I have not seen its female.
