624 On Butter/lies from New Guinea mid Tenimher. 



tooth at middle ; extremity a little more rounded, its dorsal 

 angle right, not acute; hook of harpes not so long ^ as in 

 zoraide^ more inwardly curved. Penis similar to that o£ 

 T. I. zoraide^ but not so acutely truncate at extremity, the 

 truncation not sinuous, but straight. 



Expanse. — 35 mm.

This race differs from the allied zoraide and drona, in 

 addition to the characters given above, by the shape of the 

 wings, which are rounder, especially the posterior pair, and 

 by the black border of the hind wing narrowing less abruptly, 

 but remaining of nearly equal breadth up to the tornus. On 

 account of the genitalia, however, this form seems to con- 

 stitute only a local race. 



The discovery of T. lihythea in the Tenimber group is very

interesting, three species of the genus Terias being already 

 known from there — T. apatosa, Hulst., T, hecabe hrevicostulis, 

 Butl., and T. lihythea dioyiysiay Hulsfc. It would not be 

 surprising if still further species, such as T. Candida^ Or., and 

 some Australian ones, should be found on these islands, on 

 account of their known relationship with Australia and New 

 Guinea on the one hand, and with the Timor group and the 

 Lesser Sunda Islands on the other.

Above. — Much darker, almost completely black ; discal 

 pale area entirely brownish yellow, not lighter distally, not so 

 large as in catana and in iapudia, Fruhst., not extending into 

 cell nor above half interspace 3, remaining some mm. from 

 outer margin, just passing vein 1, not reaching base of wing, 

 its costal edge rounded, sharply limited above, diffusely
