440 Some apparently new Noctuidae from Sumatra, etc. 



between the distal dark bar of the reniform and the proximal postmedial 

 line. In champa the distal postmedial line has usually a large almost 

 triangular spot at its origin on costa, which is slighter and more 

 irregular in androdes. Varies much in the strength of the black 

 markings, but the medial line is almost always the strongest. 



In the <? of androdes the apex of hind wing is only very slightly 

 irrorated with brown and is strongly iridescent, with greenish, bluish, 

 pinkish or purplish reflections, according to the position from which 

 it is viewed.

14. Dipthera tamsi sp. nov. (pi. XIII, fig. 12). 

 $ , 44 — 47 mm., ? , 58 mm. 



Head, thorax, abdomen and legs much as in D. champa Moore. 



Fore wing silvery white, slightly tinged with pinkish or cream- 

 colour ; markings much as in champa but broader, much more heavily 

 blackened, and differing in the following points : Antemedial line 

 thickened in fold ; orbicular black ring averaging rather larger and 

 more elongate than in champa; the horizontal black streaks behind 

 orbicular rather short and broad ; space between reniform and inner 

 postmedial line filled in with black, the line scarcely dentate ; outer 

 postmedial from a heavy, triangular patch at costa, proximally curved 

 but not dentate, distally with thicker teeth than in champa ; subterminal 

 with strong black teeth fitting into the interspaces of the outer post- 

 medial ; terminal black spots on the veins lozenge-shaped. Hind wing 

 above and under surface much as in champa.

It is just possible that tamsi is a high elevation race of champa 

 Moore, with which species it seems to agree in structure as well as in 

 the main scheme of pattern ; but it is a very distinct and (apparently) 

 a very constant form, and all Dipthera species run so near to each 

 other that it seems wiser for the present to treat each distinct form 

 as a good species. 



15. Dipthera leucotaenia sp. nov. (pi. XIII, fig. 13).

Coloration much as in D. champa Moore, from which species 

 leucotaenia differs in the following points,
