middle of the wing, discocellular strongly angulated ; median 

 vein emitting its second and third branches from a very long 

 footstalk. Body similar to Dyplilebia. Type /. tricolor. 



33. Isorropus tricolor, sp. n. 



Wings bright orange, with broad black-brown outer borders, 

 widest upon the costal margin ; primaries witli a broad black- 

 brown central belt, both border and belt on these wings shot 

 with dark green: body carmine-red. Expanse of wings 

 1 inch 5 lines. 



Two examples of this species were sent home ; but one of 

 these is so much worn and broken as to be valueless ; the 

 type is in fairly good condition. 



34. Sommeria extensa, sp. n. (no. 15). 



Primaries chalky white ; five black dots at the base fol- 

 lowed by a short dark brown costal clash, two black dots in 

 the cell and two near the base of interno-median area ; a 

 zigzag central olive-brown stripe from costa to inner margin, 

 an oblique series of fusiform olive-brown spots from the end 

 of the cell to the costa, and an indistinct irregularly angulated 

 discal series from apex to external angle : secondaries cream- 

 coloured : thorax white, black-spotted ; abdomen ochreous, 

 with dorsal and lateral series of black spots ; antennas black. 

 Primaries below paler than above ; costal borders testaceous ; 

 black dots obsolete, brown markings indistinct : secondaries 

 sordid white, with testaceous costal border and veins ; body 

 below white, pectus black-spotted. Expanse of wings 1 inch 

 10 lines. 



One example only ; it is most nearly allied to 8. privata, 

 but is considerably larger, with much longer wings.

I cannot believe that this is the male of the following, the 

 sexes of all the other species being extremely similar, and the 

 supposed female being of the same form and coloration as the 

 species of Damalis. 



36. Damalis insularis. 



Aganais insularis, Boisduval, Faun. Madag. p. 97, pi. xv. fig. 2 (1833). 

 Nearly allied to D. egens.
