40. Rhodogastria rufitarsus, sp. nov. 



<J. Similar to caudipennis Walk., but distinguLshed by the different shape 

 of hindwing and the broader forewing. 



Antennae black, basal one-fifth crimson, not merely the basal joint ; fore- 

 tarsi entu'ely crimson, not merely the last joint ; head greyish white, not jjale 

 mouse-grey ; black spot on vertex much larger than one on frons, not equal 

 size ; thorax as in caiidipennis but paler ; abdomen brownish velvety putty 

 colour, not cream yellow ; whole of two last segments bright rosy carmine. 



Forewing much whiter, light patch beyond discocellulars hardly different 



from basal three-quarters of wing. ^Hindwing much larger than in caudi- 



pennis, the tornus hardly produced at all, and the termen barely excised ; the 

 apex pointed, not rounded, tufts in anal fold less voluminous ; whole wing cream. 

 less white. $ darker grey than caudipennis and hindwing presents some 

 differences in shape. 



Length of forewing : rufitarsus : (J 25 mm. Breadth of forewing, <? 15 mm. 

 ,, ., ,, caudipennis 23 mm. ,, ,, ,, o 11 mm. 



,, ,, ,, rufitarsus ? 29 mm. Expanse : <J 58 mm., $ 66 mm. 



Habitat. Rook Island. August 1913 (A. S. Meek), 1 rj, 3 ?? ; New Britain 

 (C. Wahnes), 1 ?. 



41. Rhodogastria curta, sp. nov. 

 (J. Differs from arthus-hertrand Guen. by the almost complete absence of 

 black spots on the thorax, by the more grey less brown colour of the forewings, 

 and by the extremely short rounded apex and termen of the forewings. 

 Length of fore^^ing : curtus 30 mm. 



., ,. ,, o arthiis-hertrand 35 mm. 

 ExiDanse : curtus 70 mm., arthus-hertrand 80 mm. 

 Habitat. Rook Island. July 1913 (A. S. Meek), 1 3. 



42. Rhodogastria simillima, sp. nov. 



(J?. Very closely allied to crokeri papuana Rothsch., but distinguished by 

 the front of the whole fore-tarsus and the distal half of the fore-tibia being 

 crimson, not merely the first tibial joint ; in the hmdwing being almost entirely 

 cream-white, not smoky grey ; and in the antennae being crimson for three 

 millimetres beyond basal joint. It is also smaller. 



Length of forewing : cJ simillima 27 mm., $ 31 mm. 

 ,, ,, ,, S c. papuana 33 mm., $ 35 mm. 



Expanse : S simillima 62 mm., ? 70 mm. 

 ,, o c. papuana 76 mm., ? 80 mm. 



Habitat. Rook Island, July 1913 (A. S. Meek), 1 S, 5 $?. 



43. Rhodogastria erythropus, sp. nov. 



(J. Differs from astreas Drury ui the entirely crimson forelegs faintly tinged 

 with brown on basal one-thud of tibia ; in the crimson base and tip of the 

 antennae, in the dark-grey head, thorax, and forewings, not brownish mouse-grey 

 as in astreas ; in the brilliant carmine-scarlet abdomen, not orange-salmon ; and in 

 the salmon-coloured suffusion of the abdominal one-third of hindwing. ?. Similar 

 but less suffused with salmon colour on hindwmg. 



Length of forewing : ^ 33 mm., ? 34 mm. Expanse : S 75 mm., ? 77 ram. 



Habitat. Rook Island, July 1913 (A. S. Meek), 5 (J(J, 3 ??.
