INSECTS OF SAMOA. 



specimens from Woodlark and Rossel Islands and N. Australia, and it is there- 

 fore justifiable to question the origin of the type in question. But, in view of 

 the range of such species as Micrulia tenuilinea (supra), I cannot reject it utterly, 

 especially considering the high degree of accuracy shown in the labelling of 

 specimens in the Tring Museum. The Woodlark and Eossel have the blackish 

 patch on the end of the abdomen above rather more extended than in those 

 from Queensland and Samoa. Both forms vary in the depth of the ochreous 

 suffusion of the hind wing. 



Warren's Gymnoscelis semiviridis was extremely badly described, and the 

 species has not the remotest connection with G. coquina ; but since the author 

 in question expressed a suspicion that it might prove to be a distinct species, 

 his name must be regarded as valid. 



Ziridava Walker. 



List Lep. Ins., xxvi, 1550, 1862. — Hampson, Faun. Brit. Ind., Moths, iii, 391, 1895 (Chloroclystis 

 sect. Liridava [sic]). — Swinhoe, Ann. Mag. Nat. Hist., (6), xvi, 295, 1895 (Xiridava [sic]). 



This genus has, perhaps with justice, been merged by some systematists, 

 in Chloroclystis, but seems to be a collateral development. Face with long and 

 sharp cone. First segment of palpus with strong scale-tuft beneath, second 

 segment with strong downcurved scale-tuft distally beneath. Wings elongate, 

 coloration not green, SC 1 anastomosing with C, but without the pronounced 

 tendency to remain coincident with it thereafter. 



Two sections, according to the $ antenna, have hitherto been known. 



A. Antemia of pectinate : Z. rufinigra Swinhoe (1895, Khasi Hills), with 

 a race brevicellula Prout (191G, D'Entrecasteaux Is. ; also known to occur 

 in New Guinea), and a second race, at present unnamed (N. Queensland). 



B. (Sect. typ.). Antenna of $ dentate-fasciculate : Z. xylinaria Walker 

 (1862, Sarawak ; also found in N. India, Malaya, Java, ? Bali), with provisional 

 races subrubida Warren (1897, Celebes), leptomita Turner (1907, N. Queens- 

 land ; also known to occur in New Guinea, D'Entrecasteaux Is., Louisiade 

 and Bismarck Archipelagos, and the Solomon Is. ; possibly susceptible of 

 further subdivisions), and perhaps a fourth race (? sp. div.) found in Flores. 



To these must now be added Sect. C, with $ antenna simple, for the 

 reception of the following species.
