New Geometridae from Central Ceram 297 



29. Arycanda botipis sp. no v. 

 ? . 42 — 45 mm. 



Face grey. Palpus and vertex darker grey. Thorax and abdomen 

 grey, shaded with bluish, especially dorsally. 



Fore wing relatively rather short ; cell fully one-half ; glossy light 

 grey-blue, the costal margin somewhat irrorated with black, especially 

 at base ; some black spots or rudimentary lines near base ; lines black ; 

 antemedian at one-fifth, not very strong, more or less macular ; very 

 large (circ. 3 mm. in diameter) deep black cellspot, shortly followed by 

 the postmedian line, which is nearly perpendicular from costa to E 3 , 

 here augled, then gently incurved, and is very fine and weak except at 

 the veins, where it is cut by longitudinal short dashes or dots ; a very 

 broad black border, nearly reaching the postmedian ; fringe grey, 

 mottled with black. Hind wing with cell ^ or slightly over ; as fore 

 wing (the cellspot slightly less large). Underside without the lines; 

 cellspots and borders as above. 



Central Ceram, 4,600 feet, January, 1920, type and three other 

 ? ? in coll. Joicey ; also a rather smaller example of the same sex 

 (38 mm.) taken at 3,000 feet, January to February, 1920. 



30. Arycanda tenebrica sp. nov. 

 8 ? . 40—50 mm. 



Head and body mixed slate-grey and brown-grey, anal tuft tinged 

 with ochreous ; abdomen dorsally with indication of paired dark spots. 

 Antennal ciliation in 8 slightly over 1, in ? slightly under 1. 



Fore wing with fovea in 8 rather less strong than in hypanis 

 Cram., in ? almost wanting ; slate-grey, darker than in hypanis, the 

 black markings numerous and heavy ; vague basal irroration or macula- 

 tion ; a subbasal band of rather large spots, acutely angulated outward 

 in cell, then oblique inward ; a thick, curved, antemedian line ; a rather 

 large cellspot (less large than in hypanis) ; the succeeding line still 

 more excurved round cellspot than in hypanis, incurved to fold ; two 

 rows of long thick interneural marks beyond, weakened — especially the 

 distal— in cellule 3, sometimes partly confluent, the distal row reaching 

 the subterminal ; terminal interneural marks, less strongly developed 

 than in hypanis ; fringe concolorous. Hind wing with the costal 

 margin almost as clear as in hypanis, unmarked as far as postmedian 

 line, the rest concolorous with fore wing ; median (antemedian) line 

 curved or bent ; cellspot and markings beyond nearly as on fore
