ANCISTROa'UIPTA; SPx\THILEPIA ; OECHYDRUS; THORYBES. By Dr. M. Draudt. 879 



C. calathana Hew. (170 g) in its colouring and marking entirely resembles T. alladius from which, mlathana. 

 however, it is at once discernible by the different shape of the wings. Central and South America. 



C. compusa Hew. (170 g) is above and beneath marked the same, only of a duller colouring, the trans- cotnpusa. 

 verse bands somewhat more distinct, without any yellow colour on the hhidwing. Amazon District. 



C. calanus G. <€• *S'. (173 a) is likewise similar to calathana, but it has much broader wings. The hindwing calamm. 

 is not produced so far at the anal angle and above only the fringes are ochreous-yellow. Known from Mexico, 

 Guatemala and Panama. 



37. Genus : Aiicisti'ocampta Fldr. 



In contrast with the neighboming genera, the antennal club is here only moderately thickened, at 

 the pointed end angularly flawed, not bent, and at the exterior edge it shows scanty, minute bristles. Costal 

 fold absent; on the forewing the upper median vein rises far before the lower cell-angle. Tlae posterior tibiae 

 armed with 2 pairs of spurs exliibit a bent hair-pencil. 



A. hiarbas Cr. (= ozias Hew.) (170 g) is above deep velvety brown with a large, yellow discal hiarbas. 

 hyaline spot narrowed on both sides, very much widened beneath at the proximal angle. The hindwing is 

 beneath brownish-or violettish-grey with a dark brown costal-marginal sjjot and such a transverse band from 

 the middle of the proximal margm to the costal-marginal angle. South America. 



A. celstis F. (= clearchus Plotz) (171 a) is similar, smaller, and the yellow discal band extends celsus. 

 in about the same width from the costal margin to the proximal angle; the under surface is just lilie above, 

 only of a duller brown. There are doubts about the nomenclature of this species and of the preceding. We 

 are of Godman's opinion that it is thus most correctly placed. South America. 



A. aniyrus Mab. is closely allied to hiarbas. The ground-colour is above and beneath uni-coloured amyrus. 

 black; the yellow discal band begins broadly at the costal margin and grows narrower towards the proximal 

 margin; beside it there is a similar, yellow subapical hyalme band divided into 6 small spots by the veins. 

 The palpi are dirty yellow, haired black. Colombia. Rio San Juan. 



38. Genus: Spatliilepia Btlr. 



Well distinguished by the shape of the wings with a very much projecting angle below the apex of 

 the forewing and a dentate border i^articularly on the hindwing, which is somewhat produced in the middle 

 of the distal margin and at the anal angle. Costal fold present. Posterior tibiae with hairy fringes and 2 pairs 

 of spurs. Only one species. 



Sp. clonius CV. (171 a) is above black with a white discal hyaline band, a series of minute apical donhis. 

 spots and between them with a small oblong spot. Beneath very variegated with the same marking of the 

 forewing as above, only the oblique band being much broader at the proximal angle. Hindwing brownish, 

 at the costal margin uiixed with bluish-grey and with large, dark brown spots bordered with light, the largest 

 at the costal margin triangular, with its apex crossing the cell and extending close to the proximal margin. 

 Very common from Mexico almost through the whole of South America. 



39. Genus: Oeeliydriis Wts. 



The shape of the wings is very much like in the preceding genus, but the margin is not dentate, but 

 entire. Costal fold present ; all the rest is like the Spathilepia, excejDt the hindwing of the J' exhibiting a hair- 

 tuft on the upper surface. 



0. chersis H.-Schaff. (= evelinda Btlr.) (171 a) shows above the same colouring and marking as chersU. 

 Sp. clonius, and there also exist resemblances beneath ; the apex of the forewing and a large discal spot on the 

 hindwing are reddish-brown; the costal margin and base are mixed with a bluish-grey. Brazil, Amazon. 



0. ochrilinea Schs. is the same, but the discal band is yellow. Described from Peru. ochr'dUwa. 



0. aziris Hew. (171 a) differs above by only one small hyaline costal-marginal spot and the absence aziris. 

 of apical spots. Tiie under surface is very variegated: forewing light reddish-brown, towards the apex speckled 

 with a whitish-grey, with some black antemarginal spots, the margin itself being more grey. Hindwing light 

 ash-grey with some dark brown spots partly tinted \\-hite on both sides. Rio de Janeiro. 



40. Genus: Tliorybes Scdd. 



The genus is closely allied to Cogia and chiefly differs by the absence of the hair-tuft on the hindwing. 

 Costal fold absent.
