 truncata Moore, Ann. Mag. N. IJ. (4) xx. 50-51, $ (1877). [This seems to be a form of acuta. 



I have had no ^ to examine.] 

 paraeuta Nic^v. = acuta Pryer nee Moore, Journ. Bomh, N. II. Soc. xiv. p. 248 (1902). 



Ue Nic^ville says acuta Moore = truncata Moore = angulata Moore. Bnt 

 paraeuta, though it looks very dilFerent from acuta, agrees with that species as to 

 the appendages, and must be regarded as the geographical race of that species 

 inhabiting China, Formosa and Japan rather than as a distinct species. 



angulata Moore, Proc. Zool. Soc. Loml. 1883, p. 522 pi. xlviii. fig. 2 (an angulated form of buVs 

 much resembles and passes for angulata). 



My own specimens of "a>iffulata" from several sources all prove to be bulis ; they 

 were named no doubt from the form of the wings, and these angulated specimens 

 of bulls are very similar indeed to true angulata, which, from its habitat (N.W. 

 Himalayas) and its having a ? with white patches, is no doubt a form not of 

 huUs, but of acuta. 



acuta var. brunnea Wileman, Annnl. Zool. Jap. vii. p. 88 (1909). 



I do not know whether this is a distinct race of paraeuta, or is aberrational. 

 In the preparation (and photograph) the aedeagus has unfortunately got 

 crushed towards the extrcmit}'. 

 I should define 



acuta: 1. Stigmatal mark distinct. 



2. Harpe expanded at tip. 



paraeuta : 1. Stigmatal mark lost in the black area beyond it. 



2. Harpe pointed at tip. 



I see no objection to any one regarding these as good species, though I think 

 it seems better to consider them geographical races of one species. 



C. acuta differs from bulis in being usually provided with the dark tooth 

 {dentata, stigmata) or stigma projecting from the costal dark border into the copper 

 area. The angulata form of bulis is as angulated as any acuta, but acuta is 

 usually angulated, bulis round-winged. On the underside, the oblicpie postdiscal 

 line, which in these two species is more or less straight, in the t/ietis section 

 Innulated, is comparatively, at its lower termination, decidedly farther from the
