Group II. — Antennae simple; fm-ewvngs tvit/i areole. 



Karscli, Ent. Xaclir. 1895. p. 347, divides this groui) in two sections, accordint; 

 to tlu- position of vein 10 to the forewings; this nervnle is either stalked witli 

 8 and 9, or it arises from the areole. These two sections do not seem to me to he 

 quite natural, as the following exam])les will show; but I accept them, as they are 

 certainly verj' convenient for a preliminary grouping of the genera. In Druce's 

 Agarista darna, Ann. Mac/. N. H. (6). XIV. p. 22 (1895), from Timor, the position 

 of vein 10 is so variable that we have specimens, caught at the same locality and 

 at the same time of the year, with vein 10 being stalked with 8 and 9, others 

 with vein 10 originating from the apex of the areole dose to the stem of 8. 9, and 

 others again with that vein coming from the areole and being distinctly separate 

 from 8 and 9. 



In the cJ of Hemtesia thyridion Boisd. veins 9 and 10 are shortly stalked to- 

 gether, while in the ? vein 10 arises from the areole independently of 9. 



The type of the genus Oi/irkt Westw., Oikrin avr/ias (H. S.),Ausii. Schrn. I. f. 18 

 (1853), comes in most characters very close to Phasis noctilvx Wlk., the type of 

 Phasia AVlk., Lep. Met. B. M. 11. p. 312 (1854), but has vein 10 originating beyond 

 the areole, while in Phasis it arises from the areole. K. ,1.

d. African forms. — Here come the genera Xardhosj/dopteryx Wllgr., Massarja 

 Wlk., Schatma Karsch (see Karscli, Ent. Nachr. 1895. pp. 345. 340). 



There are in the Tring Museum twenty-eight specimens of X. africnna Hutl., of 

 which four are aberrant in having an orange spot in the black marginal border to tlie 

 hindwings near the anal angle. In one of these specimens that spot is indicated, 

 under a lens, by four reddish .scales on the ui)perside of the left wing, while on the 

 right wing it is represented by about a dozen scales ; below, the si'ots are entirely 

 absent from either left or right hindwing. The second example has above on both 

 wings a very few scattered orange-red scales, whereas below the spot is well marked. 

 In the other two specimens the spot is conspicuous above and below. Out of twelve 

 specimens of X. fatima Kirby, five show a more or less obvious trace of that spot, 

 especially below. This proves, I believe, that the occurrence of such a spot cannot 

 be used to separate specifically specimens with and without that mark which are 

 otherwise the same. A', jierdri.v Druce ( = eoa !\Iab.) is, therefore, only an aberra- 

 tion of africana Butl., which itself is perhaps the red form of one of Walker's 

 species. 



We have a female of A', hornimunni Druce, from the Gold Coast, in which the 

 basal and median white spots are confluent with one another along the costal, median, 

 and submedian nervures, thus forming a large triangular patch that includes a 

 black spot in the cell and another behind it. The markings on the wings of 

 Xanthospilopteryx vary, in fact, a good deal. In A', snperha Butl., for example, tlie 

 s[K)t before the middle of the inner margin is in our series of twenty-three specimens 

 quadrate, or is pi-olonged along the submedian nervure, assuming the form of a broad 

 comma, sometimes merging together with the second spot of the post-median row, 

 or is reduced to a rather narrow oblique streak ; in one example this spot is quadrate 

 on one wing, linear on the other. The median band of A', hidler-i (Wlk.), of which 

 species we have fifteen specimens, is often complete, sometimes it is con.stricted at the 

 median nervure, and not t-arely it is even widely interrupted ; and so on. I fear that
