Show 276 MR. KIRSCH ON BUTTERFLIES FROM TIMORLAUT. [Mar. 17, anticce vena discocellulari late venisque secundariis usque ad ramum medians secundum (hoc solum dimidia externa) angustius albo-limbalis, subtus ut supra; postica medio plaga aureo-ftava, venis tribus in maculas quatuor extus profunde emarginatas, intus prima et quarta leviter, sinuatis, secunda et teriia (ilia versus basin magis attenuata quam tertia) obtusis, extus juxta quart am macula parva albo-farinosa, serie intramarginah macularum triangularium, interdum geminato-confluentium, flava, magis minusve atomatis nigris crebre conspersa, apice cellula discoidalis macula flava minima (punctiformi) aut nulla ; subtus signature iisdem, sed serie externa a margineposteriore magis remota quam O. darsii et macula antica cellulce costalis lineiformi. This is a very distinct species, allied to O. darsius, Gray, and O. criton, Feld., but differing in the above particulars. I have named this species in honour of Mr. Riedel, to whom the Dresden Museum is indebted for so many valuable additions. 2. DIADEMA ALIMENA, L., var. SALVINI, $ . (Plate XIX. fig. 3.) Allied to D. alimena, var. velleda, Cr., from Amboina, and to D. forbesii, Butler, from Timorlaut. On the upper side the blue band, traversing both wings, very much resembling the typical form of D. alimena, but differing in the white markings being'throughout larger, also the interstice between the submarginal spots and the inner row of points much smaller. The differences become more remarkable on the underside, viz. fore wing : the two posterior spots, situated between the median branches, are surrounded by blue atoms, and the blue band, crossing the median nervules, is not continuous, but here and there rather evanescent; hind wing: the dark interstice between the two white cross bands is much narrower, because the outer hand nearly reaches the row of round bluish-white spots, at least at the anal half. Length of body 25, of fore wing 40 millim. 3. ATHYMA GRACILIS, nov. sp. (Plate XIX. fig. 4.) Male. Upper side smoky black, markings creamy-white; fore wing with two oblong connected spots, oblique from costal margin near the apex, and with four, forming a cross band, which reach the middle of the posterior margin (the three first spots subequally, the fourth narrow and somewhat longer), finally with an ill-defined marginal and submarginal spotted line. Hind wing with broad white inner band, covering the middle third, and with a narrow outer band nearly evanescent. Underside dusky ferruginous; markings the same as above, but the fore wing with a discoidal streak, straight, small and long, interrupted near the apex ; the hind wing at base of costa and mediana white, the marginal lines more defined and all white. Length of body 15, of fore wing 21 millim. Allied to A. venilia, L., but more slender, the broad white inner band relatively much larger. |
