2/6 MR. KIRSCH ON BUTTIiRFLIES FROM TIMORLAUT. [Mar. 17, 



anticcB vena discocellulari late venisque secundariis usque ad 

 ramum mediance secundum (hoc solum dimidia externa) angustius 

 albo-limbatis, subtus ut supra; posticce medio plaga aureo-flava, 

 venis tribus in maculas quatuor extus profuiide emaryinatas, intus 

 prima et quarta leviter, sinualis, secunda et tertia {ilia versus 

 basin mugis attenuatu quam tertia) obtusis, extus juxta quartam 

 macula parvn albo-farinosa, serie intramurginali macularum 

 triangularium, interdum geminato-confluentium, fiava, magis 

 minusve atomatis nigris crebre conspersa, apice cellutcB discoidulis 

 macula Jlava minima (puncti/ormi) aut nulla ; subtus signaturis 

 iisdem, sed serie externa a margine posteriore magis remota quam 

 O. darsii et macula antica cellulce costalis linei/ormi. 



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, 2 . (Plate XIX. fig. 3.) 



Allied to D. alimena, var. velleda, Cr., from Aniboiua, 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 bauds is much narrower, because the outer band nearly reaches 

 the row of round bluish-white spots, at least at the anal half. 



Length of body 25, of (ore 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, inter- 

 rupted 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.
