A NEW SPECIES OF ARISTOTELIA BRED FROM HYPERICUM'. 

 BY TUE ET. HON. LOED WALSINGHAM, M.A., LL.D., F.R S. 



ARISTOTELIA, Hb. 



Aeistotelia mohphochroma, sp. n. 



Antennee pale brownish ochreoua, narrowly annulate with fawn-brown. Palpi 

 pale brownish ochreous, the median joint sliaded esternallj, nearly to its apex, with 

 fiiwn-brown. Head and thorax pale brownish ochreous. Fore-wings pale brownish 

 ochreous, always more or less shaded with fawn-brown, and with several small 

 fuscous spots upon their surface ; one at the extreme base of the eosta is succeeded 

 by a second a little beyond it, a third spot lying below the eosta at one-third from 

 the base; there are two in the fold, dividing it into equal parts, each of these 

 being slightly posterior to the costal and subcostal spots above them ; a strong 

 spot at the end of the cell is preceded by another on the cell at about an equal dis- 

 tance between it and the second plical spot, but in distinct line with the discal and 

 above the plical ; around the apex and termen at the base of the brownish ochreous 

 cilia are some fuscous spots, to the number of about four on the eosta, and tliree 

 more diffused on the termen, the latter at about one-third the length of the cilia. 

 Exp. al., 10 — 12 mm. Hind-wings brownish grey ; cilia brownish ochreous, but 

 rather greyer than those of the fore-wings. Abdomen brownish grey. Legs 

 brownish ochreous, the tibiae shaded with fuscous externally. 



Type, S (80,067); ? (80,04.3). Mus. Wlstn. 



Sah.: S. Feance— Cannes, larva Hypericum sp. {quadrangulare?), 

 IV. excl. VI. 1881 ; 16, IV. excl. 27, V. 1802. Italt— Eomc, larva 

 Hypericum sp., 9, IV. excl. 19, IV. 1893. Eight specimens (including 

 that in the Stainton Collection). 



This species appears to vary only in the amount of suffusion on 

 the wing-surface, this when excessive always leaving a pale costal 

 spot at the commencement of the cilia. 1 he larva feeds in April in 

 the stems of Hypericum {quadrangulare?), where it mines downward 

 from the leading shoot, causing the latter to droop and die, the leaves 

 becoming brown, and therefore conspicuous by the time the larva is 

 full-fed ; before pupation it leaves the mine and forms a slight cocoon
