248 Lord Walsingham on the Tortricidce, 



there is no evidence at present to support a conjecture 

 that Adela * electella may prove to be the female of 

 A. nataleiisis; indeed, the great difference of their 

 respective sizes renders it at least improbable, but, in 

 view of their similarity, it is worthy of notice that the 

 specimen is mounted in such a way as to render it 

 apparently impossible to determine its sex, although 

 Mr. Walker considered it to be a male ; and moreover, 

 that his examples of A. albicornis, which (as I pointed 

 out in the 'Proceedings of the Zoological Society,' 

 London, February, 1880, p. 78), is a synonym of Adela 

 natalensisy Stn., were received in the same collection and 

 from the same locality as his Micropteryx ? electella. 



HYPONOMEUTA, Zeller. t 



Ilyponomeuta africamis, Stn., Trans. Ent. Soc. Lond., 

 n.s., vol. v., p. 222; Walk., Cat. Lep. Het., 

 B. M., xxxv., p. 1824. 



Hyponomeuta siilplumlellus, n. s. (PL XL, fig. 16). 



Capite palpis et antennis plumbeis. Thorace plumbeo, 

 maculis quinque nigris in margine dispositis. Alis 

 anticis angustis elongatis subnitentibus punctis nigris 

 seriatim dispositis quinque sub costa ultra medium pro- 

 ductis quinque supra plicam et quinque supra mar- 

 ginem dorsalem minus extensis ; aliis minoribus ante 

 apicem singulis. Posticis plumbeo-cinereis quam anticis 

 vix latioribus. 



Head, palpi, and antennae lead-colour, the face slightly 

 paler. Thorax lead-colour, with five black spots, two on 

 each side, and one at the back. Fore wings lead- colour, 

 slightly shining, with three rows of about five small 

 black dots, one below the costa reaching beyond the 

 middle, and one on each side of the fold reaching 

 scarcely beyond the middle, one or two smaller black 

 dots beyond the end of the cell. Hind wings slightly 

 wider than the fore wings, leaden grey (not black). Ex- 

 panse, 18 mm. 



One specimen in Mr. Gooch's collection. 



This species is nearly allied to Hyponomeuta viginti- 

 punctatus, Eetz., but the fore wings are narrower and 

 more elongate, the spots smaller and not so numerous ;
