Sp. 32. padifoliella, Hubner (fig. 30). 



Tinea padifoliella, Hubner, Ti. 316. 

 Lyonetia padifoliella, Zeller, Isis, 1839, 216. 



Expansion of the wings 5 lines. Head white. Forehead white. Palpi white. 

 Antennae deep fuscous. Thorax white. Abdomen pale fuscous. Legs pale fuscous. 

 Tarsi dark fuscous, spotted with white. Anterior wings white, with a broad brownish 

 band extending from the base to beyond the middle ; it is straight on the side towards 

 the costa (which it approaches very closely), till near its extremity, when it curves down- 

 wards ; on its side next the inner margin, where its colour is always deepest, it is much 

 sinuated ; at its extremity it meets a very oblique and curved fascia, the lower half of 

 which is much deeper in colour than the upper half; this is followed by a white patch 

 on each margin : the apex of the wing is dark fuscous, terminating in a hook, as in 

 the preceding, and with a black dot at the extreme apex : cilia whitish, with three 

 fuscous patches proceeding from the costa, a strong black line from the apex, a dark 

 curved line round the apex, and two wavy lines opposite the hinder margin. Posterior 

 wings clear gray; cilia grayish, with a violet tinge. 



A local species, taken by Mr. Desvignes, in September, in Whittlebury Forest, off 

 maple and whitethorn. 



Sp. 33. rhamnifoliella, Tischer (fig. 33). 



Elachista rhamnifoliella, Tischer, MSS. Fischer von Koslerstamm, Abbildungen, 

 ii. Heft. S. 10, lib. 7, fig. a—m. Duponcbel, xi. 522, PI. 307, f. 11. 

 Lyonetia rhamnifoliella, Zeller, Isis, 1839, 216. 



Expansion of the wings 3f— 4 lines. Head white, with a few fuscous hairs. Fore- 

 head white. Palpi white. Antennae white, annulated with fuscous. Thorax white. 

 Abdomen fuscous, with the extremity paler. Legs white. Tarsi white, annulated with 

 black. Anterior wings white, with fuscous irrorations, and two fuscous patches on the 

 costa ; one before, the other beyond the middle, both slanting towards the anal angle ; 

 on the inner margin near the base is a small dark patch, and about the middle a larger 

 dark patch, sometimes joining the opposite one from the costa ; there is a conspicuous 

 black dot on the inner margin of this patch ; the apex of the wing is occupied by 

 another fuscous patch, with a black dot immediately before it, and another at the ex- 

 treme apex : cilia pale fuscous, with a dark arch round the apex of the wing. Poste- 

 rior wings gray; cilia grayish brown. 



This occurs in plenty at Sanderstead, in July, on the buckthorn. 



It appears, from the most interesting account of the transformations and habits of 

 this insect, given by Fischer, " that the caterpillar is very abundant on all species of 

 Rhamnus, sometimes as many as a dozen on a single leaf." They however keep " on 

 the underside of the leaf, the surface of which they eat, producing many holes." 

 " When they are full grown they are scarcely a quarter of an inch in length. Their 

 colour is greenish yellow, and in most specimens the three first segments are tinged 

 with reddish brown." At the end of September it spins a cocoon, " which it fastens 

 to the twigs, stem, leaves, or to moss ; in this cocoon it passes the winter, and in 

 February or March is transformed into a chrysalis. The perfect insect appears at the 

 end of May or in the course of June."
