S0LEN0BIA CLATHRELLA. 197 



denselben cloch auf meinen Exemplaren schwach angedeutet, aber 

 nicht so stark, als er es bei der ihr sonst, auch in der Grosse und 

 Gestalt sehr ahnlichen pilulella, Hb., fig. 409, ist. Das Weib ist mir 

 unbekannt, nach Treitschke soil es glanzend schwarzbraun sein, eine 

 schwarze Legerohre und etwas weisse, nach Zincken aber gar kerne 

 Afterwolle haben. Dieses bewiese wieder, dass Zincken's Art nicht 

 meine triqitetrella ist, weil diese letztere ziemlich viel weisse Afterwolle 

 und eine hellbraunliche Legerohre hat, wodurch sie sich auch von 

 clathrella unterscheidet. Es miisste denn der Fall sein, das Zincken 

 ein Weib vor sich hatte, an welchem durch das Eierlegen die After- 

 wolle schon verloren gegangen war. Das Weib, welches Hubner, neben 

 dem Mann abbildete, ist so klein, dass die Legerohre und Afterwolle 

 nicht bemerkbar gemacht werden konnten, aber eben diese Kleinheit 

 beweiset wieder, dass es nicht zu clathrella, gehoren kann, weil dessen 

 Weib viel grosser sein muss ; das meiner triquetrella ist aber wirklich 

 so klein, wenigstens nicht viel grosser (Fischer, Abbilclungen Ber. 

 Erejanz. Schmett. Microlepidnptcrologie, pp. 84-85). 



N.B. — Zeller notes Fischer's figure as recognisable for the species, but failing 

 in shape and colour. He confirms Treitschke (and contradicts Fischer) that the 

 forewings have a metallic gloss. Guenee notes that it has " mac. cellularis nulla," 

 and Fischer figures no discoidal lunule, but Zeller notes that one is present. He 

 further considers Duponchel's figure recognisable, and states that according to the 

 larva it can be no other. Duponchel distinguishes his <S'. clathrella from <S'. 

 lichenella in that the former has the forewings of a paler grey, and with a slightly 

 reddish tinge. Zeller thinks Tengstrom's S. clathrella was probably ;S'. pineti, but 

 gives no reason for the supposition. 



Imago. — Anterior wings 16mm.-17'5nim. in expanse ; dark grey 

 (resembling pineti in its depth of colouring) ; specklings but little paler 

 than ground colour (hence very unicolorous in appearance) . Posterior 

 wings and fringes dark grey (Stainton coll.). 



Supposed British example of S. clathrella. — Dr. Mason has a 

 specimen of S. clathrella, slightly browner in tone than any in the 

 "Stainton" and " Frey " collections, otherwise in size, shape, and 

 general appearance, especially in the rough, brown head, and rather 

 thickly clothed abdomen, identical with two examples in the " Stain- 

 ton " collection (received from Mann, and bred April 1850 from larva) 

 found at Vienna, on sloe). The large size and wing shape make it 

 impossible for the specimen to be anything but clathrella or mannii, 

 and, although the pale mottling of the forewings is exceedingly well- 

 marked, we have no hesitation in referring it to clathrella. Except that 

 it is supposed to have come from Sang, Dr. Mason has unfortunately 

 no information to offer about the specimen. 



Sexual dimorphism. — Male : The head covered with dark grey- 

 brown hairs, which stand out all over it ; antennae of length of abdo- 

 men, fine, weakly dentated towards brown tip, fringed with pale grey 

 hairs, white-grey on dorsal area, the bases of joints dark ; body black ; 

 thorax and abdomen sparsely haired, the anal end thickly clothed Avith 

 light hairs ; legs, hairy, brown, with white-grey tips (to 1st pair) ; 

 forewings 3'75'"-4'" in expanse, somewhat elongated, slightly convex 

 on middle of costa, wing apex strongly rounded. Ground colour pale 

 grey-brown, not shiny, darker at base and along the costa ; a number 

 of small, pale grey spots give a latticed appearance to the wing, more 

 distinct towards bind margin. The principal nervures and nervules 

 somewhat darker than the ground-colour, forming line lines but not at
