Sp. 22. roborella, Zeller (fig. 22). 



Lithocolletis roboris, Zeller, Isis, 1839. Linn. Entom. i. 174, fig. 4. 

 Elachista roborifoliella, Duponchel, Sup. iv. 342, PI. 78, f. 11. 



Expansion of the wings 3| lines. Head snow white. Forehead snow white. 

 Palpi snow white. Antennae white, annulated with fuscous. Thorax white, with two 

 golden bands, one on each side of the middle. Abdomen fuscous. Legs and tarsi 

 silvery white. Anterior wings silvery white ; at the base is a golden oblique fascia, 

 commencing on the costa, where it is broadest, and terminating in a point about the 

 middle of the inner margin ; on the costa near the apex are three short golden streaks, 

 the first pointing outwards, the other two inwards ; on the inner margin is a golden 

 streak, meeting the first costal streak, and forming with it a right angle : at the apex 

 is a somewhat triangular black spot ; the space between this spot and the anal angle 

 is suffused with golden : cilia silvery white, but with two dark patches opposite the 

 last two costal streaks, and with a strong black line opposite the black spot. Posterior 

 wings pale fuscous ; cilia long silvery white. 



I have only seen one British specimen, which was taken by Mr. Bedell (he be- 

 lieves off an oak) on Leatherhead Common, September 28th, 1845. 



Zeller says of it, " It occurs at Berlin, near Frankfort-on-the-Oder ; and Glogau, 

 in young oak woods, sometimes plentiful, in two broods, of which that from the mid- 

 dle of April and in May produces the finest specimens. The second brood appears at 

 the end of June and in July, sometimes also still later. Tischer found the species at 

 Dresden ; Mann near Reichstadt, in Bohemia, very scarce ; oftener near Vienna, and 

 certainly here on oaks and maples. The caterpillars, which I have not yet observed 

 very closely, live in the under leaves of the oak (Quercus pedunculata). The part of 

 the leaf frequented by it is shown by the dappled upper side, because the caterpillar 

 consumes the leaf the least in the middle, only marking the leaf here and there. On 

 chrysalizing it makes itself a fine silky cocoon in its habitation. The little black pu- 

 pa, on the creeping forth of the moth, presses through the under half of the epidermis. 

 Sometimes several caterpillars live in the same leaf, each in a separate rib. Of two 

 living together in one leaf, one moth came out on the evening of the 30th of June, 

 the other on the morning of the 1st of July. Of the autumnal brood, there appeared 

 in my room specimens in January, along with Tischeria complanella.* That the ma- 

 ple (Acer campestre) also serves as food to L. roboris, appears to follow from Mann's 

 communication."
