DESCRIPTION OF A NEW SPECIES OF LITHOCOLLl^TIS BRED 



FROM BIRCH. 



BY W. H. E. FLETCHER. 



Ltthocolletis anderid.^, ^7;. n. 



Antennae greyish ; palpi gi'ey externally, white internally ; face white ; head 

 saffron ; thorax with white and saffron scales, but owing to the damage done in 

 pinning, I cannot give their arrangement. Anterior-wings deep bright saffron, with 

 pearly-white markings, consisting of : — a short straight basal streak, dark-margined 

 on the costal side, at the apex, and one-third of the distance back towards the base 

 on the inner side ; a short streak from the base on the inner margin dark-margined 

 towards the costa, a fascia angulated on the side nearest the base, but less so on the 

 outer side, dark-margined on both sides ; three streaks on the costa, and two on 

 the inner margin, dark-margined on the side nearest the base, the last costal streak 

 being just over the dark apical patch ; cilia dark grey, shaded off to white opposite 

 the streaks. Posterior-wings grey, cilia grey, those on the costal side darker than 

 those on the liind-margin. Body saffron, with many pearly-white scales. 



Alar, exp., 2\ — 3 lines. 



Allied to Lith. Hremiella, lautella, and irradiella, from which it 

 may be distinguished by its smaller size and white face, from Lith. 

 ulmifoliella it may be separated by the brightness of the pearly-white 

 markings. 



The larva feeds in hirch leaves in October. 



I bred this species in the spring of 1880, of 18S3, and of 1885, 

 but each time only a very few specimens. No doubt I have overlooked 

 its small mine among those of young 0?'nix larvre. 



The species is named after the vast forest formerly surrounding 

 Pevensey (" Anderida "), of which Abbott's Wood may be regarded as 

 the heir-at-law. 



I have to thank Mr. Stainton for his kindness in examining 

 specimens. 



Fairlawn, "Worthing : 



June 1st, 1885. 



[I think I may add that the ground-colour of this new Lithocol- 

 letis is paler than in L. Breniiella, and the markings are white, not 

 silvery.— H. T. S.] 



A male Locust devoured ly a female. — In Dr. Horvath's " Rovartani Lapok " 

 for January, p. 18, E. Yangel relates that he reared to the imago-form two larvse of 

 the rare Locust, Onconotus Servillei, Fisch. ; that he fed them with a common grass ; 

 that one proved to be a male, and the other a female, which soon coupled ; and that 

 immediately after coupling, the female ate up the male. — Eds.
