NEW BRITISH SPECIES IN 1858. 153 



blue streaks is a large yellow spot on the costa ; cilia dark 

 brown, but the tips of the apical cilia white. 



This conspicuous and pretty species has long held a place 

 among the reputed British insects, and is figured in Wood's 

 Index : its recurrence was recorded in the " Intelligencer," 

 vol. iii. p. 179, Mr. Backhouse having sent me for exa- 

 mination a specimen, " which was taken near Gateshead, 

 along with two or three more, by a young collector in a 

 garden, flying about some old tree stumps, in the summer of 

 1857." Mr. Backhouse has very liberally enriched my 

 Collection by the addition of this species. 



The larva is a rotten-wood feeder, and I had no doubt fed on 

 the old tree stumps. I have received it from Herr Grabow, 

 of Berlin, feeding in the bark of mulberry trees. 



Glyphipteryx Cladiella, n. sp. 

 Alis anticis saturate viride ceneis, strigulis nullis, pone me- 

 dium nigro-striatisj angulum analem et apice?n versus 

 nigro-squamato, 

 Exp. al. 6 — 61 lin. 



Allied to G. Thrasonella, but with no silvery streaks. 

 This species has been collected during the two past seasons 

 by Mr. Bond, in Wicken Fen, near Cambridge; the spe- 

 cimens do not vary, so that it does not appear to be a form 

 of Thrasonella. It was taken flying singly over the tall 

 sedge; and, as that fen abounds with Cladium mariscus, I 

 should not be surprised to find that the larva feeds on the 

 seeds of that plant. 



Glyphipteryx Schcenicolella, Boyd. 

 Alis anticis angustulis saturate ceneo-griseis, strigula angusta 

 cwvata ex medio dorsi, strigulis posticis quinque costce,
