NEW BRITISH SPECIES IN 1858. 149 



Diasemia Ramburialis, Duponchel. 

 (Fig. 3.) 

 A specimen of this insect, which had previously only been 

 recorded as occurring at Vienna and Corsica, was taken at 

 Probus in Cornwall by Mr. Boyd, on the 16th of June," a 

 single specimen flying in a swamp at dusk" (Int. vol. iv. 

 p. 151). Duponchel states that it occurs in marshy places 

 in the Isle of Corsica, in April and August. 



Nola Centonalis, Hiibner. 



A specimen of this species, which may readily be distin- 

 guished from Cristulalis by the more stumpy anterior wings 

 and the different form of the elbowed line, was taken at light 

 on the 1st of July, at Bembridge in the Isle of Wight, and 

 w r as exhibited by Dr. Wallace at the August meeting of the 

 Entomological Society of London. 



Herrich-Schaffer has figured this species in his second 

 volume, figures 141 and 142. 



Acrobasis rubrotibiella, Mann. 



Two specimens of this novelty were taken by Mr. M'Lach- 

 lan flying round an oak tree near Forest Hill, and were ex- 

 hibited at the September meeting of the Entomological So- 

 ciety. 



The species is closely allied to A. tumiclella, but differs 

 from it in the following respects : — 



1°. The basal portion of the wing, instead of being orange, 

 is a pale grey, with a red streak along the costa ; 2". instead 

 of the broad orange band beyond the black first line there is 

 only a slender red band ; and 3°. the hind margin of the 

 wing is straighter and less oblique.
