CHLORIONA FARINOSA. 75 



Mr. Edwards says that the pupas of Liburnia unicolor, 

 L. forcipata and Stiroma pteridis show all the important 

 characters of AchrotUc ; and, further, that amongst 

 some hundreds of nymphs he examined, although he 

 could not decide on the species to which they belonged, 

 they exhibited the same tuberculose faces. 



Mr. Edwards discusses this question pretty fully in 

 the Ent. Mo. Mag. for August, 1885, p. 67, and he 

 thinks that we are not, and shall not be, in a position 

 to say that the genus Achrotile is British, until we have 

 more adult foreign examples to compare with. 



Nevertheless Boheman and Stal agree that Achrotile 

 is a good species, whilst other authors consider it to 

 be an undeveloped Delphacid of some undefined kind. 

 The Rev. J. A. Marshal believed it to be the larva of 

 Lihurnia neglecta. Mr. Edwards gives significance to 

 the fact that Lihurnia hrevipennis and Stiroma hivittata 

 may be taken together at the roots of dry grasses, from 

 the middle of August to the middle of October, after 

 which time they all apparently go down for hyber- 

 nation. 



Mr. J. C. Dale captured eight pupal specimens of 

 Lihurnia alhosignata in October, at Bonchurch, Isle of 

 Wight. Scott compared these, which were of both 

 sexes, with an insect given to him by Dr. Stal, and he 

 considered them all to be identical. He remarks on 

 the white margins to the basal abdominal rings as 

 characteristic.
