Somoeowma, Curt. — In the Isis of 1839 Zeller proposed for this 

 genus the name of FJiycidea, but in the Isis of 1848 he adopted that 

 of Homceosoma of Curtis, this name having priority. 



Homoeosoma nehuleUa, S.Y. — The larva has been described as 

 feeding in the heads of thistles. Wood figures a hintEvella (fig. 1451) 

 instead of a nehulella. 



Sommosoma nimhella, 7i. — The larva is well known, and feeds in 

 the heads of a great number of composite plants. The insect varies 

 very much in size and markings. 



* Homoeosoma saxicola, A'^augh. — This appears to be the most fre- 

 quent form of nimbella in England. I have a number of British 

 nimheUa from Yarmouth, Yorkshire, Cheshire, Pembroke, and Dublin, 

 and none are like continental specimens of that species ; saxicola is 

 generally larger, the fore-wings are more distinctly white on the 

 costa, and the rest of the wing is of a pure ochre, not at all powdered 

 with black scales as in the type of nimheUa. The name of saxicola 

 should be retained to distinguish the English variety of nimheUa. 



* Homceosoma senecionis, Yaugh. — This is a distinct species, but 

 it had already been described by Dr. Eossler in 1866 as H. cretacella. 

 The larva has been described by Mr. Buckler (Ent. Mo. Mag., vol. vii, 

 p. 131). It feeds in a tubular gallery among the flowers of Senecio 

 jacohcBtt. I have seen Dr. Eossler's original types from Wiesbaden, 

 and specimens from Metz and Siberia. 



Homoeosoma hin(Evella, Hb. — The larva feeds in the heads of 

 thistles, and has been described by J. von Hornig in 1853, and Barrett 

 (Ent. Mo. Mag., vol. xv, p. 181). 



Homoeosoma sinuella, Eab. — The larva feeds in the root stalks of 

 Plantago lanceolata, and its life history has been given in this Maga- 

 zine, vol. XV, p. 180, by Mr. Barrett. The perfect insect varies 

 somewhat in the neuration. 



Acrohasis consocieUa, Hb. — The larva lives in long, narrow, tubular, 

 silken galleries (covered with its excrements) between voluminous 

 bundles of oak leaves drawn together, and has frequently been de- 

 scribed. 



* Acrohasis sodalella^ Z. — Mr. Barrett notices this species in the 

 Ent. Mo. Mag., vol. xix, p. Ill, and concurs in the oj^jinion of Zeller 

 that sodalella is only a variety of consocieUa. I am not sure he is 

 right, for besides the differences which Mr. Barrett finds in the perfect 

 insect, there is a considerable dissimilarity in the larvae. That of
