similar to it also in in.icuhition, but still more like tbe description of 

 nevathv, with wliit-li it can hardly be identical. In jrenital structnre ii 

 is like atlanticn. The haipes are nioditicd toward tip into a cnrved 

 hook, lonjjer than in nthditica but of tlic same shai)e ; three smalk'i 

 corneous hooks of various shapes arise from the inner face of the harpe, 

 that nearest base the lon-^cst.

In ^Ir. l^dwards's collection is an imptrfect specimen witli this name, 

 and agreeing, so far as the maculation is traceable, with the above de- 

 scription. Tlu' specimen, however, has naked eyes, and is an JIadena 

 allii'd to citridta. The insect was so deternnned by Mr. Grote; but^ 

 as it is uot good enough to compare with all the details of the descrip 

 tion, it is retained here as unknown. Mr. liutler (in the Trans. Ent. Soc. 

 Loud., for 1881), ]). 385) refiTs this si)ecies to tluilassinn llbn.; but as 

 the reference is uot accomjianied by a critical comparison of tlu' spe 

 cies, I prefer not to accej)t it at present. It may be worthy of note that 

 Speyer (in Stett. Ent. Zeit. 3lj, 110) si)eaks of a specimen supposed to 

 be American, but without (b.'liinte locality, e.Kpanding 3(j millimetres, 

 and ditioring only in minor details from the European thnlassina.
