femurs toothed and thickened, and the joints of the tarsi tri- 

 angular and subequal. 



Lansberge founded the genus Octodon, in which he placed 

 Aieuclms mnltidentafum, Klug, but, owing to the name being pre- 

 occupied (Mammalia), Ritsema changed it to Mneinatidium.. 

 Bedel, evidently not having seen Ritsema's name, called it 

 Neoctodon, which however cannot stand. Lansberge's descrip- 

 tion of the genus reads thus : — " Qui se compose des especes a 

 corps aplati et parallele, a cuisses anterieures dentees a ecusson 

 apparent et a articles des tarses triangulaires subegaux."

NOTE ON EUMESTLETA, Butl., &c. ; A GROUP OF 

 NOCTU^ OF THE EUBLEMMINE TYPE. 



By a. G. Butler, Ph.D. 



I FOUNDED this genus ('Entomologist,' xxv. 189) for the 

 reception of Aiithoi^hila flammicincta, Walk., and allies ; it has 

 the general aspect of Mcstlcta, and agrees with it in leg structure. 

 At the time when I indicated this group and the species referable 

 to it, the allied genus Mestleta was placed among the Deltoid 

 moths, and therefore I naturally concluded that if one group was 

 rightly placed there, the other ought to follow. Mr. Hampson 

 has subsequently shown that Mestleta is a genus of true Noctuas 

 allied to Tarache and neighbouring genera, and not a Deltoid. 

 My natural conclusion, based upon a false foundation, therefore 

 naturally falls to the ground. 



How Prof. Smith failed to see our series of twelve specimens 

 of this species, I do not understand. The genus was arranged 

 long before he examined the collection and in the Enhlemmine 

 group, from which I never removed it, but to which I subsequently 

 transferred Mestleta and allies. 



Eumestleta differs from Mestleta in its palpi, the second joint 

 of which is shorter and more densely fringed in front, making it 

 distinctly broader, and in the long fringes to the middle and 

 posterior tibine. In pattern it is very similar. 



The structure of the legs in " l^halpochares mundida" and 

 " T. latipalpis'' is very dissimilar, and the pattern and coloration 

 more nearly resemble those of many species of Metachrostis.
