rior, iiec Fieb., O. cinerea, Pieb., being Tingia nigrina, Fall.,=ilf. 

 intermedia, Flor (the last, however, ie reckoned by Tliomson as=0. 

 plaiycUla, Eieb., vide E. M. Mag., x, 187, 2, and 243, 2). Thomson, 

 Opusc. Ent., iv, 400, 3, says that T. ptisilla, Fan.,=0. pusilla, rieb.,= 

 T. nigrina, Fall. ; he takes no notice of O. macrophtliahna, Fieb., but 

 describes the species as new, under the name of O. cylindricornis. 



Dr. J. Sahlberg has kindly sent me exponents of O. viacropMhalma 

 and O. nigrina, Fall., which appear to be distinct species, the former 

 having black antenna?, and only 2 rows of reticulation on the sutural 

 area of the elytra ; the latter having the antennae thinner, and the 2nd 

 joint reddish-yellow, and the elytra with 3 rows of reticulation on 

 the sutural area, both being otherwise very much alike. It seems, 

 therefore, that, as there is no doubt our species is O. macrophthahna, 

 Fieb., the only safe way at present is to adopt this name, leaving the 

 synonymy to be investigated hereafter. 



A single example of the undeveloped form, from the collection 

 of the late Mr. T. J. Bold, was taken by Mr. J. Hardy, in moss on 

 Cheviot, in August. It is the species recorded as O. cervina in the 

 " Natural History Transactions of Northumberland and Durham," 

 p. 354, 24 (1872), as I was informed by Mr. Bold.
