NEW BRITISH SPECIES, ETC., IN 1870. 37 



superficial resemblance to a small H. monilicoinie^ with which 

 species alone Erichson compares it ; it is, however, more 

 closely allied to H. vile, as Kraatz notes;— from which it 

 may be known by its decidedly larger size, more robust and 

 broader build, more shining thorax, stouter antennae, and 

 stronger punctuation, that of the elytra being more confused, 

 almost rugulose in places, and not forming occasional strias. 



29. HoMALiUM GRAciLicoRNE, Fairm. etLab.; E.G. Rye, 

 Ent. Ann., 1870, p. 88; /. c, vol. vii, p. 153. 

 Only the London -district specimen mentioned in my 

 original recoi'd of this species appears to be rightly so re- 

 ferred ; it bears considerable superficial resemblance to an 

 immature specimen of the narrow form of Pliilorhinmn 

 subjmhescens {humile, Er.), and is rather larger than JS. vile, 

 much lighter in colour, with stronger and not so close punc- 

 tuation on the thorax, the sides of which are more rounded 

 and which has no dorsal depressions, and with the punctua- 

 tion of the elytra coarser and not so close, — not forming 

 occasional striae. Compared with type H. hi'evicorne, it is 

 smaller, narrower, lighter, with no dorsal depressions on the 

 thorax, the sides of which are more rounded and less con- 

 tracted behind, the two basal joints of the antennae are not so 

 stout, and the sub-apical joints not so transverse, the punc- 

 tuation of the elytra is not so close, and the abdomen is not 

 so shining, being more coriaceous. Dr. Power has recently 

 given me some further specimens of //. hrevicorne from 

 Balmuto, w hich diflrer slightly from the two examples above 

 mentioned from the same locality. The smallest of these 

 further specimens resembles my gracilicorne in having 

 scarcely a trace of the usual thoracic depressions; but 

 the structural and colour differences above specified still 

 remain.
