As abcady stated, 1 propose removing the two Madeiran in- 

 sects bitherlo regarded as llhijiicoll into the genus I'/ila-oplinguSf 

 their elongated antenna; and rostra (as compared with the Rliyn- 

 cvll proper), laterally-rounded prothorax, somewhat linger club 

 and less compact funiculus-joints (the second one of whicli, more- 

 over, is distinctly longer, vide 18, 4a, than the third), agreeing better 

 with the published diagnosis of the latter than with that of the 

 former. So that we shall have, up to the present date of dis- 

 coveries, only a single Rliyncohts in the Atlantic islands, namely, 

 the R. crassirostris, from the Canaries ; whilst of the Phlccopliagi 

 there will be three in the Madeiran- and five in the Canarian- 

 groups. These "five" latter ones constitute a small geograpliical 

 assemblage, and are very closely related mter sc, being at first 

 sight scarcely separable from each other. Nevertheless theu- 

 characters are in reality extremely constant, and are not the less 

 real because they happen to be (for the most part) microscopic, 

 and thus far, therefore, difficult of observation. At least I can 

 affirm with truth that, in com[)iling their diagnoses, I have exa- 

 mined most critically upwards of 300 specimens, and that 1 have 

 not found a single individual which has left me in the slighest 

 doubt as to the precise type to which it belonged; though it is 

 certainly an open question whether one or two which I have 

 thought it safer to record as varieties may or may not hereafter, 

 when further material is amassed, be considered to rank as ad- 

 ditional species.

The P. sulcipennis has occurred hitherto only in Madeira proper, 

 where, until numerous examples were found two years ago by 

 Sr. Moniz in his garden at Funchal, I had considered it extremely 

 rare — the only specimens in fact which I had seen being two 

 which were collected by the late Dr. Heineken. But, since
