fore-wings, coalesced, into one. This specimen was shown to Mr. 

 •Stainton in May, 1892, and, after inspecting it, he quite allowed 

 that triffuttell a could not stand as a distinct species. It will be noticed 

 that in Mr. Stainton's descriptions of faginella the white basal streak 

 is said to be " un-margined," whereas in triguttella.it is given as 

 "dark-margined on both sides," but, as I pointed out to him, faginella 

 frequently has the white basal streak dark-margined on the upper- 

 side, and occasionally on both sides, and I have seen many in which it 

 is quite as darkly-margined as in Mr. Douglas's triguttella. Last 

 spring, when looking through the numbers oi faginella in Mr. Mason's 

 collections, I came upon a most interesting and extraordinary variety 

 of that insect. On the right fore- wing there are only three white 

 costal streaks : the first and second almost unite, and there is but 

 little dark scaling between the second and the third, which latter is 

 abnormally large, being formed by the coalition of the typical third 

 and fourth streaks. The left fore- wing has the first costal streak as 

 usual, but the second, third, and fourth have all coalesced, and form 

 one long white patch, which occupies a large portion of the costal area 

 and of the disc towards the apex. On both fore-wings the usual first 

 and second white dorsal streaks are present, but the third cannot be 

 separately traced, because the entire portion of the wing, as well as 

 the fringes, round the anal angle is pure white ! From the setting I 

 feel pretty sure that the specimen was bred by the late Mr. John 

 Sang, but am afraid that the locality will remain unknown.

NOTE ON PLATTCEPRALA OLIVIEEI, MONTE. 

 BY D. SHAEP, M.B., M.A., F.R.S. 



This genus and species was established (Ann. Soc. Ent. Fr., 1861, 

 p. 268) by Montrouzier for an insect found " under bark " in the 

 island of Lifu, New Caledonia. It was placed by Montrouzier in 

 LathridiidcB, " near ISIonotoma.^'' M. Fauvel, in his interesting work 

 on the Coleoptera of New Caledonia, stated (Rev. d'Ent., x, p. 154) 

 that this insect belongs to the genus Proterhiniis, recently established 

 by me for some insects believed to be peculiar to the Sandwich Islands. 

 My attention having been by this attracted to the subject, I applied 

 to M. Fauvel for some further particulars, and he kindly placed me 

 in communication with M. Grouvelle, in whose possession is the type 

 of Montrouzier's description. Mr. Grouvelle has indeed been so kind
