a new subfamily of Scolytide. 427 
matted condition of the long curled hairs which some- 
times occur on the front of the head in Scolytids. I have 
seen them in a condition curiously like the mandibles 
figured by Motschulsky, whom I believe, from examina- 
tion of other work of his, to have been capable of such 
an error. In 1885, Dugés described an aberrant genus, 
Chapuisia,* from Mexico, which he believes to have 
affinities with the Platypinit. At present I content myself 
with saying that its affinities are probably more remote 
than Dugés supposed, and that, so far from being aber- 
rant, it may be related to Coptonotus, Chap. 
In the very fine collection of Scolytide made in Japan 
by Mr. Geo. Lewis, which he has entrusted to me for 
examination, are three or four species of a remarkable 
kind, forming a closely-allied and compact group, which 
cannot be associated with any of the existing divisions 
of the family. In certain points they show a remarkable 
resemblance to Platypini; and though the dissimilarity 
of other structural features may indicate that the re- 
semblance is not so great as it appears to be, I have 
thought it desirable to treat them in a separate paper 
as forming the nearest allies to Platypi which we as yet 
know. 
Besides the Japanese species there is another from 
India, of which a male exists in the British Museum 
collection, and a female in Chapuis’ collection in the 
Brussels Museum. The latter was received after the 
publication of his Monographie, and was labelled by 
him, ‘‘ Platypide, gen. nov.” I have, therefore, his 
authority as to the probable relationship of these forms 
with the Platypini; but the definition of the latter sub- 
family cannot possibly be extended so as to include 
them. They must, therefore, form a distinct subfamily 
of the Scolytide. In 1891, C. Schaufuss described a 
form from Madagascar under the name Scolyto-platypus 
permirus, which he considered as a true Platypid. In 
this paper, when first written, I accepted his view, as 
borne out by the generic characters, and compared the 
species with my Japanese forms, as their nearest ally 
among Platypini. Since then Herr Schaufuss has very 
generously entrusted to me for examination one of his 
two examples of this insect. I find it most closely allied
