428 Mr. Blandford on the Scolyto-platypini, 
to the Japanese species, and examining it in the light of 
those insects, I note that in two essential points—the 
number of joints in the antennal funiculus, and the 
length of the first tarsal joint—his description is 
erroneous. In these points his insect does not corre- 
spond with the Platypi, and it must be grouped with the 
Japanese forms as distinct. But the sight of this insect 
has increased my difficulties with regard to generic 
classification. The several species, though most distinct 
in male characters, show little signs of difference among 
the females; and S. permirus appears to be intermediate 
between the two genera I had constructed. As I cannot 
dissect the type, which is somewhat mutilated, and have 
not seen the male, I think it better to unite the species 
under the general name of Scolyto-platypus, while indi- 
cating the genera I had founded on the Japanese species, 
as being possibly distinct from S. permirus, when it shall 
have been further examined. This makes it, unfortu- 
nately, necessary to adopt Schaufuss’ name for the 
subfamily, a name which begs the whole question of 
their affinities. If my genera remain good, it would be 
better to change the family name to T'entocerini. 
The insects do not present any one striking feature, 
such as the upturned abdomen in Scolytus, or the 
elongate first tarsal joint of Platypi, and must be 
recognised by a combination of characters.
