442 Mr. Blandford on the Scolyto-platypini. 
counterpart in Pterocyclon, and even the triangular 
tarsal joints of S. tycon are repeated in Platydactylus. 
The 6-jointed funiculus is not found in any known 
wood-boring Tomicid, though it occurs in others; but 
this part is very variable, and always a reduction from a 
7-jointed structure. The solid Platypus-like club is not 
rare in Tomici, e.g., T'rypodendron ; its reticulation may 
serve as a guide to their relationship, but at present 
I know nothing quite like it. In S. mikado, 3, it is less 
evident, owing to the smaller size of the pits, a further 
reduction in which would bring the antennal surface to a 
condition resembling that of Crossotarsus wallacei, the 
largest Platypid. 
I cannot indicate more than a general relationship 
with the Tomicini. The smallest species, S. siomio, 2, 
has, if we disregard the thorax, a certain likeness to 
Trypodendron. 
Mr. Lewis informs me that S. mikado, which appears 
to be the commonest and most widely distributed of the 
Japanese species, aS well as the most striking, was 
usually taken in May on the twigs of plum-bushes in 
blossom, from which it was beaten.
