486 Mr. Blandford on the Scolyto-platypini, 
Scolyto-platypus siomio, Ni. sp. 
Antecedenti simillimus et forsan varietas. Differt elytris ferru- 
gineo-testaceis, pro portione brevioribus, tuberculis in declivitate 
fere obsoletis. Long. 8 mm. 
Mas. Prothorace antice in medio obsolete impresso; inter- 
stitiis elytrorum in versura elevatis, spinosis, vix carinatis. 
Hab. Japan, Nikko, Sendai. 
Differing from S. daimio in very slight characters, which in the 
series collected appear to be constant. Somewhat shorter, and 
comparatively broad. Prothorax in the male with anterior de- 
pression feeble and nearly obsolete. Elytra ferrugino-testaceous, 
darker along suture, relatively shorter than in S. daimio, with 
sides less parallel, and apex more vertically declivous, their basal 
border hardly visibly raised, less distinct than in S. daimio; 
declivity with strie finer, and tubercles, except last tubercle of 
sutural interstice, nearly obsolete; carine in the male less promi- 
nent. Under side similar, but lighter. 
As examples of the two species were caught at the 
same time and place, it is possible that this is merely 
a depauperized form of S. daimio; but the evident 
difference in shape is against that supposition, and 
they cannot be geographical varieties. The question of 
its distinctness must be settled by further specimens. 
There is no non-comparative character, except colour, 
by which to separate the two species. The females of 
either can be separated from those of S. tycon by the com- 
plete absence of all striz on the dise of the elytra. In 
S. stomio a sutural row of punctures is evident, chiefly 
owing to their darker colour, and it cannot be made out 
on the infuscate elytra of S. daimio.

The female is most like that of S. daimio among the Japanese 
species, but is much shorter and broader ; its colour is deep black, 
and it is duller; the prothorax is nearly glabrous, and is evidently 
produced in the middle as in the following species. Its lateral 
angles terminate with a small sharp tooth, but are not produced as 
a whole. The scutellum is much larger than in any Japanese 
species. The legs are piceous, and the hinder tibiz strongly ciliate
