Rhynchophorous Coleoptera of Japan. 91 
slightly convex, very finely and sparingly punctured in rows ; apex 
nearly vertically declivous, margined with 16 spines at the apex of 
the 2nd and succeeding interstices, the 1st two short, 3rd very long, 
curved, 4th and 5th rather shorter, 6th and 7th small, 8th pair 
situated close to apex of suture, curved inwards and as long as 
fourth. Impressed surface rather dull, irregular, strongly punctured, 
with suture elevated. Underside testaceous, glabrous. Antenne 
and legs testaceous. 
The following specimen is probably the female of the 
preceding insect, but I cannot be positive. 
Acanthotomicus spinosus, ? femina. 
Antecedenti differt fronte plana utrinque densissime aureo- 
villosa, prothorace paullo longiore, minus constricto, margine 
antico fortius rotundato, haud crenato, dense villoso; elytris pro 
portione elongatis, prothorace duplo fere longioribus, punctis 
striarum paullo fortioribus et magis confertis, ad apicem singulatim 
breviter 6-spinosis, infra prope angulum suturalem in lobum 
brevem 4-tuberculatum productis ; fundo retusionis punctis mi- 
noribus, confertis, et spinula intra spinam tertiam marginalem 
posita utrinque ornato. Long. 3mm. 
One example taken at Kashiwagi. 
In the dense villosity of the head and prothorax, and 
the reduction in size of the apical spines of the elytra, 
its characters may be considered as simply sexual. But 
the greater length of the elytra and the closer and 
stronger punctuation of the striz, the sutural stria being 
impressed at the apex, together with the presence of a 
spine on the apical declivity internal to the 3rd marginal 
spine, prevent my identifying it positively as the female. 
The apical spines are all short, the 3rd and 5th being 
the most prominent; the lower border is produced on 
either side just outside the suture, into a short transverse 
lobe, which is evidently 4-tuberculate and represents the 
three inferior spines fused. 
Dryocatss, Hichh. 
This genus, in which I include Hichhoft’s Taphrorychus 
apatordes and two allied species, is represented by eight 
species, of which six are new.
