140 Mr. Walter F. H. Blandford on the 
Rather slender and very shining, head and prothorax deep 
piceous, the latter with basal border narrowly fusco-testaceous, 
elytra fusco-testaceous at base, becoming pitchy towards apex. 
Head with front nearly flat, impressed slightly over mouth, dull, 
with rather distinct and strigose punctuation below, the punctures 
less apparent towards vertex, in the middle with a short median 
elevated keel, which is not perceptible towards vertex ; elevated 
lines of the latter very evident and shining. Prothorax very 
shining, rather deeply emarginate at sides, apex with a row of 
piliferous punctures, rest of surface quite impunctate, except at 
base which is closely and strongly punctured. Elytra with first 
two strize and marginal stria impressed throughout, third and 
fourth at base only, outer striz indicated by lines of irregular 
punctures, which coalesce towards apex, interspaces almost im- 
punctate ; 1st interstice with a minute spine at apex, 3rd and 5th 
with two long spines, 7th with a shorter spine, the outer border 
of which is conjoined with two serrations formed by the ex- 
tremities of the succeeding interstices, external angle with a very 
slender spine directed obliquely downwards, apex fringed with a 
few long ciliate hairs, apical impression oblique, subconvex, with 
two spines shorter than the three long spines of the interstices. 
Underside testaceous, metasternum and abdomen piceous, last seg- 
ment of the latter nearly flat, dull, fringed with long curled cilia. 
This species is closely allied to D. quinque-spinatus, 
Chap., of which it may be the Japanese form. It 
presents the following distinctive features: the colour is 
deeper and the surface more shining, the frontal carina 
is shorter, nearer the mouth, and not traceable towards 
the vertex as in D. quinque-spinatus, in which it appears 
to be longer and interrupted; the prothorax is quite 
impunctate except at the apex and base, and the basal 
punctures are more numerous; the interstices of the 
elytra are scarcely punctured, the spine of the 7th 
interstice is shorter and that of the 9th only represented 
by a small tooth, the spine at the external apical angle 
is pecuhar to this species, as is the terminal fringe of 
hairs; the spines of the posterior depression are also 
shorter.
