90 Mr. Walter I’. H. Blandford on the 
curvatis articulo 1o ovali, ceteris lunatis. Prosternum processu nullo. 
Episterna metathoracica linearia. Tibiee anticee ad apicem dilatate, 
spinose. Corpus cylindricum, elytris ad apicem retusis, ambitu 
retusionis fortiter multi-spinato, stria suturali vix impressa. 
Ciosely allied to Tonicus but differing in the much 
stronger elytral armature, which in Yomicus exhibits a 
uniformly progressive diminution, as the species grow 
smaller, down to the genus or subgenus Pityogenes, 
Bedel. The antennal club is oval, its sutures are quite 
superficial and only marked by a pubescent border, the 
first jot is longitudinally oval and embraced at the sides 
by the succeeding joint, as in \ylocleptes, Ferrari, with 
which the elytral structure has no affinity. The mouth 
parts do not differ from these of Vomicus, the maxilla is 
simply sinuate internally, and not produced into a 
rounded angle, but this angle is wanting in Pityogenes 
and is not a generic character. 
Acanthotomicus spinosus, sp. n. 
Oblongus, cylindricus, nitidus, ferrugineo-testaceus, elytris ad 
apicem infuscatis, pilis longis parce adspersus ; prothorace antice 
constricto, ad medium subgibboso et utrinque impresso, anterius 
exasperato, posterius subtiliter punctulato; elytris prothorace 
dimidio longioribus, punctato-striatis, punctis ad basin subtilibus, 
versus apicem dilatatis, ad apicem abrupte declivibus, utrinque 
8-spinatis, spinula 3a maxima, elongata, 5a—Va minimis, 8a prope 
angulum suturalem magna, intus curvata. Long. 2°5 mm. 
Two specimens taken at Oyayama and Nikko. 
Oblong, cylindrical, reddish-testaceous, with apex of elytra in- 
fuscate. Head with front subconvex, punctured, with a median 
raised line, thinly pubescent ; eyes broad oval, slightly emarginate. 
Prothorax longer than broad, its base truncate, basal angles obtuse, 
sides almost parallel to middle, then constricted and strongly 
rounded to apex, which is somewhat more obtuse, with a crenate 
margin; disc gibbous in middle and impressed on either side, 
asperate anteriorly behind with fine scattered punctures without a 
median impunctate or elevated line. Scutellum small, rounded, 
elytra half as long again as prothorax, their base truncate, 
sides subparallel, with lines of punctures, fine at base, becoming 
stronger, dilated and transversely rugose towards apex, the strix 
appearing impressed towards apex in a certain light only, interstices
