80 Mr. Walter F. H. Blandford on the 
transverso, fortiter punctato, punctis ovatis in medio disco magis 
discretis, subtilioribus ; elytris prothorace dimidio longioribus, 
lateribus subrotundatis, postice angustatis, margine apicali sub- 
truncato, fortiter lineato-punctatis et substriatis, interstitiis 
angustis uniseriatim punctatis, punctis vix subtilioribus, seriebus 
nonnunquam irregulariter impressis ; abdomine convexo, mutico, 
piloso. Long. 5 mm. 
Mas. (?). Abdominis segmento 5o pilis longis ornato. 
Fem. (?), Abdominis segmento 50 breviter piloso. 
Junsai, two specimens. 
Allied to S. carpini, Ratz., but with stronger thoracic punctua- 
tion, and elytral striz more impressed with coarser punctures. 
Black with elytra pitchy-brown. Head convex, finely aciculate 
and glabrous, without sexual differences; vertex dull, closely punc- 
tured. Prothorax as long as broad, with strong oval punctures, 
scattered on disc, closer, deeper and rugose at sides and apex. 
Elytra as wide as thorax and one-half longer, with lateral 
margins slightly rounded to behind middle, then narrowed ; apical 
margin nearly truncate, feebly excised at suture, and slightly 
irregular, but not serrate as in S. agnatus ; surface with regular 
rows of strong punctures, deeper and closer at base, slightly 
impressed throughout, interstices narrow, with a single series of 
punctures rather weaker than those of strive, and sometimes im- 
pressed, first and second with a few oblique wrinkles. Abdomen 
convex, covered with short hairs; last segment in male (?) emar- 
ginate at apex and impressed, with a fringe of long hairs. 
Smaller than any other Japanese species except 
S. japonicus, which is readily distinguished by its black 
colour, and the absence of striate impressions on the 
elytra, the punctures of which are fine and obscured by 
oblique wrinkles.

Chap., Scol. Jap., p. 199. 
A single further specimen of this species, the repre- 
sentative of the European S. rugulosus, taken at Junsai. 
It attacks the plum-tree. 
Scolytus claviger, sp. n. 
Subelongatus, depressus, niger, elytris piceis, antennis pedi- 
busque rufescentibus ; prothoracis disco parce punctato, punctis 
versus basim subtilioribus ; elytris regulariter striato-punctatis,
