104 Mr. Walter F; H. Blandford on the 
two shining lateral impressions, with thin pubescence at sides and 
a dense patch before scutellum, which is large, shining, and 
rounded, Elytra as wide but not as long as prothorax, basal 
borders feebly convex, shoulders narrowly elevated; at first 
cylindrical, then obliquely declivous from basal fourth to apex, 
shining and irregularly punctured, the punctures rugose and con- 
fluent along basal margin ; apical declivity rounded oval with a 
sharp raised margin to sides and lower border, its surface subconvex, 
pilose, with impunctate striz, interstices closely granulate ; lateral 
border of elytra declivous, parallel throughout to margin of apical 
declivity. Underside black, thinly pubescent, anterior coxe 
separated by a narrow prosternal process. Legs ferruginous, 
tibie strongly dilated and obsoletely spined; tarsi short, their first 
three joints compressed, and pilose beneath. 
The most extreme type of the truncate Xylebori I have 
seen, and a remarkable instance of the diversity of form 
which the genus presents.

Four examples, Nikko; originally taken at Hagi by 
Hiller. Identified by the description. 
Xyleborus lewisi, sp. n. 
Fem. Oblonga, cylindrico-convexa, pilosa, rubra elytris infus- 
catis ; prothorace subgloboso, apice tamen deplanato, supra sub- 
aequaliter convexo, opaco, antice fortiter postice paullo subtilius 
asperato ; elytris subnitidis, striato-punctatis, interstitiis subtiliter 
biseriatim punctatis in declivitate tuberculatis, apice oblique declivi 
ad suturam impresso. Long. 4°5 mm. 
Nikko, Hakone, Miyanoshita, nine specimens. 
Oblong, convex, and cylindrical, pilose with long hairs, red with 
elytra infuscate. Head coarsely and rugosely punctured, with an 
indistinct elevated median line, thinly hairy and ciliate over 
mouth. Prothorax transverse, nearly globose, but with sides and 
apex separately rounded and antero-lateral angles more strongly 
rounded, base subsinuate with obtusely rounded angles ; above gib- 
bous and convex, but without median elevation, dull and entirely 
scabrous, the asperities a little weaker posteriorly. Scutellum 
rounded, shining, infuscate, anteriorly impressed. Elytra as wide as 
base of prothorax and more than one-half longer, truncate at base,
