9 (8) Thorax sliglitly Irausverse; eyes in S

of nearest approach : species more », - ,,

10. (5) Species piceous. (Japanese.) ^e^n^t, sp. n. 



D iestaceus, Lee, ^vas described upon a single female 

 example from Lake Superior, and I am not aware ot any 

 subsequent records ol: its occurrence. 



D lesne-^ so. n., resembles D. concolor, Newm., but is 

 pitdiy brown'in co'lour. The eyes in the J are separated 

 by a Ipace about as wide as the thickness of the second .,on t 

 of the antennae. The thorax is fully as long as broad, 

 bol St bout the mKldle, becoming slightly narrower 

 o;;ards the base, whteh is sharply .--f^-^, ^^^7; f; 

 rapidlv narrower to the apex ; the disc is nitid, clothed yth 

 a scanty pubescence, with a slight median depressum before 

 the base.' The eh trL are subparallel, with the lateral margins 

 visd)lefrom above for the posterior tl^'-ee-q"^^rters ot t ui 

 ]en<nh; they are moderately nitid, puncta e, with a tlim 

 pubescence id slight indications of longitudinal furrows as 

 in D. ephemeroides.

/i"^ Japan, Yun.o to near Chuzenji, and to near Nikko 

 Au" i'ioJ [k Gallois) ; environs ot Tokio (J. llarmand, 

 iml). ' Communicated by the Paris Museum. 



It is curious that a species of this genus should at last have 

 been discovered m Japan, since the two Japanese spec.es 

 ascribed to it by Mr. Lewis belong to a distinct genus 

 {Psmdodendroides, gen. nov.). 



PsEUDODENUB,OIDES, gCU. UOV. 



Differs from Dendroides, Latr., in the less parallel, more 

 depressed form, in tbe denser puncturatiou and P;^'^;;^;;^'>^^^^^ 

 the elytra and in the much stouter antenme, ot which the 

 u . sm the S are not exeeplioually long and slender.
