Found sparingly in several localities ; Tokoliama, Niigata, Naga- 

 saki, in spring and autumn. 



2. EUCONNUS DTILCIS, Sp. 11. 



3Iimts convexus, rttfescens, ttitidtis ; antennis suh-gracilihus clava qiiadriarticu- 



lata ; capite utrinqtie dense Iiirsuto ; thorace suh-quadrato, basi sulcula transversa 



utrinque foveolata ; elytris laxe pubescentihus, basin versus sub-deplanatis. 



Long, vix 1^ mm. 



Antennae with joints 3 — 6 equal, 7th larger, almost intermediate in size between 

 the 6th and 8th, so that the club is not abrupt, this consists of four sub-equal joints, 

 each about as long as broad. Palpi with quite slender pseudo-terminal joint. 

 Head broad, with a tuft of dense hairs on either side behind the eye. Thorax about 

 as broad as it is long, its pubescence rather scanty, with a well-marked fovea on each 

 side, and a finer channel between and connecting them. Elytra rather flat at the 

 base, a little distance within the shoulder with a rather deep depression, not punc- 

 tate, but with a scanty, fine, long pubescence. Tibiae very slender. Mesosternal 

 lamina very erect, very slender. 



Nagasaki ; four examples. 



3. EUCONNTJS DEBILIS. 



Scijdmcenns dehiJis, Sharp, Tr. Ent. Soc. Lend., 1874, p. 127. 

 Very distinct by the three-jointed club of the antennae. Also 

 rare ; but a single example was procured at Kioto July 4th, 1881. 



4. EUCONNUS JAPOIS'ICUS. 



Scydmcenus japonicus, Sharp, 1. c, p. 127. 

 This is also a Euconnus, though peculiar, owing to the small head 

 and the comparatively large eyes ; taking, however, the structure of 

 the anterior part of the head and the insertion of the antennae as the 

 criterion of the genus, and not the distance of the eyes from the 

 neck, there can be no doubt of the systematic position of the insect. 

 It has not been met with since Mr. Lewis' first visit. 



5. EuCONNUS FUSTIGER. 



Scydmcenus fusfiger, Sharp, I. c, p. 128. 

 This, too, is a Euconnus, allied to the following ; it is apparently 

 rare, as it has been met with near Nagasaki in the spring on three 

 occasions, each time in a single example. 



6. EucONNUS LeWISII, sp. 11. 



Angustulus, breviter, dense pubescens, fusco-7-iifus, elytris magis rujescentibus, 

 antennis pedibusque testaceis, illis clava breve perabrupta, quadriarticulata ; pro- 

 thorace conico, hand impresso. Long. \\ mm. 



Antennse short, with remarkably abrupt, broad, four-jointed club, each articula- 

 tion of wliich is transverse. Palpi with rather broad and short pseudo-terminal 

 joint. Head narrow and elongate, very densely pubescent, vertex much prolonged.
