50 [August. 



Antennae stout, club broad, three-jointed, 9th and 10th joints transverse, termi- 

 nal not longer than broad. Head transversely sub-quadrate. Thorax rather short 

 and broad, its greatest width very near the front, much narrowed behind, almost 

 impunetate, the basal fovete very obsolete, placed one near the outer angle and one 

 just outside it. Elytra unusually short and broad, with well-marked pubescence 

 and only a feeble punctuation. 



This is intermediate between the ordinary Eumicri and the pe- 

 culiar species forming the next group : the mesosternum is only feebly 

 carinate, but the middle coxae are not more distant than usual. 



lehinchi and Hitoyoshi, commencement of May, 1881 ; two 

 examples. 



B. Middle coxse more largely separated, mesosternum ecarinate. 



4. EUMICRUS CRIBEATUS, Sp. 17. 



Sat convexus, suhtiliter puhescens, pallide rufus ; protJiorace elongato, posterius 

 angustato,fere impunctato ; elytris crehrefortiter punctatis. Long. \\ mm. 



Antennae rather small, club slender, three-jointed, 8th joint very small. Head 

 transversely quadrate, not punctate. Thorax longer than broad, its greatest width 

 much in front of the middle, strongly narrowed towards the front and much nar- 

 rowed behind, without impressions. Elytra rather coarsely and closely punctate. 



Allied to E. reversus, but readily distinguished by the nearly im- 

 punetate thorax. 



Napporo, Kashiwagi, June 15th, 1881 ; five examples. 



5. EUMICRUS EEVEKSUS.

Mr. Lewis has now found a small series of this remarkable little 

 insect ; the peculiar pygidial structure described by me (I. c.) proves 

 to be peculiar to the male sex, the pygidium in the female being 

 normal. The structural characters previously given by me are mostly 

 such as are now recognised as characteristic of Eumicrus, the meso- 

 sternal structure is, however, not that normal in the genus mentioned, 

 but it would be superfluous to institute a new genus on this account 

 at present. 



Found in thatch at Ipongi, March 31st, 1881 ; at present only 

 taken in the Nagasaki district.

 ahrupta, triarticulata. Long. \^ mm. 



Joints 3 — 7 of the antennae are small, the 8tli very evidently larger, the club is
