70 ME. DAVID SHAEP ON 



Nara, end of June; Suwa temple, Nagasaki, 17th April. 

 Three examples. 



Teionijs, nov. gen. 



Corpus depressuni, sculpturatum. Antennae basi tecta, 11 -articulatae, 

 clava biarticulata ; sulci antennarii elongati. Coxae valde approximatse, 

 tibiae lineares, ecalcaratae ; tarsi articulis tribus basalibus parvis. Abdo- 

 minis segmento ventrali basali brevi. Ex affinitate generis Bitomce, sed 

 sulcis antennariis elongatis. 



On the underside of the head the eye appears rather large, 

 and along its inside margin there is a slender antennal furrow, 

 which extends backwards beyond the eye, curving behind it, 

 where a small fossa is found for the base of the club, the other 

 side of the club reposing on the front margin of the prosternum. 

 All the coxae are more than usually approximate, and the first 

 ventral plate is but little longer than that following it. 



Although similar in appearance to Bitoma, this insect cannot 

 be placed in it on account of the antennal grooves, as described 

 above. I have a second species, closely allied to Trionus opacus, 

 in my collection from East India. 



Teiontis opacus, n. sp. 



Rufescens, elytris fuscis ; opacus, depressus, rude sculpturatus ; protho- 

 race elytrisque costatis. Long. 2J-3 millim. 



Antennae short, the ninth joint quite small. Head with 

 raised rough granules. Thorax transverse, straight at the sides, 

 and with the front angles a little prominent ; the surface rough, 

 and with some fine raised irregular ribs ; the middle pair pos- 

 sessing some abbreviated pieces at the base connected with it, 

 and being near the front abruptly constricted ; the outer pair 

 more regular, but slightly sinuate, and towards the front curving 

 inwards ; the side of the thorax is directed outwards, and is in- 

 distinctly crenate, without raised margin. The elytra have each 

 three very strongly elevated fine ribs, and between them are 

 transversely reticulate, the reticulations being the fine interstices 

 of large punctures. Underside of head granular ; ventral plates 

 transversely impressed. 



Nagasaki, Ichiuchi, and Tumamoto ; eight examples. 



XUTHIA PAEALLELA, n. Sp. 



Fusca, opaca, antennis pedibusque rufis; prothovace oblongo, argute 

 quadricostato; elytris fortiter punctatis subtiliter costatis. Long. 3^ 

 millim.
