12 Mr. David Sharp on the 



Antennse reddish, fourth joint longer than broad, tenth 

 scarcely so long as broad. Head reddish, as broad as the 

 thorax, truncate behind, closely and distinctly punctured, 

 impressed in front. Thorax much narrower than the 

 elytra, rather broader than long, foveolated at the middle 

 in front of the base, and with a fine central channel vari- 

 able in distinctness, its sculpture similar to that of the 

 head. Elytra distinctly longer than the thorax, rather 

 shining reddish ; they are rather coarsely and closely punc- 

 tured, the suture a little impressed behind the scutellum. 

 Segments 2-5 of the hind body are strongly impressed at 

 the base, the 5th less so than the others ; the impressions 

 rugose, elsewhere finely but not closely punctured, but 

 distinctly pubescent. The legs reddish. 

 Seaweed. 



22. Tacliyusa algarum, n. sp. Rufescens, abdomine 

 apicem versus obscuriore ; capite, prothorace elytrisque 

 dense, abdomine parce, punctatis ; antennis articulo 4° 

 subquadrato. Long. 1 lin. 



Closely allied to the preceding species, but much 

 smaller, and with the antennfe considerably shorter, the 

 4th joint thereof being scarcely so long as broad ; the 

 sculpture of the front parts of the body is scarcely so 

 distinct as in T. rufescens, but in other respects the two 

 species are very similar. 



Under seaweed, in company with T. rufescens. 



23. Oxypoda japonica, n. sp. Nigro-fusca, antennarum 

 basi piceo-testaceo, pedibus elytrisque testaceis, his circa 

 scutellum margineque laterali infiiscato, prothorace lateri- 

 bus, abdominisque segmentorum marginibus obscure tes- 

 taceis. Long, If — 2 lin. 



AUied to O. luteipennis, but at once distinguished by 

 its much shorter antennas. These have the basal joints 

 obscurely yellomsh, the 3rd joint a little longer than 2nd, 

 4 — 6 differing little from one another, each about as long as 

 broad, 8 — 10 slightly transverse, 1 1 th pointed, about as long 

 as the two preceding. Thorax distinctly narrowed in 

 front, finely punctured, the sides broadly yelloAvish, the 

 base a little sinuate on each side close to the hind angles, 

 so that these are nearly right angles. Elytra coloured 

 and punctured as in A. lateipemiis, deeply sinuate at the 

 outer angle. Hind body pointed behind, very densely
