406 Rev. H. S. Gorham's revision of the 



Plateros purpurivestis, n. s. 



Niger, prothorace brevi, angulis posticis acutis, disco 

 nitido baud canaliculate- vel carinato, insequali ; elytris 

 squamulis purpureis dense vestitis. Antennis serratis. 

 Long. 6 mm.

As there is but a single specimen of this it will be 

 better to merely indicate it here than to give a longer 

 description. The elytra, which appear of a rich brown 

 hue from the scales which clothe them, will sufficiently 

 distinguish it in its genus. 



Plateros ? nothus. 

 Eros nothus, Kiesenw., Berl. Ent. Zeits., 1874, p. 258.

I should not like to make a genus for this insect 

 without further acquaintance with the types of some 

 other Eastern Platerotes and Calochromi, described by 

 Mr. Waterhouse, but which, owing to the removal of the 

 collections of the British Museum, I am unable to make 

 at present. It combines certain characters of both 

 genera, having a rude obsolete channel on the disk of 

 the thorax, with a short oblique ridge starting from a 

 little above the hind angles on each side of the thorax. 

 The antennae also are unlike those of Plateros, having a 

 distinct bead-shaped second joint, and those following 

 not compressed nor serrate, but pubescent ; all these 

 characters indicating a type but little developed, and 

 highly synthetic. 



Seven specimens were taken by Mr. Lewis in 1881. 



Plateros ? lineatus, n. s. 



Nigro-fuscus, prothorace brevi disco carinato et per 

 carinulam transversam sinuatam in areolas quatuor 

 diviso, elytris quadricostatis, intervallis serie duplici 

 punctorum, costis (prsesertim externis) et ad basin brun- 

 neis, squamosis. Long. 6£ — 7 mm. 



Kashiwagi. 



This is again a form unknown to me, but for which I 

 do not at present think it well to institute a genus. Of
