carina in its centre; the scutellum is small, clotlied with 

 golden-grey pubescence and distinctly elevated ; the elytra 

 are densely and roughly punctate, marked with small patches 

 of brownish setee ; on either side of the scutellum the basal 

 edges of the elytra are a little ])rojecting, and behind the 

 scutellum, but well away from the suture, are two short 

 polished carinje, apices blunt. 



Hab, Kawatchi. 



The two curious elytral carina distinguish this species 

 from most, if not all, of the described species of Apate ; but 

 Mr. Gorham has a species from the Andaman Islands which 

 closely resembles it. Its chief differences are, the antennae 

 are shorter and stouter, the thorax parallel at the sides, 

 rectangular at the base, the scutellum not elevated, and the 

 two elytral carina? are half as long again ; both species 

 measure L. 13 mill. In the Andaman species the tarsi are 

 also shorter and the terminal joint of the antenna is conical. 

 In A. carinipennis the terminal joint is distinctly oval"^. 



Apate niponensis, sp. n. 



Elougata, parallela, nigra, nitida : capite rugoso, in medio obscure 

 laevi ; thorace dense imbricato-rugoso ; scutello elevato ; elytris 

 profunda seriatim punctatis, ante apicem valde bituberculatis. 



L. 15 mill. 



Elongate, parallel, black, shining ; the head rugose, with 

 a small smooth median space between the eyes which is 

 connected with the base of the head by an ill-defined polished 

 line; the thoi'ax rugosely sculptured, the rugosities assume 

 an imbricate form, especially on the disk ; the anterior 

 thoracic processes are bent downwards towards the head, are 

 hamate at the tips, and are based on two tuberculate ridges, 

 the outer row of tubercles being the strongest ; the small 

 scutellum is distinctly elevated ; the elytra are deeply punc- 

 tate, the punctures are set in somewhat irregular rows, the 

 sutural margin is elevated, and there are two median rather 

 vague costse separated from each other by three rows of 

 punctures, and well before the apices at an equidistance from 

 the suture and outer edge are two large tubercles, one on each 

 elytron, they are polished and bent towards each other; the 

 apical rim of the elytra is elevated rather more strongly than 

 the sutural margin ; the antennae and thighs are piceous.

* Mr. Gorham wishes me to name his insect; I propose, therefore, to 

 call it Apate cariiiata, sp. n.
