296 Mr. D. Sharp's revision of the 



Ctenistes discedens, n. s. 



$ . Testaceus, crebrius pallido-setulosus, antennis 

 elongatis, articulis 9o et lOo praecedentibus parum 

 longioribus, articulo terminali sat elongato ; capite brevi, 

 oculis magnis ; prothorace brevi, setuloso sed baud 

 sculpturato, elytris hoc duplo longioribus ; pedibus elon- 

 gatis tenuibus. Long. 2 mm. 



This is another very aberrant Ctenistes quite dissimilar 

 from any other known to me, and cannot be associated 

 with the species of either of the two subgenera proposed 

 by Eeitter, nor with any North American species known 

 to me. The antennae are nearly 1|- mm., the 3rd joint 

 rather longer than the 2nd, it and joints 4 — 8 scarcely 

 differing from one another, each longer than broad ; 9th 

 and 10th subequal, each longer (but not greatly so) than 

 the 8th ; 11th joint about equal in length to them 

 together. Head short and broad, with very large eyes. 

 Thorax slightly transverse. Three first dorsal segments 

 about equal to one another. Hind trochanters mode- 

 rately long, stout, not clavate. 



The individual described is no doubt a male ; it has 

 the anterior trochanters and the base of the femora 

 armed beneath with erect setae, the metasternum deeply 

 and broadly impressed along the middle, and the ventral 

 segments somewhat depressed on the middle for the 

 greater part of the length of the hind body. 



Hitoyoshi, 8th May, 1881. 



A specimen found at Kioto on the 10th June, 1881, is 

 probably the female of this species ; it has the same 

 setulosity on the front legs, and the trochanters corre- 

 spond, except that those of the middle and hind legs are 

 rather shorter ; the antennae are different, being much 

 shorter ; joints 3 — 10 slender, each longer than broad ; 

 10th about equal in length to the 3rd, but a little 

 stouter ; terminal joint rather stouter, as long as the 

 three preceding together ; metasternum less impressed ; 

 ventral segments not impressed. 



Ctenistes breviceps, n. s. 



Flavo-castaneus, elytris rufescentibus, crebrius, sub- 

 tiliter flavo-setulosus, palpis testaceis articulis ultimis 

 extus parum prolongatis ; capite brevi, lato ; prothorace
