86 Mr. D. Sharp on some 



1st joint but little different from tlie following ones, being 

 only slightly longer and thicker than the 2nd ; joints 2 — 8 

 differing but little from one another, each about as long 

 as broad; joints 9 — 11 distinctly larger than the pi'eceding 

 ones, not transverse, the 11th rather the largest. Head 

 coarsely punctured, not broad, a little narrower than the 

 thorax. Thorax a good deal narrower than the elytra, 

 nearly as long as broad, distinctly narrowed behind, the 

 sides crenulate, it is coarsely punctured, and finely and 

 indistinctly pubescent. Elytra rather slender, with rows 

 of coarse punctures, and with a fine but rather elongate 

 pubescence. 



Found rarely in decaying vegetable matter on the 

 mountains of Oahu ; sent as No. 204. 



I have seen but a single individual of this species ; it 

 cannot be placed in any established genus, and as its 

 position is certain, I have given it a new generic name. 

 Its structure is similar to that oi Psamm(Bchus, but the 

 basal joint of the antennge is less developed, and the apical 

 joint of the maxillary palpi is not dilated, but acuminate. 

 The tarsi have the 2nd and 3rd joints strongly lobed 

 beneath, and the 4th joint small. The position of the 

 genus at present is clearly therefore hetween Psammcechus 

 and Telephanus. In appearance the species may be de- 

 scribed as intermediate between Silvanus and Corticaria.

Antilissus (new name). 



Antilissus aper, n. sp. Elongatus, angustulus, paral- 

 lelus, subcylindricus, fusco-ferrugineus, opacus, parcius 

 hispidus ; prothorace elongato, sulculis angustis, profun- 

 dis, connexis, ornato ; elytris punctato-sulcatis, intersti- 

 tiis angustis ; antennis pedibusque ferrugineis. Long. 

 3 — 4 mm. ; lat. 1 mm. 



Upper surface of head parabolic in form, the eyes con- 

 tinuing the outline of the sides, the posterior part bearing 

 very flat tubercles, the anterior part very indefinitely 

 sculptured. Thorax elongate and narrow, considerably 

 longer than broad, nearly straight at the sides, the front 

 margin with a rather deep, narrow sinuation on each side, 

 so that the anterior angles are prominent ; the surface is 

 covered with flat tubercles, and peculiar depressions ; the
