20 COLEOPTERA CHLAMYDAE. 



abruptly narrowed in the middle third and compressed to a thin line 

 in the rear third ; length 3 mm. 



Type. — 9; from Yunnan ; three 9 examples. 



Front thickly, finely punctate, vertex slightly longitudin- 

 ally depressed, antenna short and stout, the 2d joint stout 

 trigonate, 3d and 4th equal and cylindrical, the remaining 

 transverse and forming a moderately compact club, thorax 

 thickly punctured, coarsely at sides, gibbosity, strongly 

 rounded, almost perpendicular in front and behind, basal 

 sulcus obsolete, the median sulcus moderately wide and 

 marked with parallel ridges or carinae, which nearly attain 

 both base and apex, of the two lateral carinae on the gib- 

 bosity, the external is short and broken and forms the upper 

 edge of the rear declivity. The internal leaves the median 

 carina at the apex of the gibbosity, swings out in a short 

 curve and descends towards the anterior edge in a line diverg- 

 ing from the median, elytra moderately strongly punctate, 

 the usual lines very faint, appearing to be broken into short 

 pieces and tubercles, none being particularly prominent, a 

 line of about five tubercles shows parallel to the suture, the 

 first basal, the last apical semi-costiform, below coarsely 

 punctate, the sides of the abdomen with a large and small 

 tubercle, the latter at the rear. 



Chlamys setosa nov. sp. Black, slightly bronzed, thorax rather 

 thickly, elytra very sparsely clothed with very fine yellow setae, form 

 robust quadrate, slighty narrowed behind ; antennae, labrum and legs 

 dilute brown gradually shading into blackish ; length 4 mm. 



Type. — c? ; Yunnan. 



Head rugosely and coarsely punctured, vertex with a well 

 defined sulcus, antennae long and slender, 2d joint globular, 

 3d very shortly trigonate, the remaining joints transverse 

 and loosely articulated, thorax rough with small humps and 

 lines, and finely punctured, obsoletely strigose in places, the 

 setae giving the surface a yellowish look, especially at the 

 anterior sides, the middle occupied by a well developed hump 

 which is sharply declivous behind and limited at the sides by 

 the usual side groove, the median sulcus starts from the rear 

 edge, narrow, deep and parallel, attaining the top of the rear
