devoid of 'any ridges or tubercles. If the elytra are looked at 

 sideways an obscure oblique ridge is seen from the shoulders 

 towards the suture, another somewhat transverse tubercle is placed 

 at the sides in a line with the transverse tubercle at middle. 



472. Chlamys tenebrosa, sp. n. 



Black ; basal joints of antennae and labrum fulvous. 



Head rugose ; eyes not very deeply triangularly notched ; 

 antennae with basal four joints fulvous, basal joint black above, 

 fifth and following joints transverse. Thorax with posterior 

 portion highly triangularly raised, top of elevation with two 

 rather feeble ridges that run parallel towards the anterior margin ; 

 sides of thorax with slightly raised callosities, interstices very 

 finely and closely punctured. Scutellum stronglv transverse, 

 strongly pointed at the angles. Elytra subquadrate, narrowed 

 posteriorly, an oblique ridge from shoulders to middle of suture, 

 raised into three tubercles at base, middle and apex, branching 

 from this is another high short ridge towards apex near suture ; 

 three tubercles near apex and one at middle of basal margin on 

 each elytron ; interstices more strongly punctured than those of 

 the thorax; suture serrate throughout. Pygidium strongly carinate 

 at middle, deeply depressed at sides. Body beneath closely reti- 

 culate ; legs and tarsi black.

The thorax is strongly narrowed anteriorly. The insect has to 

 be viewed sideways and turned about to see the real shape and 

 position of the elevations and ridges. 



473. Chlamys semibmnnea, sp. n. 



Piceous, with flavous tubercles and ridges ; legs dark fulvous, 

 stained with flavous, tarsi flavous ; beneath partly black. 



Elongately subquadrate. Head piceous, 

 finely rugosely punctured throughout, the 

 vertex with two small fulvous spots ; clypeus 

 an( * ^ a ^ rum f u l vous 5 basal joint of antennae 

 flavous, rest piceous, terminal five joints

 round, third and fourth slender, equal, more 

 elongate than the fifth. Thorax with middle 

 portion strongly raised, forming two ridges
