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 strongly 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 aud 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 semibrnnnea, 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 
and labrum fulvous ; basal joint of antennm 
flavous, rest piceous, terminal five joints 
transversely thickened, basal joint sub- 
cylindrically elongate, second small and 
round, third and fourth slender, equal, more 
elongate than the fifth. Thorax with middle 
portion strongly raised, forming two ridges 
(when viewed from the side), each of these 
with three blunt fulvous tubercles, sides 
with shorter elevations, margins likewise 
thickened ; all raised portions fulvous, anterior portion of thorax 
paler, entire surface with dark punctures. Scutellum transverse,
