and on some Types of Oriental Carabidae. 181 
mandibles (4) moderately dilated and bordered outwardly, a slight 
longitudinal prominence on middle of upper surface. Prothorax 
(5-5 mm, wide) cyathiform, side furrows deep, median line fairly 
deep and crenulate, surface almost impunctate, except along base 
and front margin. There is no stridulatory apparatus, which 
seems to be confined to certain N. African species. Hlytra not 
quite twice as long as wide, shoulders well-marked, surface smooth, 
except for a few mingled large and small punctures at base and on 
shoulders (a few very small and inconspicuous punctures are visible 
here and there on disk). 
The species 1s much like S. atrata Dej., but easily recog- 
nised by its smooth elytra. ‘The eyes are more prominent, 
the side ridges of head are entire—not half-interrupted, 
as in S. atrata; the median line and side furrows of the 
prothorax are deeper on the disk, and the elytra are a little 
longer. 
In addition to the specimens recorded by Bates (I.c. supra) 
from Rangoon and Tikekee, some of which (including the 
type) are in my collection, [ have examples from Thar- 
rawaddy and Paungde (G. Q. Corbett). In the British 
Museum there are examples from Pegu (Atkinson) and 
Rangoon, and in the Indian Museum also from Pegu and 
Rangoon (Armstrong). In the Hope Dept. at Oxford 
is a single specimen labelled “Ch.” M. René Oberthiir 
kindly gave me an example from Theinzeik, other specimens 
from the same locality being in his collection. 
The species seems to be confined to Burma, whereas all 
the examples of S. atrata De}. which I have seen come from 
Central and N.E. India.

Gen. 1892, 285. 
Piceous black: apex of elytra, metasternum, ventral surface, 
and tarsi dull red; hind trochanters light red. 
Head (2:75 mm. wide) flat on vertex, side ridges uninterrupted, 
reaching mid-eye level, a shallow groove on their inner side, neck 
strongly constricted, surface moderately and uniformly punctate, 
with a small smooth patch on vertex, mandibles slightly dilated 
and bordered outwardly. Prothorax (3-25 mm. wide) short, sharply 
contracted behind, very little in front, median line very fine, the 
adjacent area longitudinally depressed, side grooves not very deep 
(for the genus), almost interrupted on disk, surface moderately and
