On some Plataspine and Graphosomine. 233 
XXXI.—Notes and Descriptions relating to some Plataspins 
and Graphosominz (Rhynchota). By W. L. DISTANT. 
THE British Museum having recently acquired the very fine 
and extensive collection of Plataspines amassed and studied 
by Dr. A. L. Montandon, it has become possible— particularly 
in so vast a genus as Coptosoma—not only to identify many 
obscure species but to describe some new ones. It has 
naturally also become necessary to add a few synonymical 
notes. 
A study of the Graphosomine, the result of some recently 
arrived material from the Oriental region, has also added to the 
described species and genera. 
RHYNCHOTA. 
Fam. Pentatomide. 
Subfam. Prarasprv@. 
CODRONCHUS, gen. nov. 
Somewhat broad and moderately convex. Head large, 
angulate, the central lobe very broad and ovate, a little shorter 
than the lateral lobes, which are divergent and do not meet in 
front, lateral margins moderately concave from base to about 
the region of the insertion of the antenne and then oblique and 
reflexed to apex ; eyes prominent, ocelli nearer to each other 
than to the eyes; pronotum with the lateral margins convex, 
the anterior margin much excavated, nearly straight at the 
extreme base of head, the disk prominently transversely 
impressed ; scutellum broad, not quite reaching the apex of 
the abdomen, its apex slightly concave; stigmata near the 
abdominal margin ; rostrum reaching the intermediate coxe ; 
antenne five-jointed ; a raised centrally hollowed and mar- 
ginally ridged process between the intermediate and posterior 
COXR. 
Allied to Cratoplatys and Heterocrates. 
Codronchus andamanensis, sp. n. 
Black, very thickly punctate; eyes ochraceous; rostrum 
brownish ochraceous ; femora more or less castaneous. Head 
with an undulating transverse ridge between the eyes and 
with a short waved basal ridge; pronotum with a patcn ur 
transverse striz at centre of anterior margin, and with a
