THE TETTIGIDiE OF CEYLON. 
131 
A series of ten specimens were taken “ from swampy ground ” 
at Pundalu-oya in March by E. Ernest Green. 
Acanthalobus , gen. nov. 
Plate II., figs. 8-8&. 
Related to Griotettix , Bolivar. Body more or less tubercalose, 
granulate or nodulose, or rugulose. Head not exserted or elevated ; 
crown short. Eyes moderately prominent. Vertex wider than 
eye flattened, subfossulate on each side, middle feebly carinate, in 
front provided on each side with arcuate abbreviate margin ; 
supra-ocular lobes at the lateral margin distinct. Frontal costa 
in profile advanced more or less before the eyes ; face lightly 
retreating. Antennae moderately short filiform, inserted between 
the lower portion of the eyes. Pronotum truncate in front, 
posteriorly extended backwards beyond the femoral knees long 
subulate or abbreviated ; dorsum above flattened, between the 
shoulders more or less convex, behind the shoulders often bifos- 
sulate ; median carina of pronotum slender scarcely elevated, 
sometimes interrupted ; lateral carinse posteriorly on the apical 
process often obsolete ; posterior angle of lateral lobes laminate 
produced outwards, armed with an oblique spine. Elytra oblong- 
ovate ; wings extended to or beyond the pronotal apex. Maxillary' 
palpi elongate, very slightly compresso-ampliate. Femoral 
margins entire or lightly crenulate, the second femora rarely 
indistinctly sublobate or denticulate. First article of posterior 
tarsi little longer than the third. 
Griotettix , Bolivar, in part. 
Resembling Griotettix but differing from that genus in having 
larger stature ; in the structure of the vertex ; in the eyes being 
less globose and not at all exserted ; the pronotum being broader 
between the shoulders ; the absence or but slight evidence 
of a short supernumerary carinula on each side between the 
shoulders and also in the more pronounced rugose surface of the 
dorsum. 
This genus embraces such species as A. flavipictus , Bol. ; A. 
miliarius, Bol.; A. bispinosus, Dalm.; A. saginatus, Bol. ; A. m. 
cuneatus , Hanc., &c. 
Key to Species of Acanthalobus.

the knees of hind femora. (Plate II., figs. 8-8a), miliarius ,
