SPOLIA ZEYLANICA. 
posterior angle strongly triangularly laminate produced outwards, 
acute subspiniform, posteriorly subobliquely truncate. Elytra 
oblong ; wings explicate. Anterior femora slender entire ; middle 
femora slender margins above subundulate below entire, exter¬ 
nally bicarinate ; posterior femora rather slender the external 
pagina provided with oblique rugulse above with rounded tubercles, 
margins serrulate, above before the knee acute, at the apex of 
femora armed with a large acute genicular spine ; posterior tibial 
margins serrulate lightly compressed, armed with small feeble 
spines; first and third articles of posterior tarsi equal in length, 
pulvilli flat below. Ovipositor unusually long, the blades slender 
strongly denticulate.*

Body of medium size ; pronotum flattened above gibbocristu- 
late, rather stout between the shoulders, rugose tuberculate granu¬ 
late. Head slightly retreating, short, little elevated. Eyes of 
moderate size distinctly globose, prominently exserted. Vertex 
viewed from above little wider than one of the eyes, hardly 
subnarrowed depressed towards the front, lateral margins lightly 
sinuate widened posteriorly, frontal margin subtruncate, viewed 
in front roundly concave, viewed from above not advanced so far 
as the eyes, little carinulae on each side outwardly distinctly 
rounded compresso-elevated acute, not visible in profile ; at the 
lateral margins just behind the fronto-lateral carinulse presenting 
minute supraocular lobes; median carina of vertex appreciably 
distinct though reduced, roundly sloping forward ; between the 
eyes little fossulate on each side, backward terminating by very 
light occipital rugose protuberances. Facial frontal costa above 
between the eyes not at all advanced, between the antennae 
distinctly roundly protuberant, viewed in front narrowly sulcate, 
the rami slightly divergent substraight, facial carina distinct, in 
profile lightly excavate just below the median ocellus. Superior 
ocelli situated between the lower third of eyes, in profile almost 
obscured by the eyes. Antennae filiform unusually long slender, 
articles strongly elongate, inserted just below the eyes but scarcely 
behind a vertical plane with their anterior borders. Pronotum 
truncate in front, posteriorly strongly extended beyond the knee 
of posterior femora acute, slightly passing the wings at the apex ; 
dorsum between the shoulders rather broad trigibbocristate, 
humeral angles distinct outwardly subproduced little depressed ; 
* This genus has certain characters common to the Metrodorinas : for instance, 
it has the length of the first and third articles of the posterior tarsi equal, but the 
strongly triangularly laminate produced posterior angles of the lateral lobes of 
pronotum lead one to place it with the ScelimeninEe.
