SPOLIA ZEYLANICA. 
small, the inferior sinus large and angularly excavate. Elytra very 
small, lanceolate ; wings not reaching to the pronotal apex, very 
largely concealed. Anterior femoral margins above armed with 
three strong teeth, minutely serrate, at the base often presenting 
small, secondary denticles, below strongly bi- or tri-dentate-lobate; 
middle femora not so compressed, margin above triserrate the first 
two teeth distinct acute, the third smaller, below strongly biden- 
tate acute or subspinose ; posterior femora narrowed behind, the 
knee small, femoral margins crenate above arcuate anteriorly, 
straight posteriorly, presenting two distinct obtuse teeth, lower 
margin provided with one obscure denticle ; tibial margins not 
appreciably dilated, serrulate unarmed ; first article of posterior 
tarsi very slender little lower than the third, the first pulvillus 
small acute, widely separated from the second, the second small 
acute, the third flat below. There are marked variations in the 
size and arrangement of the teeth of the femora which may be 
more or less deficient or strongly developed, being sometimes 
lobuliform, spiniform, or dentiform. The teeth moreover differ 
on one side from those of the opposite side and in one sex from 
the other. A correlation is shown in a similar tendency of the 
teeth to vary on the inferior margin of the lateral lobes of the 
pronotum, where the second tooth is more often spiniform, or some¬ 
times the margins are distinctly tridentate ; the anterior lateral 
margins not infrequently present one or two additional tubercles.
