Key to Scelimena Species. 
Vertex of head strongly narrowed towards the front, small 
frontal carinulse distinctly obliquely convergent, angulate : 
posterior angle of lateral lobes of pronotum armed with one 
strong spine ; femoral margins below armed with more or less 
reduced teeth ; body, usually shining black, mingled with light 
granules, margined with red (plate I., fig. 4); gavialis , De Sauss. 
Vertex sensibly wider, the frontal carinula? oblique, but the 
front margin more sub truncate; lateral lobes of pronotum 
laminato-bidentate ; apex of pronotal process bispiniform ; both 
margins of anterior femora, the lower margins of middle and 
posterior femora armed with strong teeth : body usually grayish 
flavous mottled with fuscous, teeth and margins often yellowish.

Body moderately large, long attenuate posteriorly. Face 
sensibly retreating ; eyes globose, slightly prominent but drawn 
near together. Vertex depressed, strongly narrowed toward the 
front, not advanced quite so far as the eyes, the anterior half 
distinctly sloping forward and on either side longitudinally 
fossulate ; the small elevated oblique carinulae conspicuous from 
above, but hidden in profile by the eyes, converging forward so as 
to form a very narrow angulate anterior border, between the 
eyes slightly interrupted by the forward sloping of the slightly 
conspicuous median carina, the latter very little projects in front 
extending backwards half the length of the vertex. Facial frontal 
costa above between the eyes distinct, but not advanced here quite 
so far as the eyes, precipitately sloping forward, between the 
antennae roundly protuberant, the rami narrowly divergent to the 
median ocellus, median facial carina below distinctly reduced ; 
posterior ocelli conspicuous in profile, situated barely in front and 
on a plane with the lower third of the eyes. Antennae from four 
to four and three-quarter millimeters in length, filiform, middle 
articles strongly elongate, the first basal article flattened, the 
second small and globular ; inserted below the eyes and in a 
vertical plane scarcely behind their anterior borders. Palpi very 
little compressed apically. Pronotum some what shining densely 
granulate, truncate in front, long attenuate acute posteriorly, 
subhorizontal or very slightly upturned toward the apex ; dorsum 
flattened, between the shoulders transversely very lightly irregu¬ 
larly subconvex, the breadth from three and three-quarters to five
