spine on the twenty-first; in the different position and greater 
proportionate length of the ventral spine of the femur of the 
anal legs, the spine equalling the distance of its base from 
the proximal end of the joint and about half the distance to 
the distal end ; and in the form of the cephalic plate, which 
is proportionately broader and which has the caudal margin 
mesally straight instead of convexly rounded. Head and 
first tergite chestuut, the remaining portion of dorsum 
browner, with the caudal border of each plate crossed by a 
dusky stripe.

Antennee composed of seventeen articles, of which the first 
two are very sparsely hairy, the others more deusely and 
finely so, the third nearly to base. Tergites margined from 
tenth caudad ; paired sulci present on tergites from the fifth 
caudad. Prosternal dental plates each with three distinct 
teeth. Sulci of sternites in middle and posterior region 
reaching to near middle of plate ; plates of posterior region 
couspicuously uneven and roughened with short ridges, 
swellings, and granules. Last ventral plate narrowed 
caudad ; caudal margin widely incurved. Coxopleural 
processes with two (or but one) distal points, armed laterally 
with three spines and dorsally with one. Only first four 
pairs of legs with two tarsal spines; others with two to the 
twentieth inclusive. Femur of anal legs ventrally with 
three spines toward outer side, three to six toward inner, 
two stouter ones on mesal surface and one at distal end 
above. Colour above, in general, olive-brown, plates clearer 
green along caudal and lateral edges; legs fulvous, the 
posterior pairs darker, brown or olive-brown ; antenne dark 
olive. .

This species lies in the small group in which the anal legs 
are wholly unarmed. It is, among these, apparently most 
like the Colombian O. burgeri, Attems. Antenne consisting
