Moderately convex, slightly widening posteriorly. Head transverse, 
with a small median frontal lobe. Eyes small, lateral, situated on 
a lobe that is received into a corresponding excavation in the front 
margin of the first thoracic segment. Segments of the thorax short. 
Abdomen two-jointed, terminal segment tuberculate or rugose above, 
posterior margin notched, with a median lobe in the centre of the 
notch. Caudal appendages thick, usually short, rami equal, or rather

Moderately convex, nearly smooth. Head small, frontal lobe very 
small, obtuse. Lateral margins of the segments of the thorax all with 
a narrow marginal line, with the postero-lateral angles acute. Antero- 
lateral lobe of the first segment of the thorax narrow-triangular, acute, 
produced forward beneath and beyond the eyes. Postero-lateral lobe 
of the last segment of the thorax produced backward, and terminating 
in a short spine, curving upward; posterior margin of the segment 
nearly straight. Last segment of the abdomen broad, convex, granu- 
lous and slightly hairy, with a slight, more distinctly granulous 
elevation on its upper surface near its base, emargination quadrangular 
with the median lobe narrow. Rami of caudal appendages unequal, 
the inner not quite reaching to the extremity of the segment, broad, 
truncate at the end, the outer nearly as long again, narrowing to the 
extremity, which is acute. Upper antenne much enlarged at base, 
the second joint received into an emargination of the first joint.
