The segments are sometimes margined with green ? Cephalic segment ovate, cordate ; ba- 

 silar segment large, transverse : labium and mandibles ferruginous : teeth six, black 

 and triangular ; dental plates punctured ; mandibular tooth absent. Posterior pair of 

 legs strong ; femoral joint elongated, with the upper surface convex, the external mar- 

 gin subacute, and the internal with five strong spines, the four anterior of which are 

 arranged in two alternating series, and the fifth, or apical one is very long and acute in 

 the female, and is developed into a broad lancet-shaped appendage in the male. Inferior 

 surface armed with four and sometimes five strong spines, in two longitudinal series. 

 Lateral anal appendages very long, rounded, curved and slender, with a strong spine 

 on the external margin and the apex trifid. Preanal scale subcordate, deeply emar- 

 ginated.

This species very closely resembles H. spinosa, and may perhaps be only a variety of it. The 

 colour of the dried specimen in the Museum is orange-yellow with green fasciae, the 

 respiratory plates deep orange, and the labium and mandibles ferruginous : mandibu- 

 lar tooth absent ; teeth six, large, black : femoral joint of the posterior pair of legs 

 longer and stronger than the tibial; superior surface subconvex; external margin 

 rounded, internal armed with five spines arranged in two alternating series, the apical 

 spine large and acute. Inferior and lateral surfaces flattened, with three spines on the 

 external and two on the internal margin. Lateral appendages elongated, with the apex 

 bifid, and two spinulae on the posterior inferior surface. Preanal scale slightly elon- 

 gated, subquadrate, deeply emarginated, with the angles rounded.
