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 fascia-, 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.
