outer angle of the emargination being formed l)y the not very 

 obHque apical tooth, which has a very small, almost indistinct one 

 above it, inner spur very slender; intermediate and posterior 

 legs long, femora rounded, inflated at middle, tibiae sinuose, 

 especially the hind ones, not spinose nor transversely carinate, and 

 having the two normal apical spurs ; tarsi long, robust, basal joint 

 of the posterior ones much longer than the apical spurs; claws 

 strong. 



This genus was founded by Klug for the reception of a very 

 singular insect from Dongola, and figured by him. Dr. H. Brauns 

 has discovered in the Orange Eiver Colony a second species of this 

 interesting insect." He met with it in a Termite's nest, in the royal 

 cell or chamber. The generic description, which does not entirely 

 coincide with that of Klug, is made from this species. 



CORYTHODERUS MARSHALLI, BraunS, 



Annal. K. K. Natur. Hofmus. Wien, vol. xv., 1900, p. 164, pi. ix. 



Brick-red, very shining; head parallel laterally in front of the 

 eyes, clypeus elongate and rounded at apex with the margin 

 distinctly refiexed all round, it is roughly punctate, while the 

 remainder of the head is finely, but distinctly, punctate, and each 

 puncture bears a short, erect, flavous seta, there is no trace of 

 transverse or impressed line, and the head is slightly convex ; pro- 

 thorax very little sinuate in the anterior part, but with the outer 

 angles very sharp, narrowed laterally l^efore the median part, and 

 ampliated from there to the posterior angle which is very much 

 rounded, the median part of the disk is very gibliose, the gibbosity 

 being limited laterally by a deep, diagonal, sinuate furrow beginning 

 at a short distance from the anterior outer angle and ending in a 

 deep ovate cavity abutting on the basal margin, the basal space 

 separating these two excavations is greatly raised, and divided into 

 two by a deep longitudinal furrow, at the end of this furrow, and 

 divided from it merely by a very shallow impressed line, is the 

 scutellum which is considerably raised, being almost in a line 

 with the hind part of the gibbosity, and is somewhat hooked towards 

 the l^ase of the elytra which it overhangs ; the sides of the scutellum 

 are fringed with a very dense, and very short, yellowish pubescence 

 not unlike that found in the prothoracic cavities of some Pausst, the
