more deeply sinuate, the reflexed pronotal lateral area with more ele- 
vated humeral bladder and with its inner margin anteriorly touching 
the much larger apical vesicle, and the elytra much less variegated. 
It is also related to the Bornean C. picturata Dist. (by Distant 
wrongly referred to Elasmognathus Fieb.), from which it differs by 
anteriorly truncate pronotal apical vesicle, the outwardly more produced 
humeral bladder, and the somewhat differently coloured elytra. 
The three type-specimens from Nura-Ellia are, apart from the 
mutilated antennae, in good condition. This species has not been 
rediscovered’ since it was described. 
Stat, who had received a type-specimen of this species from 
Motschulsky, placed it in his genus Cysteochila, and Distant 
cites C. tingoides as the type of the genus. But as Stál founded a 
distinct division of the genus on this species, adding ,haec species 
quodammodo ad Elasmognathus appropinquat*, it is clear that he did 
not consider it a typical Cysteochila, and the species sordida Stal 
must be regarded as the type of the genus. Distant took no 
notice of the fact that Stäl had founded the division of Cysteochila, 
to which he referred tingoides, on the same character upon which 
Distant himself (1903) founded his genus Bredenbachius, The other 
character relied on by Distant, ,elytra with the costal area abruptly 
divided and laminately deflected from the discoidal area‘, is of no 
value and least of all a generic character, there being no constant 
difference in this respect between Bredenbachius and Cysteochila. 
Later (1909) Distant described as appertaining to Bredenbachius 
some species belonging partly (consanguineus and humeralis) to Stál's 
division a (= Bredenbachius) of Cysteochila, partly (delineatus and 
Annandalei) to Stál's typical division aa of that genus. The only 
difference between these groups consists in the degree of development 
of the inflated humeral elevation, but this is of gradually different 
shape according to the species, and Bredenbachius cannot be gene- 
tically separated from Cysteochila. 
I take the opportunity of mentioning that the Bornean Elas- 
mognathus Hewitti Dist. (1908) belongs to the genus Diplogomphus 
Ногу. (1906) and is closely related to D. Greeni Kirby, from which 
it differs principally by the less strongly developed humeral elevations.
