the disk with a strongly impressed line, including a squarish space, 
and opening out into three short canals posteriorly, the side slightly 
margined and terminating behind in a nearly acute angle; scutellum 
triangular; elytra with five narrow raised lines on each, the sutural 
one nearly obliterated, the interval with two slightly punctured lines ; 
body beneath dark chestnut-brown, with small scattered punctures ; 
palpi and antenne at the base ferruginous. Length 2 lines, 
Though this species has the same impressed line on its prothorax 
as the last, in its outline and glossy surface it is more akin to the 
Australian Bothrideres anaglypticus, Germ., but is less depressed, and 
the sides of the elytra more parallel. The two following species are 
provisionally assumed to be aberrant members of the group. 
Bothrideres rhysodoides.

Bothrideres nocturnus.

Dastarcus vetustus. 
D. oblongo-ovatus, fuscus; prothorace antice subrotundato, postice paulo 
constricto; elytris punctato-sulcatis, punctis magnis, interstitiis seri- 
atim griseo squamosis, postice obsolete emarginatis.

Oblong-ovate, dark brown; head small, rather remotely punctato- 
squamose ; basal joint of the antennze ferruginous; prothorax gradually 
rounded anteriorly, slightly contracted at the base, covered with erect 
greyish scales; elytra moderately convex, very slightly emarginate 
posteriorly, punctato-sulcate, the punctures large and oblong, the inter- 
stices with mostly a single row of greyish scales; body beneath dark 
brown, subnitid, with coarse remote punctures; tarsi ferruginous, 
shining. Length 4 lines, 
Smaller and less robust than Dasturcus confinis, the scales on the 
elytra mostly in single rows, and with only a faint trace of the deep 
emargination which characterizes that species. 
Dastarcus pusillus. 
D, oblongo-ovatus, fuscus; prothorace lateribus subrotundatis, postice 
vix constricto ; elytris basin versus elevatis, postice obsolete emargi- 
natis, punctato-striatis, interstitiis serlatim griseo squamosis. 
Hab. Ceram.
