on each side, near the scutellum; body beneath glossy blackish ; antennze 
yellowish ferruginous, scarcely half the length of the body ; legs black- 
ish; tarsi yellowish ferruginous. Length 33 lines. 
A small narrow species, with yellowish ferruginous tarsi. 
Drerysvus [| Amarygmine }. 
Caput retractum ; clypeus truncatus. Labrum rotundatum. Mandibule 
apice integra. Oculi mediocres, modice approximati. Palpi labiales 
basi approximati. Zabiwm transversum, emarginatum. Mentum tra- 
peziforme, basi sensim angustius, ad latera margine elevato. Mazille 
lobo interno mutico. Antenne longiuscule, apicem versus crassiores, 
art. 3 elongato, 4-10 obconicis, ultimo ovato, apice oblique truncato. 
Prothorax transyersus, utrinque rotundatus et tenuiter marginatus, 
antice angustior, basi subbisinuatus. Elytra ovata, prothorace basi vix 
latiora. Pedes longiusculi; femora sublinearia; tébce paulo curvate, 
calcarate ; tarsi lineares, subtus ciliati, postici art. basali elongato, Pro- 
sternum productum, in cavitate mesosterni receptum. Corpus elliptico- 
ovatum, convexum. 
I have long ago received specimens of this insect from M. Deyrolle, 
under the name here adopted. As the mesosternum presents no 
concavity as in the Strongyline, I have placed it with the Amaryg- 
min, with none of whose genera, however, does it seem to have any 
very marked affinity. The females appear to be considerably broader 
than the males. There are several species, one of them is from Aru. 
Dietysus confusus. 
D. elliptico-ovatus, fusco-eeneus, nitidus ; elytris striato-punctatis. 
Hab. Java. 
Elliptic-ovate, dark copper-brown, very glossy, and polished ; head 
and prothorax minutely punctured; scutellum triangular; elytra finely 
striato-punctate, the punctures narrow and linear, the spaces between 
the striz broad and flat; body beneath and legs brown, less shining 
than the back ; anterior tarsi with the claw-joint as long as the pre- 
ceding joints together. Length 6 lines. 
Spheniscus* cyaneus. 
S. cyaneus, nitidus; elytris brevibus, in medio obtuse elevatis, grosse et
