on each side, near the scutelluni ; body beneath glossy blackish ; antennae 

 yellowish ferruginous, scarcely half the length of the body ; legs black- 

 ish ; tarsi yellowish ferruginous. Length .S| lines. 



A small narrow species, with yellowish ferruginous tarsi. 



DiETYsus [Amarygminge]. 

 Caput retractum ; clypeus truncatus. Labrum rotundatum. McmdihulcB 

 apice integrte. Oculi mediocres, niodice approximate Palpi lahiales 

 basi approximati. Labium transversum, emarginatum. 3Ienttan tra-

 lobo interno mutico. Antennce longiusculse, apicem versus crassiores, 

 art. 3 elongato, 4-10 obconicis, ultimo ovato, apice oblique truncato. 

 Prothorax transversus, utrinque rotundatus et tenuiter marginatus, 

 antice angustior, basi subbisinuatus. Elytra ovata, prothorace basi vix 

 latiora. Pedes longiusculi ; femora sublinearia ; tihice paulo curvatae, 

 calcaratse ; ^arsHineares, subtus ciliati, postici art. basali elongato. Pro- 

 sternum productimi, in cavitate mesosterni receptum. Corpus elliptico-

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 Strongylinae, I have placed it with the Amaryg- 

 minae, 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.
