Oblong-ovate, robust, impubescent, of a dull brown green colour. 

 Head short, transverse, obliquely depressed, broadly but slightly 

 elongate ; immediately above the labrum is a transverse impunctate 

 plane, of a pale but more clear green colour than the rest of the in- 

 sect ; above the base of the antennae are two apparently slightly raised 

 tubercles, which are formed by a somewhat deep and well-defined 

 medial and longitudinal fovea, and also by two other shallower 

 depressions near the inner surface of the eyes : eyes tolerably pro- 

 minent ; the surface above the base of the antennae coarsely punctate. 

 Thorax transverse, broader than the head, narrowed and considerably 

 depressed in front ; the sides distinctly marginate ; the surface finely 

 and closely punctate. Scutellum triangular. Elytra robust, sub- 

 elongated towards the apex, punctate-striate, the surface between 

 the stria? being very finely punctate ; the colour of a dark dull olive - 

 green ; at the apex broadly rufo-fuscous, bounded by a suffused line 

 of darker fuscous, the boundary-line between the two colours being 

 situate at the distance from the apex of one-third of the whole length 

 of the elytra. Antennae fine, filiform, short, the second and third 

 joints being equal in length, and shorter than the first ; flavo-ferru- 

 gineous. Legs flavo-ferrugineous ; the posterior femora being of an 

 ohVe-green colour, at the apex suffused with rufo-fuscous. Abdomen 

 flavo-ferrugineous, at the apex suffused with rufo-fuscous.

3. Phylacticus olivaceus. (Tab. IV. fig. 6.) 



P. oralis, latus, robustus, olivaceus; capite brevi, elongatido, inter 

 oculos oblique foveolato, punctate ; ihorace transverso, ad basin 

 late, apicem versus sensim attenuate, angulis anticis depressis, 

 punctate ; elytris latis, ad humeros thorace paulum latioribus, 

 punctato-striatis ; antennis filiformibus, fuscis ; pedibus ferru- 

 gineis, fusco suffusis. 

 Long. corp. 2| lin., lat. 1^ lin. 



Oval, broad, subdepressed, of a brownish-green colour throughout.
