PHYLACTICTJS. 115 



4. Phylacticus prasinus. 



P. oblongo-ovatus,robustus,punctato-striatus, impubescens, olivaceus; 

 capite inter oculos Y foveolato, ad basin fortiter punctato ; thorace 

 transverso, angulis anticis acutis, punctatis ; elytris robmtis, 

 punctato-striatis ; antennis filiformibus, fuscis ; pedibus olivaceis. 



Long. corp. 2| lin., lat. 1-J- lin. 



Oblong-ovate, robust, punctate -striate, impubescent, of a dull green 

 colour throughout. Head slightly produced in front ; immediately 

 above the labrum is a transverse depression : eyes tolerably large, 

 situated at the base of the head ; between the eyes, and immediately 

 above the base of the antennae, is a longitudinal well-defined fovea, 

 which is terminated at its upper extremity by two oblique canalicula- 

 tions extending to the inner margins of the eyes, thus together form- 

 ing (more distinctly and deeply than in the allied species, P. olivaceus) 

 the character of the letter Y ; the surface between it and the base of 

 the head is broader and more deeply granulated : in colour of a uni- 

 form dull green, with the exception of the labrum and the insertion 

 of the antennae, which are flavous. Thorax transverse (not constricted 

 anteriorly as in P. olivaceus}, the anterior angles depressed and di- 

 stinctly acute ; the sides are very finely marginate ; the surface finely 

 and thickly punctate. Scutellum triangular, impunctate, of a fuscous 

 olive-green colour. Elytra somewhat broader than the thorax, robust, 

 deeply punctate-striate, impubescent. Antennce robust, filiform, dark 

 fuscous. Abdomen flavous. Legs robust, of a dull-green colour 

 throughout. 



P. prasinus differs but slightly from P. olivaceus ; the modified form 

 of the thorax and of the basal part of the head seem sufficiently to 

 separate it as specifically distinct. 



Para. In the collection of M. Chevrolat. 



5. Phylacticus pollinosus. 



P. oblongo-ovalis,parallelus, subconvexus,flavo-fulvus; capite haud 

 producto, ad basin punctato et nigro ; thorace transverso, punc- 

 tato, pubescenti ; elytris punctato-substriatis, pubescentibus ; an- 

 tennis nigris ; pedibus testaceis, tibiis tarsisque anterioribus fe- 

 moribusque posticis (ad basin) fuscis. 



Long. corp. 2J lin., lat. 1 lin. 



Oblong- ovate, robust, subpubescent, flavo-fulvous. Head short, 

 depressed, not produced; eyes large, distant, extending laterally 

 nearly to the anterior angle of the thorax ; surface of the head finely 

 granulated ; at and below the insertion of the antennae pale fulvous, 

 at the base black. Thorax transverse, rectangular; the anterior
