1887.] PHYTOPHAGOUS COLEOPTERA. OF CEYLON. 97 



labrum piceous ; palpi long aud slender. Antennse inserted close to 

 the inner margin of the eyes, scarcely extending in length to the 

 base of the thorax, the second joint short and thickened, the third 

 more slender and longer, the rest gradually widened and trans- 

 versely shaped ; black, the four basal joints fulvous. Thorax at 

 least three times broader than long, pale fulvous, the sides straight 

 and forming a distinct angle before the middle, the posterior margin 

 evenly and moderately rounded ; the surface without depressions, 

 smooth and nearly impunctate. Scutellum broadly ovate, black. 

 Elytra convex, subcylindrical, closely and distinctly punctured, 

 fulvous, each elytron with a broad black band commencing at the 

 middle of the base and extending below the middle, the outer 

 margin deeply concave at the middle. Legs fulvous, the posterior 

 femora piceous as well as the sides of the breast. 



The elytral band is slightly widened at the apex, and approaches 

 gradually towards the suture without, however, touching tlie latter. 



Tegyrius (gen. nov. Halticinorum). 



Ovate, subcylindrical. Antennae slender, filiform, the third joint 

 slightly longer than the second. Thorax transversely subquadrate, 

 the surface transversely but obsoletely grooved near the base. 

 Elytra convex, broader than the thorax, without depressions, finely 

 and semiregularly punctured. Posterior femora strongly incrassate, 

 their tibiae dilated and longitudinally channelled, their apices with a 

 small spine ; the first joint of the posterior tarsi as long as the three 

 following joints together. Claws appendiculate. Prosternum 

 broad, subquadrate. Mesosternum broader than long, its base 

 concave-emarginate. Anterior coxal cavities open. 



Tegyrius has the general shape and appearance of Philogeus, but 

 differs in the filiform antennae, the much longer metatarsus of the 

 posterior tarsi, and in the appendiculate, not bifid, claws. From 

 Longitarsus the genus may be distinguished by the transverse 

 sinuate groove of the thorax and the broad prosternum. 



Tegyrius metallicus, sp. nov. 



Black ; antennae, legs, the posterior femora excepted, testaceous ; 

 above metallic greenish aeneous ; head and thorax impunctate ; 

 elytra very finely semipunctate- striate. 



Length 1 line. 



Head impunctate ; the frontal tubercles and the carina very 

 narrow and rather indistinct. Antennae nearly as long as the body, 

 the fourth joint one half longer than the third, the second thickened. 

 Thorax scarcely twice as broad as long, the sides straight, the 

 anterior angles obliquely truncate and shghtly thickened, the basilar 

 transverse groove sinuate, not very deep and not extending to the 

 sides ; the disk entirely impunctate. Elytra convex, subcylindrical, 

 without basal depression, the shoulders not prominent, the apices 

 rounded ; surface very closely and minutely punctured, the punctua- 

 tion arranged in semiregular rows ; the anterior tarsi, the posterior 

 femora, and the inner side of the posterior tibiae blackish.
