different shape of its groove, and the general colour seem to point 

 to an allied but different genus. 



Enneamera ceylonensis, sp, nov. 



Testaceous ; a spot at the vertex and the soutellum black ; head 

 and thorax im punctate ; elytra scarcely visibly punctured, testa- 

 ceous, a triangular-shaped spot at the base and a narrow trans- 

 verse band below the middle reddish fulvous. 



Var. Elytra entirely dark fulvous. 



Length 2 lines. 



Head broader than long, impunctate, a large spot at the vertex 

 black ; frontal tubercles obsolete ; labrum piceous. Antennae 

 entirely pale fulvous, the second and third joints short, the rest 

 transversely dilated. Thorax three times as broad as long, widened 

 at the middle, the sides nearly straight, narrowed in front, the 

 anterior angles slightly thickened and distinct ; the surface entirely 

 impunctate, pale testaceous. Scutellum black. Elytra microscopi- 

 cally finely punctured, very convex and rounded, of a yellowish 

 colour, a transverse triangular-shaped band at the base, not quite 

 extending to the sides, and marked with a more or less distinct black 

 spot at the shoulder, reddish fulvous ; the narrow band behind the 

 middle of a more piceous colour ; the outer margin of the posterior 

 tiliise with a row of small black teeth or spines. 



Besides the above-named fulvous variety, which does not vary in 

 other respects from the tvpical form, I possess a specimen in my 

 collection (also from Ceylon) in which the posterior band of the 

 elytra is divided into two small spots. 



Phyllotreta discoidea, sp. nov. 



Head, thorax, and the abdomen fulvous ; antennae, the breast, and 

 legs black ; elytra scarcely visibly punctured, testaceous, all the 

 margins narrowly black. 



Length 1| line. 



Head impunctate, fulvous, the frontal tubercles transverse, narrow 

 and very distinct. Antennae half the length of the body, black, the 

 third joint smaller than the second, the following ones gradually 

 thickened. Thorax transversely quadrate, the sides slightly rounded ; 

 the surface rather flat, with a very obsolete and shallow depression 

 at the middle of the sides, entirely impunctate. Scutellum black. 

 Elytra parallel, not covering the pygidium, their surface only visibly 

 punctured when seen under a strong lens, testaceous or yellowish, 

 margined with black, the sutural margin generally narrowed near 

 the base. Breast and legs black, the anterior femora slightly stained 

 with fulvous below; the abdomen, with the exception of the last 

 segment which is black, fulvous. 



Bogawantalawa. 



P. discoidea may be recogni2ed by the small third joint of the 

 antennae, which is smaller than the second (an exceptional structure 

 as a rule), and by its general coloration.
