GRAPTODERA MODESTA. 155 



in Lactica and Diphaulaca , with this difference , that the 

 transverse groove extends upwards along the sides for a 

 little distance. H. modesta is closely allied to H. petulans 

 Har. and still more closely to H. parvula Jac, but differs 

 from the former by the colour of the underside , and from 

 the latter by its larger size and the much more finely 

 punctured elytra. I also possess this species from Para. 



Lactica Har old i, n. sp. 



Below piceous; head and the scutellum black, thorax 

 and elytra fulvous , the latter minutely punctured. — 

 Length 1 line. 



Head entirely black , with a few deep punctures near 

 the eyes ; the frontal tubercles small ; palpi obscure fulvous ; 

 antenuÊB rather short, not extending to half the lengthof 

 the elytra , black , the four lower joints fulvous , the third , 

 one half longer than the second and more slender, the 

 following joints somewhat thickened; thorax transverse, 

 rather more than twice as broad as long, the sides rounded, 

 slightly narrowed towards the apex, the thoracic groove 

 sinuate, moderately deep and bounded at the sides by a 

 perpendicular groove, the surface not visibly punctured ; 

 scutellum black ; elytra rather convex , extremely finely 

 punctured. 



The very small size, the black head, scutellum and un- 

 derside separates L. Haroldi from several nearly similarly 

 coloured species. 



Sy St ena bifasciata, n. sp. 



Testaceous ; thorax finely punctured ; elytra closely and 

 finely punctured , the suture and a narrow lateral stripe , 

 abbreviated posteriorly , piceous. — Length 2 lines. 



Head scarcely visibly punctured, the frontal tubercles 

 rather obsolete; antennse short, testaceous, the joints 

 stained with fuscous or entirely of that colour, the third
