broadly rounded, and the anterior angles subrotundate ; the disk 

 contains some remote but strongly marked punctures, while the 

 sides and the commencement of the posterior margin is strongly im- 

 pressed with large punctures, distinctly visible to the naked eye ; 

 surface uniformly darkish brown. Scutellum elongate, triangular, 

 smooth, black. Elytra scarcely wider at the base than the thorax, 

 slightly widened behind the middle, surface rather convex ; they are 

 regularly striate-punctate on their inner half, while the outer por- 

 tion contains numerous irregularly distributed punctures, not so 

 deeply impressed as those near the suture, of a light testaceous 

 colour, the suture and four spots on eacii elytron of a greenish black 

 colour, and placed as follows :— two longitudinal streaks, a little 

 widened at their extremities a little below the base, of equal size, 

 one of which is situated near the scutellum, the other near the ex- 

 terior margin ; a transverse vitta a little behind the middle, not 

 touching the lateral nor the sutural margin, sinuate in middle, and 

 forming at the sutural end a short angle parallel with the suture ; 

 and another short oblique spot near the apex : this spot is some- 

 times connected with the transverse vitta by a thin line. Body 

 below shining cupreous, with a greenish tinge. Abdominal segments 

 each with a shallow fovea near the sides. 



Far. a. The spots on the elytra not much darker than the ground- 

 colour, and indistinct (immature?).

Collected by Mr. Janson. 



Although this beetle is, in the punctuation and markings of the 

 elytra, quite different from other species belonging to this genus, its 

 structural characters agree in every particular. 



17. Calligrapha elegantula, sp. nov. 



Oblong, moderately convex ; head shining, greenish black, with a 

 longitudinal middle line, strongly punctate as well as the epistome ; 

 labrum fulvous at the base ; antennae with the first six joints metallic 

 violet-blue above, testaceous below, the rest black, and longer than 

 broad. Thorax of the same colour as the head, the anterior margin 

 slightly widened in the middle, the posterior one broadly rounded, 

 each side with a distinct rounded fovea, variolose punctate ; disk re- 

 motely and finely punctured. Scutellum greenish, smooth. Elytra 

 broader at the base than the thorax, straw-coloured, with the fol- 

 lowing shining greenish black markings : — a common sutural vitta, 

 commencing a little below the base, slightly narrowed in the middle, 

 and extending to the apex ; a longitudinal narrow stripe, club- 

 shaped at its extremity, accompanies the sutural vitta without touch- 

 ing it from the first third of each elytron to a little behind the 

 middle, and having a roundish spot above it near its base ; an 

 oblique large spot on the shoulder, pointed at its apex ; three trans- 

 verse spots, of which the first is the smallest, the others of irregular 

 shape below the humeral one, all at equal distance from the lateral 

 margin, which remains of the ground-colour; three small round
