well as to L. cyaneum, Lac., it is from both distinguished by its smooth 

 presternum, from the former by the punctured head, from the latter 

 by the want of the depression at the head. 



5. NODA LEFEVREI, Sp. nOV. 



Broadly ovate, uniformly greenish aeneous. Head coarsely, 

 thorax less strongly punctured. Elytra semipunctate-striate, costate 

 near the apex. 



Length 1| line. 



Head strongly and closely punctate, especially between the eves, 

 where the punctures are of an oblong shape. Eyes very prominent • 

 clypeus also strongly punctured, separated from the face, its anterior 

 margin crescent-shaped ; antennae as long as half the body, the last 

 five joints much thickened, and the terminal one very robust and 

 strongly pointed at the apex, the lower six joints shining greenish 

 aeneous above, fulvous below, the rest black and opaque. Thorax 

 very narrowed towards the apex, with the posterior angles acutely 

 produced ; surface moderately punctured, the punctures not stronger 

 near the sides than those on the disk, and not extending to the an- 

 terior or the posterior margin. Scutellum with a few punctures. 

 Elytra convex, with a very obsolete depression below the base; 

 surface very deeply and regularly punctate-striate near the outer 

 margin, finer and more irregularly towards the suture ; the intervals 

 towards the apex raised in longitudinal costae, of which the third 

 and fourth (counting from the outer margin) are united posteriorly 

 sending off a short costa towards the apex. Underside and legs 

 aeneous, extreme apex of the tibiae and the tarsi darkish rufous. 

 Hab. Costa Rica (volcano of Irazu) ; Guatemala. 

 Closely allied to Nodasemicostata, Lefevre ; but distinguished by 

 the equal punctuation of the thorax, which, in the former species, is, 

 according to the description, strong and dense at the sides. 



6. NODA BALYI, sp. nOV. 



Broadly ovate, aeneous, shining ; antennae, palpi, and legs ferru- 

 ginous. Elytra punctate-striate, with a short round tubercle on 

 the disk of each elytron. 



Length 1| line. 



Head rather deeply but widely punctured, the clypeus not sepa- 

 rated from the face ; antennae with the third, fourth, and fifth joints 

 of equal length, entirely ferruginous. Thorax of the same shape as in 

 N. viridis, distinctly punctate throughout, greenish bronze-coloured. 

 Elytra convex, a little more strongly punctured than the thorax, the 

 punctures arranged in regular striae, the intervals scarcely raised 

 except near the lateral margin and the apex, where they are semicos- 

 tate ; the humeral callus prominent ; and each elytron is furnished at 

 a little distance before the middle with a short round tubercle, which is 

 placed nearer the lateral margin than the suture ; a very shallow trans- 

 verse depression is also visible in certain lights immediately above 

 this tubercle. Underside greenish black, opaque ; legs ferruginous. 



Hab. Guatemala.
