NODA. 121 



Hab. Mexico, Oaxaca, Yolos {Boucard, coll. SalU), Cuernavaca (SalU). 



From all described species the present one may be at once recognized by its broadly 

 ovate or rounded shape, by the fine and close punctuation of the thorax, and by the 

 generally plainly visible smooth longitudinal spaces of the elytra. Its colour varies 

 from green or blue to dark seneous. The specimen figured is from Oaxaca. 



19. Moda dispersa. 



Broadly ovate, metallic green ; antennae and legs fulvous ; thorax finely and distantly, elytra strongly and very 

 remotely geminate- punctate-striate. 



Length 2 lines. 



Head with a few deep punctures, especially at the clypeus, the latter not separated from the face ; thorax 

 transverse, sides much rounded, the anterior angles acute and produced outwards, surface finely but 

 distantly punctured ; elytra broad, convex, and regularly rounded towards the apex, surface deeply and 

 very remotely punctured, the punctuation on the disk arranged in double rows, but singly towards the 

 apex ; the outer rows parallel with the lateral margin, but not quite extending to the apex, the two rows 

 which precede abbreviated behind the middle. Female unknown. 



Hab. Mexico, San Andres Tuxtla {Salle). 



The deep and remote punctuation of the elytra, in connexion with the colour of the 

 antennge and the legs, separate the present species from all others. In shape it approaches 

 N. tarsata, but differs in its sculpture and the colour of the tarsi. 



20. Noda bicallosa. 



Broadly ovate, greenish aeneous below ; antennae and legs fulvous ; above metallic green ; thorax closely and 

 distinctly punctured ; elytra geminate- punctate-striate, the interstices broad and smooth, each elytron 

 with a longitudinal and transverse tubercle. 



Length 2 lines. 



Head very deeply and remotely punctured ; clypeus separated from the face at the sides only, its anterior 

 margin concave ; labrum very narrow, transverse, fulvous ; antennae of the same colour ; thorax trans- 

 versely convex, much narrowed anteriorly, the anterior angles acute but not produced, sides but slightly 

 rounded, surface closely and moderately strongly punctured ; elytra distinctly but finely punctate-striate, 

 the punctures arranged in double rows, distinct to the apex, but in single rows only at the latter place, 

 the interstices between them broad and smooth, slightly costate near the apex ; a short elongate and 

 another transverse tubercle is placed below the shoulder of each elytron ; legs dark fulvous, covered (like 

 the abdomen) with yellowish pubescence. Male unknown. 



Hab. Guatemala {SalU). 



In shape this species resembles N. dispersa, N. curtula, &c, but differs from all of 

 them in the broad interstices of the elytra and the two tubercles of the latter, in 

 connexion with the colour of the legs. 



21. Noda laevicollis. 



Narrowly oblong, greenish aeneous below; above aeneous, opaque; head and thorax impunctate; elytra 

 extremely finely ge min ate- punctate-striate ; legs and base of the antennas fulvous. 



Length 1 line. 



Head swollen, totally impunctate, greenish aeneous ; eyes very distant ; antennae very long, extending to two 

 thirds the length of the body, the first six joints fulvous, the rest black ; thorax subquadrate, about one
