NODA. 115 



3. Noda irazuensis. 



Oblong-ovate, dark aeneous below; legs and base of the antennae ferruginous; above metallic green, very 

 closely and finely punctured ; elytra closely and regularly punctate-striate. 



Length 1| line. 



Head remotely and rather finely punctured at the vertex, lower part of face strongly punctured ; the clypeus 

 triangular and distinctly separated from the face ; antennae as long as half the body, piceous, the first six 

 joints fulvous ; thorax transverse, the sides but very slightly rounded and narrowed in front, surface finely 

 and closely punctured ; elytra very closely and regularly punctate-striate, the interstices near the apex 

 slightly costate. 



2 • Antennse shorter ; elytra with three very distinct longitudinal costae near the lateral margin, the first two 

 of which are interrupted below the base and have generally a short transverse tubercle between them. 



Eab. Costa Eica, Volcan de Irazu, Cache (Rogers). 



Nearly allied to N. costipennis, Lefevre, from Brazil, but differing in the more closely 

 and regularly punctured elytral strise, as well as the lateral costse, which in the present 

 species are much more regular and less interrupted, the thorax at the same time being 

 much more distinctly punctured. The male of this species is very like that of N. viridis, 

 Jac. ; the elytral punctuation of the latter species, however, is much finer and more 

 remotely placed, leaving broad interstices between. Numerous specimens were obtained 

 in Costa Rica by Mr. Rogers. 



4. Noda lateralis. 



Oblong, greenish aeneous below ; antennae and legs ferruginous, above aeneous, metallic green, or blue ; thorax 

 closely punctured ; elytra distinctly geminate- punctate-striate. 



Length 2 lines. 



Head strongly and rather closely punctured ; clypeus triangular, distinctly separated from the face; labrum 

 and palpi fulvous ; antennae of half the length of the body, entirely ferruginous, the apex of the terminal 

 joint darker ; thorax transversely convex, the sides much rounded, anterior and posterior margin nearly 

 straight, surface very closely but rather finely punctate ; scutellum much broader than long, pentagonal ; 

 elytra rather elongate, much more strongly punctured than the thorax, the punctures arranged in double 

 rows on the disk, but in single lines near the apex ; legs and tarsi ferruginous. 



$ . Elytra with three strongly raised longitudinal costae near the lateral margin, of which the second or middle 

 one does not extend to the base, but commences below the middle ; the outer costa begins from the 

 shoulder, and runs in a rather oblique line close to the lateral margin ; the spaces between them are 

 strongly punctured in single rows ; a short tubercle is sometimes present below the base. 



Eab. Mexico, Jalapa (Edge), Cosamatopan, Juquila, Tepansacualco, Peras, Totoni- 

 sapan, Silao (Boucard, coll. Salle), Guanajuato (Duges, coll. SallS); Guatemala, near 

 the city, Capetillo, Zapote, Duerias (Champion), Aceytuno (Salvin). 



The present species is of a rather elongate shape, and, although closely allied to 

 'N. cretifera and N. costipennis, Lefevre, may be at once recognized by the colour of the 

 antenna? and the legs; the elytral costae in the female are also of different shape, and 

 the punctuation is closer; the elytral tubercle below the base is in most instances 

 absent, and only present in a few specimens which do not differ in any other respect. 

 Numerous specimens of this species were sent home by Mr. Champion, principally from 

 Capetillo Some Mexican specimens from M. Salle's collection are metallic blue, and
