of the thorax, which in the species referred to is finely punctured on the disk and strongly 

 at the sides ; the elytra in the present species have also the interstices raised into eight 

 costee at the apex, while JV. semicostata has only six. 



10. Noda tarsata. 



Broadly ovate, dark purplish below, base of the antenna? and the legs ferruginous ; above metallic green or 

 purplish ; thorax finely and closely punctate ; elytra punctate-striate ; tarsi piceous. 



Length 2 lines. 



Upper part of the head distinctly but remotely punctured, obsoletely depressed at the middle ; clypeus not 

 separated from the face, more strongly and closely punctured than the head ; palpi and the first six joints 

 of the antennae ferruginous ; thorax more than twice as broad as long, its sides rounded and distinctly 

 narrowed in front, anterior angles very acute and slightly produced, sides finely margined, surface metallic 

 green, closely and rather evenly covered with fine punctures ; scutellum subpentagonal ; elytra convex, 

 widened towards the middle, surface finely and rather regularly punctate-striate, the punctures arranged 

 in single rows, the interstices at the extreme apex somewhat raised and very finely transversely wrinkled ; 

 tarsi greatly dilated in the male. 



§ . Elytra more strongly and more irregularly punctured, the humeral callus distinctly raised and elongate. 



Hah. Mexico, La Parada (Boucard, coll. SalU). 



Three specimens of this very distinct species are contained in M. Salle's collection. 

 The ferruginous legs and piceous tarsi, and especially the broadly ovate shape of the 

 present insect will easily distinguish it from its allies. The only species with which it 

 might be confounded is N. rufijpes, Lefevre, which differs in the punctuation of the thorax 

 and the uniformly coloured legs and tarsi. 



11. Noda violaceipennis.

Hab. Guatemala, Aceytuno (Salvin), Capetillo (Champion). 



Of this species, which was described by me from specimens collected by Mr. Salvin, 

 several more have since been received from Mr. Champion, which show no material 

 difference, but belong all to the male sex. The species is of a dark blue ; the thorax is 

 transversely convex, finely punctured; and the antennae and legs are proportionally 

 much longer than is generally the case. The female is unknown to me. 



12. Noda boucardi. 



Noda boucardi, Jacoby, P. Z. S. 1878, p. 986. 

 Eab. Guatemala, Palin (Salvin). 



In the colour of its upper surface this species is allied to the preceding one, but differs 

 in the red tibiae and tarsi and the different shape of the thorax, which in the present 

 species is much less transverse and more narrowed in front. From blue specimens of 

 If. viridis it is distinguished by the colour of the femora, which in the last-named
