obsolete, and the scarcely visible punctuation of the elytra, in connexion with their pale 

 metallic'greenish colour and the more transversely shaped thorax, justify the separation 

 of A. semipunctata from its allies. 



8. Aphthona paUipes. (Tab. XXI. fig. 18.) 



Below piceous; basal joints of the antenna and the legs pale testaceous; above pale fulvous, with a distinct 

 metallic seneous gloss ; elytra finely punctate-striate. 



Length f line. , 



Head impunctate; the frontal tubercles distinct; carina short, but rather strongly raised; labrnm and the 

 apices of the mandibles piceous ; antenna? slender, two thirds the length of the body, testaceous, the four or 

 five terminal joints fuscous, the third and fourth joints equal in length, the fifth distinctly longer; thorax 

 about one half broader than long, entirely impunctate, the sides slightly rounded and obliquely cut in 

 front of the anterior angles, forming an obsolete small tooth; elytra with a very obsolete depression 

 below the base, extremely finely punctate-striate, the punctures visible nearly to the apex ; legs entirely 

 testaceous ; first joint of the posterior tarsi as long as the two following joints united ; claws simple.

Closely allied to A. deyrollei, but differing in the colour of the antennae [which is 

 constant in the numerous specimens from the above localities], the paler general colour 

 of the upper surface, and the elytral basilar depression, of which there is no trace in 

 A. deyrollei. 



9. Aphthona brunnea. 



Below piceous; above dark brown; legs fulvous ; thorax impunctate; elytra extremely finely punctate-striate, 



the apex not visibly punctured.

Hab. Guatemala, near the city, Aceytuno (Champion). 



Of this species, as well as of the next, only a single specimen is before me ; the 

 uniform brown colour of the upper surface, and the extremely finely punctate-striate 

 elytra, will assist in distinguishing A. brunnea from its allies ; the frontal tubercles are 

 very indistinct ; the antennae have the second and third joints short and of equal length, 

 the three basal joints are pale, the others obscure and dark fulvous ; the elytra show no 

 impression below the base, and the punctuation can only be seen under a very strong 

 lens. The specimen from Aceytuno is larger, of a paler colour, and the lateral margin 

 of the thorax has a piceous spot ; other differences I cannot find, and believe, therefore, 

 both insects to represent the same species. 



10. Aphthona pallidipennis. 



Below black ; above testaceous ; head and thorax fulvous, impunctate ; elytra entirely impunctate, the suture 



narrowly obscurely piceous.
