318 PHYTOPHAGA. 



Melsheimer's description. The species is comparatively easy to recognize by the absence 

 of the submarginal black elytral stripe. I cannot however, quite understand what 

 Melsheimer meant in describing the elytra as " much, finely, and profoundly punctured." 

 The elytra in my specimens are nearly impunctate or in others very finely punctured. 



CiEPORIS. 



Cceporis, Clark, Journ. of Ent. ii. p. 398; Dejean. Cat. 3 ed. p. 411. 



The only Central-American species described by Clark seems to want the principal 

 character which distinguishes the other species of this genus, that is, the spine at the 

 end of the tibiae, which in nearly all Halticinae is confined to the posterior tibia only, 

 while in Cceporis it is common to all. The three known other species have been found 

 in South America. 



l. CsBporis subcostata. (Tab. XIX. fig. 10.) 



Ceeporis subcostata, Clark, Journ. of Ent. ii. p. 399 \ 



Hab. Mexico 1 . 



As already remarked above, this species lacks the spine at the anterior tibiae, as proved 

 to me by the specimens contained in my collection, and ought perhaps to be placed in 

 Disonycha, with which it agrees in all essential points. The thorax has several rather 

 deep depressions at the sides and at the disk, and has three small piceous spots in one 

 of my specimens, but not the markings as described by Clark. The author, although 

 giving the name of subcostata, makes no mention of any costae of which distinct traces 

 are to be seen at the elytra, the latter having an opaque and finely rugose appearance. 



PELONIA. 



Pelonia, Clark, Journ. of Ent. ii. p. 399. 



The species constituting this genus are insects of graceful shapes and, for the most 

 part, delicate colours, which are generally opaque instead of metallic. The antennae are 

 slender and filiform, and the claws simple. The elytra have a peculiar opaque and dull 

 appearance, with a finely granulate surface. The insects seem to be rare in collections, 

 and none have been previously recorded from Central America, from which country I 

 have four species now before me. 



l. Pelonia elegantula. (Tab. XVII. fig. 25 ; Tab. xix. fig. 7.) 



Pelonia elegantula, Baly, Trans. Ent. Soc. 1879, p. 240 \ 



Hab. Mexico, Tuxtla; Guatemala, San Geronimo (Champion); Panama, Volcan de 

 Chiriqui, Bugaba (Champion). — Peru 1 . 



A good number of this species have been obtained at Panama ; they all differ rather 

 in colour and size from the only type specimen, contained in Mr. Baly's collection, 

 and it is therefore quite possible that they represent another, but very closely allied
