PELONIA. 319 



species. The difference in the Central-American insects consists in the much more 

 narrow fulvous sutural and lateral margin, and in the colour of the tibiae, which in 

 nearly, but not all cases, is fulvous instead of black ; the elytral punctuation is also 

 somewhat more remote than in the type. I have, however, specimens before me which 

 approach the latter more closely in colour, and I believe therefore that the species is a 

 rather variable one. 



Some specimens from the same locality have entirely metallic blue elytra, and are 

 larger than most of the others ; but as they do not differ in any other way, I prefer to 

 look upon them as varieties. The figured specimens are from Chiriqui. 



2. Pelonia clarki. (Tab. XIX. fig. 9.) 



Below flavous ; above obscure testaceous, opaque ; sides of the thorax and two longitudinal bands, connected 

 before and behind the middle of the elytra, obscure fuscous. 



Length 1| line. 



Head with a distinct longitudinal ridge at the vertex ; the frontal tubercles strongly raised ; antennae half the 

 length of the body, moderately robust, dark fulvous, fourth joint distinctly longer than the third; thorax 

 narrowly transverse, all its sides straight, surface slightly excavated at each side, the excavation limited 

 laterally by a short ridge, disk finely punctured, pale testaceous, a longitudinal band at each side from 

 base to apex fuscous ; elytra very finely granulate-punctate, of the same colour as the thorax, each elytron 

 with a subsutural and sublateral fuscous band, which join each other at the middle and near the apex. 



Hab. Guatemala, Teleman (Champion). 



This little species seems closely allied to P. rufo-testacea, Clark, from which it differs 

 in its elytral pattern and pale general colour as well as smaller size. The two speci- 

 mens before me do not quite agree, however, in the elytral design, which in one of 

 them has the lateral band extending to the apex, while in the other it is abbreviated ; 

 the subsutural band is narrowed in two or three places, of which the figure will give a 

 better idea. The species is altogether of a very dull opaque appearance. 



3. Pelonia balyi. (Tab. XIX. fig. 8.) 



Below flavous; antenna, knees, tibiae, and tarsi black; head and thorax rufous; elytra obscure dark fuscous, 

 opaque, the sutural and lateral margin flavous. 



Head with a short central ridge at the vertex; clypeus acutely raised; antennae black, the fourth joint the 

 longest and much longer than the third joint; thorax transversely subquadrate, the sides straight, surface 

 finely granulate, opaque, with an oblique raised ridge at each side extending from the posterior angle to 

 some distance below the anterior margin ; scuteUum flavous ; elytra opaque, finely granulate, covered with 

 numerous smooth punctures upon the darker portion, the latter of a purplish fuscous colour, the lateral 

 and sutural margin very narrowly flavous ; underside and femora of the same colour, the knees, tarsi," and 

 tibiae black. 



Hab. Panama, Bugaba (Champion). 



This species somewhat resembles in colour P. vittata, Clark, from which it differs in 

 the narrow flavous lateral margin of the elytra and in the much broader darker portion 

 of the latter. A single specimen only was obtained.
