342 PHYTOPHAGA. 



2. Pseudoepitrix vittatipennis. (Tab. XX. fig. 23.) 



Black; head and thorax pale fulvous; the latter punctured at the base only; elytra punctate-striate, a longi- 

 tudinal stripe from base to apex on the disc of each elytron flavous. 



Length 1 line. . 



Head impunctate, obsoletely grooved round the inner margin of the eyes ; labrum and palpi black ; antennas 

 nearly as long as the body, black, the third and fourth joints equal in length ; thorax slightly wider than 

 long, narrowed at the base, the surface impunctate, except within the transverse basal groove, which is 

 distinctly punctured, and extends across to the lateral margin ; elytra rather finely and regularly punctate- 

 striate towards the suture, more strongly near the lateral margin, the apex nearly impunctate ; between 

 the shoulder and the suture is a narrow but regular longitudinal yellow stripe, which extends from the base 

 to a little distance from tbe apex, where it curves round towards the suture ; this band occupies the space 

 of the third interstice ; entire underside and legs black. 



Hab. Panama, Volcan de Chiriqui (Champion). 



This species has still more the appearance of a small Lema, owing to the constriction 

 of the thorax at the base and the square-shaped base of the elytra; the latter are 

 without hairs ; the thoracic groove is perhaps rather more distinct than in the preceding 

 species, but the eyes are accompanied by a similar groove. Half a dozen specimens were 

 captured. 



CEEPIDODERA. 

 Crepidodera, Chevrolat in d'Orbigny, Diet. Univ. Hist. Nat. iv. p. 334 (1844). 



At present this genus is not particularly well defined ; it contains species which, 

 probably, will eventually have to be placed in separate genera for the sake of a more 

 clearly defined characteristic of Crepidodera proper, if such is possible ; but here, as 

 well as in other genera, we find intermediate and doubtful structural characters. In 

 the genus under consideration, those species of Halticintfi are placed which, in 

 connexion with closed anterior coxal cavities, have a thoracic transverse basilar groove, 

 generally, but not always, limited at the sides by a perpendicular depression, and 

 punctate-striate elytra. Although the genus seems to be represented in nearly all 

 parts of the world, no species have up to the present been described from Central 

 America ; but few specimens, of four or five species, are before me. 



1. Crepidodera chiriqiiensis. (Tab. XX. fig. 25.) 



Fulvous ; antennEe and legs black ; head and thorax impunctate ; elytra finely punctate-striate. 



Length \\ line. 



Head obliquely grooved between the eyes; frontal tubercles strongly raised, oblique ; lower part of the face 

 and the labrum testaceous ; apices of the mandibles black ; palpi very slender, testaceous ; antennae half 

 the length of the body, black, apex of each joint furnished with a few stiff hairs, third and fourth joints 

 equal ; thorax transverse, anterior margin straight, posterior margin slightly rounded at the middle, the 

 sides rather evenly rounded, straight at the base, anterior angles obtuse, furnished with a single hair, 

 basilar groove deeply impressed and bounded at the sides by an equally well-marked longitudinal groove, 

 Burface entirely impunctate ; elytra slightly widened towards the apex, rather distinctly transversely 

 depressed below the base, surface regularly punctate-striate, the apex nearly impunctate ; underside and 

 the base of the femora fulvous ; legs and apices of the femora black.
