476 PHYTOPHAGA, 



l. Cleophes unifasciata. (Tab. xxv. fig. 20.) 



Reddish fulvous ; the three apical joints of the antennae, and the posterior femora, piceous ; thorax finely 

 punctured ; elytra finely punctate-striate, reddish fulvous, with a narrow transverse black basal band. 



Length 1| line. 



Head with a few fine punctures, the eyes large, the frontal tubercles very obsolete ; the anterior portion of the 

 face rather long, testaceous ; antennae half the length of the body, pale fulvous, the three apical joints 

 black, the third and fourth joints slender, elongate, and of equal length and each rather more than twice 

 the length of the second ; thorax more than twice as broad as long, the sides slightly rounded before the 

 middle, the anterior angles oblique, the surface with a very obsolete transverse depression near the base, 

 finely and distantly punctured ; scutellum fulvous ; elytra with a distinct depression below the base, 

 regularly and finely punctate-striate, the punctuation scarcely finer and distinct at the apices, and with a 

 narrow black transverse band (extending to the margins and as far as the depression) at the base ; 

 posterior femora not extending to the apices of the elytra ($'?); posterior tibiae deeply longitudinally 

 channelled, the margins of the groove armed with a row of distinct teeth, the inner apices armed with a 

 single stout spur ; claws appendiculate. 



Bab. Panama, Bugaba (Champion). A single specimen. 



Subfam. GALEBUCIN^J. 



This subfamily, although not quite so strongly represented in genera as the " Halti- 

 cinse " (which remark applies to most other parts of the world, as well as to the 

 country under investigation), yet forms no inconsiderable portion of the Phytophagous 

 Coleoptera ; and it is perhaps worth noticing that we usually find amongst the 

 " Galerucinae " greater numbers of individuals of certain species than amongst the pre- 

 ceding subfamily. We find, for example, that the genus Diabrotica, whose metropolis 

 is the entire southern part of America, and extending to North America, is not only 

 exceptionally rich in species, but that some of these are represented by such numbers 

 of individuals, judging from the immense amount of material obtained, that they must 

 swarm in the localities they inhabit ; the same may be said of the genera Monocesta, 

 Galeruca, and others. It is, however, possible that owing to the absence of saltatorial 

 power in the " Galerucinae," possessed to such a great degree by the closely allied 

 " Halticinae," the former fall a more easy prey to the collector, and that their 

 superiority in point of numbers is more apparent than real. The only character of 

 distinction between the Halticinae and Galerucinae which one can point out, is 

 the want of the incrassation of the posterior femora in the latter. From Central 

 America about sixty species of Galerucinae have been described ; the researches of 

 Mr. Champion, Herr Hoge, and others have, however, now added very many new and 

 interesting forms.
