544: PHYTOPHAGA. 



D. beata, Baly, exactly resembles this species in coloration and shape and also very 

 nearly in the sculpture of the elytra ; but in D. beata the male is devoid of the frontal 

 excavation, and the second joint of the antennae is described as " compressed." In the 

 male of D. ventricosa the basal joint of the antennae is elongate but widened towards 

 the apex; the second joint is short, but not globose or thickened; and the third joint 

 is twice the length of the preceding one, and much shorter than the fourth. The 

 elytra are more deeply sulcate and costate than in D. beata, and have the flavous bands 

 somewhat thickened or raised ; of the two basal spots the outer one is small, but the 

 spot near the scutellum is nearly round and large ; the narrow flavous apical margin 

 does not extend upwards from the apex, and in this respect, as in all others regarding 

 the coloration, D. ventricosa agrees entirely with D. beata. 



Found in abundance at Bugaba. 



95. Diabrotica bifasciata. (Tab. XXXII. fig. 23.) 



Ovate, widened posteriorly, black, the head, antennae, thorax, and legs, pale fulvous; thorax obsoletely bifo- 

 veolate ; elytra closely punctured, black, a transverse band at the middle and another near the apex, 

 flavous. 



c?. Head deeply excavated in front; the first joint of the antennae slightly dilated at the apex, the third 

 joint curved. 



Length 3 lines. 



Head impunctate, deeply excavated in front ; antennae two thirds tho length of the body, flavous or testaceous, 

 the eighth and ninth joints slightly darker, the third joint four times as long as the second and curved at 

 the base, the fourth and following joints gradually shorter; thorax twice as broad as long, the sides 

 narrowed near the base, the surface with an obscure fovea on each side, impunctate ; scutellum black ; 

 elytra rather convex, widened posteriorly, closely and distinctly punctured, black, a transverse band at 

 the middle (of half the width of the black portion), and another band near the apex (neither band 

 extending to the extreme lateral margin), flavous.

^ D. bifasciata is larger than D. lepida ; the elytral bands are straight and more 



regular, and wider; the thorax is less distinctly impressed; and the antennae are 

 differently formed. The female has no frontal excavation, and the antennae in this 

 sex have simple joints. 



Found in abundance on the slope of the Volcan de Chiriqui, more rarely at Bugaba. 



96. Diabrotica funesta. 



Black, the apical four joints of the antennae, the thorax, the anterior femora, and the posterior legs, testaceous ; 

 elytra black, scarcely punctured, a transverse band at the middle, and the apices, yellowish-white. 



Length 3 lines. 



Head black, impunctate, the clypeus with a strongly raised central ridge ; antennae two thirds the length of 

 the body, the third joint more than twice the length of the second and as long as the fourth, the apical 

 four joints pale testaceous, the extreme apex of the terminal one black; thorax rather more than one 

 half broader than long, yellowish-white, shining, impunctate, the disc obsoletely transversely depressed ; 

 scutellum black ; elytra with some very fine double rows of punctures, obsoletely sulcate and costate, a 

 narrow whitish transverse band not quite touching either margin on the middle of each, the. apex 

 occupied by a triangular transverse band of the same colour ; underside black ; the anterior legs black,
