560 PHTTOPHAGA. 



136. Diabrotica uniformis. 



Broadly ovate, dilated, black; thorax transverse, obsoletely depressed, flavous; elytra finely punctured, 



testaceous or flavous. 

 Length 2 lines. 



Hab. Nicakagua, Chontales (Janson); Panama, Bugaba, Volcan de Chiriqui 

 (Champion). 



It will not be necessary to give a detailed description of D. uniformis, as it agrees in 

 everything, except as regards coloration, with T). dilatata. In shape it exactly resembles 

 the last-named species ; and the thorax also agrees in every particular, but is flavous 

 instead of black. The large number of specimens (upwards of fifty) before me agreeing 

 perfectly with one another, I am obliged to treat I), uniformis as a distinct species. 

 With one exception, all the examples were obtained in the State of Panama ; the 

 insect, therefore, is of .more southern distribution than D. dilatata. In some individuals 

 the antennae and legs are more or less stained with piceous or testaceous. D. uniformis 

 is on the average smaller and less convex and dilated than the preceding species. 



137. Diabrotica corallina. (Tab. XXXII. fig. 17.) 



Black ; thorax narrowly margined with fulvous, bifoveolate ; elytra reddish-fulvous, closely punctured, and 

 obsoletely rugose. 



Length 2| lines. 



Head black ; antennae black, fulvous at the base, the third joint twice the length of the second, the fourth joint 

 longer than the fifth ; thorax twice as broad as long, the sides straight, narrowly margined with fulvous, 

 the disc black, shining, with a few punctures, and a deep fovea on each side ; scutellum black ; elytra 

 slightly widened towards the middle, narrowly margined, dark reddish-fulvous, closely punctured, the 

 interstices slightly rugose on the anterior portion and nearly smooth towards the apex ; underside and 

 legs black. 



Hab. Mexico, Chiapas (Salle). A single specimen. 



Narrower and more parallel than the preceding species; the thorax black, narrowly 

 margined with testaceous, and the elytra reddish in colour and closely punctured. 



138. Diabrotica luteola. 



Ovate, convex, widened posteriorly, black ; head, antennae (the apical joints excepted), femora, and thorax, pale 

 fulvous ; thorax without depressions ; elytra fulvous, distinctly and subremotely punctured. 



Length 3| lines. 



Head impunctate, entirely fulvous ; antennae scarcely half the length of the body, the apical three joints obscure 

 fuscous, the rest fulvous, the third joint twice the length of the second ; thorax nearly twice as broad as 

 long, narrowed near the base, the surface impunctate, without depressions ; scutellum fulvous ; elytra 

 rather strongly widened posteriorly, the apical portion deflexed, the sides narrowly margined, the surface 

 not very closely but distinctly punctured ; underside and the tibiae and tarsi black, the femora fulvous. 



Hab. Panama, Volcan de Chiriqui (Champion). 



Only a single specimen, evidently a female, was obtained. I), luteola differs from 

 D. sobrina in the colour of the antennae and legs, and in the want of the thoracic 

 impressions and the dark apical margin to the elytra.
