450 Mr. J. S. Baly's descriptions of 



Similarly coloured to D. viridipennis, Jac. ; at once separated by 

 the absence of the longitudinal costie on the elytra. 



Dia brotica gi hhosa. 



Late ovata, postice ampliata, valde convexa, nigra, nitida, thorace 

 elytrisque sordide flavis ; thorace transvervso, disco leviter trans- 

 versim depresso, utrinque obsolete foveolato ; elytris gibbosis, 

 crebre rugoso-punctatis. Long. 4 lin. 



Hah. Eastern Ecuador {Buckley). 



Head longer than broad, trigonate ; antenna filiform, the third 

 joint twice the length of the second, nearly equal to the fourth. 

 Thorax nearly twice as broad as long ; sides straight and parallel 

 from the base nearly to the apex, the anterior angle subacute ; disk 

 transversely and slightly depressed, minutely but not closely 

 punctured, obsoletely foveolate on either side. Elytra gradually 

 increasing in height from the base to beyond the middle, then 

 obliquely deflexed to the apex ; surface closely rugose-punctate. 



Diahrotica rugulosa. 



Ovata, postice ampliata, valde convexa, nigra, nitida, femoribus, 

 antennis, thoracis lateribus elytrorumque limbo laterali, pallida 

 prasinis, mesopleuris pube aurea dense vestitis ; thorace lateribus 

 fere rectis, pone medium leviter sinuatis; disco bifoveolato, sub- 

 crebre punctato ; elytris olivaceo-tinctis, rude rugoso-punctatis, 

 vittis nonnullis irregularibus instructis. Long. 4 lin. 



Hah. Eastern Ecuador {Buckley). 



Antennfe slender, filiform, the third joint twice the length of the 

 second; three or four upper joints staiired with fuscous. Thorax 

 broader than long ; sides nearly straight and parallel, slightlj' 

 sinuate behind the middle, narrowly edged with pale grassy green ; 

 disk nitidous, impressed on either side with a large round smooth 

 fovea,- rest of the surface distinctly but not very closely punctured. 

 Elytra strongly convex, coarsely rugose-punctate ; disk of each 

 with four or five irregular raised vittae, which are connected with 

 each other by irregular ridges, and form a network on the surface ; 

 lateral margin narrowly edged with pale grassy green. 



This and the jjreceding sijecies are very similar in 

 form to D. Hebe.
