NEOBKOTICA. 573 



detect any other mark of distinction, I treat this specimen as a variety of the present 

 species. N. ornata seems to vary in one or more respects in series of specimens obtained 

 at the same localities. The dilated anterior tibiae and tarsi in the male insect is another 

 distinctive character of this species. 



3. Neobrotica punctatissima. 



Flavous, the base of the head black, the lower part of the head, the antennae, and the thorax fulvous, the latter 

 bifoveolate ; elytra closely and strongly punctured, a ring-shaped mark at the base, and another below the 

 middle, open behind, dark blue. 



Length 2-3 lines. 



Hab. Mexico, Acapulco (Hoge). 



In this species the thorax, instead of having a deep transverse groove as usual in 

 Neobrotica, has two deep round fovese at the sides, these foveae, when seen in certain 

 lights, assuming an oblique shape. N. punctatissima resembles in general coloration 

 and elytral pattern N. ornata, but differs in the thoracic impressions and the very 

 closely and deeply punctured elytra ; the blue ring at the base of the latter is larger 

 than in N. ornata, and its posterior edge is straight ; and the blue mark below the 

 middle is lunate in shape, and open behind. 



4. Neobrotica imitans. 



Fulvous, the head and breast black ; thorax deeply sulcate ; elytra very closely and -distinctly punctured, 

 fulvous, two elongate spots at the base, two others below the middle, and the suture below the seutellum, 

 black. 



Length 2§-3 lines. 



Hab. Costa Rica ( Van Patten). 



N. imitans almost exactly resembles Diabrotica 9-maculata, Jac, and several other 

 closely allied species, in the pattern of the elytra. The elytra may almost be described 

 as " rugosely punctured ; " of the spots or short stripes, the longest is placed at the 

 shoulder ; the other stripes are — a short one near the suture below the base, another 

 below the seutellum at the sutural margin, and two others near the apex, of which the 

 slightly curved outer one is the longest. The thorax is transverse, with the usual 

 deep sulcation. 



5. Neobrotica cseruleo-lineata. 



Testaceous ; thorax deeply transversely grooved ; elytra closely punctured, obsoletely longitudinally sulcate, a 

 longitudinal stripe at the shoulder, another near the apex, two small spots on the disc, and the suture 

 anteriorly, metallic blue. - 



Far. The intermediate joints of the antennae, the vertex, the breast, and the tibia? more- or less piceous. 



Length 3-3| lines. 



Hab. Mexico, Tepansacualco (Salle), Teapa, Tapachula (Hoge); Guatemala, San 

 Isidro (Champion). 



N. cceruleo-lineata resembles Diabrotica fulvicornis, Jac, and several other closely
