NEOBEOTICA. 579 



stripe extending from the middle of the base to the suture at the middle and from there at nearly right 

 angles to the lateral margin, and another small obliquely curved stripe near the apex of each, the latter 

 extending from the suture to the apical angle, and forming (with the corresponding stripe on the other 

 elytron) a ring-shaped mark ; underside, tibiae, and tarsi black, the femora fulvous, with a small blackish 

 spot ; claws appendiculate 5 the anterior coxal cavities open. 



Eab. Mexico, La Parada (Salle). 



I have only seen a single male specimen of this curiously-marked insect, which 

 resembles in several respects certain species of the genus Cerotoma. 



19. Neobrotica modesta. 



Testaceous, the head, the intermediate joints of the antenna?, and the tibiae and tarsi black ; thorax impunctate, 

 pale fulvous ; elytra finely punctured and obsoletely costate, a spot at the shoulder (sometimes absent) 

 black ; breast piceous. 



Length 2|-3 lines. 



Head not visibly punctured ; the frontal tubercles indistinct, bounded behind by a deep fovea ; antennae with 

 the basal two and the apical three joints testaceous or flavous, the rest black, the third joint scarcely 

 shorter than the fourth ; thorax one half broader than long, the disc impunctate, with a deep transverse 

 sulcation not extending to the sides ; scutellum testaceous ; elytra closely and irregularly punctured, the 

 interstices obsoletely longitudinally costate, more distinctly so at the sides than on the disc, the shoulders 

 with a black spot. 



Eab. Mexico, Tuxtla (Salle). 



Two specimens ; one of these is smaller than the other, and has the humeral spot 

 obsolete, and the breast scarcely darker than the rest of the under surface. 



20. Neobrotica undecim-maculata. 



Testaceous, the head, the intermediate joints of the antennae, the tibiae, tarsi, and breast black ; elytra finely 

 punctured, and obsoletely longitudinally sulcate, three spots at the base, four at and four others below the 

 middle, placed transversely, black. 



Length 2| lines. 



Hal. Mexico, Jalapa (Edge). 



N. undecim-maculata agrees with Diabrotica spilota, Baly, in the colour and markings 

 of the elytra, but is separated from that species by the generic characters. The 

 antennae have the third joint slightly shorter than the fourth ; the thorax is impunc- 

 tate, and of the usual shape and sculpture ; of the three basal spots on the elytra the 

 central one surrounds the scutellum, the other spots being placed transversely in pairs 

 near and below the middle. 



21. Neobrotica melanocephala. (Tab. XXXIII. fig. 14.) 



Head, the intermediate joints of the antennae, the tibiae, tarsi, and breast black ; thorax fulvous, deeply sulcate ; 



elytra finely geminate-punctate, fulvous, the basal and sutural margins anteriorly, and a narrow lateral 



stripe from the base to the apex, black ; abdomen testaceous. 

 Length 3 lines. 

 Head entirely black, with a deep fovea between the eyes ; antennae nearly two thirds the length of the body, 



the basal two and the apical three joints fulvous, the rest black, the third joint as long as the fourth :
