new Species of Halticine. 321 
Head coarsely rugose ; encarpe and carina ill-defined, the 
lower end of the latter terminating on a strongly raised trans- 
verse ridge; antenne scarcely half the length of the body, 
moderately robust, thickened towards the apex, entirely black ; 
third and fourth joints nearly equal in length. Thorax nearly 
three times as broad as long; sides broadly margined, reflexed, 
straight and parallel, rounded and converging before the 
middle, anterior angles produced, thickened, obtuse; basal 
margin slightly oblique and faintly sinuate on either side near 
the outer angle, the latter produced, acute ; intermediate space 
obtusely truncate, narrowly edged with black; disk finely 
granulose, nitidous, sparingly punctate ; lateral margin con- 
cave, the outer edge thickened. Scutellum trigonate, rather 
broader than long, its apex obtuse. Hlytra broader than the 
thorax, oblong-ovate, moderately convex, finely granulose- 
punctate, subopaque; the white marking nitidous, finely 
punctured. 
Gidionychis nigro-lineata. 
@. ovata, modice convexa, nitida, subtus piceo-nigra, prothorace 
abdominisque limbo exteriore sordide fulvis; supra sordide fulva, 
vertice, scutello antennisque (harum articulis basalibus tribus 
piceis exceptis) nigris; thorace levi, tenuiter, remote punctato, 
maculis quinque, 2 et 3 dispositis, nigro-piceis notato; elytris evi- 
denter, subcrebre punctatis, utrinque linea suturali, vitta sub- 
marginali, apice cum linea suturali conjuncta vittaque discoidali, 
a basi fere ad apicem extensa, nigris. 
Long. 23 lin. 
Hab. Brazil, Bahia. 
Vertex smooth, nearly impunctate, lower portion of front 
coarsely punctured ; encarpe subquadrangular, separated from 
the front by a deep longitudinal groove; antennz robust, 
second and third joints nearly equal in length; labrum and 
jaws obscure piceous. Thorax with its sides broadly mar- 
gined, straight and nearly parallel behind the middle, thence 
rounded and converging to the apex, anterior angles armed 
with a slightly excurved, obtuse tooth ; upper surface nitidous, 
remotely and finely punctured, lateral margin reflexed. Scu- 
tellum trigonate; its apex obtuse, piceous. Hlytra rather 
broader than the thorax, oval, moderately convex, much more 
strongly punctured than the thorax; lateral margin narrowly 
reflexed ; inflexed limb obscure fulvous, its inner edge nigro- 
piceous. Anterior border of prosternum deflexed. Basal 
joint of hinder tarsus nearly equal in length to the following 
two united.
