24, DiscocEPHALA SORDIDA. 
Sordide flavescens, elliptica, fusco densissime punctata ; caput thoracis 
latitudine sat angustius; thorax linea transversa impressa, lineolis 
duabus obliquis pallide flavis. 
Dingy greenish, elliptical, shining, nearly flat, thickly and irregularly 
brown-punctured, the brown hue forming patches here and there. Head 
much broader than long, about two-thirds of the breadth of the thorax, 
rounded in front. Antenne blackish, less than half the length of the body ; 
tips of the joints pale testaceous. Thorax with a transverse impressed iine, 
between which and the hind border there are two pale yellow smooth lines, 
which diverge hindward. Scutellum almost two-thirds of the length of the 
abdomen, with pale yellow points along each side, narrow towards the tip, 
which is pale yellow and rounded, Pectus and under side of the abdomen 
black. Legs pale yellow, short, stout, black-speckled ; femora incrassated. 
Fore wings mostly brown in the disk; membrane brown, with a curved pale 
yellowish band. Length of the body 4 lines. 
It has much resemblance to D. umbraculata, but in the latter the fore 
part of the head is slightly narrower, the thorax has no oblique lines, the 
scutellum is broader towards the tip, and the abdomen beneath has ouly a 
black stripe.
