330 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
an impression across it behind the projecting epistome. "Thorax transverse, broader than 
' long, with the apex slightly emarginate, broadest before the middle, narrower and 
slightly sinuated behind, rounded in front, narrower behind than in front; anterior 
angles rounded, posterior angles approaching to right angles, but the point is obliquely 
cut off and obtusely rounded; punctate; base bisinuate, truncate. Scutellum broad, 
transverse, semicircular. Elytra at least a half longer than the thorax, about one-third 
wider, the base straight, and the shoulders prominent close to the humeral angles, 
which are rounded; sides nearly parallel, almost straight, declinate; there is a longi- 
tudinal depression inside the shoulders, and the suture is slightly depressed; subcostate, 
the costze slightly sinuate, the interstices faintly punctate somewhat irregularly in rows; 
exterior apical angles slightly rounded, nearly straight, sutural angles nearly right 
angles. Abdomen rather thickly punctate, darker than the other parts of the body; 
pygidium flavous. Body below testaceous. 
Believed to be from Brazil. I received a single specimen many years ago among a 
number of Brazilian insects, and I have never seen a second. Now in the British 
Museum.

third shorter, fourth longest, cylindrico-conical. Ligula broad, with a short, semiovate 
membranous lobe placed obliquely in front on each side. Labial palpi stout, with the 
first article small, the second and third rather stout, subovate, nearly equal. Prothorax 
subdepressed, broader in front than behind, and narrower at the base than the elytra.
