Brunnea; vittis duabus in thorace (prima laterali, secunda 
infra lata post oculos), in elytris vittis duabus decussatis, 
magnam literam X formantibus, tertiaque parte apicali 
suture, femoribus posticis ad apicem maculis duabus cor- 
poreque infra (medio excepto) albidis ; mandibulis, clypeo et

Brown. Head convex on the forehead, truncated obliquely 
below, marked behind with five lines and with a longitudinal 
narrow channel which borders the eyes. Mandibles brilliant 
black. Labrum pilose, square. Clypeus very ciet trans- 
verse. Eyes large, slightly emarginate above, black. Antenne 
hardly reaching more than two-thirds of the ES of the 
body, tolerably thick, with the last article acuminate. Thorax 
straight in front and behind, marked with three transverse 
channels ; four white longitudinal dorsal tubercles two lines in 
length, the first on the side, and the second omnis facing the 
eye; lateral spine very stout and sharp. tellum semi- 
circular. Elytra broader than the thorax, seals on the shoul- 
der, and depressed within it, parallel and rounded towards the 
apex of the suture, which is slightly angular; they have two 
white bands crossed in the form of an X, and of which each 
starts obliquely from the shoulder to the dedita of the suture, 
and thence proceeds backwards obliquely to the margin, which 
it reaches at the level of the apex of the posterior thigh ; at that 
place it bends back in a semicircle towards the extremity, and 
remounts on the suture, where it terminates below the union 
i of € lines. Legs and middle s the body of an ashy brown.
