Dull red, the upper part of the head, the middle of the pronotum, 

 the scutellum, the corium, and the membrane black ; the clavus 

 testaceous ; and the segments of the connexicum often with large 

 dusky markings. Head square, obliquely sloping outwards, with 

 a projecting point laterally behind the eyes, and another projecting 

 on each side in front of the antennae, between which it is tri- 

 angularly narrowed as far as the broad frontal process, which 

 extends beyond this point for about one-third of the total length 

 of the head; it is slightly denticulated at the sides, and slightly 

 bifid at the extremity. Antennoe Avith the four joints all of nearly 

 equal length. Pronotum slightly contracted in front, where it is 

 rounded, and slightly concave in the middle, with slight denticula- 

 tions on the sides in front ; on each side of the median line of the 

 front half is a black, irregularly-shaped space. The greater part 

 of the insect is moderately coarsely punctured ; the spaces between | 

 the veins of the membrane look like large depressed pits. Femora J 

 thickened and, as well as the tibiae, very finely denticulated. Under- ; 



surface varied with black and red. \

 probably includes more than one species), but with the markings ' 

 more clearly defined. i
