Body elongate. G-eneral colour shining brown with black 

 marks on the head and pronotum and with a pattern on the 

 elytra, as follows : a large ill-defined patch on the vertex of the 

 head ; on the pronotum a group of three roundish marks situated 

 in the middle, of which the single hindmost one is obsolescent ; 

 scutellum black ; elytra, on a general ground-colour of dark red- 

 brown there is a pattern of patches of light brown, several of 

 which assume definite shapes, enclosing in their centres smaller 

 dark brown patches ; on each elytron, parallel to the suture, a 

 longitudinal series of five, the first close to the suture at the base 

 and behind it the second, which is larger and has an obsolescent 

 elongate, dark streak in the centre, and which, expanding in 

 front, forms a loop joining the first in a broad patch which covers 

 a certain part of the basal area ; the third, an oval patch, is 

 situated behind the second ; the fourth is at that point where ihe 

 elytron slopes down towards the apex, it encloses a dark brown 

 patch, is more or less pointed at the posterior end, sending off 

 an erect arm from its front end ; the fifth is at the sutural angle ; 

 the humerus is dark red-brown ; from the humerus to the post- 

 median area there is a large and elongate lighter yellow patch 

 which extends right to the margin and along it to the anterior 

 lateral angles of the elytron ; this large light area contains three 

 red-brown patches, the hindmost of which is the largest, all 

 being situated within the last but one row of punctures ; and 

 finally, on the bend of the elytron towards the apex, is a pear- 

 shaped patch enclosing a red-brown one in the middle. Underside 

 uniformly bright brown. The colour-scheme may be either 

 considered as produced by an inclusion of red-brown colour on a 

 lighter background or vice versa. 



Head broad, with vertex convex, finely punctate ; interantennal 

 space with a deep semicircular channel separating the epistome 

 from the rest of the surface ; eyes convex. Antennae extending a 

 little distance beyond the base of the pronotum, slender, sparsely 

 covered with hairs, black except the underside of the four basal 

 segments ; first segment club-shaped, second small, rounded, third 

 and fourth almost equal to each other, fifth longer than each of 

 the previous ones ; the following segments are elongate and of 

 similar dimensions. Protlwra.v quadrate, almost as long as broad, 

 or about one-half millimetre broader than long, front margin very 

 gently concave, base very gently sinuate on either side, sides 

 almost straight, bending inwards at the anterior and posterior 

 angles, all of which are rounded ; upper surface gently convex and 

 very finely punctate. Scutellum small, triangular, smooth, shining
