but with much finer and very indistinct striae. Rows of 

 shining granulations are situated on a rudimentary stria 

 by the side of the scutellum and on the first stria which 

 runs along the suture. The following striae only have a 

 few granulations at the base. The pubescence of the ely- 

 tra is of an equal yellowish color on which dark patches 

 are visible greatly varying according to the individuals. A 

 large patch is always present close to the suture a little 

 behind the middle and sometimes sends out a branch which 

 unites it to another spot on the lateral margin of the ely- 

 tra. This lateral spot is preceded by two others and fol- 

 lowed by one or two smaller spots towards the extremity 

 of the elytra. Along the suture the spots are rather 

 regularly square and the remaining portion of the surface 

 of the elytra is strewn with irregular dots. 



Under surface smooth, the sides of the abdomen with a 

 large dark spot at the base of the segments. 



Legs clothed in the same manner as the body. Femora 

 with a large smooth and glossy very conspicuous brownish- 

 red space at the base. 



A single female specimen was captured in the dis- 

 trict of Rawas (Sumatra) , during the Scientific Sumatra- 

 Expedition, in May 1878. Others from Java are in my 

 possession.
