LONGICOUN COLKOPTKHA Ì-K()M SIMATRA S7 



distinct varieties of this sj)ecies occur. In one {vai', blnotata) the 

 white markings of the elytra are gn^atly reduced in size , bein^- 

 represented only by one or two small spots on each elytron 

 between the middle and apex: in the otlier {var. obscura) the 

 elytra are altogether devoid of whit(> spots.

Hab. Engano I. (Modigliani). 



This form is very closely allied to R. alboplagiata, (littering 

 only ill the position and arrangement of the white markings on 

 the elytra. These markings take the form of two dorsal i)ands 

 and one lateral running along th(^ middle tliird of each elytron. 

 In one of two examples, the dorsal bands spread out and unite 

 anteriorly forming a transverse patch which extends towards the 

 suture.

Black, covered with short dark brown pubescence. Elytra ^^■ith 

 a greyish })ul)r'scence covering the suturai region from near the 

 base up to a little past the middle. Head sparsely, and prothorax 

 somewliat densely punctulate. Elytra tliickly and rather strongly 

 punctured , eacli with a sliort fee])ly raised costa near the base 

 and a somewhat longer one l)ehind the middle. In the male, tlie 

 stridulating area of the mesonotum is very finely striate in front 

 and rather coarsely near the Ijase ; this character is not, however 

 ])eculiar to this species, l)eing met with in others of the genus, 

 though not in all.
