Black, somewhat opaque on the upper side, head either with an 

 elongated pale fulvous patch extending to half the length of the 

 clypeus, or entirely without it; prothorax with nine whitish or 

 yellowish patches, which are occasionally coalescing and thus cover 

 the greatest part of the surface, hut are also entirely wanting in some 

 examples ; scutellum also with or without a flavescent patch ; elytra 

 with a supra-marginal white or flavescent band which is not unseldom 

 either completely or partially obliterated ; in several examples, the 

 background or the intervals of the discoidal part is somewhat 

 brownish red ; pygidium with two white patches ; clypeus and head 

 moderately deeply punctate, palps and antenna' piceous black; 

 prothorax strongly narrowed laterally in front, diagonally ampliated 

 the apex to about the middle, very strongly sinuate there, 

 widest along the base which is straight and fits so closely along the 

 elytra that the mesothoracic epimera are partly hidden, the surface 

 is covered with rough sub-contiguous punctures separated by thin, 

 irregular walls; elytra elongated, very little sinuate laterally, nar- 

 rower at apex than at base, plane, and having on the discoidal part 

 six distinct costac, including the suture, these costae as well as the 

 intervals and the supra-marginal part are coarsely punctate ; 

 pygidium vertical, and having along the apical margin a fringe of 

 small black hairs ; abdomen glabrous, pectus and legs sparsely 

 punctate, the punctures briefly setigerous, the hairs black ; antenme 

 and palpi piceous red, the club equal in length in both sexes. 



The type form of -V. albonotata was described from an example 

 with nine white macules on the prothorax, and a white supra- 

 marginal band and a patch on each side of the apical part on each 

 elytron, the latter being black ; 31. jucunda was described from an 

 example in which the patches on the thorax are light fulvous, instead 

 of white, and have invaded nearly the whole surface; the intervals 

 of the elytra are rufescent. But the colouring is very variable. 

 According to Mr. G. A. K. Marshall, this species is termitobious, 

 never seen on gum or flowers, and flies in the sunshine. 



Length 16-20 mm. ; width 8J-9i mm.
