posterior pair very stout and long, femur and tibia each about 10 lines; 
anterior pairs much smaller; anterior and intermediate cox: armed with a 
large light-fulvous spine; the upper surface of all femora whitish with a 
reddish tinge, smooth, each having three longitudinal lines of short dark- 
brown diagonal streaks on the outer, and two lines on the inner side, but on

latter pair is also sulcated on the lower side and black at the lower end, and 
bears five spines on the outer and six smaller ones on the inner edge, each 
row gradually increasing in size downwards; posterior tibia very stout, | 
dark brown, triangular, four large spines on the outer and five on the inner 
edge, and five spines together at the lower ends; anterior and intermediate 
tibiæ 7 lines long, brown, each having five pairs of spines on the lower edge, `

Obs. This is both a peculiar and pretty species, something dapper and 
taking about it, from its many and bright contrast colours ; the dark mark- 
ings on the light ground of the prothorax are symmetrical and curious, and 
closely resemble a 6-angled shield with its two supporters! Hence its 
trivial name. It seems allied to D. (or Hemideina) megacephala, Buller ; 
and possesses characters belonging to those two genera,—if they are really 
and naturally distinct, which I doubt.
