moderately large. The prosternum is extremely short, not longer- 

 than the mesosternum ; between the coxas it appears as a concave 

 lamina scarcely longer than its width behind, with a continuous- 

 elevated margin except at its line of contact with the mesosternum, 

 and somewhat narrowed to the front, where it is rounded. The 

 mesosternum is much like that of Orcus in size and shape, but is 

 a little more convex ; its front is truncate, or almost convex. 

 There is a well-defined sixth ventral segment, and the basal ven- 

 tral suture is not less marked than the others. The epipleuree 

 are moderately wide and horizontal at the base, but become 

 gradually narrower and vertical, disappearing altogether before 

 the apex ; they are not foveated. The femora and tibia3 are all 

 strongly compressed, the former being deeplygrooved for the reception 

 of the latter. The tarsi are very stout. The abdominal lamellae are 

 complete, and extend back about two-thirds the leng-th of the 

 basal ventral segment. The prothorax is not narrower at its 

 base than the true base of the elytra, but the latter dilate very 

 rapidly immediately from the base, and the humeral angle is so 

 slightly marked that until carefully examined the anterior part 

 of the lateral margin might pass for a portion of the base.

A very pretty Scymnid, the red markings being very bright 



and sharply defined. On each elytron they are as follows : — 



(o) A vitta parallel and near to the suture, extending from the 



base about four-fifths of the distance to the apex, very wide in 



front and quickly narrowed (somewhat resembling a dumb bell 



with one of the knobs broken off') ; (fi) a vitta occupying the front 



half of the lateral margin, and dilated at its base so as to meet 



the sutural vitta about the middle of the base ; (c) a large discal 



spot just behind the middle ; {d) an apical spot. The red parts 



of the epipleur?e correspond with the marginal and apical red 



portions of the upper surface. This species does not appear to 



differ structurally from Lindi in any respect, and its sculpture is 



very similar. Apart from the totally different coloration it is a 



larger and more convex insect.
