Genus Furcaspis, Lindinger. 



This genus was erected by Lindinger in 1907 to accommodate the species " biformis " 

 and capensis. The following is a translation of his diagnosis : — ■ 



" Scale of the $ round or elongate, thick, of differing brown colour, arched. 

 Exuviae central or subcentral. 



" Scale of the $ similar in colour and texture but different in shape being narrow 

 and linear with the exuviae at the anterior end. 



" Body wine-red in colour. 



" Pygidium yellow, broadly rounded. Lobes, more than 3 pairs, the innermost 

 3 pairs almost similarly formed, those more removed differing to a greater or less 

 degree, often toothed. Plates branched only at the end, apparently 2 to 3 toothed, 

 the teeth united by a membrane which disappears on the dorsal side, so that the 

 plates are really spoon-like. Design on dorsal side absent (such as found in the genus 

 Pseudaonidia)." 



It should be mentioned that the scale of the two South African species is more 

 or less shell-like, with the exuviae curved over to one side, and with + distinct 

 •concentric ridges on the upper surface of the scale.

Common Name : Aloe Red Scale. 



Scale of adult $ sub-circular or oval, moderately convex, very dense and tough, 

 with the highest point towards one side, from which, as a centre, concentric ridges 

 or corrugations extend to the margin. The first exuviae are laterad again of the 

 highest point and appear as a rounded prominence, thus giving the whole scale 

 the exact appearance of a minute shell. The colour of the scale varies with age. 

 When young it is a rich pale brown, but becomes more reddish later. The most 

 common colour in dry material is dry-blood colour. In living specimens the adult $ 

 scale is sometimes very beautiful, with the margins and first exuviae orange brown, 

 the second exuviae covered with deep red and the concentric ridges very dark, 

 almost black. The average size of the adult $ scale is 2'5 mm. in largest diameter, 

 but occasional specimens reach 3 "5 mm. Ventral scale very dense and tough, 

 yellowish white.
