Graphipterus limbatus, Castlenau, 

 Hist. Nat. Ins., i., 1835, p. 59. 



G. httescens, Chaud., Bull. Mosc, 1843, iv., p. 714. 



G. marginellus, Guer., Eev. Zool., 1859, p. 527, pi. 21, fig. 7. 



G. parvicollis, Chaud., Bull. Mosc, 1843, iv., p. 715. 



Black, thickly covered with yellowish-brown short hairs, turning 

 sometimes to almost light cinnamon or grey, but with the outer 

 margin of the prothorax slightly, and that of the elytra conspicuously, 

 white ; the description of G. cicindeloides applies almost entirely to 

 this species ; the prothorax shaped alike, is, however, a little 

 shorter, the four basal joints of the antennae are also black, but the 

 others are more or less flavescent ; the elytra are of a similar shape, 

 and the fore tarsi of the male are not slightly dilate as in G. cicinde- 

 loides, the size of which is about threefold that of G. limbatus. 

 Length 8-11 mm. ; width 4-5 mm. 



We have in this species a very good example of assimilation of 

 colouring to surroundings. The grey variety, G. lutescens, of 

 Chaudoir, occurs near Cape Town on light greyish, sandy soil, while 

 my brightest yellow examples were captured on the reddish ground 

 of Namaqualand and of the Karoo. 



Hah. The habitat of this species is restricted to the western part 

 of the colony. I have recorded it from Cape district, Stellenbosch, 

 Paarl, Worcester, Carnarvon, Namaqua and Bushmanland, and 

 Kimberley. 



Graphipterus limbatellus, Bohem., 

 (Piezia) Insect. Caffr., i., 1848, p. 97. 



G. imsillus, Chaud., Bull. Mosc, 1852, i., p. 62. 



Pubescence varying from very light grey to pale red ochre, shape 

 and disposition of the whitish marginal bands identical, but the 

 joints of the antennae, with the exception of the three basal joints, 

 are rufescent, and the tibiae almost always red ; the size does not 

 exceed that of the smallest G. limbatus, and for a long time I did 

 identify G. intsillus with G. limbatus, but the constant identity in size 

 of the examples captured at very great distances from one another 

 leads me to consider G. limbatus as a distinct species. Length 7-8 

 mm. ; width 3f-4 mm. 



Hab. The range of this insect is very great. It is found in the 

 Cape Colony (Burgher sdorp, Kimberley), Transvaal (Potchefstroom 

 and Pretoria), Zambezia (Salisbury, Buluwayo), and also in Ovam- 

 poland (Cunene Eiver).
