302 Descriptive Catalogue [1896. 



Graphipterus amabilis, Bohem., 

 Ofvers. Vet. Ac. Forh., 1860, p. 7. 



G. Andersoni, Chaud., Bull. Mosc, 1870, p. 319. 



Head broad, with two lateral whitish or yellow bands joining in 

 the anterior part, the three first joints of the antennae and the basal 

 part of the fourth, red ; prothorax broad, short, with the outer 

 margin slightly serrated, densely covered with more or less yellow 

 hairs and having a broad median longitudinal black band ; elytra 

 elongato-quadrate, hardly ampliate in the middle and with the 

 humeral angles rounded, the outer margin serrulate, covered with 

 greyish white or sometimes yellow hairs with a broad cinnamon 

 band on each side of the disk, and a broader sutural black band 

 slightly acuminate at the apex, being the continuation of the pro- 

 thoracic band ; legs black, sternum and lateral parts of abdominal 

 segments with dense white hairs. Length 13-18 mm. ; width 

 6-8 mm. 



Hah. Ovampoland, Zambezia (between the Limpopo and Zambeze 

 Elvers) . 



In the examples from the last-named locality, the colour of the 

 hairs forming the background is much more yellow than in the 

 specimens from Ovampoland (Cunene Eiver), in which the cinnamon 

 discoidal band turns also sometimes to light brown. 



The G. Anclersoni, Chaud., which differs from G. amabilis, in 

 having a narrow prothorax and less ampliated elytra, is for me the 

 male of amabilis. A collector is always given to securing the larger 

 specimens, because they are more easily seen. I have seen two 

 more males from the Cunene Eiver, caught at the same time and in 

 the same locality. They have the exact shape oiAndcrsoni, with the 

 same paler colouring mentioned above. 



As Mons. E. Oberthur has very kindly placed one of De Chaudoir's 

 examples of Andersoni at my disposal, there can be no error as to 

 the identity of the two species. 



Graphipteeus gratiosus. 

 Head moderately broad, with two lateral yellow bands uniting in 

 the anterior part, the three first joints of the antennae red ; pro- 

 thorax short, with the outer margins serrulate, densely covered with 

 yellow hairs and having a broad median longitudinal black patch ; 

 elytra gradually ampliated from the base to long past the middle 

 without any humeral angle, outer margins serrulate, clothed with 

 rich yellow hairs and having a very broad cinnamon dorsal band, 

 broader in the anterior part, and a sutural black band, slightly 

 acuminate at the apex ; legs black ; sternum and sides of abdomen 

 with dense white hairs. Length 14 mm. ; width 7 mm.
