4tS8 Mr. B. P. Uvarov—^ Revision of 



2 a. Anacridium moestum mcestum (8erv.). 



1839. Acridmm uioRstum, Serville, Ins. Orth. p. 654. no. 14. 

 1910. 0[rthacanthacris] mcesta, Kirb}^, Cat. p. 444.no. 1. 

 **1907. 0\j'that^anthacris] wernerella, Karny, Sitz, Akad. Wlss. Wien, 



cxvi. Abt. 1, p. 305. no. 57. 

 1918. Orthacanthacris eximia, Sjostedt, Arkiv Zool. xii. no. 1, p. 2, 



fig. 2. 



The characters given by Karny for separating his 

 wernerella from mcestum are not of specific value, as may be 

 easily seen in a sufficiently long series of specimens. 



The base of the hind wings is sometimes rosy or violaceous. 



Geographical distribution. This subspecies is distributed all 

 over South Africa, ranging northwards up to North Uganda 

 (Gondokoro) and Northern Nigeria (Zungeru, B.M.) ; it 

 has, however, never been recorded from the forest-regions of 

 Central and West Africa, and it seems that it does not 

 penetrate there. * 



2 h, Anacridium mcestum melanorhodon (Walk.) . (Fig. 6 c.) 



**1870. Acridmm 7nelanorhodon, Walker, Cat. iii. p. 585. no. 28. 

 **1907. [O. wernerella], var. sphalera, Karny, Sitz. Akad. Wiss. Wien, 

 cxvi. Abt. 1, p. 305. 

 1907. Acridium cBthiopicum, Finot, I. c. pp. 269, 346. 



The characters separating this form from the typical 

 moestum are of such a kind that I cannot give them specific 

 value, and the data concerning their distribution lead to the 

 conclusion that they are but geographical races of the same 

 species. 



Geographical distribution. The race melanorhodon , originally 

 described by Walker from St. Jago, Cape Verde Islands (not 

 S. America, as incorrectly recorded by Walker), represents 

 a northern form of moestum. 1 have seen examples from 

 St. Vincent, Cape Verde Islands ; Khartum ; Massowah ; 

 Aden and Sokotra ; Karny described his sphalera from Renk, 

 Sudan, and Finot^s (Bthiopica was described from Abyssinia. 



3. Anacridium jiavescens (F.). 



1793. [Gri/llus] Jiavescens, Fabricius, Entom. Syst. ii. p. 52. no. 24. 

 1910. Olrfhacanthacris] Jiavescens, Kirby, Cat. p. 445. no. 10. 

 **1870. Acridium pardalinum. Walker, Cat. iii. p. 587. 



The identity of pardalinum^ Walk., with Jiavescens, F., 

 has been recorded already by Kirby in the ' The Fauna of 

 British India' (Acrid, p. 225, 1914), and is beyond any 

 doubt. 



Geographical distribution. The only known localities where 

 this species occurs are Tranquebar (Fabr. /. c), Trichinopoly
