Opisthodichrus cochlearistylus Karsch, Berlin. Ent. Zeitschr., XXXVI, p. 87, pi. 2, 

 fig. 4 (1891); Brunner, I. c, p. 32, pi. I, fig. 3 (1895). 



A male from Lolodorf and a female from Batanga are referred to 



this species. The former was collected by A. I. Good and the latter 



by F. H. Hope. C. M. Ace. Nos. 5264 and 5293. 



Genus Liocentrum ICarsch. 



Liocentrum Karsch, /. c, p. 272 (1890). 



This is an African genus based on a species found in Cameroon. 



64. Liocentrum aduncum Karsch? 



Liocentrum aduncum Karsch, Berlin, Ent. Zeitschr., XXXVI, p. 88, pi. 2, fig. 3 

 (1891); Brunner, I. c, p. 32 (1895). 



A female Pseudophyllid from Lolodorf is referred to Karsch's 



Liocentrum aduncum with some misgivings. It apparently has been 



immersed in spirits, has lost its color, and its wings have also become 



somewhat distorted. It was taken February 19, 1914, by A. I. Good. 



C. M. Ace. No. 5264. 



Genus Cymatomera Schaum. 



Cymatomera Schaum, Ber. Akad. Berlin, 1853, p. 777; Ib., in Peter's Reise n. Mos- 

 samb., V, p. 122 (1862); Stal, Recens. Orth., it, pp. 53, 69 (1874); Karsch, 

 Ent. Nachr., XVI, p. 274 (1890); Ib., Berlin. Ent. Zeitschr., XXXVI, pp. 77, 

 96 (1891); Brunner, Mon. Pseudoph., pp. 12, 82 (1895). 



This is also an African genus, which contains several species. From 



the general griseous color of its representatives I should judge them 



to be dwellers on tree-trunks or on the ground among various kinds of 



dead and decaying vegetation, or perhaps on lichen-covered rocks. 



Only one species is at hand. 



65. Cymatomera argillata Karsch. • 



Cymatomera argillata Karsch, /. c, pp. 97, 98, pi. 3, fig. 10 (1891); Brunner, 



I. c, pp. 83, 85 (1895)- 



A single female from Batanga. It was collected in April by F. H. 

 Hope. C. M. Ace. No. 5293.
