214 Dr. F. K.is on neic 



a great number of very interesting Libellulina?, collected for 

 the Imperial Bureau of Entomology (formerly the Entoino- 

 logicjil Research Committee, Tropical Africa) in Nigeria, 

 Sierra Leone, and British East Africn. ]\lany records from 

 the earlier consignments, especially those from Nigeria, were 

 entered in the main text of the monograph and published. 

 Others arrived too late for that purpose, but in good time 

 for the " Additions," which, together with the indices, were 

 due to be issued in 1914, being the last instalment of the 

 monogra]jh. The lamentiible situation in Europe generally, 

 and in Belgium especially, leaves us little hope of seeing 

 that last part j)ublished in the near i'uture. In tlie beautiful 

 collection sent home from Sierra Leone by Dr. J, J. Simpson 

 there were four new sj)ecies, one of tiiem representing an 

 interesting new genus. Instead of sepaiate publication, 

 which was originally discussed, insertion of the novelties in 

 the monograph was preferred, upon the assumption that the 

 ''Additions'' would appear without any long delay. But 

 under the changed conditions of to-day, separate })ublication 

 was {igain considered, and decided upon. Mr. H. (tampion has 

 kindly read the descriptions for correctness ot language, they 

 being the author's own translation from the original German 

 text. 



All the type-specimens have been presented by the 

 Imperial Bureau of Entomology to the British Museum 

 (Natural History).

Closely allied to Allorhizucha Uingi, Karsch, but differing 

 in the following details : — {<i) greater number of cubito-anal 

 cross-veins (C/uq), 4 in front wing, 3 in hind wing; (A) at 

 the humeral suture a narrow interrupted light green line; 

 (c) the greenish-yellow stripes on the sides of the thorax 

 a little narrower, slightly concave instead of straight at 

 anterior margin ; [d) abdomen of male distinctly fusiform ; 

 (e) superior appendages a little longer; (/) slight difference 

 in genitalia of second segment, the internal branch of the 

 lianmle being more erect (nearly as figured in Lib. fig. 52 

 for A. pi'eussi, Karsch). Minute as these differences are, 

 they appear sufficient in their totality to justify specific 

 distinction, the more so as there are specimens brought by 

 Dr. Simpson, also from Sierra Leone, that agree ])erfectly 

 with A. klingi, as described in Lib. p. 81. The interesting
