THE ENTOMOLOGIST S RECORD. 



For/icula capensis, Thunberg, is a synonym of Diaperasticiis erijthro- 

 cepJialiis, Oliv. 



[Since going to Press, I have received, through the kindness of 

 Professor Y. Sjostedt, of Stockhohn, and his artist, Mr. A. Ekblom, 

 an excellent water-coloured drawing of Still's type of L. ochropu!', 

 which shows beyond all doubt that it is identical with the South 

 African species in my own collection, which I have determined as this 

 species. — M.B.] 



Tachycines asynamoru.s, Adelung, instead of Diestrammena 

 marmorata, Haan. 



By MALCOLM BURR, D.Sc, F.E.S. 



In a recent article {Ent. Rec, xxv., p. 228, 1913), I recorded the 

 occurrence of this curious Stenopelmatid, at St. Leonards, and in the 

 Entoinoloijist for May, 1914 (p. 145), Mr. Lucas also records it from 

 Ipswich, and gives a good figure. 



Its occurrence in a hothouse at Lille is noted by Chopard [Bull. 

 Soc. Ent. Ft., 1913, p. 284), but in a supplementary note [op. cit., 

 No. 1913) he corrects the determination, considering that it is the 

 closely related D. nnicolor, Bor., and then again a third time he is 

 obliged to come back to it [op. cit., 1914, p. 122), with the final opinion 

 that it is identical with a new monomorphic genus discriminated 

 from Diestrammena by Adelung (Ann. Mus. Zool. Ac. Imp. Sci. St. 

 Petersbim/, vii., 1902, p. 56 et seq.) under the name Tachycines. This 

 genus is closely related to Dieatrammena, differing in the armature of 

 the posterior tibiae. Chopard suggests that the German and British 

 specimens may also be referable to Adelung's species. 



Tachycines differs from TroylophilHs in the long mobile spines of the 

 anterior and intermediate femora, and from Diestrammena and its 

 allies in the unequal spines on the upperside of the posterior tibiae, 

 somewhat stouter body and rather rounded subgenital plate of the 

 female, this plate be}ng, according to Brunner, pointed and 

 triangular. 



Adelung's specimens were found in imported plants in a palm- 

 house in St. Petersburg, the owner of which considered that they had 

 come with some bark with orchid-roots from Colombia. 



I have given away most of my St. Leonards specimens, retaining, 

 unfortunately, only a single male. This has the characteristic arma- 

 ture of the posterior tibiae described and figured by Adelung : the 

 spines lie very flat and are compressed, and arranged in groups of 3-7; 

 in each group each succeeding spine is a little longer than the preceding 

 one, each group ending in a decidedly bigger spine ; there are a few of 

 the larger spines irregularly disposed. 



I possess some of Brunner's cotypes of Diestrammena nnicolor from 

 Burma, which do not show this arrangement. 



I am, therefore, convinced that the St. Leonards specimens, indeed 

 probably all the European captures, are to be referred not to Diestram- 

 mena marmorata, Haan, but to Tacliycines asynamorus, Adelung.
