66 R. I. POCOCK 



18. X^inota-enia. crassipes , C. Koch. 



Syn.: Scolioplanes crassipes, Meinert, Latzel, etc. 



Four specimens at Busalla. 



The question respecting the correct generic name for this 

 species is somewhat complex. 



In the Syst. Myr. p. 188 (1847) C. Koch established a genus 

 Stenotaenia, and referred to it two species. The first of these — 

 and evidently the type of the genus — was the species which he 

 had previously named G. linearis; the second was D.' Leach's 

 species G. acuminatus. Now G. linearis is generally recognised 

 as being referable to the genus Geophilus in the strict sense of 

 the word ; consequently, since linearis is the type of Stenotaenia, 

 Stenotaenia must be a synonym of Geophilus. 



Secondly, on the same page as that containing the description 

 of Stenotaenia — but following the description of G. acuminatus 

 — a second genus, named Linotaenia„ was constituted. The type 

 of this was a new species named rosulans. But rosulans turns 

 out to be specifically identical with acuminatus. Clearly then the 

 species acuminatus J with which cì^assipes is congeneric, is the 

 type of the genus Linotaenia. Nor is the validity of this con- 

 clusion impaired by the circumstance that C. Koch subsequently 

 included in Linotaenia two more species of Geophilidae — one 

 of which, G. nemore?isis^ belongs to a totally distinct genus. 



But when D/ Meinert revised the Geophilidae, instead of 

 clearing up this question of nomenclature, he proposed a new 

 generic name, Scolioplanes^ for G. acuminatus and G. crassipes. 

 And this name has been adopted by, I believe, all continental 

 authors.
