NEW BRITISH SPECIES, N05IENCLATURE, ETC. 137 



known males and females of Loxotropa (only an artificial 

 section of Basalys), convinces me that the query should be 

 erased. 



Some time ago I collected materials for a monograph of 

 the British Belytides, but circumstances have hitherto pre- 

 vented its completion. Nees described 13 species under 

 Behjta and 2 under C'metus. But, as he seldom mentions 

 the characters upon which Forster's genera are founded, it 

 is not easy to refer the species to their proper jilaces. B. 

 petiolaris, Nees, = Cineius ; B.hisulca, Nees, = Oxylabis ; 

 B. bicolor and rufopetiolata^ Nees, = Xenotoma ; B. 

 brcvis, obscura, and abdominalis, Nees, = Zygota (?) ; 

 B. anomala, Nees, = Ismarus. B. sanguinolenta^ Nees, 

 = Belyta, Forst., and is the only one of the Neesian species 

 which can now be referred to that genus. C. picipes and 

 Jurinei, Nees, = Occylabis, and according to Haliday are 

 the same as C. armatus, Curt. 



Thomson's paper (Ofv. 1858, pp. 155 — 180), the only 

 other authority for the Belytides, makes no reference to 

 Forster's system, published two years before, and of the 

 31 spp. described, only 6 belong to Belyta {scnsu str.). All 

 of these I have identified in this country, Belyta^ Forst., 

 excludes all species that have not the longitudinal carina of 

 the metathorax bifurcate near the apex, enclosing a trian- 

 gular space. Belyta, Thoms., on the other hand, includes 

 Psilomma, Forst., = Opazon, Hal., and Zygota, AcUsta, 

 iir]d Pa?itoclis, Forst. Under Cinetus undAcoretiis, TJioms., 

 are arranged the rest of Forster's genera, except Synacra, 

 which, following Mr. Haliday's advice in litt., I have referred 

 in the Catalogue to the Diapriides. Lytcba, Thorns., == 

 Oxylabis, Forst. Xenotoma, Forst., is richer in species 

 than the other British genera, and most of them are un- 

 described.
