admitting that it is perhaps more closely related to the Tryphoninae 

 than to the Pimplinae, still retams it in the Pimplinae, and, under the 

 name Oedematopsis, assigns it and Thymaris to the tribe Acoenitides 

 and adds a new species. Schmiedeknecht ^ retained it in the Pimp- 

 linae, where he tabulated it between Lampronota and Arenetra, 

 although he took note of Thomson's placing of it. Later ^ he tabu- 

 lated it with Neliopisthus and Thymaris in the Tryphoninae; and 

 still later ^ he follows Thomson, using the name HyopJianes, and call- 

 ing the tribe and subtribe Mesoleptini and Thymaridina, respectively. 

 Viereck * places Ilyhoplianes nasutus (Cresson) in his genus Pledis- 

 cidea under the name Plectiscidea (Campothreptus) nasuta Cresson. 



Thymaris has been the basis of but little less disagreement than has 

 Hyhophanes. Originally placed by Foerster^ in his family Campo- 

 plegides, where the only characters assigned to it are those employed 

 in the key, no species was assigned to it until Brischke ® described his 

 Thymaris pulchricornis. Brischke also considered the genus Campo- 

 plegine. Thomson^ described two species and removed the genus, under 

 the name Thymarus, to his subtribe Thymarides. Bridgemau and 

 Fitch ^ and later Bridgemau^ described Thymaris fasciatus , which, as 

 pointed out by Schmiedeknecht ^ almost certainly does not belong 

 to the genus as typified by pulchricornis Brischke, but is apparently 

 a true Campoplegine. Ashmead^" followed Foerster in his placing of 

 Thymaris. Pfankuch " synonymized Thymans pulchricornis Brischke 

 with Mesoleptus tener Gravenhorst, Schmiedeknecht,^ without refer- 

 ring it to any tribe, tabulated it in a generic synopsis of the Try- 

 phoninae; and later ^ adopted Thomson's disposition of the genus. 

 He synonymized compressus Thomson with pulchricornis Brischke and 

 expressed doubt of the synonymy of Brischke's species with Meso- 

 leptus tener Gravenhorst, though admitting that a part of the male 

 material of Gravenhorst's species belongs here. Morley ^" placed Thy- 

 maris with Oedemopsis in the Acoenitini and described a new species. 

 Neliopisthus Thomson, aside from its original description by 

 Thomson/ has been treated at length only by Schmietleknccht,* 

 who follows Thomson in his disposition of the genus. Ashmead,^* 

 failing to recognize it, redescribed it as Polysphinctomorpha and 

 placed it in the Pimplini. In the same work (p. 179) he simply 

 listed Neliopisthus in liis bibliography of the genera.
