BERTONIELLA n. gen. 



A member of the Agraeciini allied to Lobaspis Redtenbacher. 

 from which it differs in having the tegmina and wings no long- 

 er than the body, in having the genicular lobes of the cephalic 

 femora and cephalic one of the median limbs non-spinose, and 

 in the decidedly abbreviate limbs in the male. From Gonata- 

 canthus Karny it can be immediately separated by the non- 

 spinose cephalic genicular lobes, from Anthracites Redtenbach- 

 er by the longer tegmina and shorter limbs, from Paralobaspis 

 Giglio-Tos by the absence of the peculiar fastigial development 

 of that genus, from Nannagroecia by the arcuate ovipositor 

 and from Alphopteryx Redtenbacher by the different tegmina. 



Fastigium spiniform, contiguous ventrad with facial fas- 

 tigium, antennae greatly exceeding length of body ; eyes sub- 

 globose. Pronotum in male produced caudad over tegminal 

 tympanum ; humeral sinus hardly indicated. Tegmina sub- 

 coriaceous, no longer than body, apex rounded. Prosternum 

 long bispinose. Supra-anal segment of male sub-angulate, fis- 

 sate ; cerci of male short, strongly incurved, apically toothed : 

 sub-genital plate of male with paired styliform appendages sur- 

 mounted by true styles. Ovipositor falcate, acute, margins en- 

 tire. Limbs short and robust ; genicular lobes of cephalic fe- 

 mora and cephalic lobe of median femora rounded, non-spinose, 

 caudal lobe of median femora spinose, genicular lobes of caudal 

 femora spinose ; ventro-lateral margin of caudal femora spined. 

 ventro-cephalic margins of cephalic and median femora each 

 with several spines. 



Type. B. agraecioides n. sp. 



We take pleasure in dedicating this most interesting genus to 

 Senor A. de Winkelried Bertoni, who collected the type and 

 who has done so much to make known to science the rich fauna 

 of Paraguay.
