THAMNOBATES.— NANNOTETTIX. 437 



in media longitudine exarato; margine postico leviter arcuato. Lobi laterales margine infero crasso, 

 calloso. Elytra abdomen parum superantia, lanceolata, apice anguste rotundata, tota coriacea, dense 

 punctato-reticulata ; vena ulnari anteriore prope apicem marginis postici excurrens. Alae leviter 

 infumatae. Presternum bispinosum. Pedes breves ; femora anteriora et intermedia subtus spinis 3-4 ; 

 postica basi inflata, parte apicali breviter gracili, subtus spinosa. Lobi geniculares omnes mutici. Tibiae 

 anticse tetragonae, supra planae, foraminibus hiantibus, posticae supra spinis apicalibus nullis vel una 

 instructae ; tibiae intermediae compressae, supra muticae. 



5 5 . Ovipositor gracilis, arcuatus. Lamina infra-genitalis trigonalis. 



<5 <$ . Lamina supra-analis trigonalis. Cerci breves, truncati (apice spina transversa armati). Lamina infra- 

 genitalis postice attenuata, stylis instructa. Campus tympanalis elytri sinistri pone venam stridulantem 

 nigro-opacus, ille elytri dextri vitreus. Vena axillaris 2 a venae stridulante parallela et illi contigua. 



This genus comes close to Cocconotus. It differs from it in having the tympana of 

 the anterior tibiae more opened, the femora without spines on the apical lobes, the 

 elytra comparatively short and lanceolate in form, the ovipositor arcuated, and the 

 pronotum rugose, with much thickened lateral edges. 



1. Thamnobates subfalcata, sp. n. (Tab. XX. figg. 30-32.) 



Statura minore, colore fulvo-testacea ; capite et pronoto supra rufo-testaceis. Frons laevigata, utrinque infra 

 subcarinata, in medio lineis 2, utrinque linea interrupta vel maculis 2, necnon macula rotundata ad 

 clypeum, fuscis (vel immaculata). Pronotum dense rugoso-granulatum, marginibus lateralibus incrassatis, 

 late callosis. Elytra grisea, acuminata, punctato-reticulata, venis parum prominulis, apice hebetato. 

 Pedes breves, spinis concoloribus, femora antica et intermedia subtus spinis 3 ; postica vix tertia parte 

 apicali lineari, subtus spinis 6-7. Tibiae anticae supra latiusculae, planae. Lamina supra-analis parva, 

 trigonalis, impressa. 



2 . Ovipositor gracilis, sensim arcuatus, femori postico sequilongus, ad apicem tuberculis 2 (primo lineari, 

 perpendieulari), notatus ; margine supero ad apicem vix perspicue crenulato ; margine supero et infero 

 dimidia parte apicali fusca, parte intermedia testacea, subtilissime punctulata. Lamina infra-genitalis 

 acuta. 



d . Elytra paulo breviora, apice paulo minus acuta. Cerci teretes, breves, apice extus in dentem excurrentes, 

 intus processum spiniformem perpendicularem praebentes. Lamina infra-genitalis apice angustata, late 

 canaliculata, truncata, minute incisa, cercos haud superans, stylis instructa. (Styli deleti.) Vena 

 stridulans elytri sinistri cylindrica, intus baud acuminata.

<$ . Long. corp. 205 ; pronot. 5'5 ; elytr. 17 ; femor. post. 12 millim.
