 $ . Long. 36 ; pronot. 9-5, femor. ant. 9-25, elytr. 7'5 millim.

Hab. Mexico, Morelia (Saussure). 



Obs.. We are in possession of the larva ( 6 ) of a second species of Yersinia, from 

 Costa Rica, with shorter legs and tarsi, but it is too young for description. 



LITANEUTRIA*, Sauss. 

 Litaneutria, Saussure, Societas Entomologica, 1892, p. 123. 



Caput triangulare; scutellum faciale mediocre, planum, superne angulato-rotundatum. Ocelli elliptici, 

 mediocres, in trigono regulari exserti : inferum transversum, superi obliqui, convergentes, ad exteriorem 

 spectantes. Oculi ovato-fusiformes, divergentes, superne subprominuli, angulati, acuti (tuberculati). 

 Yertex inter illos humilior, compressus, subacutus, ab antico subsinuatus. Pronotum minutum, brevius- 

 culum, distincte carinatum, ante basin subconstrictum. — Elytra et alse( <5 )explicata, angusta, membranacea, 

 abdomine breviora. Elytrorum campus marginalis a medio ad apicem angustius. Alarum campus ante- 

 rior angustissimus, vena ulnari furcata ; (disco fusco-maculato) ; margine postico et apicali sublobulato. — 

 Pedes antici breves, graciles ; femora subgraciles, extus spinis 5 (ultima subapicalis), subtus spinis 

 discoidalibus 3 brevibus. Tibiae spinis extus 7-8. Pedes postici gracillimi ; metatarsus posticus elongatus, 

 reliquis articulis sequilongus. Abdomen ( <J ) elongatum, bacillare. Lamina supra-analis rotundata, cari- 

 nata. Cerci mediocres, laminam infragenitalem vix superantes; haec elongata, apice carinata, stylis 

 minutis instructa. — Feminse ignotae. 



This genus belongs to the group of Gonypeta, on account of its general form and its 

 very long hind metatarsus. Litaneutria much resembles Ameles, but differs from it in its 

 long tarsi and coloured wings. The carinated pronotum seems to approximate it to 

 Tropidomantis, Stal ; but in that genus the vertex is more elevated than the eyes, the 

 cerci are very long, the ulnar vein of the wings is biramose, &c. 



Litaneutria appears to be the only American type known of the group oi'Gonypeta. 

 The females have probably abbreviated wings.

$ . Prasina, gracillima. Scutellum faciale fere duplo latius quam altum ; oculi superne leviter prominuli, haud 

 acuti, vertex inter sulcos humilior, transversus. Frons impressionibus 2 notata. Pronotum ampliatione 

 ovata ; parte basali modice angusta, quam ampliatio fere dimidio breviore. Elytra quintum abdominis 

 segmentum tegentia, subhyalina, venis et campo marginali virescentibus vel griseis. Campus marginalis 

 angustissimus basi ampliatus, venulis transversis rectis. Vena analis libera. Area analis venis obliquis 3. 

 Alae in areolis griseo-maculatse, campo postico prope basin macula majore fusca, violascente. Campus 

 anterior posteriorem baud multum superans, margine apicali oblique truncato, apice rotundato, sinu anali 

 obtusissimo ; vena ulnari valde ultra medium furcata. Pedes haud maculati ; coxae anticas inermes ; 

 femora extus granulata. Lamina supra-analis fere duplo latior quam longa. 



Long. 27'25 ; pronot. 5*2, femor. ant. 4*8, elytr. 18, latit. elytr. 3-5 millim.
