C. americanus, Sauss., from Cuba, differs from this species in its very rudimentary 

 elytra, covered by the hind part of the pronotum.] 



LIPHOPLUS, Sauss. 

 Liphoplus, Saussure, Mel. Orthopt. 5 e fasc. p. 483 (1877) *. 



This genus is now recorded as American ; it was only known previously from Oceania 

 and Burmah. The anterior tibiae have a very small drum on their inner face, somewhat 

 turned back on the upperside. In the females the drum is only apparent as a small 

 point ; in the males it is somewhat larger, orbicular, and very distinct, but sometimes 

 obliterated on one of the tibiae. 



l. Liphoplus mexicanus, sp. n. (Tab. XL fig. 37.) 



c? . Rufo-testaceus, depressus. Antennae concolores. Caput et pronotum canescente squamosa. Scutellum faciale 

 valde tumidum, sulco divisum. Pronotum grande, depressum, antice valde angustatum, postice valde dila- 

 tatum, margine postico transverse arcuato. Elytra ilium longe superantia, segmenta ultima abdominis 2 

 liberantia, quam pronotum latiora, testacea, plana ; campo laterali deflexo, angusto, ad inferum reflexo, per 

 venam longitudinalem crassam luteam diviso, dimidia parte marginali (basi et apice except a) nigrescente. 

 Campus dorsalis latissimus, apice late rotundatus, marginibus rufescentibus ; speculo maximo, subtrigonali, 

 margine postico arcuato, angulo antico sub margine pronoti recondito, disco toto irregulariter flabellatim 

 pliculato, ac per venam rectangulam diviso. Pedes run, albido-squamosi ; femora crassa. Tibiae posticae 

 leviter arcuatae, superne planae, canthis acutis, denticulis minutis numerosissimis confertim armatoe. 

 Calcaria interna : intermedium tertiam partem metatarsi aequans ; superum breve, quam inferum brevius ; 

 hoc longitudine dimidium intermedium aequans, vel plus. Calcaria externa minima : superum paulo 

 longius quam inferum, ab intermedio remotum. Metatarsi postici compressi, superne biseriatim denticulati. 

 Tarsi omnes apice nigri. Abdomen in parte apicali attenuatum, nigrum. Lamina supra-analis minuta, 

 transversa, deflexa, sulco divisa. Lamina infra-genitalis elongata, pilosa, apice denticulos 2 formans. 

 Cerci longi, run. 



cJ . Long. corp. 9 ; pronot. 37, latit. 3 ; elytr. ultra pronot. 2-9, latit. 3-8 ; femor. post. 5 millim. 



Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 



* Ebratttm. — In my Synopsis of the Myrmecophiliens, p. 456, the genus Liphoplus is placed under the 

 number 5, 5 : the number 5 has been omitted for the genus Arachnocephalus (" tibiae posticae graciles " etc.) 

 after 4, 4.
