Class. — Orthopteka. 



Natural Order. — Locustites, ined. 



Genus. — Ripipteryx. Newman. 



Caput cordatum, (PI. VII., fig. 3.); oculis magnis ovatis (ce); ocellis 

 tribus, (ce) lateralibus oculos, medio clypeum, fere attingentibus ; 

 clypeo siibquadrato, elongate (se) ; antennis 10-articulatis, prnpe 

 OS insertis (y). Os (fig. 2) partibus omnibus distinctis ; labrum 

 conspicuum, quadratum, (a) angulis rotundatis; labium divisiones 

 quatuorperspicue dispandens ; insertione (u. l)elevato, labii mag- 

 nitudine ; labio proprio {u. 2) lateribus, ante medium, productis, 

 apice paullo angustiori, medio obsolete emarginato ; palpigero 

 (u. 3) minori, angustiori, labipalpos quasi tri-articulatos ferenti ; 

 ligula (m. 4.) in quatuor lobis palpiformibus quarum intermediis mi- 

 nutissimis, lateralibus manifestis, divisa; m.axillse validse, lacinia 

 (o. 4) elongata, acuta ; galea (o) palpiformi, quasi biarticulata, 

 articulo (anne articulus ?) basali minimo, apicali elongato ; maxi- 

 palpis (6) articulis quatuor, quorum apicali robustiori, omnino 

 majori ; mandibul^e validse, (2) apice vix acutsp. intus unidentatse : 

 lingua perspicua, linguiformis. Prothorax integer, supra obcor- 

 datus valde convexus. Segmenta sequentia pariter patetacta. 

 Telum (fig. 6) in laciniis quatuor divisum, appendicibus sex 

 armatum ; laciniis externis patefactis, internis minutis ; ap- 

 pendicibus quatuor, externis minutissimis, duobus internis 

 elongatis, obtusis. Proalse brevissimse, coriacese, contortse. Met- 

 alae maximae, longitudinaliter plicatse, quasi flabellum, nervuris 

 38 longitudinalibus directis, unica transversa undulata, costa 

 coriacea : metalse pulcherrimas, maxime mirandse. Propedum 

 (fig. 5.)femoribus, tibiisque simplicibus, tarsis quasi bi-articulatis, 

 articulo primo angustissimo, brevissimo, subtus in lobum producto, 

 secundo elongato, attenuate extus crassiori unguibus duobus 

 armato. Mesopedes propedum characteres habent. Metapedum 

 (fig. 4.) femoribus dilatatis, marginibus attenuatis, intus concavis, 

 extus convexis, alas quiescentis aliquatenus recipientibus ; tibiis 

 rectis attenuatis, apice limbo producto acuto ; tarsorum loco, 

 duobus appendicibus rectis, acutis, suppleto. 



At a future time I hope to offer some opinions as to the 

 affinities of this extraordinary genus ; at present I must leave 

 the proficient in entomology to draw his own conclusions 

 from the description and accompanying figures.
