40 Prof. Westwood's further descriptions of 



capitis longitudine, apice acuto curvato et supra denticulo 

 truncato instructo ; margine interno mandibularum dente 

 latiori truncato pone medium armato. Maxillae et 

 labium ut videtur obsoleta. Antennae longiores in medio 

 partis posticae capitis insertae, articulo lmo magno 

 ovali compresso, 2ndo mediocri (annuli pone 2um obso- 

 leti), 5 sequentibus parvis fere aequalibus, ultimo fere 2di 

 magnitudine, ovali, ut videtur ex annulis tribus (2us 

 apicalibus minutis) formato. Thorax oblongo-quadratus, 

 prothorace magno, mesothorace transverso, versus angu- 

 los anticos utrinque ala rudimentaria instructo. Pedes 

 valde robusti, omnibus sub aequalibus, femoribus magnis 

 ovalibus compressis ; tibiis robustis, anticis apice spini- 

 geris ; posticis 4 extus rotundato-dilatatis ; apice interno 

 calcaratis ; tarsis magnis articulis tribus brevissimis, 4to 

 apicali maximo, unguibus robustis basi dilatatis. Abdo- 

 men basi metanoti latitudine, apice attenuato, genitalibus 

 utrinque retinacula denticulata armatis. 



The general form of the body in this genus closely 

 resembles that of the males of Sycoscapter, but the 

 structure of the mandibles, the position of the antennae, 

 and the form of the alary rudiments and tarsi separate 

 it from the other subapterous groups of fig-insects. 



Otitesella digitata, n. s. (PI. VII., figs. 43 — 51). 



Mas. Tota fulva ; mandibulis margine interno in 

 medio rotundato emarginatis, tarsis omnibus articulo 

 4to maximo ovali et in pedibus 4 posticis nigro, retina- 

 culis 4 denticulatis ; alis rudimentalibus e stylo tenui 

 biarticulato apice longe-setigero et vix mesonoto longiori 

 formatis. Long. corp. circ. 2 mm. 



Habitat in F. religiosa, in insula Tabrobana (DD. 

 Thwaites et J. Stainforth Green). In Mus. Hopeiano 

 Oxoniae. 



The singularly dilated large-sized terminal joint of the 

 tarsi and alary appendages distinguish this species from 

 every other known hymenopterous insect. 



Otitesella religiosa, n. s. (PL VII., figs. 52 — 57). 



Mas. Parva. Tota luteo-fulva ; subaptera, capite sub- 

 quadrato, angulis anticis et posticis rotundatis ; pronoto 

 transverso, breviori, subquadrato, angulis posticis setis 

 nonnullis longis instructis ; alis duabus rudimentariis
