2. Diophanes rosescens, sp. n. (Tab. XXI. figg. 19, 20.) 



Laete viridis. Statura magna. Pronotum rugulosum margine postieo leviter arcuato; metazona haud 



ascendente ; lobis lateralibus latioribus. Elytra apicem versus attenuata, apice parabolice rotundata. 



Venae humeralis et diseoidalis in dimidia parte distali divergentes ; vena media ante medium oriens. 



Alae pallide rosescentes, margine apicali arcuato, haud sensim truncato. Femora postica subtus spinis 



9-13 apice nigris armata. Tibise intermediae superne spinis 4-5. 

 5 . Lamina supra-analis longior quam latior, apice incisa, angulis acutis. Ovipositor validus, latus, rectus 



(margine supero recto). Lamina infra-genitalis late trigonalis, apice lanceolato-producta. 

 c? . Lamina supra-analis elongato-triangularis, rotundato-sulcata, valde pubescens, apice truncata vel 



subincisa. Cerci teretes, crassiusculi, apice obtusi. Lamina infra-genitalis compressa, frequenter sulcata, 



postice attenuata, incisa ; stylis longis, subtus sulcatis, apice baud attenuates, rotundatis, instructa. 



Elytrorum tympanum sinistrum speculo minore ; dextrum speculo magno, rotundato-quadrato.

Closely allied to D. perspicillatus, Stoll, but with paler wings, these being of a pale 

 transparent rose-colour, and also differing from that species in having a stout and 

 straight ovipositor (comp. fig. 18).

Magnus, viridis. Antennae rufae, articulis 1, 2 viridibus. Yerticis rostrum trigonale, leviter sulcatum. 

 Pronotum inaequale ; margine antico subtuberculato, postieo leviter producto, arcuato ; sulcis irregulariter 

 nigro-maculosis ; postieo profunde impresso paulum pone medium exarato ; antico supra in medio tenui, 

 utrinque lato ; mesozona utrinque nigro-striolata, crasse punctata ; metazona leviter ascendente, basi 

 utrinque impressionibus nigris notata. Lobi laterales margine crasso, angulo postieo valde obtusangulo. 

 Elytra sat longa, elongato-elliptica, subcoriacea, dense reticulata, areolis minutis translucidis ; margine 

 antico arcuato, postieo subrecto. Campus margin alis venis costalibus obliquis furcatis numerosis 

 instructus. Vena humeralis longe ante medium a vena discoidali divergens ; vena media ante medium 

 venae diseoidalis oriens. Yena ulnaris anterior recta, ante apicem marginis suturalis desinens ; vena 

 ulnaris postica recta, ante medium marginem exeuns. Alae amplae, infuscato-subpurpurescentes, trans- 

 lucidae, venis longitudinalis ferrugineis. Prosternum spinis validis 2 obtusis, longissimis cylindricis, 

 basi propinquis, armatum. Meso- et metasternum lobis trigonalibus erectis, crassis instructa ; foveolae 

 metasternales invicem propinquae, postice confluentes. Pedes validi. Femora omnia lobis genicularibus 

 minute spinosis ; anteriora subtus spinis 4 ; intermedia 6, supra mutica ; posteriora spinis 12, apice 

 nigris. Tibiae anteriores foraminibus linearibus ; posteriores utrinque valde spinosae. 



$ . Lamina supra-analis late rotundato-trigonalis. Ovipositor angustus, subarcuatus, quam pronotum vix 

 duplo longior, apice marginibus infuseatis, tuberculis nullis scaber. Lamina infra-genitalis crasse 

 carinata, apice trigonali-lobata. 



<j. Segmentum anale postice declivi-planatum, pubescens, margine postieo medio in processum minutum
