CELIDOPHYLLA. 451 



CELIDOPHYLLA *, gen. nov. 



Color viridis. Corpus va]de compressum. Antennae crassae. Caput compressum, angustum, anterius planum, 

 scutello faciali elevato, superne longiuscule mucronato ; verticis rostrum breve, trigonale ascendens, 

 sulcatum, haud prominulum ; scrobicula antennarum crassissima, anterius late plana, superne angustiora, 

 elevata. Pronotum antice truncatum, valde compressum, in medio constrictum, sulcis modice impressis. 

 Prozona canthis elevato-marginatis, tuberculatis. Metazona infundibuliformiter dilatata, retro-producta, 

 margine postico transverse arcuato, inciso. Lobi laterales postice rotundati, incisura humerali obtus- 

 angula. Elytra ampla, elongato-elliptica : margine antico basi arcuato, ultra medium subsinuato ; 

 margine postico recto, apice angulato. Vena discoidalis recta; vena humeralis ante medium ab ilia 

 divergens, ad medium marginem excurrens ; vena media ante medium oriens. Campus marginalis venis 

 obliquis remotis instructus ; campus discoidalis in areas magnas divisus. Prosternum spinis brevibus 

 conicis 2 armatum ; meso- et metasternum utrinque spinam divergentem praebentia. Alae amplae, albido- 

 hyalinae, haud ocellatae, venis et apice virescentibus. Femora omnia subtus fortiter spinosa ; spinis 

 ultimis lamellaribus, trigonalibus ; lobis genicularibus inermibus. Tibiae anticse valde compressae, supra 

 rotundato-carinatae, apice supra leviter dilatatae, a latere ad foramina subtus leviter dilatatae ; foraminibus 

 linearibus. Tibiae intermedise compressae, a latere basi fusiformes, supra planulae, marginibus acutis. 

 Tibiae postieae vix compressae, basi a latere leviter dilatatae, supra spinulis paucis remotis armatae. 

 Lamina supra-analis lata, convexa, rotundata. Cerci lamellares, trigonales. Lamina infra-genitalis tf 

 ovata, apice late subincisa. 



This genus is nearly allied to Mimetica, the pronotum being emarginate behind and 

 similarly formed ; the anterior femora, however, have not all their spines foliaceous, 

 and the anterior tibiae are not flattened above, but compressed.. The elytra are 

 also more elongate, with the anterior field much narrower than the posterior, not 

 dilated, but, on the contrary, narrowed beyond the middle, and with the humeral 

 vein separating before the middle in an acute angle ; their general shape more 

 resembles that of the type of Tanusia. The genus should be placed between Tanusia 

 and Mimetica. 



l. Celidophylla albimacula, sp. n. (Tab. XXII. figg. 3-5.) 



Yalida, viridis vel leviter olivacea. Caput angustum. Pronotum : prozona angusta, laevigata, granulis obso- 

 letis paucis, canthis 4-5-tuberculatis, sulco anteriore in lateribus evanido ; metazona rugulosa, margine 

 postico lato, transverse arcuato, inciso. Lobi laterales rotundati, crasse marginati. Elytra grandia, 

 maculis remotis rotundatis albidis conspersa. Alae albido-hyalinae. Femora anteriora subtus spinis acutis 

 compressis 3, intermedia 4, postica 8 ; primis gracilibus, sequentibus compressis, ultimis 2 lamellaribus 

 trigonali-dilatatis. Tibiae 1, 2 inermes, vel anticas supra extus ante apicem dente minuto unico ; posticse 

 supra spinulis utrinque 2. Abdomen carinatum, segmentis 1-5 supra dente erecto instructis.
