146 ORIENTAL CICADID.E. 



This species is allied to P. fatinnn, Stiil, but differs by its much greater size and distinct coloration, 

 and also by the different arrangement of the venation to the tegmina, most notably in the size and shape 

 of the apical areas. 



Hab. — Malayan Archipelago: North-east Celebes (coll. Dist.). 



3. Prasia hariola. (Tab. VII., figs. 16, a, h.) 



I'lasin Hariola Still, Trans. Eut. Soc. Lend. ser. 3, vol. i. p. 574 (1863). 



" Griseo-straminea ; tegminibus alisque sordide hyalinis, illorum margins costali ultra medium albido; 

 thorace utrimque distincte sinuato. 2 ." 



" Long. 21, exp. tegm. 60 millim." 



" Prtecedenti* similis, minor, forma thoracis mox distinguenda. Vertex oculo transverse pauUo latior. 

 Ocelli postici inter se quam ad oculos paullo magis approximate Thorax margine antico subelevato, 

 lateribus obtusissimis, fere ab apice ad medium parallelis, dein postice subito ampliatis. Tegmina areolis 

 apicalibus prima, tertia, quarta, quinta et sexta longissimis. Femora antica subtus apicem versus 

 bispinosa (spina tertia subbasali lcesa?)."t

4. Prasia fatiloqua. (Tab. VI., figs. 2, a, h.) 



Prasia fatiloqua, Stal, 6fv.Vet.-Ak. Forh. 1870, p. 718, n. 1. 



This species is only known to me by a typical male specimen kindly lent for illustration 

 by Dr. Aurivillius, of the Stockholm Museum, and I append Stal's original description. 



" Pallide ohvaceo-virescens, tegminibus sub-concoloribus, pellucidis ; scutello postice medio sub- 

 ampliato, metanoto medio pone apicem scutelli prominulo et medio rugoso-elevato." 



" ^ . Long. 19, exp. tegm. 60 mill." 



" (? . Abdomine inflato, operculis nullis ; segmento dorsah ultimo angulis apicalibus in processum 

 subcurvum productis ; segmento ventrali peuultimo transverso, posterius rotundato et medio subtruncato ; 

 segmento ultimo obovato mediocri." 



" P. hariolee simillima, ocellis minoribus, vertice latiore, oculis fere duplo latiore, fronte basi latiore, 

 scutello basi medio nonnihil producto et subdepresso, areis apicalibus plurimis tegminum brevioribus, 

 area ulnari interiore (quinta) apicem versus sensim nonnihil ampliata anastomosibusque curvatis differt." 



Hab. — Malayan Archipelago: Philippine Isles (Semper — Stockh. Mus.). 



5. Prasia foliata. (Tab. XV., figs. 1'2, a, b.) 



Cephaloxys foUata, "Walker, List Horn. Suppl. p. 37 (1858). 

 Prasia foliata, Stal, Ofv. Vet.-Ak. Forli. 18G-2, p. 483. 



"Male. Testaceous. Head with the front porrect, triangular, acute. Prothorax much broader than 

 the head ; border narrow behind, broader on each side. Abdomen broader than the thorax. Fore wings 

 testaceous, somewhat opaque, slightly convex in front ; first transverse vein slightly undulating, very 

 oblique, but not in the usual direction ; second very oblique, much curved, twice the length of the first, 

 from which it is parted by full its own length ; third oblique, curved ; fourth nearly straight, very slightly 

 oblique. Hind wings vitreous." 



" Length of the body 8 lines ; of the wings 20 lines." 



Hab.— Malayan Archipelago : Celebes (Mad. Pfeiffer— Brit. Mus.) ; Sangir (Doherty— coll. Dist.). 



The figure is taken from Walker's type in the British Museum. 



■•■ P. faticina. 



f I did not detect a third subbasal anterior femoral spitie in tlie female specimen from New Guinea which passed through 

 mv hands.
