while dots along the scapular vein towards the base; areolets in front of 

 the scapular as in P. paralielus , each of the three posterior rows of 

 areolels regularly subdivided into three rows; areolets along the interior 

 border successively shorter outward from the transverse fold; tympanum 

 large. Hind wings pellucid, acute; apical patch green, with a ferruginous 

 line; veins greenish white. Length of the body 15 lines; expansion of 

 the fore wings 54 lines. 



The fore wings are broader than those of P. paralielus, and are longer 

 than the hind wings.

14. PSEUDOPHYLLUS BREVlUSCULUS. 



Fo3m. Viridis aut teslaceus ; caput untice a/bidum, carina lanceolata 

 sulcuta antennarum articulo \o angust lore ; prothorax subtiiiter 

 tvberculatus, margine antico subrotundato, laleribus fere rectis, mar- 

 gine postico rotundalo ; oviductus abdominis dimidio paullo longior ; 

 pedes robust*, spinosuli,femoribus posticis biserialim spirtosis ; alee 

 anticfc femoribus posticis plus triplo longiores, costa exleriore rotun- 

 dalo, margine interiore fere recto; alte posticce diaphuna-, paullo 

 breviores. 



Female. Green or testaceous, rather stout. Head narrower lhan the 

 fore border of the prothorax ; fore part whitish, shining, very oblique ; keel 

 of the vertex lanceolate, furrowed, shorter and narrower than the first joint 

 of the aritenna3 ; front lanceolate between the sockets of the antennae. Eyes 

 tawny, prominent, nearly round. Prothorax minutely tuberculate, with 

 two transverse impressed lines, of which the hiuder one is curved; fore 

 border slightly rounded; sides nearly straight; hind border rounded. Ovi- 

 duct slightly black towards the tip, a Ihtle more than half the length of the 

 abdomen. Supra-anal lamina elongated, obtuse at the tip. Cerci slender. 

 Legs stout; fore femora and fore tibiae with few and very minute spines; 

 spines of the middle femora and middle tibiae a liitle larger aud more 

 numerous; hind femora less than one-third of the length of the fore wings, 

 with two complete rows of rather large spines; hind tibiae with some minute 

 spines on two of the four keels. Fore wings lanceolate, moderately broad; 

 exterior part of the costa rounded ; interior border nearly straight; rows of 

 areolets between the scapular diminishing from four to one as they are 

 more remote from the base; scapular vein and externo-medial receding 

 from each other beyond the middle and including a row of areolels ; two 

 and exteriorly three rows of large areolets between the externo-medial and 

 the anal vein, some of these areolets incomplete ; a row of small quadrate 

 areolets along the interior border, which is minutely reticulated ; reticula- 

 tion larger at the base. Hind wings pellucid, a little shorter than the fore 

 wings; veins pale green or white. Length of the body 15 17 lines; 

 expansion of the fore wings 48 50 lines. 



The wings are shorter than those of P. siccus, to which this species 

 has great affinity.
