 camund (T. V. CampheU). South India; Chikkaballapura and 

 Salem {T. V. Campbell). 



Most neai'ly allied to P. homhayensis, Dist. 



Prof. Maxwell-Lefroy, in forwarding specimens of this species, 

 informed me that "we have reared this from nymphs which are 

 fixed to mango leaf, very tightly pressed down on to it so as to be 

 very difficult to see ; they are more or less transparent, and sit 

 motionless, very much as a scale insect does. They are not 

 commoc." 



3456. Petalocephala bainbriggei, sp. n. 



Pale virescent ; body beneath and legs more ochraceous, apices 

 of tibiae and tarsi more or less opaline-green ; vertex of head 

 shorter than breadth between eyes, finely punctate, centrally ob- 

 scurely longitudinally cariuate, the lateral margins almost straight 

 in front of eyes and then broadly oblicjuely rounded to apex : 

 pronotum moderately convex, finely punctate and transversely 

 wrinkled, the posterior laternl angles rounded, the base concave; 

 scutellum closely rather coarsely punctate, the apical area trans- 

 versely striate ; tegmina subliyaline, the claval and subclaval areas 

 more opaque and virescent, the claval area thickly coarsely punc- 

 tate, and somewhat at right angles with the rest of the tegmina. 



Length inch tegm. 9 milliu). 



Hah. South India ; Coimbatore {T. Bainbriyge Fletcher), 



Allied to the preceding species, P. granulosa, from which 

 it differs by its larger size, more oblique lateral margins of 

 the vertex, the non-granulated clavus, different colour and 

 markings, &c.

 ochraceous ; vertex of head nearly twice as broad at base as 

 central length, broadly obliquely convex, centrally longitu- 

 dinally ridged, the anterior area darkly tuberculous ; face pale 

 ochraceous, more or less blackened anteriorly ; pronotum with the
