364 A CATALOGUE OF THE HEMIPTERA OF FIJI, 



Length 3J-4£mill. 



Yiti Levu (March; Muir's No. 102), on a native tree; Rewa 

 (March; Muir). 



This is nearest, perhaps, to P. marmorata Champion, from 

 which it differs by the different form of the pronotum, the 

 minutely multisinuate lateral margins of the tegmina and the 

 different cell-form of the costal area, also by the genital segments. 

 It differs from any species of Phatnoma by the middle keel of the 

 pronotum extending beyond the apical margin, and by the very 

 long labium. 



Holophygdon, gen.nov. 



Very distinct from any other genus by the form of the pro- 

 notum. Allied remotely to Gargaphia Stal. Head small, almost 

 angularly convex above, spineless. First segment of antennae 

 longer than head. Buccube high, extending slightly beyond 

 head, the space between them oval. Labium not reaching to 

 base of mesosternum, and there are no sternal sulci, or at least 

 only broad, somewhat impressed areas between the ambulacra. 

 Pronotum entirely composed of a large subglobular cyst, largely 

 reticulate, medianly keeled, not covering the head; the sides are 

 thus not at all carinate, explanate or foliaceous, and the basal 

 margin is perpendicular, not acutely produced. Discoidal area 

 scarcely visible, tumid. Subcostal area largely reticulated 

 irregularly, and there is no costal area differentiated. Tegmina 

 extending far beyond abdomen. 



54. H. melanesica, sp.nov. (Plate iv., figs. 10-11). 



Pale yellowish, legs, etc., paler. Apical four-fifths of last 

 segment of antennas, tarsi, apex of labium, etc., black, Tegmina 

 hyaline (except discoidal area), veins pale yellow, sometimes 

 apically fuscous. Length 3 J-3J mill. 



Viti Levu (November; Muir's No.34), on a native tree-climbing 

 plant; Rewa (April and December; Muir). 



Nesocypselas, gen.nov. 

 Allied to Derephysia Spinola, but very different from anything 

 known to me. Head minute, spineless; antennas slender, second
