31. Hemisphcerius dubius, n. sp. PI. IV. fig. 17. 

 Hemisphesrim Schaumi, Walker, MS. (nee StSl). 



Entire structure the same as in II. bipustulatus, of which it 

 may be a variety ; the fronts is of the same fusiform shape, 

 scarlet, with the margins and central ridge green ; the head 

 narrow, testaceous above ; scutellum and basal margin of 

 tegmina greenish testaceous; tegmina fulvous, with basal half 

 of costal margin and apical margin edged with black ; a broad 

 sigmoidal black central band, and below it, connecting it with 

 the inner margin, a mass of congregated black atoms ,• two 

 or three brownish atoms towards the apex ; venter creamy, 

 with the anus and a broad transverse band black ; legs reddish 

 testaceous, longitudinally streaked with green and black at the 

 knees. 



Length 4| millimetres. 



Hab. Ceylon, Ramboddo (Nietner). Type, B.M. 



I do not know how far the species of Hemisphcerius are 

 subject to variation ; so far as I have seen they seem to be 

 pretty constant ; still, from the perfect identity in structure of 

 this species with H. bipustidatus, I feel some doubt of its 

 distinctness. The H Schaumi of Stal is described as " dirty 

 yellowish, with greenish yellow frons, a central red streak ; 

 hemelytra dirty subhyaline, the anterior part of costal 

 margin black, and a small sutural black spot, two some- 

 what curved oblique submedian yellow lines : length 5, width 

 5 millimetres. Island of Taprobana." This may be another 

 variety.
