though naturally larger altogether, is comparatively slightly 

 shorter ; and the spinose dorsal processes in the centre of the 

 hind margins of the meso- and metanotum are distinctly more 

 prominent ; the posterior edge of the pronotum is more dis- 

 tinctly carinate, and the surface much more irregular ; the 

 front margin of the head is comparatively much narrower, 

 making the head altogether less quadrate in form ; the re- 

 flexed frontal horn is considerably longer, being carried back- 

 wards the whole length of the head over the pronotum, 

 whereas in A. submaculata it is of only two thirds this length ; 

 the upper surface of the horn is narrower throughout, and 

 therefore more sharply sulcated down the centre ; the frons is 

 almost identical in form and sculpture ; spines on the posterior 

 tibia3 less acute. 



Tegmina above blood- red, mottled all over Avith snow-white 

 spots, most of which are confluent beyond the middle ; the 

 costal and external borders regularly spotted, the former with 

 white and the latter witli slaty-black spots : wings intense 

 black, spars ely spotted with white, but the spots much smaller 

 than in A. submaculata-^ the apical border washed with chest- 

 nut-red ; veius at base scarlet ; the abdominal and anal borders 

 whity brown, interrupted by the white spots : head and pro- 

 notum scarlet, the latter with black lateral anterior margins 

 and a black spot on each side ; mesonotum black, with a large 

 irregular central scarlet patch ; metanotum black, outlined 

 in scarlet ; abdomen cadmium-yellow, almost entirely covered 

 by the ordinaiy white waxy secretion common to the group ;

 streaked transversely with grey; a few white-centred glau- 

 cous-grey rounded spots scattered irregularly over the external 

 third ; costal border crossed by black spots and dashes ; ex- 

 ternal border with a marginal series of small black spots. 

 Wings below much as above, but the nervures beyond the 

 middle relieved in greyish white, and the white spots congre- 

 gated on the apical instead of tlie abdominal half, the borders 

 also greyish, veins at base scarlet, as above : body below 

 scarlet, margins of metasternura stramineous ; middle and 

 posterior coxa?, clouded with black. Exp. tegm. 89 millim, ;
