The abdomen is joined to the thorax by a distinct jointed pedicle ; it is of an oval form, broadest behind and pointed in front, and without any lateral transverse constriction. It is of a dull yellowish hue tinged with reddish ; on either side towards the hinder extremity is a large black spot ; along the middle of the upperside on the hinder half are two converging rows of small white spots, with some other white ones towards the fore extremity ; on each side also of the fore half are two broadish, but not very strongly defined, oblique brownish stripes, the hinder ones meeting at an angle in the middle and continued in the median line to the fore end. The genital aperture is well marked and of a very characteristic form. Hab. Singapore. Sent to Mr. Shelford by Mr. H . N . Ridley, Director of the Botanic Gardens, Singapore.
