Alale. — Body in a short oval, wider behind ; length 5 mm. (rostrum 
not included), width 4 mm. Dorsal shield convex, covering all the upper 
surface ; shining sulphur yellow, with spots and lines of a deep chestnut 
colour ; cervical grooves short and wide ; marginal grooves narrow, 
extending from the eyes to the posterior margin, where they form the 
anterior margin of the festoons, and are there wider than in the lateral 
portions ; cervical emargination deep, almost square, a little wider than 
long, behind this emargination a sur-basecl triangular spot ; from each 
anterior angle of the shield extend two dark coloured longitudinal 
parallel lines, the inner one covering the cervical groove; attenuated 
at its posterior end, and not reaching quite to an arched 
transverse line near the middle of the length of the shield, which passes 
laterally beyond the tips of these anterior longitudinal lines ; near the 
'end of the cervical grooves, the longitudinal lines swell lateralty, forming 
a large dark spot ; the second of the pair of lines, leaving the anterior 
angle of the shield, extends along the margin, becoming broad where it 
surrounds the eye, then constricted, and suddenly bending inwards ; then 
extends longitudinally, until just below the extremity of transverse arched 
band, when it again extends outward to the margin of the outermost
