leviter punctulata) puncturis sat magnis subquadratis in- 
structis, his (et seriebus et in seriebus puncturis) sat crebre

Extremely like the preceding, but a slightly stouter form, and 
distinguishable (apart from the antennal spine) by the very 
different proportions inter se of the antennal joints, and the 
different pattern on the elytra, which consists of a common mark 
resembling the letter U, extending almost from the base to the 
apex ; whereas in the preceding the pattern consists of a wide 
subapical fascia, from the front of which on each elytron (a little 
nearer to the suture than to the lateral margin) a narrow vitta 
runs forward nearly to the base of the elytra. The eyes are 
evidently more approximated above than in any of the allied 
forms in my collection, and the antenne are slightly stouter. I 
cannot but acknowledge the possibility that this may be the male 
of the preceding insect, but if so the sexual differences are 
certainly very unusual in including a considerable elongation of 
the third joint of the antenne in the female. Moreover, as I 
have two examples of S. fraternum, and the pattern on their 
elytra is absolutely identical, and markedly different from that 
of the “ var. ? vittatwm,” the differences look still less likely to be 
sexual
