armed with spines, the remainder like the 9 ; the abdomen ob- 
long, and marked like the 9, but with an additional band, and 
sometimes more interrupted, the second and fifth and sixth bands 
generally the widest, frequently entire, the terminal segment 
having a central longitudinal groove.

+4} As this insect, which I have named in honour of a 
distinguished Hymenopterologist, does not agree with any 
excepting Panzer’s figure and description of his Cr. cepha- 
lotes, yet as the latter apparently mixes two species, his 
name becomes a doubtful synonyme. This doubt is 
increased by St. Fargeau making it the synonyme of his 
Crabo striatus, with which mine cannot agree, as from its 
structure it decidedly belongs to his genus Solenius ; whereas 
its d as evidently belongs to his genus Ceratocolus, and is 
very like his Cer. striatus ; but certainly different, for he 
does not notive the remarkable peculiarity in the stria- 
tion of the dorsolum, which is transverse anteriorly, and 
longitudinal posteriorly. These two insects further con- 
firm my views in not adopting his genera; for here again 
two are linked together by the sexes of the same species. 
This species appears rare. I have not hitherto taken it 
myself. Mr. Walker has captured it in the vicinity of 
London, in July; and Mr. Stephens at Ripley in Surrey.
