402 PHYTOPHAGA. [ Cassida. 
There is considerable confusion with regard to the nomenclature of 
this genus; the insects commonly regarded by British collectors as 
C. vibex, C. viridis, and C. equestris are respectively named in the 
European catalogue of Heyden, Reitter, and Weise as C. liriophora, 
Kirby, C. vibex, L., and C. viridis, L.; I have preferred to retain our 
commonly received names, as it does not appear quite certain which are 
really the Linnean species in every case, and C. viridis and C. equestris 
are apparently confused by some authors ; at all events it would be far 
better to substitute entirely new names than to cause inextricable con- 
fusion by a general intermixture.

Cardiophorus equiseti, Herbst., Er., nec Steph. Black, densely 
and finely punctured all over, clothed with close ashy-grey pubescence, 
without fulvous tinge; narrower and more parallel than C. asellus. 
Thorax convex, slightly longer than broad, with sides moderately 
rounded, nearly straight for anterior third, more contracted at base than 
in C. asellus, with central furrow distinct behind and two short lateral 
sulci at base. Elytra much wider than thorax at base and two anda 
half times as long, with sides nearly parallel for anterior half, slightly 
contracted behind shoulders and dilated at middle and thence gradually 
narrowed to apex, flattened along suture, with punctured strie, interstices 
convex at base ; antenne and palpi black ; legs black with knees slightly 
pitchy and tarsi reddish ; all the tarsal claws dentate ; apex of last two 
abdominal segments pitchy. LL. 7; mm. 
A single specimen was taken by Miss E. A. L. Daltry in long grass 
on the cliff between Tenby and Manorbier, South Wales, on May 29th, 
1889, and was sent by her to Mr. W. Blandford, for whom it was 
determined by Mr. Champion; I am indebted to Mr. Blandford for the 
above description. It is not certain whether we do not possess C. cinereus, 
Herbst., as British ; like C. equiseti, it has the tarsal claws dentate, a 
point that will separate both the last-mentioned species from the closely 
allied OC. asellus; it is, however, broader and less cylindrical than 
C. equiseti, and the pubescence is somewhat different ; according to 
Kiesen wetter the colour of the legs is much as in the above description 
of O, equiseti, whereas C. equiseti has the legs red; there are specimens 
in the collections of Stephens and Leech, without localities, that may, 
perhaps, turn out to be representatives of both these very nearly allied 
species.
