ALYDINA. 
ALYDUS, Fab. 
A very peculiar genus, which may be at once known by 
its somewhat elongate form, prominent eyes, and long 
curved apical joint to the antenne, which in our British 
species is almost as long as the second and third together ; 
the clavus is very short, and the apical margin of the 
corium is very long ; the connexivum is not dilated, and 
the posterior femora are very long, and armed beneath with 
several spines ; male genital armature visible from above, 
the genital segment being open posteriorly. There are 
only two European species of this genus, of which we have 
one in this country. 
A. calearatus, Linn.—Brownish-black, clothed with 
short erect black hairs. Head with the eyes situated at 
some distance from the pronotum ; no distinct antenniferous 
tubercles; antennae with the second and third joints 
testaceous, except at their extreme apices; ocelli very 
prominent ; pronotum slightly widened behind, with its 
front and side margins nearly straight ; posterior angles 
rounded, base slightly produced, with an emargination 
opposite the scutellum ; dise punctured and finely rugose ; 
scutellum punctured, produced to a sharp point at the apex ;
