 ( It M 'ply reticulate, posterior angles acute and rather more produced than

 rather large ; elytra rather long, oblong, parallel sided until near apex,

 tibiae dilated, and the first two joints of the anterior and intermediate tarsi 

 dilated, those of the anterior pair more broadly so ; under-side black

In hot-beds, &c., rare; Guinley, Market Haiboro', &c. 



This species may be known by its oblong, parallel form, large broad 

 head, very long and slender antennae, and the dilated joints of the tarsi 

 in male, as well as by the sculpture.

 legs long, slender, bright yellow. L. f mm. 



One example only of this distinct species is known ; it was taken by Mr. Wollaston 

 near Tollbridge in 1871.
