INSECTA SAUNDERSIANA. 
base; interstices flat, finely punctulate, showing, when the insect is fresh, 
rows of distant very small denudate dots; coloured and clothed like the 
head and thorax. 
Pygidium oblong-semielliptic, longer than the thorax, oblique-sub¬ 
horizontal, punctate, pitchy, covered with a short dense yellowish pile. 
Body beneath more or less rufescent, here and there spotted with 
blackish. Pectus rather distantly, abdomen finely and densely, punctate; 
covered with a thin silky whitish gray or whitish yellow pile; sides of the 
rings having a white punctiform spot. 
Legs: —Four anterior slender, first pair the shortest; pale rufous or 
testaceous: intermediate thighs flat and concave underneath. Posterior 
legs nearly as long as the whole body: thighs thick, clavate, having inside 
near the apex a rather long acute spine or tooth, to which are added two 
very minute crenulations. Tibice bent at the base, then straight, rather 
dilated towards the tip, which is subtruncate and has four spines, one inside, 
one in the middle, and two outside close to each other; these two latter 
very minute. 
Obs. —This species varies in the coloration of the ground and pile: 
there are specimens of a very light rufous colour; others much darker, 
marked with pitchy patches. Some of them are clothed with a yellowish 
fulvous pile, others with grayish or ashy, and there are specimens which 
perfectly link these extreme varieties. Sometimes the tomentosity of the 
elytra is interrupted in lines, so as to form obsolete tessellations, but never 
so well indicated and regular as in Br. obtectus , Say.
