men black and very finely and closely punctured; the second 
segment has two oval silvery spots, one on either side, on its 
dorsal surface ; the third is covered with silvery pubescence 
above, and the fifth has a fringe on its posterior margin of 
stiff hairs of a somewhat yellower tint. Below, the segments 
are fringed with silvery hairs.

Female.—Black, with black pubescence ; a crown-shaped 
mark on the front and vertex of the head above the antenne ; 
the scutellum and postscutellum yellow ; the head, the meso- 
thorax, and the abdomen sparsely punctured, the last black, 
shining, and immaculate; the pro- and metathorax more 
closely and coarsely punctured, the latter with sparse black 
pubescence ; the sides of the pronotum produced laterally 
into well-marked rather acute tubercles or cones. 
Male.—Resembles the female, but is more slender in form, 
with longer antenne and thicker pubescence. It wants the 
yellow on the head, and the lateral angles of the pronotum 
are not produced. 
The above brief description sufficiently characterizes this 
well-marked species. It is closest to S. procer, Illig., from 
which it differs in the shape of the prothorax and the sculp- 
turing of the thorax generally. It is also quite distinct from 
Scolia frontalis, Saussure (coronata, Smith). Ihave ventured 
to name it after Mr. Whitehead, its discoverer.
