medio sparse cinereo-pilosis. 
Head and thorax punctured-rugose, more finely and closely on 
the head than on the thorax, abdomen punctured, the second dorsal 
segment longitudinally rugose-striate, pygidial area not defined. 
Head rounded behind the eyes, very little broader than the thorax ; 
the eyes broadly oval, situated a little nearer to the posterior 
margin of the head than to the base of the mandibles. Antenne 
stout, the scape very finely punctured, the second joint of the 
flagellum nearly half as long again as the third. Thorax almost 
twice as long as broad, the anterior margin straight, the sides 
parallel, obliquely sloped posteriorly, the surface of the posterior 
slope rugose, the scutellar tubercle absent, a faint longitudinal 
carina on the median segment ; pleura shining and almost smooth, 
not concave, the dorsal surface of the thorax convex. Abdomen 
short and broad, strongly convex, the second segment less than half 
as long again as the breadth at the apex. Tibi with only two or 
three very feeble spines near the apex.

Mutilla thermophila, sp. nov. 
g. Ferruginea, tennessime punctata, abdomine nigro, subsessile. 
Head, thorax, and abdomen finely and closely punctured, the 
punctures on the second dorsal segment of the abdomen often con- 
fluent longitudinally. Head not quite as broad as the thorax, 
rounded behind the eyes, which are a little nearer to the posterior 
margin of the head than to the base of the mandibles, oval and not 
very prominent. Antenne moderately stout and rather short, the 
second joint of the flagellum short, equal in length to the third. 
Thorax convex, nearly half as broad again posteriorly as anteriorly, 
about one-third longer than the breadth on the posterior margin, 
the sides not emarginate or crenulate; the anterior margin 
straight, very slightly prominent at the angles. Pleura finely 
punctured, very slightly concave, the propleura almost smooth. 
Abdomen subsessile, strongly convex, the first segment depressed, 
the second very broad, nearly as broad in the middle as long, 
sixth segment without a pygidial area. Second ventral segment 
coarsely punctured, deeply depressed transversely at the base. 
Tibiz almost smooth, with only one or two very slender spines near
