posterior portion of metathorax somewhat roughened. Alaa 
smooth, almost impunctate excepting apically and ventrally, where 
rather strong punctures are to be found, but the disks of these segments 
are practically impunctate; last ventral segment with a longitudinal 
keel or carina; dorsal surface of pygidium with large coarse punctures, 
the intervening spaces with minute ones. 
Coloration: Ground color of insect black, the following areas deep 
yellow: Mandibles except tips, clypeus, face below and _ between 
antenne, inner orbits rather widely up to level of anterior ocellus, 
scape and pedicellum beneath (flagellum missing), collar above pos- 
terior portion of tubercles, part of tegule, a median spot on scutellum 
and postscutellum, a large ovate spot on each side of the third abdom- 
inal segment, a small lateral spot on four, a rather wide band on five 
narrowed laterally. The legs are colored as follows: Anterior coxe, 
trochanters, femora and tibie in front, and tarsi, yellow; intermediate 
coxze and trochanters with a yellow dot, femora and tibie in front, 
yellow, tarsi rather darker; hind legs entirely brownish. Wings

Type—A female taken at*Beaver, Indiana on August 17, 
1894. I take pleasure in dedicating this species to Prof. Robt. 
H. Wolcott, M.D., collector and donor of the specimen, who 
has added many valuable insects to the University collection. 
The second abdominal segment has two or three tiny yellow 
spots showing through. Other specimens of the species are 
quite likely to have these spots more strongly developed, or en- 
tirely absent. 
In order that students may have no difficulty in placing this 
species, the following modification of the latter portion of Fox’s 
synopsis (Entomological News, V, p. 201, 1894) is submitted. 
4. Clypeus, except fore margin in male, metathorax, petiole and second 
abdominal segment, without yellow markings; third abdomi- 
nal segment with a yellow mark on each side ; in the male the 
scape and first two joints of the flagellum beneath, yellow.
