carinate. Front with crowded, good-sized punctures, its pubescence short, 
erect, grayish white. Antennae black, joint 3 exceeding 4 or 5, the pro- 
portion being 5:3:4, following joints about as broad as long. Cheeks 
shiny, closely and distinctly punctured, clothed with long, white hair. 
Malar space striate, about three-fifths as long as broad. Prothoracic spine 
moderate but distinct and sharp. Mesothorax with coarse, crowded, or 
even semi-cancellate punctures, well separated on a small shining disk, the 
mesopleura punctured like the disk. Entire scutellum coarsely punctured, 
postscutellum finely and densely punctured. Superior face of metathorax 
well-defined, the pits large and shiny, square medially only. Enclosure 
funnel-shaped, the bowl coarsely transversely rugose, the rugae more or 
less completely interrupted in a median line, the neck smooth, concave, and 
polished, twice as long as wide. Sides of metathorax and areas surround- 
ing enclosure opaque, minutely punctured. Pubescence of thorax above 
grayish white mixed with black, these forming a decided scutellar fringe. 
A fringe from insertion of wings to and including postscutellum, sides of 
metathorax and mesopleura with long, pale hairs. Tegulae black. Wings 
hyaline, nervures and stigma dark brown. Legs black with grayish white 
pubescence, the inner tarsal apices with golden brown tufts, the basal joint 
of hind tarsi four and one-half times as long as broad. Anterior coxae 
simple. Claws ferruginous, medially toothed. Spurs of hind tibiae pale 
testaceous, the outer ones very finely pectinate. Abdomen shining, sub- 
oval, segment 1 polished, with a small, close, distinct puncturation, closest 
laterally and becoming sparser toward a median subimpunctate line, seg- 
ment 2 uniformly more finely punctured, following segments indistinctly 
punctured, apex roughened. Base of abdomen with only a few white hairs 
and those mostly along the sides, apical margins of segments 1-4 with dis- 
tinct, narrow, white fasciae, the first one interrupted medially, segment 5 
merely fringed. Disks of segments with short, scattered pale hairs, on 
segments 4-6 with longer black bristles interspersed.

and wing structure, the dorsal hairs paler, the punctuation of the abdom- 
inal segments coarser.” [Malar space about as long as broad—T. D. A.

Type Locariry.—Beulah, New Mexico; types in collection of 
Philadelphia Academy of Natural Sciences. 
The types of this species were collected at Beulah, a female in 
rgor by Dr. Skinner, for whom the species was named, and a pair 
on August 18 by Professor Cockerell. [I have examined three 
females collected at the same time as the pair, thus being of the 
same lot, but have as yet seen no males, so can not illustrate the 
armature and seventh ventral plate of this species. I wish to
