ENTOMOLOGICAL SECTION.

Laporte, Colorado, May 17th, and one taken by the writer at Fort 
Collins, Sept. 27th. Both obtained by sweeping native plants. 
It is not improbable that this species and the preceding may 
have to be taken out of the genus Deltocephalus. A study of long- 
winged forms, which probably exist, would help to settle the matter. 
The short elytra and greatly exserted ovipositors are strikingly sim- 
ilar to those parts in Deltocephalus argenteolus Uhl., and Atliysanus 
curtipennis G. & B., but the conical shape of the vertex and the 
strongly produced clypeus is in contrast with those species and also 
with the species of the genus Domtura, J. Sahib. 
ATHYSANUS ORNATUS, n. sp. 
A shining black species with posterior portion of the pronotum 
and the elytra, except three transverse black lines, white. Length 
3 m. m. Vertex very broadly rounded, the length a little less than 
the distance between the eyes and almost exactly equaling the length 
of the pronotum ; color polished black. Face of the same color as 
the vertex, except that there are two spots on the base of the clypeus, 
one near the angle of each cheek, and about eight interrupted cross 
lines on the front that are of a yellowish brown color. Front short and 
broad, rapidly narrowing to the clypeus.; clypeus rounding at the 
base, parallel sided, truncate at the tip. Entire width of the face once 
and one-fifth the length. Pronotum shining black on anterior third, 
pale yellow on posterior two-thirds, and two and one-half times as 
wide as long. Scutellum black with the apex white. Elytra short, 
just covering the last segment of the tergum, the corium but little 
exceeding the clavus ; in color glaucus white, with the extreme base, 
the tip, and a transverse band on the middle of each, shining black. 
Tergum deep shining black ; venter mostly yellow, the bases of the 
segments more or less black, the last segment entirely black and a 
little concave on the hind margin ; pygofers and ovipositor glossy 
black and short. Legs blue black with considerable yellowish 
brown coloration. 
Described from a single female, example taken by the writer at 
Fort Collins, May 28th, sweeping native plants. 
This is a very handsome species, and is readily recognized by the 
black head and white wing covers with the three tran verse black 
lines.
