Color : vertex tawny yellow, a line between the fulvous ocelli broken for- 
ward in the middle, a transverse band between the anterior portion of the 
eyes and a spot in each basal angle usually connected by a bracket-shaped 
mark hung from the middle of the band in front, fuscous. Pronotum irreg- 
ularly fuscous marked, usually a fairly definite band of spots on the anterior 
submargin. Elytral nervures pale testaceous, margined with fuscous, the 
cross nervures broader and lighter. Face with the sutures, arcs on front and 
a spot on apex of clypeus fuscous. Below dark ; legs dark or sometimes 
annulate with pale. 
Genitalia : female segment half longer than the penultimate, posterior 
margin weakly produced in the middle and at the lateral angles ; male valve 
semicircular, plates triangular, two and one-half times as long as the valve, 
the margins with coarse hairs. 
Habitat : mountains of Colorado and Mt. Washington, N. H. 
This and the three preceding species form a little group of closely 
related forms in which the genitalia are of little value. In fact, 
this and the five preceding species are much alike in genital char- 
acters and it is only on the shape of the head, elytra and color 
pattern that they are readily separated. The shorter and more 
compact form, longer head and deep chestnut color will readily 
distinguish this species. 
ATHYSANUS DENTATUS OSB. AND BALL. (Plate 17, fig. 5.) 
Athysanus cienlahis Osb aiul Ball. Proc. Dav. Acad. Nat. Sci. VII. p. 95, 1898. 
Smaller and lighter colored than arctostaphyli , which it somewhat resem- 
bles. Pale testaceous, faint lines or spots on front margin of vertex and a 
wavy line on the disc forming an X-shaped figure. Length, 3mm ; width, 
1 mm or less. 
Vertex narrow, but little wider than long, roundingly angled before, nearly 
flat, the apex but very slightly conically produced. Face narrow, but almost 
parallel-margined. Elytra about as long as the body, inclined to be flaring, 
venation often indistinct, as in arctostaphyli, the central anteapical cell not 
as strongly constricted. 
Color : vertex pale j'ellow, six indistinct spots on the anterior margin some- 
times united into an irregular broken line ; the posterior disc with a median 
pale X-shaped figure and a pale spot on either side at the base, the whole 
margined with a continuous brown line. Pronotum brownish or olive, the 
anterior margin yellowish, set off by a row of fuscous spots of which the 
median pair are the most distinct. Scutellum dirty yellow with a pair of 
brown spots on disc in line with those on pronotum and vertex. Elytra pale 
testaceous subhyaline, the nervures slightly lighter, sometimes a cross nervure 
on clavus and the one between the sectors are distinctly lighter and set off by 
a fuscous spot. Front testaceous with short, light arcs and a light spot below, 
rest of face pale yellow with sutures and spots on the apices of lorae and 
clypeus brownish fuscous. 
Genitalia : female segment abruptly narrowed one-tliird the distance from 
the base, exposing a pair of light colored membranes, the lateral angles of
