latter of nearly equal width throughout, not prominent and hut gently sulcate at 
the ocellus; occiput short and only gently elevated. Antenna? slender, a little 
shorter than head and pronotuin combined, the basal joint smaller than usual, 
orange colored. Pronotum smooth, gradually widen ; ng behind, without well-defined 
carinas, the transverse grooves all very distinct and the border rather widely mar- 
gined throughout; hind margin broadly rounded. Tegmina small, lobate, their 
extremities reaching to the middle of second abdominal segment, and with their 
inner edges rather widely separated. Abdomen short, the sides but little com- 
pressed, the dorsal carina nearly obsolete, and the apex blunt, in the male gently 
enlarged and ending in a blunt upwardly directed point, as in Het>perotettix viridis 
Thos. Supra-anal plate of male abdomen triangular, quite broadly and deeply 
grooved on basal half and provided with a rather prominent carina on each side 
that extends from the outer basal angles to the apex of the mesial sulcus; marginal 
apophyses of preceding segment obliterated. Male cerci straight, rather wide and 
compressed at base, tapering rapidly to middle, from which point they are slender 
and finger like, directed slightly backward, inward, and upward. Valves of the 
ovipositor short, slender, their apices strongly hooked, the basal tooth of lower 
pair quite large and triangular. Posterior femora rather heavy, reaching the tip of 
abdomen in both sexes. Prosternal spine rather heavy, short, pyramidal, a little 
transverse.

Habitat : This insect was collected by me at Grand Junction, Colo., 
where it was present in very large numbers during the month of June. 
It seemed to be confined in its distribution chiefly to the grease- wood 
clusters, and was known by the popular name of grease-wood hopper. 
According to the method employed and the characters used by Carl 
Brunner von Wattenwyl in his recent work entitled " Eevision du 
Systeme des Orthopteres," this insect would naturally fall into the 
genus Hesperotettix of Scudder; but, since it has been the custom of 
American writers prior to this to place all short- winged acridians in the 
genus Pezotettix, I shall follow this custom here. It is quite evident, 
however, that this group will very shortly have to be revised for the 
entire country. This should certainly be done, because it is a very 
extensive one, there being fully 200 distinct species in North America 
alone, all more or less destructive in their food-habits. Many of them 
are also confined, like the present species, to special food plants. 
A MARITIME SPECIES OF COCCIM. 
By T. D. A. Cockerell, Las Cruces, N. Hex. 
Ripersia maritima Ckll., n. sp. 
Female about l^ mm long, plump, elongate-oval, naked, pure white, segmentation 
distinct, legs and antennae slightly brownish. 
When boiled in caustic soda the female turns bright yellow — a curious reaction. 
Antennte 6-jointed; 6 longest, a little longer than 4 and 5 ; 3 and 1 about equal; 
2, 4, and 5 subequal and shortest. Formula 6 (13) (245). Each joint emits a few 
hairs; the sixth several. The antennas are very small and short, and placed 
extremely close to one another, as in B. rumicis. 
Derm with numerous but scattered short hairs, and round gland-spots.
