male, its front halt' declivent, apex rounded, sides low but distinct, 

 median carina very faint, female, often absent, male; foveolne 

 shallow, narrowly triangular-; frontal eosta not prominent, flat 

 or nearly so, narrowed near union with vertex; antenna 1 short, 

 filiform; pronotum as in key. its front margin truncate, hind one 

 obtuse-angled, median carina low, cut by a small notch slightly in 

 front of middle, more deeply in female; lateral carina' distinct 

 on both prozona and metazona ; lateral lobes of pronotum deeper 

 than long, their front margin nearly vertical, hind one slightly 

 oblique, lower one as in Encoptoloplrus; tegmina narrow, surpass- 

 ing the abdomen, the apical third remotely reticulate, the cells 

 quadrate; wings pellucid with dusky venules; hind femora equall- 

 ing or slightly exceeding the abdomen, their upper margin sharp, 

 somewhat crested; valves of ovipositor strongly exserted. 



The only species of the genus occurs throughout the northern- 

 most United States and southern Canada from the Atlantic to 

 the Pacific. In the marking of the tegmina, form and color, it 

 looks much like a diminutive Hippiscus. 



112. CAMNULA PELLUCIDA (Scudder), 1862, 472. Clear-winged Locust. 



Small, slender, compressed, the size and tegminal markings very va- 

 riable. General color light brown, face reddish-brown; antennas yellowish 

 at base, apical half dusky; a dark triangular spot behind the eye, and an 

 oblong vertical black spot on the lateral lobe of prozona. Tegmina smoky- 

 brown, with several darker rounded spots on sides, these separated by 

 lighter yellowish blotches; dorsal surface usually with a dull yellow stripe 

 along the overlapping margins; wings transparent, with dark nervules. 

 Hind femora yellowish-brown, with two or three blackish bars on outer 

 face, the knees fuscous; hind tibiae yellowish-brown, basal fourth paler. 

 Abdomen yellowish beneath, the sides darker. Structural characters as 

 above given. Length of body, $, 17 21, 9, 21 25; of antennae, $, 1 9,

This small, dull colored Oedipod has been taken in Indiana 

 only near Bass Lake, Starke Co. Here a half dozen specimens, all 

 that could be found during a two-hours' search, were taken Aug. 

 L'l from a low marshy tract, on which the grass had been cropped 

 short. When flushed, the males flew noiselessly MO to r>0 feet, 

 then dropped down and squatted low between the grass blades. 

 The single female was more clumsy and did not take to wing. 

 All were found within an area of 100 square feet. It is probable 

 that the species occurs in isolated localities throughout the north- 

 ern third of the State. 



In New England Morse (1897, 80) says that it begins to ma- 

 ture about July 1, and may be found during the rest of the sea-
