THE CICINDELA LECONTEI OR PINE ASSOCIATION (Stations 57, 58, 59; Tables L, LI, LVI, LVIII) (Figs. 201) (115, 170) a) Subterranean-ground stratum.—^Here we find the larva of the bronze tiger-beetle {Cicindela scutellaris lecontei) (170), with its straight, cylindrical burrow. Several digger-wasps of the earlier stage are recorded as continuing. The ant {Lasius niger americanus) nests beneath the sand and was seen swarming in early September. The burrowing spider continues and an occasional cicada lives deep beneath the sand. The six-lined lizard {Cnemidophorus 6-lineatus), the blue racer, and the pond turtle (Chryseniys marginata) all bury their eggs beneath the sand. There is an occasional thirteen-lined ground squirrel. Fig. 194.—The lesser migratory locust {Melanoplus allanis) (after Lugger). {Citellus ij-lineatus) (162), though it is never common. The surface of the ground is frequented by the adults of the tiger-beetles, digger- wasps, the six-lined lizard, and the blue racer (157). The grasshopper of the transition belt continues and two others are added, so that we have the long-horned locust, the narrow-winged locust, the lesser locust, the mottled sand-locust {Sparagemon wyomingianum Thom.), and sand- locust (Ageneotettix arenosus) (40). The ruffed grouse nests here occa- sionally. b) Field stratum.—Arabis lyrala is a common herb. ShuU (175) found that the larva of a cabbage butterfly feeds upon this. He watched a larva crawl on one of the bunches of bunch-grass for six hours before it began to spin the bed of silk preparatory to pupating. This was about 2 in. above the ground. Midges and mosquitoes are common and dragon- and damsel-flies are nearly always in evidence resting on the grasses and herbs and picking up the midges and mos- quitoes while on the wing.
