are seen resting on the bare sand and occasionally making a 

 short quick fligiit. Bciiibcx spiiwUf is occasional. The Beinbe- 

 ciihr oviposit in burrows in the sand and provision them with 

 flies. The red female Mnf////(/(r are conspicuous as they walk 

 hurriedly along, presumably in search of insects with which 

 to stock their nests, often followed by the black, winged 

 males. (PI. XIV., Fig. 1; XV., XVI. ) Predaceous flies, Anfhrax 

 and Asi/ !</(/', the latter including La j)lii/sfi(i, are common, rest- 

 ing on the sand or Hying al)Out. (PI. XIV.. Fig. 2; XVI.) Those 

 alert personiHcations of incessant activity, the Ceropa/iihf, flit 

 rapidly along near the ground amongst the vegetation, (PI. 

 XVI.,) searching for spiders for their nests, and if the spider 

 Pliidippus insoh'iis did not look so much like a female mutillid 

 it might not be able to assume the manner which gives it 

 its specittc name. Of course the grasshoppers are a conspicu- 

 ous feature of the blow-sand, Mfhni()j)liis JidrijJus and M. (tii(/ns- 

 fipi'/uiis and the In'ight-winged (EilipodiiKc — such as Spharaiji'- 

 liioii /ri/oiniiii/i<(iiniii, HIjipisnis, Pshiidia feiiestralis, and others — 

 jumping about or flying here and there over the bare sand. ( PI- 

 XIV., Fig. 1; XV., etc.) 



Logs, boards, dried dung, and other shelters are not very 

 common on the sand prairie, but underneath them we hud a 

 second and very interesting group of insect associations. At 

 the Devil's Neck we have found Gnjllns pcrsuHutns, Xotfiopus 

 zabroides. CciifhnpJiilns sp., Gcopimis iiici-ass((f/is, Cnifacitiitliits 

 (Ji(hii(S, HarpaJiis cd/ij/iHosiis, Aiusaddrtj/his rusflnis, Tcnnes flav- 

 ipi's. and others, the ('(irahidn' all (juite al)undaut. In June 

 many Xofl/opiiy were found here, but all were dead. Under 

 bark and sticks on sand under trees (PI. XX., Fig. 2) were 

 fsc/niopfei-d inieqiKiIis. UdfopAijIhi rohii.sfa, and some curious 

 cyduid nymphs. Beneath boards on very sandy pasture land 

 were Lacon fectan(/itJi(s and Opafr/ii/is iiofiis in abundance, also 

 Harpdhi.'itestaceiis and H. errafinis. the latter commonest. Un- 

 der the remnants of a dead animal in a l)lowout were Tro.r sra- 

 bnjstm and Cunthoii iii(jrirontif<. 



A third group are the burrowers in bare sand, among which 

 are the tiger-beetles and their larvae and various Humenoptem.
