considerable numbers of Diehromorphn ; iridis, Sturoderus (Stenobothrus) 

 curtipennis, Melanoplus scudderi, Melanoplus obovatipennis, Melanoplus 

 femoratus, Conocephalus fasciatus, and Conocephalus riigropleurum. Cer- 

 tain species were scarce in most places, but were found to be common or 

 even abundant in one or two restricted areas. Tbus Hippiscus rugosus 

 was found in only one place, but was there quite common. Paroxya 

 Jwosieri was taken in numbers in a swamp (16) in the Wabash bottoms 

 opposite Battle Ground but was not observed elsewhere. A peculiar variety 

 of OrcheUmum nigripis and Conocephalus attcnuatus literally swarmed in 

 a boggy depression (14) on the upland about 2 miles northwest of West 

 Lafayette. The former variety I did not find in any other place, while of 

 the latter I noted elsewhere only a single individual which I captured in a 

 bog in the Wabash bottoms (6) about half a mile south of Lafayette. 



Certain species were observed to be of rather infrequent occurrence 

 but could hardly be called rare. Among these were Schistocerca americana, 

 Melanoplus viridipes, Melanoplus gracilis, Scudderia texensis, Scudderia 

 furcata, Neoconocephalus palustris, Conocephalus nemoralis and Atlanticus 

 testaceus. The following species appeared to be quite scarce : Truxalis 

 brevicornis, Orphulella speciosa, Chlwaltis eonspersa, Schistocerca alutacea, 

 Melanoplus walshii, Neoconocephalus robustus crepitans and Conocephalus 

 saltans.

1. A fairly extensive bit of woodland on the edge of the upland about 

 a mile northwest of West Lafayette. The timber was in part rather dense, 

 but there were a number of open spots well fitted for sylvan Orthoptera. 

 There had been no grazing in the portion of the woods where the collecting 

 was chiefly done, so there was considerable undergrowth. Most of the 

 land which these woods covered was dry or only moderately humid, but it 

 included one or two depressions where the ground was eitber soggy or 

 covered with standing water. One of these, a very limited tract, was 

 included in the northwestern edge of the wood and was occupied by an 

 almost pure growth of button-ball bush (Cephalanthus occidentalis) ; the 

 other was slightly larger and occupied by a mixed growth of sapling silver 

 maples (Acer saccharimon) and red-berried elder bushes (Sambncus 

 racemosa) together with a variety of other plants. Both of these swampy 

 areas proved to be quite barren in Orthoptera. The best collecting was 

 done along a path entering the woods at its northwest corner and in the
