occurred with Orphulella olivacea in the speargrass of the marshes. 

 Paroxya atlantica occurs in the marshes also, but was more common 

 locally in the pine woods, in moist grassy spots among the "ink- 

 berry" or myrtle bushes {Ilex glabra) . (PL 2, fig. 2.) 



The piney woods present two general types of habitat, wet and 

 dry, but owing to the low relief of the face of the country a very mixed 

 condition occurs, xerophile and h} r grophile species seemingly all jum- 

 bled together. In low spots, swampy places and along streams, may 

 be found Leptysma marginicollis , Tryxalis brevicornis, and Clinocephalus 

 elegans. On the drier, sandy, more open spots will be met Arphia, 

 Hippiscus, Neotettix, Orphulella, and Psinidia. Mermiria bivittata is 

 found only among coarse grasses, in either wet or dry situations. (PL 



2, fig- i). 



As has been stated in the outline of the trip, collecting in Louisi- 

 ana was perforce abbreviated by the imminence of interference with 

 travel owing to the outbreak of yellow fever. 



In the vicinity of New Orleans a brief time was spent in the field 

 between showers at Milneburg, on the edge of the swamp. Here 

 Dictyophorus reticulatus was found in numbers, and a single very large 

 example of Paroxya hoosieri, not previously known from south of 

 Indiana. A trip 60 miles down-river and back to Buras, in the marsh 

 region, occupied one day. The two species most in evidence at this 

 point were Chortophaga viridifasciata, numerous on the higher ground 

 near the levee, and Orphulella olivacea, widely and generally spread 

 in the marshes in company w r ith Orchelimum herbaceum. At Franklin, 

 owing to the flooded condition of the country, it was impossible to 

 collect to advantage except along the railway embankment, and but 

 half a dozen species were secured. At this point the eastern and 

 southern part of the trip closed. 



Arkansas was visited in its western part only, between the dates 

 July 26 to August 3 and August 28 to September 5. The earlier period 

 was spent in the southwestern part of the State at Ashdown, in the 

 lowlands; DeQueen, in rolling country ; Mena, Eagleton, and Rich 

 Mountain Station at the foot of Rich Mountain ; and on the summit 

 of Rich Mountain, at an elevation of 2,600 feet. At this earlier period 

 many species were still immature in the mountain region. During 

 the latter period collections were gathered at Blue Mountain Station 

 and the summit of Magazine Mountain, Ola, Dardanelle, and Van 

 Buren, in the Arkansas River Valley; Winslow, high up on the Ozark 

 uplift ; and Fayetteville, in the hill country of the extreme northwest.
