SUBFAMILY TETTIGINAE 13 
in habitat from that species. We have not as yet taken this species in 
the northern part of the State but only at Worthington, Redwood 
Falls, and Fergus Falls. Dugger has recorded it from St. Anthony 
Falls. 
Tettix obscurus Hancock 
Tettix obscurus is a slender form, very similar in general appear- 
ance to T. granulatus but has the dorsum of the pronotum flattened 
and the median carina very slightly or not at all elevated. It is also 
very similar to the more southern species, 7. arenosus Burm., from 
which it may be distinguished by the more robust form and the less 
prominent eyes. In habitat it is found in dry open places, varying 
from sandy banks of streams to the open prairies of the Red River 
Valley. It has been taken at St. Anthony Park, Redwood Falls, Fer- 
gus Falls, and Warroad, and will doubtless be found throughout the 
State. 
PARATET Tix: Bol: 
Body granulate, scabrous, or rugose; vertex horizontal, narrower, 
as wide as one of the eyes, or slightly wider, very slightly nar- 
rowed anteriorly ; the front margin truncate and not produced beyond 
the eyes; frontal costa between the antennae more or less declined and 
rarely subsinuate toward the base; the eyes noticeably prominent and 
subglobose ; antennae made up of 14 joints; pronotum rather flattened 
above and with its anterior margin truncate; posteriorly attenuate, 
surpassing the tips of posterior femora, although sometimes abbre- 
viated ; median carina low; tegmina oval or elongate, the wings usually 
well developed ; hind tibiae with apical third gradually and considerably 
enlarged; pulvilli of posterior tarsi spiculate. This genus is repre- 
sented in North America by several species, all save one of which are 
found only in the South or West. 
Paratettix cucullatus Morse 
Paratettix cucullatus appears to be especially fond of muddy banks 
along streams and lakes, and in such places may sometimes be found 
in great numbers. Hancock has written of its habits as follows: “The 
muddy shores of the Skunk River, in Iowa, afford a favorable habitat 
for water-loving and semi-aquatic insects. Along this river, seven 
miles from What Cheer, the writer found that the Tettigids were 
unusually abundant June 29, 1894, the species mostly represented being 
P. cucullatus. Swarms, many of which were in sexual union, were 
frightened up from the immediate margin of the water while the
