This species has been taken in Indiana only near Pine, Lake 

 County, where eight specimens were secured on June 20. They 

 were found on open, sparsely vegetated sandy tracts, about a 

 fourth of a mile back from the shore of Lake Michigan. One of 

 the females has the inner wings pinkish or coral-red, as in tiibcr- 

 cnl<ifiif<; two have them orange-red, the other yellow. Of the four 

 males, two have yellow and two orange-colored wings. This is the 

 most eastern record for the species, and it probably occurs in In- 

 diana only in the sand-covered area of the northwestern portion. 

 The known range of H. li<ii(J<'in<uiii extends from northwestern 

 Indiana to Colorado, south to southern Illinois and middle Kan- 

 sas. It is not recorded in any of the Canadian lists, though it 

 probably occurs in southern Manitoba. From Illinois Hart (1907, 

 232) has recorded it as common in the sand region, associated with 

 H. pJicenicopterus. He adds: u The intercalary vein in Hi/i/iiKcux, 

 especially in this species and phcenicopterus, is quite prominent 

 and bears a row of minute tubercles, as in .l/rro.v/r////rv ; and the 

 upper carina of the internal face of the hind femur is rubbed 

 against it, causing a distinct rasping 1 stridulation. The sound 

 may be easily produced in this way in freshly killed individuals. 

 In all the Illinois Oedipodinie the same structure of the inter- 

 calary vein occurs, and presumably also the same habit of stridu- 

 lation by means of it when not flying." 



Brunei- (1897, 131) says that lidldciiHtnii is "one of the most 

 common large mottled locusts in eastern and middle Nebraska," 

 but in Minnesota Somes found it very scarce and says: "It is 

 more solitary in habit than most members of the genus, but one 

 specimen being found in each of three localities, these among the 

 low scattered grasses of very dry soils." It is not listed by Gil- 

 lette (1904) from Colorado, though recorded from there by Scud- 

 der (1892, 280). The Himnxrits minus Saussure (1884, 86), de- 

 scribed from Colorado, is regarded as a synonym and the Illinois 

 records of Oc^Ji/xxJa nct/ln-fa Thos. and the Himrixrns tubcrcuJatus 

 of McNeill (1891, 63) are to be referred to 



116. Hippiscrs RTcosrs (Scudder), 1862, 469. Wrinkled Locust. 



Form rather bulky, short-bodied. General color light to dark brown; 

 face and abdomen brownish-yellow; disk of pronotum with a pale, x-shaped 

 mark, often absent in female. Antennae yellow at base, apical half red- 

 dish-fuscous. Tegmina ash-gray, often darker in male, the sides and dor- 

 sal area with numerous dark brown or fuscous oblong or rounded spots, 

 those on middle of sides larger; apical third often semi-transparent, with
