iiKwUhna from New York and New Jersey have a very narrow wing- 

 band, tapering out at the anal vein and falling far short of the anal 

 angle; the tegniina are without definite indication of the two prin- 

 cipal spots or bands; the dorsal hue is a dull pale sand-color; and 

 the tibi;v are whitish yellow. Typical fitruKi ( from Ualveston, Tex., 

 from Elizabethtown, 111., on the Ohio River, from Meredosia and 

 Havana on the Illinois, and from the Mississippi River shore from 

 Grand Tower to iSavaiina) has a broad complete band approacliing 

 the anal angle; the tegmina have a pair of evident spots or bands; 

 the general color is a speckled brownish ; and the tibi;i' are red to 

 orange. In the State Laboratory collections are a number of ex- 

 amples labeled "N. 111." which are intermediate between the two 

 forms above described — the wing band narrow, but not interrupted 

 except by the pale anal vein, a pair of inctmspicuous small spots on 

 the tegmina, the general color light, and the tibi.i' pale lemon-yel- 

 low. One of this type, with yellow tibia', is from Henry, 111., north 

 of Reoria, on the Illinois River. This and a ritruiii from Bird's 

 Point, Mo., were listed by McNeill in his "Orthoptera of Illinois'' as 

 Circotettl.i' I'en'Kciilf/tus. Collections of the lakeshore form of 

 maritiina were made by us along the beach of Lake Michigan at 

 Waukegan in August, 1906, in time to include the results herein. 

 These were closely like the somewhat intermediate form just men- 

 tioned as labeled "N. 111." — probably, therefore, lakeshore col- 

 lections also. The tibi;e were lemon-yellow, and identification as 

 innr'ithiia seemed admissible. Mr. Shobe succeeded, however, in 

 finding on the lake beach examples with well-marked orange tibiiv 

 not otherwise differing from those with lemon-yellow tibiiv. This 

 makes the line of division between the two species very indefinite. 

 Note 6, p. 234. — Mvlnnoplua iiidcncillt, n. sp. This was found 

 only in a restricted area beside the blowouts on the Moline Sand 

 Hill, associated with J/. Haridus and aiunistipiiiiun, to the latter of 

 which it is closely allied. It was at once recognized by my assistant, 

 Mr. Frank Shobe, and myself, as a new form because of its different 

 thoracic and femoral coloring. The male terminal structures are 

 about as in angtiKtijK-iuiitf, except that the furcula is very short and 

 strongly divergent, and the apex rather narrowly rounded. The 

 hind tibirt' are light blue, apically greenish. The species is about 

 the size and color of a//i/i'.st/pt'u/i/.s-, perhaps a trille smaller, but 

 with two noticeable color differences. The entire ventral margin 

 of the hind femora is strongly sanguineous, while in aiigusiqjen/iis
