OETHOPTERA OF INDIANA. 285 



times yellow; the middle third with a broad curved black band which 

 reaches nearly to the anal angle; the front margin with a dusky bar 

 reaching nearly to the base; the apical third pellucid. Outer face of 

 hind femora reddish brown, with three dark, oblique bars on the 

 upper half; inner face with alternating bands of black and yellow. 

 Hind tibiae whitish, with a dark ring at each end, and a broad one 

 of the same color just above the middle; the apical halves of spines 

 black.

In Indiana the ''long-horned locust" has been noted only in Lake, 

 Porter and Laporte counties in the sandy area bordering Lake Mich- 

 igan, where it was first taken July 27, 1897. It is most common along 

 the beach Avithin one-half mile of the lake, in company with Tri- 

 merotropis maritima (Harris) and Spharagemon wyomingianum 

 (Thorn.), though a few specimens were taken on sandy ridges five 

 miles from the lake shore. It has a quick, short flight, and always 

 chooses a bare, sandy spot on which to alight. Unless it is carefully 

 "marked down" it is then very difficult to distinguish, sinc'e its colors 

 harmonize so perfectly with its surroundings. By keeping an eye on 

 it, and stealthily approaching it can readily be taken by throwing 

 the net quickly over it just as it is in the act of rising. The male 

 makes a slight rattling sound as it flies, but the movement of the 

 female is noiseless. The majority of the specimens taken had the 

 inner wings a bright red at base, though variations in color, from 

 light yellow to deep red, were frequent. It may possibly be found 

 to occur on the sand covered areas throughout the northern third 

 of Indiana, though it is probable that it is limited to the area imme- 

 diately adjoining Lake Michigan. 



Sub-family ACRIDINiE. 



The Indiana species of this sub-family may be easily recognized by 

 the presence of a distinct spine or tubercle on the prosternum be- 

 tween the front pair of legs. They vary much in size and general 

 appearance, and among them are found our most injurious insects 

 of the order Orthoptera. 



The head is, in general, smaller and less swollen than in the two 

 preceding sub-families. The face (except in Leptysma) is rarely very 

 oblique, often nearly perpendicular. The disk of vertex is never
