NEMOIJIUS FASCIATUS (DeGeer), 1773, 522. Striped Ground Cricket. 

 Size large for the genus. General color dark reddish-brown to dusky 

 black; head and pronotum usually darker than the other parts; occiput 

 with four more or less distinct blackish stripes; tegmina in great part, 

 lower part of lateral lobes and cheeks pale brownish-yellow; nymphs usu- 

 ally with a median dorsal dark stripe on abdomen and a broad dark band 

 on lateral lobes. Pronotum about one-third wider than long, its bristly 

 hairs very numerous. Tegmina dimorphic in length, nearly as long as 

 hind femora and reaching nearly to tip of abdomen in both sexes (fascia- 

 tus) , often one-half shorter and reaching only the middle of abdomen in 

 female (vittatus). Wings also dimorphic, surpassing tip of ovipositor in 

 macropterous female, represented by mere scales in brachypterous one. 

 Ovipositor, rigid, straight, apical fourth very feebly sublanceolate at tip, 

 with upper valves serrulate above. Length of body, $ , 7.2 10.6, $ , 8

The long-winged or typical form of this ground cricket is 



I have 



taken it in the field on but two or three occa- 

 sions, and then in small numbers on the stems 

 of tall grasses about the margins of marshes. 

 However, many have been taken from the walks 

 and streets of Indianapolis, Fort Wayne and 

 other cities and towns in the northern part of 

 the State, but none, as yet, in the southern half, 

 not even in Terre Haute, where I resided for 

 seven years. Where the long-winged form 

 breeds, and feeds by day is to me unknown. Tt 

 a pj tears to reach maturity about July 15th as, 

 at times, in the first week in August, swarms 

 composed of myriads have appeared about the 

 lights of some of the cities. The newspapers 

 the next day had a column or more devoted to 

 the insects but nothing, except wild guesses, as 

 to whence thev came. 



much less common in Indiana than the short-winged one.
