almost equals in size, it is readily distinguished by the shorter ovipositor 

 of the female, and by the greater length of the inner wings which, in both 

 sexes, extend about 7 mm. beyond the tip of the abdomen. 



Mature specimens have been taken as early as June 1, so that it, also, 

 must winter in the larval state. Tt seems to be more fond of the society of 

 man than any other species, and is the one which was usually heard chirp- 

 ing about the hearths of the large, old-fashioned fire-places. It is often 

 found about houses and barns in towns and cities, and a number of speci- 

 mens have been secured by the writer from beneath electric lights. 



All the measurements of both this and (/. abbrevlatus, exceed those given 

 by Mr. Scudder, in his paper in the Boston .Journal, loc. cit., yet, otherwise, 

 Indiana specimens fully agree with the descriptions. 



Measurements: Male and female — Length of body, 21 mm.; of posterior 

 femora, 13 mm.; of ovipositor of female, 14 mm.

Several females of a short, broad-bodied cricket have been taken in Vigo 



county, which are evidently distinct from either of the above members of 



this genus, and are referred with some doubt to this species. The wing 



covers reach to the end of the abdomen while the posterior femora and 



ovipositor are much shorter than those of the two preceding species. The 



body in the longest specimen measured but 1") mm., and the wings of all 



were very much abbreviated or absent. They were taken in September 



from beneath logs. 



Average measurements : Length of bodj^ 14 mm.; of wing covers, 10 

 mm.; of posterior femora, 8 mm.; of ovipositor 7 mm. 



IV. Xemohius, Serville (1839). The Striped Ground Ci'ickets. 

 Of all the ( iryllidee which occur in the Northern states, the little brown 

 ground crickets are the most numerous and the most social. I'nlike their 

 larger cousins, the field crickets, they do not wait for darkness before seek- 

 ing their food, but wherever the grass has been cropped short, whether 

 on shaded hillside, or in the full glare of the noonday sun along the beaten 

 roadway, mature specimens may be seen by hundreds during the days of 

 early autumn. They are all of small size, being never more than half an 

 inch in length. The color is a dark brown, and the bodies and legs are
