OETHOPTEEA OF INDIANA. 435 



on anterior half. Tegmina reddish brown, lighter along the humeral 

 angle, covering a little more than half the abdomen in the female, 

 three-fourths or more of abdomen in the male. Wings present but 

 very narrow and shorter than the tegmina; abdomen shining black. 

 All the legs reddish brown throughout, except the hind femora which 

 sometimes have the apical half of outer and inner faces blackish. 

 These femora are short and rather slender. Hind tibise with six or 

 seven rather long spines on their outer carina. Ovipositor nearly 

 one and a half times longer than hind femora, the average ratio 

 being 1.43:1, dark reddish brown in color. 



Measurements: Length of body, male and female, 15 mm.; of pro- 

 notum, male, 3.2 mm., female, 3.5 mm.; of tegmina, male, 9 mm., 

 female, 7 mm.; of hind femora, male, 10 mm., female, 11.5 mm.; of 

 ovipositor, 16.5 mm. Width of pronotum, male, 4.7 mm., female, 

 5 mm. 



This species has been taken only in the sand dune region of Lake 

 County, Indiana, where it is rather plentiful in September and Octo- 

 ber beneath logs and chunks in bare sandy places. It is more slender 

 bodied than any of our species except the house cricket, G. domesti- 

 cus, which it resembles in form. The reddish brown color of teg- 

 mina, legs and cerci, contrasts strongly with the deep black of pro- 

 notum and abdomen. It will probably be found in sandy localities 

 in the northern half of the State, especially in those counties bor- 

 dering Lake Michigan.
