OETHOPTERA OF INDIANA. 443 



inner face. Abdomen black, with a lighter brown lengthwise band 

 on each side of its dorsal surface. Ovipositor equaling the hind 

 femora in length, yellowish brown in color, the apex darker. 



Measurements: Length of body, male, 11.5 mm., female, 14 mm.; 

 of pronotum, male and female, 3 mm.; of tegmina, male, 4.5 mm., 

 female, 3.5 mm.; of hind femora, male and female, 9.5 mm.; of hind 

 tibite, male and female, 6 mm.; of ovipositor, 9.5 mm. 



This species, resembling in general -appearance a large Nemobius. 

 has been taken only in Knox, Gibson and Crawford counties, where 

 it occurs on dry wooded hillsides beneath flat stones and logs. It 

 seems to like best places devoid of grass and other vegetation. In 

 southern Indiana it probably reaches maturity about the middle of 

 June, as it seems to be most abundant by the last of that month. 

 Quite a number of specimens were taken in the vicinity of Wyan- 

 dotte Cave in 1902. It is a southern species which has heretofore 

 been recorded only from Georgia and Florida, and it will therefore 

 probably be found only in the southern third of Indiana. 



Sub-family CECANTHIN^^l 



This sub-family comprises the slender bodied ivory or greenish 

 white tree crickets. Our Indiana species have the pronotum elon- 

 gated and narrow, its sides deflexed, the posterior margin somewhat 

 broader than the anterior. The wing covers of the male are flat- 

 tened, semi-transparent, rather firm in texture and much broader 

 than the body. Those of the female are wrapped close about the 

 body, causing such a difference of appearance between the two sexes 

 that collectors often take them for widely different species. The 

 hind femora are weak and slender. The tibiae, in our most common 

 species, are armed with delicate spines between which are minute 

 teeth, visible only under a lens. The tarsi are four-jointed, elon- 

 gated and compressed, the second joint being very small and com- 

 pressed. The ovipositor is straight and shorter than the hind 

 femora; its apex a little enlarged and rather blunt. 



All our species are strictly arboreal, living mainly on vines, shrub- 

 bery and the taller herbaceous plants. They especially frequent the 

 various species of golden-rod and wild sunflowers, and often three or 

 four can be found on a single one of these plants. For the most part 

 they remain quiescent during the day, but are quite active at night. 



Scudder recognizes but one genus, (Ecanthus, as belonging to our 

 fauna. One species, however, has no spines on the hind tibia% and 

 since the presence or absence of these spines is deemed of sufficient 

 importance to be used as one of the principal characters in separat-
