STT.FAMILY VI. OKrANTIIIXJE. 725 



Beutenmiiller ( loc. cit.) says of it: "Resembles 0. fasdatits 

 but readily distinguished by the grass green venation. The insect 

 lives only on pine trees and usually on the higher branches. Its 

 song is a continuous soft and metallic reeeeee with numerous un- 

 dulations. When many individuals are heard together their 

 stridulatiou sounds not unlike the distant jingling of sleigh-bells." 

 Fulton and Davis found it in numbers on the pitch pine, Pimis 

 rigida Mill, near Central Park, Long Island, and Davis on the Jer- 

 sey or scrub pine, P. rirginiaiia Mill, at Bloonisburg, Pa. Fulton 

 (1915, 41) states that the female deposits the eggs about 3 mm. 

 apart in regular rows in pine bark. 

 340. OECANTHUS LATIPENNIS Riley, 1881, 61. Broad-winged Tree Cricket. 



Size large for the genus. Greenish-white, male, pale yellowish-green, 

 female; occiput and eight or ten basal joints of antennas pinkish, the former 

 sometimes with four faint dusky streaks; pronotum often with a median 

 dusky stripe, darkest in front; tegmina and wings of female often dusky 

 at tips; legs white, knees yellowish; hind femora with a small dark spot 

 near tip. Tegmina of male wider than in any other species. Wings much 

 shorter than tegmina, male, surpassing their tips, female. Length of body, 

 $ and 9. 1317; of pronotum, 3 3.3; of tegmina, $, 13 1C, 9, 1314.5; 

 of wings, c5 , 12, 9, 15 17; of hind femora, $ and 9, 10; of ovipositor, 

 G.5 mm. Width of tegmina, $ , 6.5 8 mm. 



This, our largest species of OecantJnis, occurs throughout 

 southern Indiana but has not as yet been taken in the northern 

 half of the State. It is found mostly on shrubs and vines along 

 fence rows, roadsides, and especially in thickets along the borders 

 of streams and with us appears to be most abundant in October, 

 though adults have been taken the last of August. 



The known range of 0. latipennis is southern extending from 

 Long Island and Xew Jersey west to Missouri and Nebraska and 

 south and southwest to Georgia and Alabama. Fulton mentions 

 it from Michigan and Lugger, without definite locality, in his 

 Minnesota work. Riley records a male from Columbia, Texas, 

 but afterward states that it had black marks on antenna?, which 

 would preclude its being latipennis. 



The eggs of the broad-winged tree cricket are usually laid in 

 the pith of the smaller twigs of shrubs and vines, preferably in 

 tiie slender twigs of the wild and cultivated grapes. Riley (loc. 

 cit.) has described the method of oviposition as follows: 



"The jaws are first used to slightly tear the outer bark. With the 

 antennae stretched straight forward and the abdomen bent up so as to 

 bring the ovipositor at right angles with the cane, the female then com- 

 mences drilling, working the abdomen convulsively up and down about 

 twice each second. The eggs are laid lengthwise in the pith, but always in
