A SYNOPSIS OF THE GENUS STENOCRANUS, 



AND A NEW SPECIES OF MYSIDIA. 



(HOMOPTERA).

The genus Stenocranus was founded by Fieber in 1866 and 

 since that time three species have been placed in it from Europe, 

 minutus Fab., fuscovittatus Stal. and longipennis Curt., Macul- 

 ipes, described from South America by Berg in 1879 from a 

 single female, has never been recognized since. In 1914, 

 Crawford in his "Contribution towards a Monograph of the 

 Delphacidas" described angiistus from British Honduras, rostri- 

 frons from Cuba, and similis from Alabama. 



Stenocranus croecus of Van Duzee is now wrongly placed in 

 the genus Kelisia and sacchar Ivor lis of Westwood does not seem 

 to belong here. At present there are eight species described 

 from the New World and the following paper brings the 

 total up to twelve. 



As the original descriptions are widely scattered, for the 

 most part in publications not readily accessible to the ordinary 

 worker, it seems advisable at this time to review the genus, 

 describing the new species and giving comparative outline 

 drawings of heads and the male genitalia, all drawn to the 

 same scale. 



All of the species, so far as known, with the exception of 

 similis, occur on coarse grasses, rushes and sedges in swampy 

 and boggy places. Similis, however, occurs abundantly on the 

 bamboo-cane, Arundinaria tecta. 



Nearly all of the members of this genus are of a pale straw 

 to brown color with a more or less distinct dorsal whitish
