strongly macropterous condition. Only a strongly macropterous 

 phase has been found in graciUimus. In darker specimens the 

 abdomen is strikingly marked as in graciUimiis with three narrow 

 dark bands, one mesal and the others lateral, the two intervening 

 spaces forming iisualty bright 3'ellow bands. In such specimens 

 the lateral lobes of the pronotum are usually marked mesad with 

 a diffused dark postocular stripe. The cerci are of the same form 

 as in gracillimus and bright green in coloration during life. The 

 genicular lobes of the caudal femora are normally bispinose; the 

 genicular areas are not darkened; unlike graciUimus the ventro- 

 external margins are often armed with one to three very small 

 spines, in the series of thirty-four perfect specimens before us 20 

 being armed as follows: 



Number of spines, 

 Number of specimens. 



Of twenty-four Cuban specimens before us sixteen are macrop- 

 terous to varying degrees, while the entire series of thirteen 

 examples from Jamaica are semi-macropterous. 



Of the two species of the genus found in both Cuba and Jamaica, 

 this insect is much the less numerous, being found rarely and then 

 in small numbers in open areas of short grass. The species is now 

 known from Nassau, New Providence Island, Mangrove Cay 

 and Stranger Cay, Bahamas; Cuba; Hayti and Jamaica. 



In addition to the tj'pe, a macropterous male, we have examined the follow- 

 ing series of 43 specimens; 28 males, 10 females, 2 immature males and 6 im- 

 mature females.
