The Tribulus Group. 



We have recently decided that obovatipennis Blatchley is 

 nothing more than a race of rusticus (Stal) . Examination of topo- 

 types of tribulus Morse and a paratype of devius Morse in the 

 author's collection now show that the latter is a synonym of the 

 former, but that the species which has usually been recorded in 

 the literature as tribulus is actually a distinct undescribed species 

 here named delaware. In addition, a paratype of tribuloides 

 Morse in the author's collection is found to have a very different 

 penis from that of tribulus or delaware and is not a race of trubulus 

 as was indicated by Blatchley in 1920. 



The species belonging to the present group we arrange in the 

 following sequence: tepidus Morse, morsei Blatchley, rusticus 

 obovatipennis Blatchley, rusticus rusticus (Stal), delaware here 

 described, tribuloides Morse, tribulus Morse and decoratus Morse. 



Melanoplus delaware new species (PI. XXII, fig. 16; pi. XXIII, 



figs. 1 and 8) 



This species has been recorded as tribulus from Clove Valley, 

 Reeds Valley, Graniteville, Lambert's Lane, Watchogue and 

 Richmond, New York (Davis); Ramapo Mountains, Ramsey, 

 Barnegat, Reega, Belleplain, Sea Isle Junction, Dennisville, Dias 

 Creek (Fox) and Stafford's Forge (Rehn and Hebard), New 

 Jersey; Pink Hill, Pennsylvania (Rehn and Hebard); Beltsville 

 and Plummer's Island, Maryland (Rehn and Hebard); Pohick 

 (Rehn and Hebard) and Wingina (Davis) Virginia; Weldon,
