Mantidae. 

 Stagmomantis Carolina Johansson. 



Strange to say the mantis has not yet been taken on Plummers 

 Island, and it appears to be scarce along the upper river, though 

 it is common enough in some directions from Washington. High 

 Island, Md., September 29, 1902, large nymph, Caudell; Black, 

 Pond, Va., September 14, 1913, W. D. Appel; Chain Bridge, Va. 

 August 17, 1912, Caudell. 



Phasmidae. 

 Diapheromera femorata Say. 



Common, sometimes abundant. Plummers Island: Nymphs 

 may be seen as early as April, become more conspicuous as the 

 summer progresses, mature and are seen mating in September; 

 latest adult collected November 15, 1912, H. S. Barber. One 

 obtained November 7, 1901 (R. P. Currie) lived in captivity 2 

 days during which period it laid 3 eggs. Great Falls, Md., Sep- 

 tember 4, 1899; Great Falls, Va., September 12, 1912, mating, 

 October 4, 1916, Caudell; Difficult Run, Va., October 3, 1915, 

 McAtee; Bellview to Difficult Run, Va., September 19, 1916,

Manomera blatchleyi Caudell. 



Plummers Island, July, 1907, W. Palmer; October 28 and No- 

 vember 15, 1912, H. S. Barber; Great Falls, Md., July 30, 1916, 

 Caudell. 



All these specimens are female-is, no males s having been seen. 

 This is also true of the many similar specimens taken on Long 

 Island, N. Y., by Wm. T. Davis and there is a possibility that 

 this may prove to be another species than blatchleyi. This has 

 formerly been recorded as Diapheromera velici. 



Acridiidae.
