 where on the previous visit it was only occasionally found.

In the present series there are but seven specimens in the green 

 color phase, all of which are females and, with the exception of one 

 individual from Miami, were taken at Key West. One of the female 

 specimens from Key Vaca and one from Key West show a decided 

 approach to this color form, but in these specimens the face and 

 dorsal surface of head and pronotum are suffused with ferruginous, 

 while the bases and tips of the caudal femora are washed with madder- 

 red, which color is more faintly indicated on the contiguous portions 

 of the tegmina. In a large number of the darker specimens before 

 us, the light cruciform marking on the pronotum is very noticeable. 



This decidedly campestrian species was abundant wherever found. 

 The insects fly up with alacrity when disturbed, making a whirring, 

 clicking sound in their flight. Although this species is always found 

 in large colonies, the insects are sufficiently wary and rapid in flight 

 to cause the capture of a series to be quite a task. 



Scirtetica marmorata picta (Sc). 



Capron, Fla., April 24; 1 9 [U. S. N. M.].

After examining about one hundred specimens of Scirtetica mar- 

 morata from Massachusetts, Connecticut and New Jersey and 

 eighty-one specimens which are referable to picta, we have reached 

 the conclusion that Morse's suggestion 20 that the two forms are but 

 geographic races of the same species is strongly supported by our 

 material. Unfortunately, we lack specimens from eastern Virginia 

 and northeastern North Carolina, but we now have a sufficient
