178 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



rounded. The great majority of individuals of this race differ 

 from the average of fasciatus fasciatus in having the tegmina just 

 reaching the tips of the caudal femora or falling short of these as 

 much as 3 mm. Examples occur, however, having as long teg- 

 mina as are found in fasciatus s.s., which condition is more fre- 

 quently met with in the southern portion of the range of the insect 

 and has been given the name productumhy Morse. As further dif- 

 ferences are wanting to distinguish such material, we are obliged 

 to place this name in the synonymy of the present form. The 

 phase having very long tegmina and wings is represented by the 

 following material before us: 2 d", Mountain Home, Idaho; 1 

 d^, 2 9 , Shoshone, Idaho; 1 d', Milford, Utah; 1 d', Reno, Ne- 

 vada; 2 d^,Alamitos Bay, California, and 1 d^, Los Angeles, 

 California. An almost intermediate condition is shown in a num- 

 ber of individuals from Council Crest and Divide, Oregon, and in 

 two d" from Milford, Utah. 



In life the present race is normally quite as green in general 

 coloration with abdominal markings brighter than in typical fas- 

 ciatus; the following field note taken from fresh material at Sho- 

 shone and Mountain Home, Idaho, demonstrates this very clearly 

 — "Abdomen with a medio-dorsal band of vandyke brown, wider 

 cephalad, narrowing gradually caudad, bordered by lemon yellow 

 bands about half as wide. In the males the rest of the abdomen is 

 grass green, in the females these lemon yellow bands are in turn 

 bordered on each side by very narrow bands of vandyke brown." 

 The large series before us, though otherwise in excellent condi- 

 tion, is almost without exception much discolored and faded, the 

 cerci of the males retaining a green coloration in only a few cases. 



The genicular areas of the caudal femora are not darkened ; the 

 genicular lobes of the same are normally bispinose; the ventro- 

 external margins of the caudal femora are normally unarmed, 

 very small (usually microscopic) spines are present in one hun- 

 dred and fifty-two specimens examined as follows: 

 Number of spines, 0-0 0-1 0-2 

 Number of specimens, 146 5 1 



This shows 3.9% of the material to have these margins armed 

 with such adventitious spines. 



The ovipositor length is as follows: Mountain Home, Idaho, 

 11.2-12.6; Soda Springs, Idaho, 9.2-10.7; Council Crest, Oregon,
