NO. 1530. THE BECTICINM OF NORTH A MERICA— CA UDELL.

lection contains nine males and seven females, some marked types, but 

 erroneouslj' so. 



Prof. A. P. Morse, who has taken this species in the west, says it is 

 found in deciduous woodlands and shrubl)ery, hopping about on the 

 carpet of fallen leaves, with which its coloration agrees. This is prob- 

 al)ly true of the other members of the genus. Some nymphs referred 

 with doubt to this species have the lateral carin;v of the pronotum 

 nearly parallel. 



At Eureka, California, July a, llHHj, 1 took three adult males and 

 one female nymph. They were in just such a locality as described by 

 Morse. The males were stridulating and were quite numerous, being- 

 heard in the grass along the road in open ground well removed from 

 woodland, even in the edge of town. The male commences to stridu- 

 late about dusk, or a little before, and the sound is similar to that 

 made by a person gritting the teeth together, but in a higher key. 

 The chirp is repeated from a few, three or more, to as many as about 

 thirty times, the largest number noted by me being twenty-nine, while 

 the fewest, when the insect was seemingly undisturbed, was three. 

 The rapidity of the beats was at the rate of about one hundred a 

 minute. The singer was usually found among dead leaves lieneath 

 briars or shrubs. They do not leap readily, seeming to depend for 

 protection on their surroundings rather than ])y their activity. So well 

 do they harmonize with their surroundings that it is almost impossible 

 to discover them as long as they remain quiet. When their retreat is 

 beneath a bunch of briars, as is often the case, they are i)ractically 

 safe from capture. I took the typical form and the \ar. ^^/c'^^rra^^cz^ 

 singing within a few yards of each other.
