446 RKTOKT OF STATE GEOLOGIST. 



The day note of the male of lalipennis is louder than that of any 

 other species. I have heard it when HO feet distant; have traced it 

 up, and found the musician beneath a leaf or on a post in the angle 

 of a rail fence, industriously sounding his cymbals. The note is 

 kept up for 20 to 30 seconds, and is then succeeded by a pause of 

 about five seconds, when it is begun once more. Dr. Riley has writ- 

 ten of it, probably of the night song: "The shrill of latipennis is 

 continuous and recalls the trilling of a high-pitched dog-whistle in 

 the distance. The key varies, however, and is sometimes much less 

 high and more musical than at others. The commingled shrill of 

 this species recalls also the distant croaking of frogs in spring. The 

 broad wings are thoroughly elevated during the act, or even bent 

 forward, and the vibration is so rapid that there appears to be no 

 motion."

Both sexes of this species are in color ivory white, more or less 

 tinged with a delicate green, especially in the female. The top of 

 head and basal joint of antennse are sometimes sui- 

 Hl fused with ochre yellow, while on the lower face of 



l\ each of the two basal joints of the antennae is a small 



\^Xr round black spot. The tegmina are almost twice as 



long as the abdomen and the inner wings equal or 

 joints of anton ^I'ghtly cxcccd them in length. The ovipositor of the 

 mvoi(Ecanthns female is short, perfectly straight and usually tipped 

 with black. The maxillary palpi are longer in this 

 thiin in any other species of the genus, and the wing covers of tlie 

 male are broader in proportion to their length than in any other ex-
