SUBFAMILY I. GRYLLOTALPIXJE. 645 



the eggs are sometimes found in masses of (JO to 100, adhering 1o 

 the rootlets of various plants. These eggs are spherical, white or 

 almost colorless, and have a diameter of 0.7 mm. The young are 

 active leapers, and are said to be about three years in reaching 

 maturity. On July 19, 1894, a hundred or more of the half- 

 growii young were captured in a small meshed seine while col- 

 lecting fishes in a small stream in Montgomery County. They 

 were evidently burrowing in the soft mud close to shore or per- 

 haps in the mud beneath the shallow water. Just a year later a 

 number of young were also taken in a seine from the waters of 

 the outlet of Lake Wawasee, Kosciusko County- Since they feed, 

 during their lives, mainly upon the tender roots of various plants, 

 they are necessarily very injurious and it is fortunate that with 

 us they are not more common than they are. 



The known range of this mole cricket is a very wide one ex- 

 tending from British America to the southern part of South 

 America, Perty's types having been from Minas Genps, Brazil. 

 K. & H. (1916, 277) first placed the G. boreal in of Burmeister as a 

 synonym of hc.ru dactyl a and as Scudder and Saussure in their 

 keys separated the two only by the length of the inner wings and 

 the form of the projection at the base of the second lateral dactyl 

 of the fore tibiae, the two names are doubtless synonymous. The 

 long-winged form, Columbia Scudder (1869a. 26) was first placed 

 as a synonym of borcalis by me in 1903. Other svnonvms of

In Florida G. liejcaclactyla has been taken by me only at St. 

 Augustine (at light), Ormond, Lake Okeechobee and Dunedin, 

 though its runways have been noted at almost all collecting sta- 

 tions. Elsewhere in the State it has been recorded only from 

 Leon County, where Hebard found one in a cherry tree, Enterprise 

 and Lake City. About Dunedin its runways occur in numbers 

 around the numerous small lakes and ponds, and on March 11, 

 1918, I took nine males and three females by digging in the muck 

 on the margin of one of these. The specimens thus taken were all 

 brachypterous and were much more sluggish in their actions than 

 when uncovered in a runway. They were smaller and darker than 

 those from Indiana and the terminal joints of the palpi were also 

 distinctly paler. When first uncovered the smooth silken-like 

 luster of their surface was notable. To it not a particle of mud, 

 muck or water adhered- There is little doubt but that this mole 

 cricket occurs in numbers in all parts of the mainland of Florida
