SUBFAMILY I. TRYXALIN.K. 197 



far west as Greenville, Alabama, and Agricultural College, Miss. 

 Kirby (1910, 101) gives "Florida and Mexico" as its habitat. I 

 can find no other record of its having been found in the latter 

 country.

A so-called geographic race or subspecies of R. brecipcnne was 

 described by K. & H. (1912, 240) as 7?. b. p<>ninxnl<n-c (Fig. 74), 

 they stating that it differs from typical brrripcnnc "in the longer 

 head with much more produced rostrum and more concave face, 

 longer antennae, pronotum with shallower lateral lobes, more 

 linear and usually shorter tegmina, longer and more slender cau- 

 dal femora and more delicate, shorter, genicular angles." All the 

 distinctions as given are comparative only and may be found in 

 any large series of specimens taken almost anywhere in Florida. 

 They later (1914d, 103) state that two males and four females 

 taken at Lakeland, Fla., "are absolutely intermediate between 

 typical brci'ipenne and b. peninsula re in character." Notwith- 

 standing this admission, they state in their latest mention of R. 

 brci'ipennc (1916, 155) that "in central Florida the species inter- 

 grades with its geographic race R. brevipenne peninsular e" I 

 have given above the distinctions of peninsulare as set forth by its 

 authors in order that the future student may apply that name to 

 his southern Florida specimens if he so desires.
