740 FAMILY VIII. GRYLLIDJB. THE CRICKETS. 



devour his tegniina to keep him from calling other females about 

 him. It is more than probable, however, that the mating of the 

 sexes takes place in a similar manner to that of the white tree 

 crickets (Oecanthus), the females gnawing away the tegmina of 

 the males in order to more readily reach the alluring glands which 

 lie beneath. The openings of these glands, located on the dorsum 

 ot the metathorax, are visible in dried specimens at hand. 



In Florida I have found H. agitator more common than in In- 

 diana, a few specimens having been secured at most of the collect- 

 ing stations. About Dunedin it is taken in winter more com- 

 monly in dense hammocks where it hibernates in bunches of dead 

 leaves which have lodged in the thick tangles of vines and shrubs. 

 The males at that season probably represent a late fall brood 

 which have not yet mated as the tegmina are mostly intact, while 

 those taken in spring have them partially eaten away. It has been 

 recorded by other collectors from numerous localities throughout 

 the State, mostly under the name H. qua drat us Scudder (ISGSb, 

 140), a form relegated to synonymy by both Scudder and Saus- 

 sure, but restored as a valid species by K. & H. (1905, 52), and 

 again reduced by them to a southern race (1916, 309.) No dif- 

 ferential characters which can be used in a key can be found in 

 comparing southern Indiana and Florida specimens, some of the 

 former being fully as large with tegmiua and hind femora as long 

 as those from Dunedin. As R. & H. (loc. cit.) admit that the 

 two so-called races merge in North Carolina and at the most 

 u show little definite differentiation," I do not consider the name 

 qudflrntus worthy of retention. The known range of agitator, as 

 here recognized, extends from Long and Staten Islands, N. Y., 

 west to southern Indiana and eastern Nebraska and south and 

 southwest to southern Florida, Cuba and Brownsville, Texas. 

 Uhler (1864) says that about Baltimore it inhabits grape vines 

 and dense shrubbery and is found fully developed about the mid- 

 dle of September. The Omrliari* nlilcn McNeill (1891, 9) is a 

 synonym of H. agitator. 



( ). HAPITHUS VAGUS Morse, 1916, 178. 



Very large and robust. Dull yellowish-brown, thickly and irregularly 

 mottled with darker brown and fuscous; dorsal field of tegmina of female 

 often with three or four dusky lines along the veins. Tegmina nearly or 

 quite covering the abdomen; wings as long as tegmina. Hind femora 

 relatively short and stout. Ovipositor shorter than hind femora, its apex 

 armed beneath with one large and several small blunt teeth. Length of 

 body, $ and $, 13 15; of tegmina, 9.5 10; of hind femora, 10 12; of 

 ovipositor, 8.5 9 mm.
