Gryllus domesticus Linnaeus. 



This species, accidentally introduced by man from Europe, has 

 been recently recorded by us 162 from "Carolina" and Roswell, Albany 

 and Thomasville, Georgia, within the territory at present under con- 

 sideration. 



Miogryllus verticalis (Serville). 



The American species of this genus have recently been fully 

 studied and reported upon by the junior author. 163 



Material from the present collections from College Park and 

 Plummer's Island, Maryland; Washington, District of Columbia; 

 Falls Church, Virginia; Raleigh and Goldsboro, North Carolina; 

 Columbia, South Carolina; Clayton, Sand Mountain, Trenton, Au- 

 gusta, Tybee Island, Mixon's Hammock in Okeefenokee Swamp and 

 Billy's Island, Georgia, and Jacksonville, Atlantic Beach and Mari- 

 anna, Florida, is treated in that paper. In addition we now have 

 the following specimens: 



Raleigh, North Carolina, late VI, 1911, Hebardville, Georgia, V, 15, 1915, (H.), 

 (C. S. Brimlev), 2 9,1 macropter- 1 juv. 9 , 1 very small juv. 9 . 



ous, 16 " [Brimlev Cln.]. Billv's Island, Ga., V, 16, 1915, (H.), 



' 1 juv. 9. 



Gryllodes sigillatus (Walker). 



Though not as yet known from Florida as far north as the region 

 treated in the present paper, this species is apparently rapidly 

 extending its distribution northward. 



It has been reported by Davis from as far north in Florida as 

 Lakeland, and recently the junior author found it widely distributed 

 in that town, particularly about grocery stores, where, on May 21, 

 1915, a single male was taken to verify tljis observation. 



(Ecanthus niveus (DeGeer). 



Cranberry, North Carolina, VIII, 1896, (H. Skinner), 1 o", [A. N. S. P.]. 



This species has been very widely discussed in past literature, 

 principally owing to its economic importance, but very general 

 confusion with both 0. exclamationis and 0. angustipennis prevents 

 the use of the majority of these records in distributional studies.

164 This specimen is of particular interest in being the first macropterous 

 example of the species to be reported from temperate regions. Four other 

 macropterous specimens are known from the tropics, the type and three individ- 

 uals of the series of one hundred and twenty-two examples which were before 

 the junior author at the time the genus was revised. In the present example 

 the internal face of the cephalic tibiae bears a but weakly defined tympanum; 

 the measurements are: length of body 13.7, of pronotum 2.3, of tegmen 6, of 

 wing 16.7, of caudal femur 9, of ovipositor 10.3 mm.
