high-pitched zeee-zeee-zeee. Along the Atlantic coast the authors 

 have found the species under boards and various other debris on the 

 ground, usually along the edge of, or in forest growth, and almost 

 always in very small numbers. Once, however, a locality was 

 examined where the little insects were present in countless numbers; 

 this was on St. Simon's Island, Georgia, where myriads were found 

 jumping about among the dead leaves and very few low plants and 

 grasses growing on the sandy soil under live oaks. Professor Bruner 

 has stated that the synonymous C. borealis is common in Nebraska 

 among dry grass and under boards on sandy soil. 



Synonymy. — As we have before us one male and fifteen females 

 of the typical series of Cycloptilus borealis Bruner, we are enabled to 

 refer it unhesitatingly to the present species. There are no differ- 

 ences between these specimens and the type and allotype of squamo- 

 sum, except in the coloration of the scaly covering which in the 

 present species is exceedingly variable. We find Scudder's measure- 

 ments to be accurate, while those given by Bruner in the original 

 description of borealis are quite different from what we find to be the 

 case in the typical series, which in size and proportions can in no way 

 be separated from squamosum. 



Remarks. — In the series of females before us, the distal section of 

 the margin of the subgenital plate varies from a type which is arcuato- 

 convergent laterad with the distal section of the margin complete, 

 to one which has the distal section of the margin broadly emarginate, 

 this emargination flanked laterad by acute spiniform angles. The 

 majority of specimens from the Atlantic coast have this emargination 

 present, while it is absent in the majority of western specimens, but 

 an examination of the series shows that it is not constant and that 

 in this species the entire form of the subgenital plate is exceedingly 

 variable in the female sex, while in the male it is simple and broadly 

 arcuate. 



Specimens Examined. — 215; 83 males, 115 females, and 17 nymphs.
