Xiphidion fasciatum (DeGeer). 



This widely distributed species is represented by a series of ninety- 

 five specimens, all from Thomasville. The months represented are 

 June, August, September, October and December (one specimen), 1903. 



I took but one specimen of this species, that in December, 1903. It 

 was procured among tall grass in a swampy hollow. (M. H.) 



Xiphidion brevipenne Scudder. 



Three females and four males of this species from Thomasville have 

 been examined. They were taken in August, September, October 

 and December, 1903. 



The single specimen of this species which I took in December, 1903, 

 was secured in the damp undergrowth of the pine woods near a 

 "branch." (M. H.) 



Xiphidion saltans Scudder. 



Two females and five males of this species are included in the mate- 

 rial studied. They were taken at Thomasville in September, October 

 and November, 1903, the one taken in the latter month being from 

 meadow land. 



Odontoxiphidium apterum Morse. 



This recently described genus and species is represented by a series 

 of twenty males and twenty-two females, all from Thomasville, taken 

 in September, October, November and December, 1903. Those indi- 

 viduals bearing information in addition to the date and locality are 

 labelled as having been taken in imdergrowth in pine woods. The 

 series agrees very well with the description, exhibiting the color varia- 

 tion noted in the original series. 



The specimens which I took of this species were all captured in the 

 wire-grass of the pine woods. Although active, they were easily cap- 

 tured. (M. H.) 



A male specimen of this species from Brunswick, Glynn county, 

 Georgia, taken September, ISSl, is in the collection of the Academy. 



Atlanticus gibbosus Scudder. 



As far as can be determined from the very inadequate description 

 and the immature condition of the majority of the twelve specimens 

 examined, I should refer the representatives of this genus to gibbosus. 

 But one individual, a female, is fully grown, the others being in such 

 condition as make them almost useless for study. The dates repre- 

 sented are March 16, 17, 22, 23, 24 and 29 April 9, July 23 (adult) and 

 December 10, all from Thomasville. 



In December, March and April I have found immature individuals 

 of this species plentiful in the pine woods, where they live among the
