CHAMBERLIN: HENICOPIDAE OF AMERICA NORTH OF MEXICO. 13 



Three last pairs of legs appearing as long, closely appressed buds, 

 of which the first, in one specimen, is very faintly segmented distad 

 of the coxa, the others more indistinctly so; pale; without trace of 

 hairs excepting one long ventral bristle on the relatively large coxa 

 of each leg. 



A single coxal pore present on each coxa of twelfth legs, this a little 

 pigmented. 



Anal glands showing very distinctly. 



Anal segment with a pair of short bristles immediately beneath 

 glands and two pairs of very long setae caudad of the glands, the two 

 bristles of each pair being near the median line and crossing each other 

 obliquely. 



Length cir. 3 mm. 



New Orleans, var. a. 



LOCALITIES. Mississippi (Byram ! Holly Springs !) ; Louisiana 

 (New Orleans! var. a); Alabama (Jackson!). 



Variety a. The specimens from New Orleans are uniformly darker 

 than those from Mississippi and Alabama, appearing to be a little 

 more strongly chitinized, the darker extremes of coloration noted in 

 the description of the adults above being met with in these individuals. 

 The tarsal and tibial joints of posterior legs are on the average also 

 relatively more slender than in the others. Otherwise no differences 

 could be detected, however, and complete intergradation is likely 

 to be found. 



NOTE. The record of this species from Hot Springs, North Carolina, 

 given in connection with the original description was an error, all 

 specimens studied from that locality belonging to the next species. 

 The measurement of 7.5 mm. given as the maximum length in the 

 description mentioned pertained to a small specimen of the latter 



species, L. plus.
