1918] Chamberlin — Myriapods from Nashville, Tennessee 29 



Basal lobe of each gonopod strongly setose on mesal side. Ex- 

 terior division with setae on posterior edge over basal and middle 

 region; the branchis constricted above here into a slender blade of 

 uniform width until the next to the distal fifth of length over which 

 it is expanded to nearly double the >\adth and then again narrows 

 to a tongue which at its distal end is attenuated into a slender, 

 distally bristle-like tip. About the distal three-fifths, or less, of 

 the exterior blade is strongly bent upon itself roughly into all-shape, 

 with the slender tip at right angles to the arm bearing it. The 

 basal spine short, slight, curved, acute. 



Length about 39 mm. Width 10 mm. 

 Locality. Glendale Hills, south of Nashville, April 21, 1917. 



Two adult males, one adult female and four immature indi- 

 viduals. Closely related to F. rileyi Bollman, described from 

 Macon, Georgia. 



25. Fontaria mimetica sp. nov. 



General color at present dusky brown with the carinse and bor- 

 ders of somites yellow. Of reddish caste and probably red in life. 

 The posterior band of color usually widest at middle. The first 

 somite with anterior as well as posterior border of the lighter color. 

 Head light at sides and below level of antennse. Antennae deep 

 reddish brown or chestnut. Legs yellowish. 



Body conspicuously narrowed cephalad over the first four so- 

 mites. Carinse very much as in glendalea but with the caudal 

 angles in general more produced. 



Repugnatorial pore dorsal in position, widely removed from 

 lateral edge. 



Vertigial sulcus distinct. Occipital foveolse 2 -f 2; antennal and 

 clypeal 1+1- 



Sternite of third somite in male with two processes fused into a 

 single conspicuous median body which is somewhat constricted at 

 base. Fourth sternite with two separate subconical processes. 

 Coxae without spiral process aside from those giving exit to the 

 genital ducts on the second pair. 



Fifth sternite with two low, rounded eminences. 



The general form of the gonopods as in glendalea, strongly 

 coiled nearly into a complete circle open below, but the exterior 

 division much broader, at first cylindrical, then flattened and near
