1918] Myriopods from Georgia and Louisiana 371 



Euryurus louisiana sp. nov. 



In general appearance much like Euryurus erythropygus (Brandt) 

 but appearing somewhat more slender and with the red carinse more 

 elevated. The carinse have the tooth at the anterior comer propor- 

 tionately larger and caudad of this less bulging ectad, the swollen border 

 narrowing cephalad as in erythropygus; the caudal margin of the anterior 

 somites is wholly smooth, not so irregularly crenulate or bluntly denti- 

 culate as usual in the latter species. The vertigial sulcus of the head 

 ends in a rather deep depression at the level of the upper edges of the 

 antennal sockets. 



The gonopods of the male are strikingly different from those of 

 erythropygus. The proximal division of each is very short, sub- 

 cylindrical and glabrous. The distal division about its stouter proximal 

 end extends at an angle ventrocaudad as a stout subcylindrical body 

 which is subtruncate at the free end, which is darker and more highly 

 chitinized; distal end concavely depressed or grooved, with a short, 

 blade-like branch arising from the dorsomesal comer and curving a 

 little dorsad of ectad above the main branch, the outer edge of which it 

 does not reach. The enlarged base of the distal division is concavely 

 depressed on its mesal surface, the depression densely clothed with long 

 bristles. Midway between this basal depression and the distal end is a 

 smaller depression similarly setose. The division is also less densely 

 setose over the remaining surface excepting the chitinous distahend. 



Length about 25 mm. 



Locality.— La.: Creston. Feb. 27, 1915. One male. Also 

 two broken females taken March 5, 1915. 



Euryurus erythropygus (Brandt). 

 Several specimens taken near Creston, March 5, 1915. 



Fontaria lampra sp. nov. 



This species seems nearest to F. himaculata (McNeil), described from 

 Pensacola, Fla. The male gonopods are in general similar but the 

 proximal common stalk of the principal, bifurcate spine, is relatively 

 much longer, being as long as or longer than the branches; the shorter 

 or inner branch is much broader, being as broad as the other, is slightly 

 clavately expanded and at tip narrowed to a straight acute process, 

 which does not curve toward the other branch. The process as a whole 

 is bent upon itself almost at right angles at the level of bifurcation. 

 The anterior or basal spine which in bimaculata is nearly as long as the 

 principal one, in the present species is very much shorter, less than half 

 as long, slender, acute, moderately curved. 



The color is a very dull brown, the carinae somewhat lighter, though 

 not much contrasting in the types. In some the color is deep, almost 

 black, with the carinse not paler. A mid-dorsal dark stripe sh6ws in 

 some.
