Fontaria clara sp. nov. 



This form is characterized in having the gonopods of the male of a 

 very distinct type. The proximal end of the second or principal division 

 of each gonopod is densely hirsute; the blade is in two branches, which 

 are smooth and strongly chitinous; of these the ectal one curves first 

 proximad (dorsad) on the ectal side of base and then bends in a semi- 

 circle and extends ventro-caudad subparallel with its basal portion, and 

 is distally acutely acuminate; the mesal branch is larger and extends 

 ventrad or ventrocaudad in general, with a slight double or sigmoid 

 curve, the tip, which is flattened from side to side and is acute, weakly 

 hooked or recurved. The basal process springs from the dorsomesal 

 side of the base of the principal process; proximally it is flattened and 

 narrows to an acute tip distad, somewhat twisted and crossing over 

 the process from the other side, much shorter than the other processes. 



When in full color the dorsum is very dark, black or nearly so, with 

 the carinae sharply contrasting by their lighter, in preserved specimens 

 yellowish color. First tergite lighter along anterior border, but not 

 along the posterior. Under surface and legs yellowish. 



Vertigial foveolae two on each side. Vestigial sulcus ending below 

 at the angle of an inversely v-shaped transverse sulcus between the 

 antennae. 



Sternites unarmed. Processes of coxae of second legs in the male 

 stout, clavate, distally truncate. 



Locality. — La.: Creston. Type, a male, taken March 5, 

 1915. Other specimens taken Feb. 25, 27 and 28, and March 

 21, 1915.
