(MCZ), collected by V.E. Shelford, 10 July 1942, from station 1 1, De La 
Howe Forest, McCormick Co., South Carolina. 
Diagnosis.— With the characters of the genus. 
Holotype. —Length 56.1 mm, width 13.0 mm, W/L ratio 23.2%. 
Paranota depressed, creating a high height/width ratio of 60.3% at mid- 
body. Body essentially parallel sided from segments 6-14, tapering at 
both ends as indicated by following segmental widths:

Color in life unknown (see topotype description). Head capsule 
smooth, polished; width across genal apices 5.4 mm; interantennal 
isthmus broad (1.9 mm), smooth; epicranial suture shallow but distinct. 
Antennae relatively short, extending only to caudal edge of second 
tergite, becoming progressively more hirsute distally; first antennomere 
subglobose, 2-6 clavate, 7 short and truncate; relative lengths of anten- 
nomeres as follows: 2>3>4>6>5>1 >7. Genae not margined 
laterally, trace of medial impression, ends broadly rounded and ex- 
tending slightly beyond adjacent cranial margins. Facial setae as follows: 
frontal 1-1 (impressions only, setae not seen), genal 1-1, clypeal about 9- 
9, labral about 12-12. 
Dorsum typical for family. Paranotal corners rounded on segments 
1-6, becoming slightly more distinct on 7 and progressively more so 
caudally. Peritremata virtually flat on segments 1-7, only slightly elevated 
above paranotal surface; higher and more distinct on remaining seg- 
ments. Ozopores small and indistinct, situated near middle of paranota. 
Sternum of segment 4 produced into large, apically divided process 
(Fig. 3), subequal in length to width of adjacent coxae; sternum of seg- 
ment 5 produced into two small digitiform lobes between fourth pair of 
legs and two knoblike processes between fifth pair. Postgonopodal sterna
