GONOLEPTES SCOTIUS/ sp. IIOV. 



Plate 3, fig. 6-8; Plate 4, fig. 1-2. 



Body throughout black of brownish cast, lines of white along cara- 

 pace caudally and laterally and bordering tergites and sternites of 

 abdomen. Caudal edges of coxae IV also bordered with white. 

 Carapace under lens seen to be not densely mottled with small lighter 

 spots in head region and over border behind. The legs similarly 

 mottled but light spots more numerous, the trochanters of all legs 

 and the tarsi of third and fourth legs and in some also of first and 

 second lighter in color. Palpi paler than legs, the spots being larger 

 and in part confluent. 



Body relatively narrower than in enoplus, the greatest width of 

 carapace being much less than the total length of body and about 

 equal to length of carapace. The general form of body shown in 

 Plate 3, fig. 6. 



Carapace with four transverse sulci of which the first is deeper and 

 is angulate at middle in the usual way, bifurcate on each side toward 

 end; second sulcus angularly bent forwards at middle, the third 

 toward each end bending back caudoectad; a strongly impressed 

 longitudinal median sulcus between first and second transverse sulci 

 which is more weakly continued between second and third and third 

 and fourth. A transverse sulcus also indicated in line with caudal 

 edge of eye-tubercle. Eye-tubercle sharply defined, moderate in 

 height, wider than long, bearing a few small but distinct tubercles 

 with paired ones present in place of the cones of enoplus rounded or 

 boss-like, these two smaller than eyes but larger than other tubercles. 

 Median portion of head just in front of eye-tubercle elevated and the 

 anterior border each side of this part elevated as usual. Lower 

 frontal margin excavated for mandibles as usual ; upper frontal margin 

 without distinct teeth at each rounded lateral corner but with rounded 

 boss at end of ridge there. From cervical region caudad on each 

 lateral border of carapace the usual series of tubercles ; a tubercle-free 

 area opposite the third sulcus and behind this about three noncontigu- 

 ous larger tubercles and then along caudal margin a series of smaller 

 tubercles which are widely separated and irregularly spaced. The 

 conical processes at posterior end of carapace long, acuminate, close
