tooth, and an internal snl (terminal ridge; dorsal process with two small 

 teeth; external article with a large basal tooth, a smaller tooth toward 

 the apex and apparently two minute apical teeth. 



Scutum (Fig. 1) dark reddish brown with an extensive white pattern; 

 oval, slightly constricted at eyes; capitular emargination moderately 

 deep; scapular angles narrowly rounded; cervical grooves distinct, but 

 not deep, first converging then diverging posteriorly, not reaching to 

 edge of pseudo-scutum ; marginal groove shallow, marked by a row of 

 large punctures, a very few rather small punctures elsewhere on scutum; 

 festoons prominent; pseudo-scutum outlined with a broad white band, 

 white between cervical grooves, more broken on postero-median part of 

 pseudo-scutum; two submarginal stripes running from pseudo-scutum to 

 third festoon on either side, these are joined to an interrupted marginal 

 band which becomes continuous, though narrow, posteriorly, running 

 around entire posterior margin of festoons; two submedian stripes run 

 backward from pseudo-scutum, these diverge posteriorly and join the, 

 submarginal stripes at the first festoon, they are also connected with the 

 submarginal stripe anteriorly ; two submedian loops of white extend from 

 the point where the submedian stripes begin to diverge to the fifth and 

 seventh festoons; all white markings are interrupted by numerous small 

 red points. 



Legs (Figs. 1,4) dark reddish brown with much white dorsally, tarsi 

 with but a trace of white; coxae and basal joints of legs with numerous 

 rather short pale hairs; coxae I with internal spur slightly longer than 

 external; coxae II and III with inner posterior angles upturned; apical 

 spines on coxae II, III and IV about equal in length, those on coxae I V 

 slightly more slender than on any of others; trochanter I rather long, 

 much enlarged distally, forming a postero-ventral knob, produced antero- 

 dorsally into a broad sharp spur; trochanter II less enlarged distally, 

 III not noticeably enlarged and IV with a slight flaring internal rim ; 

 femur IV with a long sharp anterior projection at its articulation with the 

 trochanter, also a shorter less sharp posterior prominence; narrowed 

 toward articulation with trochanter, this narrowed portion of femur 141m 

 long, total length 1.088 mm.; femora with five ventral teeth, three of 

 these small, apical one long and sharp; length of tibia 932m, with two 

 rows of ventral teeth, three moderately sharp teeth in anterior row and 

 four less sharp ones in posterior row; metatarsi 775m long, with four 

 rather blunt teeth ventrally, two along the median line near the middle 

 of the segment and two opposite each other at its distal end ; tarsi I V 

 731m long, tapering to tip, with a subapical ventral spur and a long 

 recurved apical spine; pulvilli elongate oval; total length of pulvilli IV 

 273m; claws long and slender. 



Stigmal plates (Fig. 5) oval with a very long narrow postero-dorsal pro- 

 longation; greatest dimension from antero-ventral angle to extreme tip of 

 prolongation 617m; entire plate narrowed toward the prolongation; the 

 chitinized margin is wide, especially along the external lateral angle and 

 near the tip of the prolongation where the margin widens to form a small 

 boss ; goblets rather large, widely separated, covering most of the surface
