of the antennal joints, etc., bright purple or magenta color, and 

 especially by the absence of the united or approximated, large, 

 round, lake-red or purple-red spots on the dorsal side of the first 

 abdominal segment. But in ,5". brasiliensis this segment has a pair 

 of equally large and conspicuous spots of brighter red or magenta, 

 wide apart, or about midway between the center and the margin, 

 where there are also ill defined dull-reddish or light brown spots 

 in many specimens of the common species, in addition to the 

 median pair. 



S. braziliensis differs, however, in many other respects, especially 

 in having the whole upper surface more coarsely and roughly 

 granulous and covered much more closely with longer stiff, erect, 

 setose hairs, so abundant as to obscure the granules. The under 

 parts of the carapace, antennal plates, legs, and sternum are more 

 granulose and more hairy. The legs are more slender and more 

 sharply carinate on the dorsal surface, and lack the round, purple 

 spots characteristic of the common species. 



The antennae are longer, especially the distal segment, and their 

 outer edges are more strongly crenulated, but the distal and inner 

 margins are not so strongly toothed. The second to fourth abdom- 

 inal segments are subcarinate, but not humped. The lateral lobes 

 are much more prolonged ventrally, not so thick, and the margins 

 are more - strongly toothed. The fifth and sixth segments are 

 longer, but not so wide. 



It was first described from a Brazilian specimen by Miss 

 Rathbun, in 1906.*

PLATE V, FIGURE i. PLATE VI, FIGURE i. 



Carapace coarsely granulated, longer than wide, a little wider in 

 the middle than at the orbital angles ; subtruncate in front ; 

 external or orbital margins form nearly a right angle terminating 

 with an obtuse tooth ; cervical notch and groove well marked ; 

 eight or nine small, nearly equal, obtuse denticles on the margin, 

 in front of the notch, that of the angle somewhat larger ; margins 

 behind the notch with numerous small denticles, scarcely larger
