This is a large species like S. mm i/nuitus and S. iim ir/fius. From those species 

 it is at once separable in not having the second segment angularl\ produced helow 

 the first tergite, hut instead evenly convexly rounded . 



Also unlike those species the segments are anteriorK- reddish or somewhat chest- 

 nut, while the caudal border is colored with a broad deep brown or blackish band, 

 the red and black stripes in general appearing nearly eipjal. Along the caudal is a 

 deeper black line. Over the repugnatorial glands are a series of small black trian- 

 gular spots. The ana! tergite is reddish brown excepting caudal, where Idackish. 

 First tergite blackish over a chestnut background, the anterior margin a clearer 

 chestnut. Anal valves reddish brown. Legs brown. Head blackish above and to 

 below antenna;; labrum chestnut. 



The eyes are large, somewiiat in the form of a right triangle wiili the bypothe- 

 nuse anterior in position. Ocelli numerous, about sixty-five in number, arranged in 

 seven slightly curved series paralleling the caudo-dorsal edge of the eye. \'estigial 

 sulcus ending nearl\ on a le\'el with the upper borders of the antennal sockets. Sides 

 of head and mandibles somewhat tlejnes'ed, hut not liistinctK furrowed for the re- 

 ception of the antenna?. 



Tile anteroventral corner of the first tergite is carried moderately forward, the 

 corner being separated off from the rest of the plate by a strong sulcus extending 

 from near the anterior margin opposite the eye obliquely caudoventrad to the upper 

 level of the rounded caudoventral corner. C'ephaloventral of this main sulcus are 

 three others, of which the uppermost does [k t extend over the cephalic part, in addi- 

 tion to the finer margining sulcus ivhich parallels the lower margin and the lower 

 part (if the anterior margin. 



'I'he other somites are striuigly striate below the level of the repugnatorial pores. 

 The repugnatorial pores are small; each is widely separated from the sulcus which 

 opposite it curves widely and Init weakl\ forward. 'I'he anal valves ha\'e the mesal 

 borders very strongly elevated. 



The number of somites in the type (female) is sixty-six. 



Length in the neighborhood of 130 mm.; width, S.5 mm.
