than the longest lateral setfu. The apical seta is slightly 

 lono-er than the distal lateral ones. 



Length. — 3 to 4*2 mm. 



Locality. — Island Koh Chang (Gulf of Siam)^ under 

 stones^ January 17th, 1900 (Dr. Th. Mortensen), 



Remarks. — This species is sharply separated from the 

 following one, S. pan per at a, by the characters pointed out 

 in remai-ks on the last-named species; from the other species 

 of the genus it is easily distinguished b}'^ the characters 

 limiting Group III,, and put forward above on pp. 25, 26.

Material. — Many specimens from a rather small island. 



Head. — Seen from above it is moderately narrow in pro- 

 portion to the length, with the lateral margin rather flatly- 

 arched without any angle; the longest lateral seta as long as 

 or a little longer than the breadth of the basal antennal 

 joints. The central rod is rather short, the anterior part 

 with its branches being not visible, and posteriorly it is 

 connected with the vertex of a triangle which is not very 

 conspicuous, and limited on tlie sides by the oblique rods, 

 which are feebly developed. 



Antenna}. — The number of joints varies from nineteen to 

 thirty-two. Seen from the side the basal third of the 

 antennre, especially the second to the sixth joint, is thick- 

 ened, but in a somewhat less degree than in Scut, crassi- 

 cornis; on the inner side of the second to the sixth or 

 seventh joint two or three seta3 on the inner side are very 

 elongate, the longest of them two and a half to throe times 

 longer than the outer seta?, and besides nearly vertical on the 

 longitudinal axis of the antennas. The secondary'- whorl 

 begins below on the seventh or eighth joint, but is developed 

 only on the ventral side of all the following joints (fig. 2 a). 

 The seta) in the central whorl are rather long on the upper 

 side and considerably shorter below. Near the distal two 

 thirds of tlie joints a rather robust, conical, sjiiall rod is
