and the prominences in consequence more and more bifid, so that 

 the crest on the 2nd is divided to the base and consists of a right and 

 left half ; the surface of the segments between the base of the dorsal 

 and the base of the lateral keel furnished with a longitudinal series 

 of three conspicuous tubercles. 



Sterna very narrow, so that the bases of the legs are nearly in 

 contact in the middle line ; anal sternite triangular. 



6 . All the legs thick, especially those in front of the seventh 

 somite ; copulatory feet with basal segment enormously enlarged' 

 hairy, punctured and sub-tuberciilar, the distal segment pale coloured, 

 slender, blade-like, in repose projecting obliquely inwards and back- 

 wards, crossing its fellow of the opposite side. 



Length 10'5 mm.

This genus was referred to the Iiilidce by both Gervais and Karsch, 

 both authors stating that it differs from luliis in the structure of its 

 eyes. 



The type of the genus, i. e., 8t. hioculatus from Colombia, is in the 

 collection of the British Museum, and is beyond all question con- 

 generic with the specimens described below. 



The characters that I believe to be of generic value are as follows: — 



1. The eyes are situated behind the antennae and consist of either 

 one or two, simple, round ocelli. 



2. The antennae are exceedingly long, slender, and not incrassate. 



3. The coUum is small like that of Lysiopetalum. 



4. The body is compressed, and each somite is divided above by 

 a longitudinal sulcus. 



5. The pedal laminEe are all free. 



6. The pores begin upon the 5th somite. 



It will thus be seen that in characters 2, 4, 5, and 6, the genus 

 agrees with Lysiopetalum, and differs from the typical Itilidce, In 

 character 1 it resembles neither.
