This species is separated from the Dominican R. leucostigma with 

 considerable doubt and may ultimately have to be merged with that 

 form. It agrees with the latter quite closely in structure and color- 

 ation. It presents the two well-defined sulci on the somites with the 

 anterior of these taking its origin well below the pore and the three 

 longitudinal rows of flavous spots as in R. leucostigvia. The anal 

 valves are in most cases wholly ferruginous but may be in part dusky. 

 The anal scutum is bordered posteriorly by ferruginous, the extent of 

 this color varying. Perhaps the most important difference noted is 

 that in the Martinique form the anal tergite, while sometimes slightly 

 free at the tip, is in all cases much exceeded by the strongly protruding 

 anal valves, whereas in R. leucostigma, according to Pocock's state- 

 ment, the tergite is " produced into an acutely angular, blunt process, 

 which just surpasses the valves." Typically the collum is crossed 

 longitudinally at the level of the eye by a sulcus which in turn is 

 crossed by two vertical sulci as in R. liparus. Legs ferruginous. An- 

 tennae the same or brown. 



Number of segments up to forty-seven. 



Length up to 45 mm. ; diameter to 5 mm.
