414 SNODGRASS 



S. melanocera immaculata (PI. xxvii, fig. 6). — Resembles the 

 Iguana Cove form in the possession of a light abdominal stripe, but 

 differs from S. m. lineata and fi^om all the other races in lacking the 

 yellow spot on the side of the prozona. Since Scudder had two 

 specimens which he says sh6w a very faint trace of the prozonal 

 spot, it is probable that some may be found having it well developed. 

 Its absence, however, is so conspicuous that the race is a very strongly 

 marked one. 



From Indefatigable Island. 



The species inhabits also Jervis, James and Narboro Islands, but 

 the material at hand from these islands is insufficient to determine 

 the status of the species on them. The few Narboro specimens 

 show affinities to both the Tagus Cove and the Iguana Cove races on 

 Albemarle. 



S. literosa discoldalis (PI. xxvii, fig. 4). — Smaller than any of the 

 jfielanocera varieties, of a paler general coloration, lacking strongly 

 contrasting black and yellow markings ; terminal half of tegmina 

 spotted with conspicuous large quadrate dusky blotches ; prozona but 

 slightly shorter than metazona. 

 From Chatham Island. 



This race may be taken as typical of S. literosa^ and it is probable 

 that the type of this species came from Chatham Island. 



S. literosa hyalina. — Conspicuously joaler than the Chatham form, 

 reticulations of tegmina lighter; tegminal spots smaller; prozonal 

 stripes less strongly marked ; prozona shorter than metazona. Eyes 

 slightly farther apart than in 6". /. discoidalls. 

 From Tower Island. 



The Chatham and Tower forms are of about the same size, each 

 being smaller than the Hood variety. 



6". literosa punctata. — Distinctly larger than either of the other 

 two literosa forms ; the prozona relatively shorter, less than four fifths 

 as long as the metazona ; tegminal reticulation as in the Chatham 

 form, tegminal maculations very distinct. 



S. intermedia intermedia (PI. xxvii, fig. 3). — Characters vary in 

 all degrees from those of typical 6*. melanocera inelanocera speci- 

 mens, to those of typical S. literosa punctata specimens. 

 From Duncan Island. 



S. intcrfnedia borealis (PI. xxvii, fig. 3). — Resembles in coloration 

 intermediate Duncan individuals ; color relatively uniform ; maculation 

 of tegmina well marked. 



From Abinsrdon and Bindloe Islands.
