Larva, Stage IV (plate 108, fig. 364). Head rounded, wider than long, 

 widest through eyes ; antennae long, rather slender, a large tuft at outer third, 

 part beyond slender; upper pair of dorsal head-hairs multiple, short. Body 

 with skin pilose on thorax, glabrous on abdomen; lateral hairs in threes after 

 second abdominal segment. Lateral comb of eighth segment of many spines in 

 a triangular patch. Air-tube about six times as long as wide, regularly tapering 

 outwardly ; pecten of rather long teeth, evenly, closely spaced and reaching basal 

 third; six hair-tufts beyond pecten, in line. Anal segment longer than wide, 

 ringed by the plate, which is spinose on its posterior third; dorsal tuft of two 

 long hairs and a short one on each side ; ventral bnish well developed, confined 

 to the barred area. Anal gills moderate, ensif orm, about as long as the segment, 

 upper pair slightly shorter than lower. 



- The larvae live in ground-pools. Mr. Urich obtained them in a small grassy 

 pool. 



Island of Trinidad, West Indies. 



Laventille (F. W. Urich). 



We are uncertain of the identity of the two males mentioned in the original 

 description as having been bred by Mr. Busck, and accordingly at present ex- 

 clude them from this species.
