forward well over the head ; the lateral plumes are strong and of very plumose- 

 hnirs. 



The abdomen carries the usual plumes on the tirst two segments ; these are 

 of plumose hairs, the remaining long hairs (except the siphonal plumes) 

 are only subplumose ; on the sides and dorsum are a number of small stellate 

 hairs, but possibly owing to denudation, I fail to recognise any symmetrical 

 arrangement. The comb shows (dorsally) as 12-6 sharp scales, irregularly 

 distributed, the longest being in front. The siphonal plumes moderate, the 

 sub-siphonal fairly deyeloped, with plumose hairs. 



The siphon is considerably longer than the abdomen ; 12-13 units as 

 compared with 10 of the abdomen. The spines are few and run for less 

 than a quarter of the length of the siphon, which is 20 times as long as 

 its base. 



The anal segment is long, being twice the length of its base. The papillae 

 are about the same length as the segment, but some are a little longer ; on 

 the dorsal edge are four yery strong dark hairs and some of less length ; 

 the yentral beard is moderate but bushy, and runs for one-third of the 

 segment. 



The laryae are about 5 mm. in length, siphon o\ mm. ' 



Pupa. 

 This is characterised by yery long thin trumpets and a series of stellate 

 hairs on the dorsum of the abdomen (PI. VII, figs. 1, 2, 3). 

 Length of thorax 1^ mm. 

 Described from six laryse and fiye pupa?.

IjARyA. 



Very dark, Avith large head and antennae ; head highly chitinisod, quite 

 opaque. 



Antennae with a yery large plume of plumose hairs ; the lower part is 

 dark, but the part below the plume and the distal joint are much lighter in 

 colour ; it is much constricted at the root of the plume and the spines at the 

 end are long and dark (PL VII, fig. 8). Brush very prominent, and also- 

 the hairs on the maxilLT. Central plumes on the face moderate, but those 

 near the antennae are unusually thick, the hairs not being in the same plane 

 and being black in colour (PI. VII, fig. 9). 



Thorax differentiated, and with the usual plumes. 



Abdomen with the usual plumes on the first two segments, but symmetrical
