No. 646. 
Stage II. (?)—Greatest length, 17 mm.; width at base of anal 
segment, 4-25 mm.; length in natural curved position, 7 mm.; thickness, 
3-75 mm.: width of head, 2-25 mm.; length to apex of labrum, 2-10 mm. 
White, the body showing bluish toward apex. Epicranial sclerite 
without sete. First antennal joint distinctly shorter than second, the 
antenne naked except for a single seta near base of second joint ventrad. 
Median channel at apex of abdomen ventréd,; longer than usual and with 
a row of about six scattered setzw on either side, close together, each 
row at apex caudad with an oblique row of denser set, about nine in 
either row, the lines of sete thus forming a Y with the blade double, 
thus Wie setee surrounding this Y rather seattered. 
No. 587. 
Stage I1/.—Greatest length at stretch, 26 mm.; width at base of. 
anal segment, 6 mm.,; length in natural curved position, 12 mm.; thick- - 
ness, 5mm.; width of head, 3-75 mm.; length to apex of labrum, 3-5 inn. 
Closely related to No. 650 but can be distinguished as follows :— 
Cephalic margin of epicranial sclerite with a row of rather dense set, 
behind this with a row of scattered sete (in No. 650 cephalic margin 
with one seta on either side of meson, the row caudad consisting of two 
sete on either side); first antennal joint much shorter than second; 
pubescence on thorax dorsad rather denser, anal path not so rounded 
eephalad, more V-shaped, its lateral margins not converging somewhat 
ceaudad, distinctly longer than its greatest width, with about twenty- 
four delimiting sete altogether, the sete not very closely set together 
(in No. 650, lateral margins of anal path somewhat converging caudad, 
no longer or not as long as its greatest width, with about thirty 
delimiting sete); scattered sete outside this path, dense, continuing 
arp the segment cephalad for distinctly more than length of anal path 
Gn No. 650 seattered sete not at all dense, only about seven on either 
side of meson cephalad of the path, and continued cephalad for distinctly 
jess than length of path) ; of a large and more slender build. 
Stage JI.—Greatest length, 16 mm.; width, 4 mm.; length in curved 
position, 7-5 mm.; thickness, 3-75 mm.; width of head, 2-5 mm.; length to 
apex of labrum, 2.25 mm. 
No. 671. ; 
Stage I11.—Greatest length at stretch, 28 mm.; width at base of 
anal segment, 6-5 mm.; length in natural curved position, 13 mm.; 
thickness, 5 mm.; width of head, 3-50 mm.; length to apex of labrum, 
3-00 mm. 
Very similar to No. 587 but first antennal joint not so short, 
delimiting sete of anal path denser and longer as in No. 650 and 
forming a broad horseshoe, wider than long, the sete nearly meeting 
caudad; scattered sete on venter of apex not so dense; body of a uniform 
opaque milky white. Will differ from No. 650 in its white colour, its 
Jonger and slenderer form, in bearing a row of setx along cephalic 
margin of epicranial sclerite, the setae on venter of apex denser and the 
sete of anal path closer together caudad. 
The characters given for these closely related species, namely, Nos. 
650, 587 and 671, appear constant, several specimens or more of each 
species having been examined.
