Wig. 19 A-K and 20 A-K. 
Redeseription of Adult. Fiy. 18 A-K, Shape as in ontline fig, 19A, hystero- 
soma ronghly oblong, wider anteriorly sevoss the rounded shoulders, posteriorly 
rounded ; propodosome somewhat triangular, basally mueh iarrower than anterior 
margin of hysterosoma info which it is slightly sunken and from whieh it is sepa- 
rated by » transverse posteriorly concave suleus. Colour entirely red but with a 
light whitish dusting, especially on the legs, dne to the setae. Length to 2-71 
mm., Width across shoulders to 1:46 mm. rista, Fig. 19R, elongate but mode- 
rately broad and tapering anteriorly, with subposterior sensillary area at about 
34 from apex, length to G00, sensillary bases 54 apart, sensillae ea. 200 lang, 
filamentous, apparently nude, Eyes 2+2, on well developed ocular shieds, pos- 
terior eyes the smaller, Legs all shorter than the body, 1 2175p, 17 1380p, IT 1350, 
TV 2250; tarsus T (Fig, 19 D) elongate oval to 450u long by 180p high — 2-5 
ratio, metetarsus I to 845. long, ratio length of tarsus to metatarsns = 1-3, Palpi, 
Fig. 19 C, stout, tibia with stout apical elaw and smaller stout aceessory elaw, two 
pectines, and on external side with 2-4 stont strong spines arising near base of 
palpal tarsus (Uirst says 2 to 3 spines, but the number is variable, even in the 
save specimen und sometimes one may be mure slender) ; tarsus elongate, hardly 
clavate and only very slightly execeding tip of tibial claw. 
Clothing dorsally on propodosoma mainly and on hysterosome entirely of two 
forms and sizes; the larger, Fig. 19 E-F, to 50u long, globose or subglobular, 
thistle-like with a distinet chamber marked off by a septum, apieally above the 
septim open and with a cistinet whorl of setnles, ofherwise evenly with long 
ciliations, arising from a voseite-like tubule; the smaller cup-shaped (Fig. 19 G). 
1820p lony, arisiiy from # rosette-like tubule, with five ciliations and in some 
views showing distinetly the Jateval margins of (he scale which is apparently eurled 
to form the cup (see Mig, 19 GQ) ; on the propodosoma. laterally above the anterior 
pairs of coxae are a nomber of small, 21p, ciliated, pointed setue (Fig. 19 TL), whieh 
dorsally appear fusifarm, but ventrally show distinctly a clear space and the
