to side, tlie fonner dimension measured laterally, the latter 

 I'rom above. 



The tibia measures "22 mm. long and -13 mm. broad. At 

 its di.-tal end on the outer side it bears a subtriangular, 

 pointed, semitransparont apophysis projecting oblicjui'l}' tor- 

 wards and outwards, and measuring '045 mm. as seen tVom 

 above. 



The palpal organs are rounded and convex. They show a 

 small hook-like process between the middle and the apex, the 

 tip of the hook being directed inwards. On the inner side 

 near the apex is a corneous process, ending in a sharp i)oint 

 projecting forwards and outwards. A little white glistening 

 membrane occupies the extreme apex of the palpal organs. 



Leys. — Coxtc and trochanters yellow-brown witli dark 

 brown markings. Femora dark brown, with the exception of 

 the basal halves of the four anterior ones, which are yellow- 

 brown. 



Femora i. and ii. each bear two spines above, one near the 

 base and one near apex at the inner side. 



Femur iii. also bears two spines, one on the distal and the 

 other on the proximal third. 



Femur iv. only shows the proximal spine. 

 All the remaining articles are dark brown. 

 TibiaB and metararsi i. and ii. clothed beneath with long 

 hairs and bearing no long spines. 



Ti 1)183 and metatarsi iii. and iv. each bear several pairs of 

 long spines below ; these are more or less concealed among 

 the long hairs clothing the part, and are difficult to count. 



Tarsi all scopulate, the four anteriors much more thickly 

 so than the four posteriors. 



Abdomen dark brown, almost black, sparsely covered with 

 scattered, thick, iridescent hairs which do not form a pattern. 

 There are faint indication.-; of a pair of yellow-brown spots on 

 the anterior third, tbllowed by several chevron markings. 



Spinners. — Upper spinners yellow-brown, lower spinners 

 almost black. 



The following is the analysis of Mr. Elton's total catch : — 



Adult specimens 43 



Immature (probably L. sobria) 16 



Immature and unrecognizable 33 



Total 92 



There was no indication that any of the immature specimens 

 belonged to any species not included in the above list, but, of 

 course, it is q^uite impossible to be sure.
