L.ELAPS SIMPLES, sp. nov. (PL 20. fig. 5.) 
Female. Long oval, shoulders not well marked. Dorsal plate straight- 
sided, reaching end of body, with three double rows of weak hairs, two on the 
posterior margin much longer. Epidermis distinctly striated. Sternum of 
rather uniform breadth, reaching to middle of third coxse ; front margin 
undulate, with slight lateral extensions ; posterior corners pointed ; end margin 
with a small notch at the middle; the three pairs of hairs are placed close to 
the margin of the shield. Genital plate exceptionally long (length 110 /a) 
and narrow, being more than twice as long as broad, reaching well beyond 
the last pair of coxae, only slightly widened at the extremity, which is some- 
what rounded. Ventro-anal plate small (length 90 /a, breadth 95 /x), widely 
removed from genital plate and placed on the end margin of the body, evenly 
rounded in front and truncated behind. A pair of small inguinal plates lie 
near the side margins. The inner pedal plates lie between the last pair of 
coxae, which are partly enclosed by a chitinous extension of the peritreme. 
Chelicerffi small, though of robust structure. Legs and palps stout and of 
moderate length ; inner side of second palp segment with one, and third 
segment with two stout spines. Length 450 /x, breadth 260 yu..

hairs present, but the plates are indistinct. Genital plate large (length about 
150 /x along middle line), elongate, constricted at the middle; front margin 
produced and elaborately fimbriate, hind margin straight ; anterior part of

posterior margin of body; surface with transverse lines; front margin much 
wider than genital plate. The outline of the plate of an earlier nymphal form 
is indicated in the drawing. Peritreme v.'ith a slight regular curve; there is 
no protecting plate, and a weakly-chitinized post-stigmatic process encloses the 
last pair of coxae. Maxillary plate quadrate, corniculi narrow and placed 
close together. Legs long and slender (length of first pair 450 //., of fourth
