white hairs ; punctations inconspicuous. Venter : very finely striate, 

 without punctations, but with numerous short, white hairs; vulva 

 facing the second intercoxal space. Anal grooves semicircular in front, 

 with sides reaching the posterior border and approaching each other 

 somewhat midway. Spiracles large, transversely oval. Capitulum: 

 (08 mm. I.) base twice as broad as long, with parallel sides and straight 

 posterior border ; destitute of cornua ; porose areas pear-shaped, trans- 

 verse, the broader end internal, interval less than their narrower 

 diameter, well-marked blunt auriculae, visible dorsally. Palps of 

 medium length, broad, outer border straight, inner border roughly 

 parallel with it but with an indentation at the junction of articles 2 

 and 3. Article 2 longer than article 8. Hypostome long, very slightly 

 spatulate, with large corona behind which there is a broad unarmed 

 median area ; dentition 4 1 4 in front to 2 1 2 behind, the outermost 

 teeth (10 per file) much the strongest 1 ; this and the next row extend 

 nearly the whole length of the hypostome ; the two internal rows short 

 and progressively smaller. Legs medium, coxa I bidentate, the inner 

 spur broad and curved ; trochanter I without dorsal projection but 

 with very slight ventral spur; coxae II-IV trenchant and with slight 

 postero-external spur; trochanters 2 and 3 slightly spurred ventrally 

 at their distal extremities. Tarsi fairly long, tapering abruptly ; claws 

 and pads small. 



Nymph : resembles the $ , but for the absence of the vulva and 

 porose areas, and the smaller spiracle (Fig. 214).

 Same origin as preceding. (Original, G. H. F. N. del.) 



1 Neumann (1902, p. 119) gives the dentition of I. praecoxalis as 4 | 4, that of 7. 

 intermedins as 2 | 2.
