joints of about equal size, terminal part about as long as those two joints com- 

 bined. Posterior antennae with the outer ramus very small, uniarticulate, carrying 

 2 short setae on the tip. Oral parts about as in L. tenuicornis. 1st pair of legs 

 resembling in structure those in L. attenuata, the inner ramus being composed 

 of only 2 joints, apical claw and seta comparatively slender. The 3 succeeding 

 pairs of legs likewise of a structure very similar to that in the said species ; inner 

 ramus of 4th pair however composed of only 2 joints, like that of the 2 preceding 

 pairs. Last pair of legs with the distal joint wholly confluent with the proximal 

 one, each leg forming an undivided small lamella of somewhat irregular form, 

 exhibiting in the middle of the posterior edge a slight incision, whereby 2 short 

 lobules may be distinguished, the outer one carrying 5 thin bristles, the inner 4 

 spiniform setae. Ovisac comparatively small, with a very limited number of ova. 



Male rather smaller than female and having the anterior antennae hinged 

 in the usual manner. Last pair of legs resembling in shape those in female, but 

 having a smaller number of marginal setae, which also are more spiniform in 

 appearance. 



Colour not yet ascertained. 



Length of adult female 0.68 mm. 



Remarks. This form also distinguishes itself by a peculiarity not found 

 in any of the other species, viz, the complete fusion of the 2 joints of the last 

 pair of legs. In all other structural details, however, it shows a close affinity to 

 them, and accordingly cannot be generically removed. The specific name here pro- 

 posed refers to the above-mentioned anomalous character. 



Occurrence. Only 2 or 3 specimens of this form have hitherto come 

 under my notice. They were found in the same samples from which the 2 pre- 

 ceding species were derived. 



Gen. PhyllOCamptUS, Scott, 1899. 



Generic Characters. Body sub-cylindrical in form, with rather thin integu- 

 ments. Rostral projection very small. Genital segment in female imperfectly sub- 

 divided. Caudal rami short. Anterior antennae less slender than in the preceding 

 genus. Posterior antennae likewise more strongly built, with the outer ramus 

 broader, though composed of only a single joint. Mandibles moderately strong, 

 palp comparatively small, biarticulate. Maxillae and maxillipeds nearly as in the 

 preceding genus. 1st pair of legs unusually short and stout, with the outer ramus 

 nearly as long as the inner, the latter biarticulate. The 3 succeeding pairs of
