be opposed to the tarsus as one's tliumb is opposed to one's fingers. 

 The tip of the tibia is enlarged, and the jumping, I think, is done in 

 the effort in bringing the tibial spur and the tarsus together. At all 

 events, there is no other modification of leg structure which would 

 seem to account for the superior jumping powers of the members of 

 this group." 



Dacttlopius poRMicAuiua, n. sjj. 



? adult viviparous, very short ovate, convex above, and flat beneath. Colour 

 whitish, thoracic and abdominal area with several distinct, narrow, transverse' 

 yellow-browu bars, which are confluent in the middle, forming a strong median 

 line. Antennae (fig. 2) of 8 joints, the width of the first almost equal to the length 

 of the last, formula 8 (1, 2) (6, 7), 3 (4, 5). Derm thickly set with short stiff hairs, 

 forming tufts at the margin of each segment; there are also numerous circular 

 spinnerets, and near the anal opening two large eye-like glands. Legs short, and 

 very stout, equal in length to the antennas, tibio-tarsal joint central or nearly so. 

 Anal ring of six long hairs. Anal lobes abnormally large, placed closely together, 

 and thickly set with long stiff hairs and spines. Long., 2 — 3 mm. 



Larva elongate. Anal lobes very faintly indicated, and furnished with very 

 long hairs. Antennae of 6 joints, formula 6, 1 (2, 3, 4, 5). Legs very long ; tarsi 

 longer than the tibise ; digitules to claw and tarsi simple.

Several specimens were collected by Mr. B. Tomlin at Courmayeur 

 Italy, circa 4000 ft. alt. Sept., 1899, in ants' nests (sp. non det.). 



In my description of this species (/. c.) I described the adult ? 

 as possessing antennse of six or seven joints. In the examples before 

 me I find a female possessing both characters. Mr. Tomlin says the 

 ants struggled to carry the Coccids away into their burrows. 



KiPERSiA Wasmanni, n. sp. 



? adult sub-ovate, rather flat, with the cephalic extremity slightly produced, 

 colour red. Legs well developed, anterior pair extending beyond 

 margin of the body. Antennae (fig. 3) a. little longer than the 

 tibia and tarsus together, of six joints, the articulation of 3rd and 

 4th faint, and not constricted at the margin. Mentum biarticulate, 

 and rather long ; loop of rostral filaments extending a little beyond 

 its apex. Anal ring with six stout hairs. Anal lobes indicated 

 by single long hairs, which are placed well within the margin. 



Long., 1 mm.
