COLLEMBOLA 301 



(1) Entoniobrva uisiilaris, sp. nov. (PI. IX. figs. 7 — 11). 



Length 2 mm. Antennae 27 times as. long as head ; relative length of segments 

 as 6 : I I : 9 : 10 (fig. 7). Eight ocelli on each side, arranged as usual in an outer 

 sinuous and an inner even row, the hindmost ocellus of the latter much smaller than the 

 rest (fig. 8). Legs slender and very long Feet with very prominent tenent hairs; 

 upper claws straight with two prominent teeth ; lower claws untoothed, parallel-sided in 

 fore-foot, more tapering on middle and hind-feet (figs. 9, 10). Fourth abdominal 

 segment five times as long as the third. Dens nearly as long as manubrium ; mucro 

 stout, with straight ventral edge, blunt apical tooth, prominent ante-apical tooth and 

 slender basal tooth (fig. 11). Colour pale chrome yellow with purple markings, viz. — 

 paired narrow lateral stripes on head, marginal stripes on mesothora.x, angular marks 

 on metathorax, and lateral stripes from front of abdomen to the middle of the fourth 

 segment. Body and legs with numerous plumose hairs. 



Structurall)-, this species seems to come nearest to the widespread E. viarginata 

 Tullb. (see Schaffer, loc. cit. supra), but the dark bands on the hinder edge of each 

 abdominal segment, which characterise even the pale varieties of that insect, are quite 

 wanting in the present form, which is moreover of larger size and possesses more robust 

 foot-claws and mucrones than the European species known to me. 



Hab. Hawaii: Mauna Loa, 4000 ft., August, 1892, two specimens; Kona, 

 2000 ft., Perkins, Sept. 1892, several specimens. 



(2) Entoiuohrya ka/akaiia, sp. nov. (PI. IX. figs. 12 — 16). 



Length 2'3 mm. Antennae (last segment missing) about half as long as head and 

 trunk ; relative length of segments as 5 : 10 : 9 : ? (fig. 12). Eight ocelli on each side, 

 three large and a smaller hind one arranged in the outer slightly sinuous row, and four 

 in an inner straight row, the front one small, the next smaller, and the two hinder widely 

 separated and very small (fig. 13). Feet without tenent hairs, upper claws strong and 

 slightly curved, each with two prominent teeth ; lower claws small, untoothed and 

 tapering (figs. 14, 15). Fourth abdominal segment four times as long as third. Dens 

 slightly longer than manubrium ; mucro with prominent ante-apical and apical teeth, 

 but without basal tooth (fig. 16). Colour bright chrome-yellow with complex purple 

 markings consisting of lateral stripes on the head, broad lateral stripes and central 

 patches on the mesothorax and metathorax, broad transverse bands with sinuous front- 

 margins on the hinder edge of the second and third abdominal segments ; on the fourth 

 abdominal segment four lateral stripes, the two outer of which have an irregular, zigzag 

 form, and unite centrally and anteriorly; on the fifth abdominal segment an apical patch. 

 First antennal segment light purple, second and third dark violet. 



The presence of sixteen ocelli and the absence of tenent hairs on the feet render 

 this species an interesting link between typical Entomobryae (with sixteen ocelli and
