300 FAUNA HAUAIIENSIS 



Fam. ENTOMOBRYIDAE. 



Lepidocvrtus Bourlet. 



This is a large and widespread genus, many species of which have been described 

 from various regions. The discrimination of the species is difficult on account of the 

 slight, comparative characters on which most of them are founded. 



(i) Lcpidocyrtiis hcterophthalimts, sp. nov. (PI. IX. figs, i- — 6). 



Length 2 mm. Antennae slightly longer than the head ; relative length of 

 segments as 3 : 5 : 3 : 7 (fig. i ). Eight ocelli on each side, two proximal much smaller 

 than, and behind the other six (fig. 2). Thora.x markedly overhanging head. Feet 

 without tenent hairs ; each upper claw with two small but distinct teeth ; lower claws 

 elongate and untoothed, those on fore-feet less elongate than those on middle and 

 hind-feet (figs 3, 4). Fourth abdominal segment four times as long as third. Dens 

 as long as manubrium ; mucro elongate with the usual apical tooth, a prominent ante- 

 apical tooth and a rather stout basal tooth (fig. 5). Colour of dried specimens silvery- 

 white with metallic reflections. Scales very variable in form, but all markedly longer 

 than broad (fig. 6). 



The absence of tenent hairs on the feet, together with the size and arrangement 

 of the ocelli, distinguish this species from all the Lepidocyrti known to me. Its nearest 

 ally seems to be Z. ralumensis, .Schaffer ', from Ralum, in the Bismarck Archipelago, 

 which has short tenent hairs on the feet, and the two proximal ocelli much smaller than 

 the other six, but not so distinctly posterior in position as in this Hawaiian insect. 



Hab. Hawaii : Kona, 2000 ft, Perkins, Sept. 1892 ; Mauna Loa, 4000 ft. 



Entomobrya Rondani. 



Degeeria Nicolet, Nouv. Mem. Soc. Helvet. Sci. Nat. 1842 (nom. praeocc). 

 Sinella Brooke, Journ. Linn. Soc. (Zool.) 1882. 



This is another cosmopolitan genus in which many species have been described, 

 largely on account of differences in colour and markings. Two very distinct forms — one 

 from Hawaii and the other from Kauai — are present in the Sandwich Islands. They 

 may be readily recognised thus : 



(a) Colour yellow with lateral purple stripes ; feet with tenent hairs ; mucro with 



basal tooth insularis. 



(d) Colour yellow with complex purple markings ; feet without tenent hairs ; mucro 



with no basal tooth kalakaua.
