628 FAUNA HAWAIIENSIS 



subquadrate, about as long as its greatest width, the apical joint ovate, just as long as 

 the two preceding together, but not quite twice as long as its greatest width. Head, 

 thorax and abdomen smooth and polished, the head sparsely pilose ; the pronotum, 

 propodeum and abdominal petiole with dense pale ochreous wool-like hair. Neck when 

 exposed coarsely transversely rugose. Scutellum distinct, not impressed at base, the 

 axillae not defined. Wings quite rudimentary, mere filaments, clothed like the propo- 

 deum and easily overlooked. Abdomen ovate, pointed at apex, the second segment 

 twice or more than twice the length of all the following together. 



Male closely resembles the female ; the antennae are longer, being as long as the 

 whole insect, the first and second flagellar joints elongate, the second being distinctly 

 longer than the pedicel, most of the following joints roundish and moniliform. 



Van a. Smaller, the scape and pedicel concolorous with the legs, the abdomen 

 brown, black only apically and at the sides, the head also less black. 



Hab. Oahu ; 1 500 — 2000 ft. 



(5) Phaenopi-ia montana, sp. nov. 



Black, the legs rufotestaceous, the antennae red, becoming darker apically so that 

 towards the tips they are black or almost so ; thorax sometimes dark brown or pitchy, 

 a little rufescent in front. 



Smooth and shining, the antennae formed much as in P. ambulator, the third joint 

 quite strongly elongate, decidedly longer than the pedicel. Posterior part of thorax 

 very densely covered with appressed yellowish hair, the abdomen with a rather con- 

 spicuous clothing of subdecumbent pubescence. When seen from in front it is notice- 

 able that these abdominal hairs are more or less directed towards the middle line from 

 each side. Lengfth 2 mm. Readilv disting-uished from P. ambulator bv colour and 

 abdominal vestiture. 



Hab. Honolulu mountains, about 2000 ft. 



(6) Phaenop7'ia hylaea, sp. nov. 



Closel)^ allied to P. ambulator. Head, thorax, two basal joints of the antennae 

 and the legs ferruginous or testaceous ; abdomen and the flagellum of the antennae 

 black. 



Head smooth, flattish above, and thinly clothed like the thorax and abdomen with 

 short erect hairs. Antennae much shorter than those of P. ambulator ; the pedicel is 

 rather wider and longer than the following joint, which is subelongate, the fourth and 

 following joints are small and nearly round, while those preceding the apical one are 

 strongly transverse, the latter conic-ovate and shorter than the two preceding together. 

 Thorax and abdomen smooth and shining, the hairy covering of the posterior part of 

 the former yellowish, and less dense than that oi P. ambulator. Length r5 mm.
