6 14 FAUNA HAWAIIENSIS 



(4) Scleroderma sophorae, sp. nov. 



Head and thorax brown, rarely altogether concolorous, the prothorax usually being 

 distinctly paler (more yellowish) than the sordid parts behind it, the head too (except 

 anteriorly) is more often concolorous with the paler pronotum, than with the mesonotum 

 and propodeum. Antennae entirely pale, the funicle joints with fuscous rings. All the 

 legs are yellowish-tinged, but they are for the most part of a dark colour, brownish or 

 sordid, with yellow tarsi. The basal segment and tip of the abdomen are brown or 

 yellowish brown, the intermediate segments black or dark brown, with the apices some- 

 what widely pallid. When the intermediate segments are paler than usual, the basal 

 segment is always paler still (more yellowish). 



Head very long and narrow, parallel-sided, the eyes only about one-third as long 

 as the distance from their upper margin to the occiput ; the surface appears smooth, 

 the minute reticulation, distinct enough under high powers of the compound microscope, 

 being invisible under a very strong lens ; on the thorax, however, the reticulation can 

 be distinguished with the latter, appearing as an excessively fine puncturation or 

 shagreening. The antennae are short, the funicle joints for the most part strongly 

 transverse, the pedicel as long as the two next joints together. Abdomen more shining 

 than the thorax, and as long or a little longer than the latter and the head together. 

 Length, ? 2*5 mm. 



Hab. Hawaii, 4000 ft. ; bred from the dead wood of Sophora. 



Obs. It is clear to me from the examination of this species and from others, of 

 which I have seen a number of examples obtained in company, that slight differences 

 of colour are not of specific value in this genus. Further, the abdominal segments are 

 subject to retraction and I suspect that Ashmead's S. breviventre is an unnaturally con- 

 tracted specimen. 



SiEROLA Cameron, 

 (i) Sierola dichroma, sp. nov. 



Female black, the lower part of the face, the head about the posterior angles, the 

 pronotum and mesonotum ferruginous, legs, scape of antennae and mandibles paler, 

 yellow testaceous or whitish, rest of antennae infuscate or sordid, abdomen brown-black, 

 paler in parts. 



Male ferruginous, a dark cloud about the ocelli, a black transverse one along the 

 scutellar and propodeal suture, the base and about five transverse indefinite fasciae on 

 the abdomen dark, mandibles whitish, legs pale yellow, base of antennae clear yellow, 

 the rest more sordid or brownish. 



Head in both sexes very broad, the temples rounded, the surface dull and cori- 

 aceous and with distinct, remote, shallow punctures. Antennae moderately long, the
