having the first branch of the median vein of the tegmina springing 

 from decidedly beyond the median point and in having the ventral 

 margins of the median femora unarmed. 



Type: 9 ; Obi Island, Moluccas. [Hebard Collection, Type 

 no. 809.] 



Size large for the genus, 45 form elongate. Vertex narrow, acum- 

 inate, produced distinctly beyond plane of face, sulcate from near 

 occiput to apex. Pronotum rugulose, polished and appearing 

 rather smooth to the naked eye; disk with cephalic margin broadly 

 convex but showing a trace of angulation, caudal margin broadly 

 convex, transverse sulci distinct, a medio-longitudinal carina feebly 

 indicated cephalad and caudad, obsolete elsewhere but supplanted 

 by a short deep sulcus before the principal sulcus; lateral lobes as 

 deep as long, ventral margin rounded obtuse-angulate. Tegmina 

 and wings very elongate; the former narrowing very gradually 

 distad, with rounded apex median in position, median vein with 

 first branch slightly before end of proximal three-fifths and with 

 two distal branches. Ovipositor elongate, slender, unarmed, 

 straight. Subgenital plate with length approximating width, 

 convex, margin bilobate distad with a small triangular median 

 emargination. Ventral femoral margins armed with small spines, 

 as follows. Cephalic internal 2 and 3, cephalic external 0, median 

 internal 0, median external 0, caudal internal 12 and 13, caudal 

 external 11 and 13. Femora with genicular lobes unispinose, 

 except the internal of the caudal femora which are bispinose. 

 Thickened portion of caudal femora with low convexities on its 

 dorsal surface. Cephalic tibiae with auditory foramina apert on 

 internal face, conchate on external face, dorsal surface sulcate and 

 entirely unarmed. 



General coloration clay color. Antennae very feebly suban- 

 nulate. Tegmina with flecks of warm sepia in areas between 

 median vein and its first branch and in areas between median, 

 mediastine and ulnar veins. Femora verona brown, heavily 

 flecked and marked with clay color, the caudal femora paling distad, 

 spines tipped with dark brown. Ventral surface of abdomen 

 rufous. Ovipositor cinnamon buff shading to chestnut distad. 



Length of body 52.5, length of pronotum 7.7, caudal width of 

 pronotum 5.8, length of pronotal lateral lobe 5, depth of pronotal 

 lateral lobe 5.1, length of tegmen 66.8, greatest width of tegmen 

 9.7, distal width of tegmen 6.7, length of cephalic femur 15.1, length 

 of caudal femur 37, length of ovipositor 30, greatest width of ovi- 

 positor beyond base 2.8 mm. 



The type is unique. 



Segestidea soror new species. Plate XVI, figures 3 and 4. 



We have compared this species with Segestes frater, here de- 



46 In fact largest of the genus, excepting S. decoratus Redtenbacher, which 

 hpecies may very possibly be referable to Segestidea.
