308. Orthomorpha lampra, sp. nov. 

 Type.— M. C. Z. 4,628. Fiji: Leviika (W. M. Mann). 



Metazonites above deep chocolate, the keels not paler, prozonites and sides 

 lighter; the venter and legs fulvous; antennae distally dark brown, paler 

 proximally. 



Dorsal surface not tuberculate or granular, shining, under lens appearing 

 finely and not strongly coriarious. 



Vertigial sulcus of head deep, reaching nearly to level of upper margin of 

 antennal sockets. Frontal and clypeal regions with numerous long stiff setae. 

 Face in profile angularly bent forward at lower level of antennal sockets. 



This species stands apart with 0. hisulcata Pocock from Burma in 

 having the tergites mostly crossed by sharply impressed median 

 longitudinal .sulci in addition to the transverse sulci; but in the present 

 species this longitudinal sulcus is distinct even on the first tergite 

 and all others to and including the nineteenth whereas it exists only 

 on segments from the third to the eighteenth in hisulcata. The keels 

 are very narrow but thick dorsoventrally, with pores toward low^r 

 margin of edge; posterior angles not produced in any. Last tergite 

 of usual form, notched caudally; crossed with a basal, submedian, 

 and subapical transverse series of setae. 



Other segments with a series of setae across anterior border of meta- 

 tergite. 



In the male gonopods both the coxae and telopodites very long. 

 The latter cla\ately widened distad from a narrow base; each on the 

 mesal side distad of middle with a branch in the form of a broad thin 

 plate with distal end concavely excavated and dorsoventral face 

 concave. The principal l^ranch is also thin and flattened and is 

 geniculate, bending abruptly mesad near its middle, its ventral 

 surface concaA-e. Opposite the mesal branch the seminiferous branch 

 arises, this bending obliquely across the main branch and extending 

 distomesad in contact with the mesal and ventral surface of the latter; 

 just above the origin of the seminiferous branch a curved, slender 

 and acute spur. 



Length, near 20 mm.; width, 1.8 mm.
