telopodites proportionately small, curving forward from between 

 the coxae as slender, unsegmented and unbranched blades subparallel 

 to each other throughout.

 4,642. Fijis: Nadarivatu, Waigonibu, Vanua Ava, Lomati, 

 Lasema (W. M. Mann). 



General color of males as in Phlyctodesmus ynyrmecophor, the somites above 

 and laterally chestnut excepting the first tergite which is flavous. Legs 

 flavous. Antennae brown. The females are a duller, less reddish brown. 



Granulation of head much reduced, the granules exceedingly fine or obscure 

 so that the surface appears smooth, densely clothed with short stiff hairs. 

 The vertigial sulcus extending across vertex but not at all down the front. 



Surface of first tergite like that of head but hairs much shorter and finer, 

 appearing like bloom on fruit. Other tergites similarly with granules very 

 fine and hairs of same character but in addition with transverse series of 

 larger though still small granules each of which bears a stouter and longer 

 distally finely pointed seta. Lateral swelhngs of metazonites more pro- 

 nounced, bulging more over the pleural region. Second tergite extending 

 forward on each side as in Phlyctodesmus. Pores opening through short 

 cyhndrical elevations like the mouth of a gunbarrel, the rim appearing finely 

 fringed. Anal tergite in profile with dorsal line strongly convex, the cauda 

 much exceeding the valves, decurved. 



Length (female), up to 13 mm., the males smaller. 



Solomonosoma, gen. nov. 



Composed of head and twenty somites. Having general form of 

 Orthomorpha. Keels reduced but distinct and very thick, with the 

 second one much below level of the others. Antennae long and 

 slender. Sternites without processes excepting the plate on the fifth 

 in the male. Pleural keels on first to fourth segments, those of first 

 and second sub vertical and extending up to tergal keels. The usual 

 processes above bases of legs. Sulcus across tergites present but this 

 not sharply impressed and often obscure. Anal tergite broad, shovel- 

 formed, caudally subtruncate. First legs of male strongly thickened; 

 third joint at base below with a large process as in Antichiropus and 

 Somethus. Hairs on ventral surface of tarsus in male more numer-
