A NEW GENUS OF TERMITE GUEST FEOM FIJI. 

 By Wm. ]VI. Mann, 



Bureau of Entomology, Washington, D. C. 



The beetle described below, was collected by the writer on several 

 different islands in Fiji, where individuals occur, one or two to a 

 colony, with a termite (Nasutitermes sp.) common throughout the 

 group and found in dead wood. They were running among the host 

 where the latter were gathered thickest, in a manner common to 

 many species of termitophiles, and similar in habits and behavior 

 to our southern species, Trichopsenius depressus Lee.

 Head, small, not constricted at base, broader than long, sides and 

 occiput convex, vertex flattened. Eyes occupying less than half 

 sides of head, glabrous. Antennae inserted in rather large and 

 shallow foveae near interior margin of eye; 11-jointed; first joint 

 three times as long as the third, remaining joints sub-equal in 

 length; joints 3-7 cylindrical, 8-11 com.pressed, the apical more 

 strongly so than the others. Clypeus submembranous, anterior 

 margin straight. Gula subcampanulate. Labrum twice as long 

 as broad, the anterior border strongly, broadly and triangularly 

 excised at the middle. Mandibles acute at the apex. Submentum 

 and mentum not distinctly divided, together large and sub-quad- 

 rangular, with the outer angles rounded. Ligula small, strongly 

 excised apically ; paraglossse not visible. Labial palp thick basally ; 

 second joint half as broad as the basal ; apical joint less than half 

 as broad as the second. Maxillary palp 4- jointed, basal joint short, 

 second and third joints siibequal, the apical slender and much 

 shorter than the third. Pronotum broader than long and a little 

 broader behind than in front, sides strongly convex, anterior and 

 posterior angles evenly rounded and not at all projecting. Elytra 

 strongly transverse, nearly as broad and about two-thirds as long 

 as pronotum, sides inflexed as in pronotum. Metasternum broad,
