1920] Mann: Ant Guests 65 



Host: Iridoniyrmex sororis Mann. 



Described from two males taken with the host ant, in a 

 Myrmecocdia bulb. 



The elongate, slender antennae, the regular punctation and 

 the dark color are characteristic of cribratus. 



Fustiger levuanus sp. nov. 



(Fig. 2, c; Fig. 5.) 



Male: Length 1.25 mm. 



Reddish brown. Head, prothorax and elytra with rather stiff, sub- 

 erect hairs; abdominal fasiculse very small. Head less than twice as 

 long as broad, widest behind eyes, coarsely, foveolately punctate. 

 Antennas about as long as head, second joint clavate, compressed at 

 tips, uniformly punctate. Prothorax broader than long, broadest behind 

 eyes, sides convex, surface foveolately punctate. Elytra a little broadest 

 behind, sides convex, posterior corners rounded, surface with rather 

 strong and regular foveolate punctures which become finer on apical 

 third. Basal pit of abdomen not deep; barely one-third as long as abdo- 

 men; the surface posterior to the pit very strongly convex. Femora 

 incrassate, the spines about half as long as tibiae, stout basally and 

 strongly curved. Disc of metasternum impressed, first gastric segment 

 barely as long as second and third together. 



Koro Vatu, Viti Levu, Fiji. 



Host: Prenolepis bengalensis. Forel. 



Nadarimanu gen. nov. 



Note. — Near Fustiger, but differing in the structure of the abdomen, 

 which is very strongly margined for its entire length and instead of a 

 fasiculate inflation at the anterior end has a second, rounded margin 

 which bears an elongate brush of hairs. Abdominal pit very broad, the 

 posterior face flat and sloping and the non-excavated posterior part of 

 the first segment reduced to a convex ridge. Type alewa. 



Nadarimanu alewa sp. nov. 



(Fig. 6*) 



Female: Length 1.75 mm. 



Reddish brown. Hairs rather coarse, curved, semirecumbent, 

 abundant on head, body and appendages. Head, prothorax and elytra 

 with strong, foveolate punctures which are largest and more shallow 

 on the elytra. Abdomen very finely and sparsely punctate. Head about 

 twice as long as broad, as broad at anterior border as behind eyes, not 

 impressed above. Antennas much longer than head, the third joint 

 rather narrowly clavate and compressed. Prothorax a little longer than 

 broad, narrowed in front, sides convex at anterior half, nearly straight 

 behind; surface feebly depressed at base. Elytra together broader than 



* The antennae are more sinuate than shown in the figure.
