SOME NEW AND LITTLE-KNOWN EXOTIC THYSANOPTERA 539 



sharply angled, broadly rounded below the eyes, and the head 

 ventrally emarginate as shown (pi. xiv., fig. 25). The eyes, set 

 laterally, are very small and finely facetted, occupying about 

 one-eighth the length of the head ; the ocelli are situated on a 

 hump near to the insertion of the antennae, directly above 

 the eyes, and are protected by the long, slender, white bristles. 

 Post-ocular bristles obsolete. The antennae are black with the 

 exception of the stem of the third and the apex of the second 

 joint, these possessing a reddish brown tinge. Joints two to six 

 claviform; fourth less than seven-eighths of third; third seven- 

 eighths of fourth ; sixth mutilated, and the apical joints un- 

 fortunately absent. Apparently a pair of sense-cones on each 

 of the joints three to five, and probably on the sixth. Viewed 

 dorsally the head is much narrower than in D. ampliceps 

 Bagnall, the dorsal surface looking like a strongly chitinized 

 carina; the cheeks are slightly swollen and set with a few 

 white setas. The colour of head is a very dark brown, almost 

 black ; there is a pale lateral patch behind eyes, and a similar, 

 though longer and narrower patch, reaching from base for 

 one-half the length of head on each side of the dorsal margin. 

 The dorsal margin is lighter in colour than the cheeks, whilst 

 above the cheeks we notice some light crimson hypodermal 

 pigmentation. 



The prothorax is apparently very short, and set with long 

 bristles as in D. ampliceps, Pterothorax mutilated ; wings 

 present, reaching to the ninth dorsal segment, coriaceous, with 

 yellowish tinge ; cilia greyish brown. Legs moderately long ; 

 fore-femur slightly thickened; fore-tarsal tooth minute; inter- 

 mediate and hind legs long. 



Abdomen broader than the pterothorax ; spines pale, long 

 and slender ; general colour very dark brown, lateral margins 

 with series of crimson patches. All tarsi yellow; tibias also 

 yellow, and shaded with brown below knees. 



Type. — In the Leyden Museum. 



Habitat. — A single specimen from Mount Kogui, New 

 Caledonia (A. Fauvel).
