10 Psyche [Februarj' 



base of prothorax, sides nearly straight and parallel. Legs moderately stout; fore 

 femur nearly as long as head and about twice as long as greatest width; fore tibia 

 stout, scarcely as long as width of femur, with a stout, prominent tooth on inner side 

 of apex, just basal to which is a setose tubercle; fore tarsus with a long, strong, 

 hooked tooth about two-thirds its length, the inner surface of tooth with a setose 

 tubercle at apical two-fifths. Wings long, slender, weak, slightly suffused with 

 yellowish (particularly toward base), without double subapical fringe. 



Abdomen slender, slightly wider than pterothorax. Tube nearly O.G as long as 

 head, basal fourth slightly swollen, nearly 2.5 times as wide as apex; terminal bristles 

 brown, about 1.5 times as long as tube; all other abdominal bristles pale, in great 

 part knobbed. 



Measurements of holotype (female): Length 1.81 mm.; head, length 0.252 mm., 

 width 0.186 mm.; prothorax, length 0.205 mm., width (inclusive of coxae) 0.300 mm.; 

 pterothorax, width 0.288 mm.; abdomen, width 0.307 mm.; tube, length 0.144 mm., 

 width at base 0.074 mm., at apex 0.030 mm. 



Antennal segments: 1 



Length (/x) 39 



Width (ai) 40 



Total length, 0.373 mm. 



Described from a unique female collected by Lieut. A. W. 

 Jobb'ns-Pomeroy, on grass, near Ossidinge, Kamerun, in October, 

 1915. 



Genus Pselaphothrips no^-. 

 {\pri\a<j>aco, to feeU; Gpii/', a wood worm.) 



Body not depressed. Head much less than twice as long as wide, and more than 

 twice as long as prothorax, compressed and subcarinate above; cheeks nearly parallel, 

 not at all swollen toward base, and with a few small spiniferous tubercles; vertex 

 sulcate and nearly overhanging in front of anterior ocellus. Eyes moderate in size, 

 finely and closely faceted, scarcely prominent or protruding, well separated anter- 

 iorly, slightly reniform, exhibiting little tendencj- to surround the ocelli. Ocelli 

 anterior, not set on an elevation, the median one directed nearly forward, the pos- 

 terior pair approximate. Antennae eight-segmented, nearly twice as long as head, 

 scarcely "set on ventral surface of head," moderately slender, intermediate seg- 

 ments stout (that is, for the group; in the genotype scarcely three times as long as 

 wide), clavate, distally abruptly narrowed; sense cones long and slender. Mouth 

 cone very long and slender, attaining base of mesosternum. Prothorax broadly 

 arcuate (scarcely emarginate) in front, its median dorsal length more than one-third 

 the width across coxae. Legs moderately slender; fore femora not swollen, with an 

 acute tooth on inner surface near apex; fore tarsi armed. Wings slender, of equal 

 width throughout; fore pair with a subbasal dark band and many accessory hairs on 

 posterior margin. 



Type: Pselaphothrips pomeroyi sp. nov. 



1 In reference to the apparently very sensitive antennic, — althougli the function of the conidia 

 is presumably olfactory instead of tactile.
