Total length of antenna, 0-351 mm. 

 Described from two females taken by sweeping in forest at Nelson, N.Q., April 

 28 and May 21, 1914, by Mr. A. A. Girault. 



iStructurally very close to Ph. pictus, but easily known by the obscurely 

 maculate prothorax and the dark postocular vitta. 



HELIOTHRIPS SCULPTILIS sp. nov. 



Female (macro pteroiis). — Length about 1 mm. Colour blackish brown, thorax 

 paler, head yellow in front of ocelli ; knees, tarsi, ends of tibiae, and basal half of 

 antennal segments 3-5, nearly white : fore wings light brown, with a narrow white 

 band bej'ond scale and one in eighth tenth, the apex pale. 



Head closely and finely reticulate, occiput with exceedingly fine rugae between 

 the lines of reticulation ; frontal costa nearly as wide as first antennal segment. 

 Eyes not protruding, about twice as long as their distance from posterior margin of 

 head. Ocelli equidistant. Antennae almost exactly as in H. pfiaseoli {sec Psyche, 

 vol. xix, 1912, PI. 8, fig. b). Maxillary palpi two-segmented. 



Prothorax reticulated and roughened like occiput. Mesoscutum paler than 

 other jjterothoracic plates, with sides and posterior portion closely striate, the remain- 

 der sculptured like occiput. Fore wings with veins and bri.stles as in H. fhasioli (I.e., 

 fig. «)• 



Abdomen of normal structure ; tergites 1-8 closely striate at sides, the striae 

 transverse toward middle of .segment and longitudinal at sides, as in H. phaseoU (I.e., 

 fig. c). Tergite 10 divided in apical half. 



Measurements of holotyjie : — Length 0-984 mm. : head, length 0-120 mm., 

 width 0-1 57 mm. ; prothorax, length 0-096 mm., width 0-178 nun. ; pterothorax, width 

 0-240 mm. ; fore wing, length 0-698 mm., width near base 0-075 mm., at middle 

 0048 mm. ; abdomen, width 0-294 mm.

Width (/i) 24 29 21 21 19 



Total length of antenna, 0-241 mm. 



Described from one female taken by " sweeping in an old Chinese garden, 

 overgrown partly with weeds," Proserpine, N.Q.. November 3, 1912, by Mr. A. A. 

 Girault. 



The striate abdomen and the colour of the wings are the most distinctive 

 characters. 



PTEROTHRIPS gen. nov. 



(nrepov, wing ; 6pnfi, a wood- worm.) 



Body deeply reticulate. Head large, subquadrangular, much broader than 

 long, strongly constricted at base ; vertex transverse, slightly elevated between eyes 

 but not surpassing them anteriorly. Ocelli approximate, elevated, the anterior
