herein may have been due to the difficulty in working with an 
imperfect specimen. When more is known about the Moluccan 
insect, the present variety may finally have to be merged with 
the species. As the case now stands, however, there appear to 
be sufficient differences from Crawford’s description to justify 
the tentative placing of the Philippine material before me in a 
separate variety. 
In erecting the genus, Crawford (’19: 147) made some re- 
marks regarding its being an anomalous one on account of its 
possessing some of the characters of both Pauropsylline and 
Triozinze. Supplementary to the characters he enumerated may 
be mentioned the caudally produced genital segment, which in 
combination with the reduced hind wings and other peculiar- 
ities point to a close affinity with certain members of Triozine, 
particularly Trioza diptera Crawford (719: 191, pl. 3, figs. 6 
and 7). 
Genus PAUROCEPHALA Crawford 
Paurocephala kleinhofie sp. nov. Plate 1, fig. 2; Plate 3, fig. 21; 
Plate 4, fig. 37; Plate 5, fig. 47. 
Male.—Length of body, 0.88 to 0.96 millimeters; width of 
head, 0.46 to 0.48; length of antennz, 0.26 to 0.31; length of 
forewings, 1.04, width, 0.48 to 0.52. Brownish yellow. Dark 
brown as follows: Apical and distal half of subapical segments 
of antennz; eyes; median suture of vertex; junction of radial, 
medial, and cubital branches with marginal veins of forewings; 
a spot on anal vein midway between proximal and distal ends 
of clavus; pleura and cox (unevenly so) ; anterior, posterior, 
and lateral margins of abdominal tergites and lateral three- 
sevenths on each side of abdominal sternites, except genital 
segment, anal valve, and genital forceps. Light stramineous: 
A narrow, sublinear band bordering each side of median suture 
of vertex; laterocephalic tubercle of pronotum; a narrowly sub- 
triangular, median spot from caudal to near cephalic margin of 
pronotum and another at mesoprescutum; posterior margin of 
latter; four faintly visible, longitudinal, narrowly linear mark- 
ings on median third, and a diffusely subcircular area adjoining 
laterocephalic margin of mesoscutum; lateral third on each side 
of mesoscutellum near bases of axillary cords; median prom- 
inences of pseudometanotum and fourth to seventh abdominal
