83. Campylomma pallida , new species ( fig. 24 , b).

Oval, shining, uniformly clothed with a pale, subappressed pubescence.

Head much broader across eyes than long, 25: 18; the interocular space wider than an eye, 11: 7, male, 12: 6, female, vertex without conspicuous punctures. Tylus and juga only moderately convex. Rostrum relatively long, distinctly surpassing hind coxae, reaching about to apices of hind trochanters, proportion of segments 10: 12: 8: 12. Antennae about as long as head, pronotum, and scutellum, the second segment four fifths as long as head width including eyes in the male, three fourths as long as head width in the female; proportion of segments, male, 6: 20: 11: 7; female, 6: 18: 11: 7.

Pronotum one ninth shorter than head and slightly more than twice as broad across humeri as long, 33.5: 16, the disk quite smooth, without conspicuously raised callosities.

Hemelytra subhyaline, the clavus, corium, and cuneus covered with the same type of hairs as head, pronotum, and scutellum.

Color entirely pale testaceous to ochraceous with brown eyes, faintly clouded membrane, brown apex of rostrum, several stiff black bristles at apices of femora, stiff black bristles on tibiae, and femoral spots as follows: one spot ventrally and subapically on front femora; one postero-ventrally and one postero-dorsally between middle and apex of intermediate femora; and four conspicuous spots postero-ventrally on hind femora, one of these subbasal and three near the middle. There are additional vague setigerous spots apically and dorsally but they are too poorly defined to describe.

Size: male, length 2.4 mm., width (hemelytra) 1 mm.; female, length 2.3 mm., width (hemelytra) 0.95 mm.

Holotype male, allotype female, and 12 paratypes, Tarague, May 17, on Messerschmidia, Usinger ; one specimen, Ritidian Point, April 15, on ferns, TODO

Runs to adamsoni Knight in Knight's key to the Marquesan species (B. P. Bishop Mus., Bull. 142: 181, 1938) but with shorter second antenna! segment and longer rostrum. C. tahitica Knight is another closely allied species which has a shorter rostrum, slightly different dots on hind femora, and, presumably, no dots on the front and middle femora, since they are not mentioned in the description.
