MALLOPHAGA FROM BIRDS OF FORMOSA. 175 
margins short, each with a coloured swelling and a long hair; posterior 
margin truncate; marginal bands irregular, brownish. Metathorax short, 
trapezoidal ; lateral margins bare and diverging posteriorly ; posterior angles 
rounded, each bearing a hair and a fine prickle; posterior margin convex, 
angulated in middle, with eight long pustulated hairs in four pairs; marginal 
bands broad, present only on the lateral borders. Legs paler than body, with 
brownish marginal markings and a few scattered hairs. 
Abdomen oval, broadest at the fourth segment, posterior angles protrud- 
ing, bearing one to three hairs on segments Im-vIm. Dorsal surface of 
abdomen with four rows of short hairs in the median portion of segments 
I-VO, and one row of long hairs behind the spiracles on the posterior margin 
of segments II-vII. Segments I-v approximately equal in length, then 
successively shorter; the last segment round, entire, with numerous hairs. 
Lateral marginal bands brownish, well chitinized, entering into the segment 
preceding and curving directly backward to the posterior margin of the same ; 
transverse blotches, broad, pale yellowish brown, entirely across all segments, 
leaving uncoloured stigmatal spots and a narrow pale line along each posterior 
margin of segments. Genitalia distinct, reaching to the fifth abdominal segment, 
and the posterior end consits of a triangular median part and two short 
chitinous movable hooks. 
Gen. GONIOCOTES Burmeister. 
5. Goniocotes kurodai n. sp. 
(Plate X, Fig 4.) 
One male specimen was taken from Sphenocercus sororius, killed at Suisha, 
Distr. Nanto, May 3, and another from Graucalus rex-pineti shot at the 
same locality, May 4. 
This new species somewhat resembles Rudow’s Goniocotes carpophage,* 
but may be distinguished from that species chiefly by its larger head and 
broader abdomen.
