1917] McGregor—Eight New Mallophaga of the Genus Lipeurus 107 
abruptly to a narrow frontal margin bordered on each side by two 
shortish hairs. Between the trabecule, which are quite promi- 
nent, and the frontal border five prickles arise. Antennal sinuses 
hardly noticeable. Ocular projections barely discernible; ocular 
fleck conspicuous. Temple margins diverge slightly posteriorly 
to the squarish angles which bear a strong spine; a prickle arises 
from the eye, and two from the temples. Occipital margin almost 
straight, but with a weak median convexity. Antennal bands 
clearest just before the antennx, paling anteriorly and separated 
at front by the large, median, dark-bordered clear area which ex- 
tends back to the mandibles. Temples narrowly margined by 
blackish borders. Faint bands running backward from the tra- 
beculee and the mandibles unite posteriorly to form a W-shaped 
figure. A diamond-shaped occipital signature. Antenne con- 
ventional. 
Thorax one-fourth wider than long, prothorax rectangular with 
very slightly convex posterior margin. A short spine at each 
posterior lateral angle. Smoky-amber color with a median clear 
area, and with narrow, dark, underlying bands. Metathorax 
pentagonal, sides diverging strongly to the angulated posterior 
margin. A strong postulated spine at the lateral posterior angle, 
and four long, postulated hairs along each lateral third of the hind 
border. Color smoky-brown, with a median, vase-shaped, clear 
area. Legs smoky banded. 
Abdomen widely elliptical, widest on the fourth segment. Gen- 
eral color hyaline with a dorsal series of paired, sub-quadrate, 
brownish plates, and with lateral plates of slightly darker color 
on segments 2 to 7 inclusive; the dorsal plates on segment 1 larger 
and darker than others. Marginal hairs at posterior lateral angles 
as follows: ‘Two weak hairs on segment 3, two longer ones on seg- 
ment 4, two long hairs on each of segments 5, 6, 7 and 9, one long 
hair on segment 8. A median pair of long spines on segments 1 
to 8 inclusive. A pair of weak terminal hairs. Segmental sutures 
mostly invisible.
