Type: Catalogue No. 21366. U.S. Nat. Mus. 
Lipeurus bishoppi sp. nov. 
Four males and one female (Bishopp No. 4995) from domestic 
geese, Hamburg, Miss., December 3, 1915, coll. W. E. Dove. 
This species is probably nearest L. temporalis N., of the mer- 
ganser, and it also bears some resemblance to L. squalidus N., of 
ducks, and to L. constrictus Kell., of scoters. 
Description of Male. Total length, 3.05 mm.; length of head, 
.664 mm.; length of prothorax, .186 mm.; length of metathorax, 
431 mm.; length of abdomen, 1.771 mm.; width of head between 
eyes, .442 mm.; width of prothorax, .326 mm.; width of meta- 
thorax, .431 mm.; width of abdomen, .524 mm. 
Head just half again as long as wide, forehead converging to the 
sharply rounding front, antennal sinuses shallow, trabeculee 
rather prominent, ocular flecks lacking, temples converging from 
the eyes to the concave occiput. Six heavy spines along the lateral 
half of the front and anterior half of forehead, the third of which 
is heaviest; a short hair before trabecular, a hair on the eye, four 
prickles along the temples and a long hair on the hind third of 
same. Antennal bands occur as thin, hyaline borders which 
before the trabecule give off a short, swollen, posterior-directed 
bar, and at the hind border of the antennal sinuses sends off a 
similar, inward-pointing bar, general color pale, smoky amber. 
Antenne strong, reaching to the middle of the prothorax, seg- 
ment 3 with a strongly developed hooked process. 
Thorax three-sevenths again as long as wide. Prothorax rec- 
tangular, front margin quite strongly convex, hind margin weakly 
convex. Narrow, brownish, submarginal bands curve backward 
and inward, nearly meeting on the median line; coxal markings 
showing faintly through; general color pale amber. <A _prickle 
and a short hair at the posterior lateral angles. Metathorax 
quadrilateral, slightly constricted near the middle, posterior mar- 
gin weakly concave. General color same as prothorax, with a 
brown-bordered, black spot at each lateral constriction. Six long 
stiff hairs on each lateral third of the hind margin. Legs strong, 
brownish-yellow.
