Two females, two males, and two immature individuals (Mc- 
Gregor No. 101, Washburn No. 166) from sand-hill crane (Grus 
mexicana), western.Minnesota, April 15, 1894. . 
This species is nearest L. hebreus N. (from Grus cinera and G. 
pavonina) from which it is very distinct. It also superficially 
resembles LZ. toxoceros N. which is from an entirely different host. 
Description of Male. 'Total length, 4.76 mm.; length of head, 
1.045 mm.; length of prothorax, .357 mm.; length of metathorax, 
.797 mm.; length of abdomen, 2.585 mm.; width of head across 
temples, .907 mm.; width of prothorax, .660 mm.; width of meta- 
thorax, .962 mm.; width of abdomen, .990. 
Head slightly longer than wide, rather abruptly narrowed ante- 
riorly, with a truncate frontal margin, antennal sinuses very 
shallow, temples some what rounding, eyes strongly projecting, 
hindhead widest half way between the eyes and the posterior angles, 
occipital margin strongly concave, four long marginal hairs and 
two short ones before the antennal angle, a prickle arises from the 
eye, one longish hair and five prickles on the temporal margin, 
and a pair of prickles arise dorsally from the forehead; head pale, 
antennal bands arise just before the antennz and are lost in the 
colored areas which extend laterally from the mandibles, but 
reappear as narrow borders behind the eyes. What appear to be 
faint occipital bands extend toward the bases of the mandibles. 
Antenne with segment 1 greatly swollen and equal to all the other 
segments; segment 3 with a dorsal, distal appendage and with a 
dorsal, proximal, annulated gland.
