live))' few. Mouth parts prominent, and bearing a well developed 
triangular labium having three prominent spines on lateral margins. 
Antennae seven jointed, the fourth being the largest, the sixth the 
shortest. Beginning with the proximal segment they measure 
56-68; 32-36; 56-68; 52-56 28-40; 20-24; 28-32; micromillimeters 
respective^'. Chietotaxy and structure shown in figure. In some 
specimens sutures between i and 2, in others sutures between 3 
and 4, 5 and 6 are indistinct. The third and fourth are without 
spines, the remaining segments show spines as indicated in figure. 
The legs are well developed, and highly chitinized. The body 
when boiled in KOH gives reddish brown coloring matter and 
becomes clear, the legs however retain part of their chitine. 
'J'rochanter prominent, prothoracic leg in some specimens shows 
unusually long hairs, two on trochanter, one on coxa; hairs else- 
where as indicated in figure. Claw curved, with two stout knobbed 
digitules. The second digitule of claw seen only in the mesotho- 
racic leg. Tarsus bearing two long slender knobbed digitules. 
Chajtotax)’ and relative size.s. of segments shown in figure. 
Habitat. On the twigs of osage orange. May 18, 1898. These 
specimens were received from Clallin, Barber county, through the 
Honorable F. D. Coburn Secretary of the State Board of Agricul- 
ture. The twigs were thicklj- covered with scales but so thoroughly 
were the)' parasitized by chalcids and attacked by the larvK of a 
coccinellid that it was with difficulty that suitable material for 
study was obtained from material sent. These insects are widely 
separated from I. mtiiliiraniiii Ckll. Description of /. robiniariim 
Douglas is not at hand. I note however that a probable variety has 
been found in New Mexico* on osage orange. The parasites left no 
eggs for comparison, so even this remote clue is wanting. Professor 
Cockerell says: “It isn’t rohiniarnm. It is related, I think, to /.. 
filchii."

This scale at first glance resembles scale of L. kansascnse but upon 
close examination the smooth central boss is not so apparent, nor 
raised smooth ridge on each side of the boss. The legs and 
antenna' ])resent still greater distinctions. Scale of female, long,
