tivel}' few. Mouth parts prominent, and bearing a well developed 

 triangular labium having three prominent spines on lateral margins. 



Antenuce 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; ^^"32; micromillimeters 

 respectively. Chaetotaxy 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 highlv chitinized. The body 

 when boiled in KOH gives reddish brown coloring matter and 

 becomes clear, the legs however retain part of their chitine. 

 Trochanter prominent, prothoracic leg in some specimens shows 

 unusual!)' 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. 

 Chietotaxy and relative sizes of segments shown in figure. 



Habitat. On the twigs of osage orange. May 18, 1898. These 

 specimens were received from Claliin, Barber county, through the 

 Honorable F. D. Coburn Secretary of the State Board of Agricul- 

 ture. The twigs were thickly covered with scales but so thoroughly 

 were they parasitized by chalcids and attacked by the larvre of a 

 coccinelliei that it was with difficulty that suitable material for 

 study was obtained from material sent. These insects are widely 

 separated from / nhxcliirai-tiin Ckll. Description of f,. rohiniariiiii 

 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 rohiiiiaiKiii. It is related, 1 think, to /.

This scale at first glance resembles scale of /. kansasciise 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- ]i resent still greater distinctions. Scale of female, long,

 slightly extended. Some specimens show slight elevation on cen-
