In 1936 I gave no reference to the figure, which is pl. 9, fig. 1, female; 
while under P. k. subsimiles (p. 95) the reference to the figure should 
read pl. 9, fig. la (male genitalia), which is the only figure given for 
the race.

(male genitalia), 1986. (Host: Crypturellus soub inconspicuus.) 
A single female on C. s. mustelinus at Tierra Nueva, Sierra Perija, 
Colombia, is so very close to this form that there are no tenable grounds 
for its separation. While the two hosts are widely separated geogra- 
phically, they are nevertheless very closely related, and it is not strange 
to find that both hosts harbor exactly the same kind of parasite. As 
corroborative proof of this we have Strongylocotes s. subconiceps 
found on fwe races of Crypturellus soud. 
A male and a female taken on Crypturellus sow meserythrus, Cerro 
Tuxtla, Mexico, may also be referred to this subspecies. The 
measurements are exceedingly close, the only appreciable differences 
being the lengths of the abdomen and pterothorax. The former may 
vary owing to pressure in mounting, while the latter is difficult to 
determine, since the end of the mesometathoracic suture is not always 
clearly visible. The genital armature is also very close as to measure- 
ments and shape, as are the abdominal hooks. This form has the
