HYPOCRYPTURELLUS CONICEPS subspecies 
Three females of this species were taken on Crypturellus cinna- 
momeus sallaei, collected by the author at Tres Zapotes, Veracruz, 
Mexico, the status of which cannot be satisfactorily determined with- 
out the male sex. A careful comparison with the females of all the 
known races shows that the Mexican specimens may be separated from 
all of them except obsoletus, either on size, proportions, or metatho- 
racic structure. They are so close to obsoletus in all these characters 
that I hestitate to give them a name without having seen the genital 
armature. When the males are available for study they will doubt- 
less be found to differ as regards genitalia.
