Platypus haagi, 8 2 (lege 2 &), Chap. Mon. Plat. p. 178, fig. 84°. 
Hab. Mnxico, Toxpam (Sallé1), Jalapa (Hodge); Panama, Volcan de Chiriqui 
(Champion). 
Our collection contains types of both sexes from that of M. Sallé. A specimen 
from Jalapa is the only other Mexican example; but Mr. Champion obtained a good 
series on the Volcan de Chiriqui in which the males preponderate in the ratio of four 
to one. 
31. Platypus dejeani. 
Platypus dejeani, g 3 (lege 3), Chap. Mon. Plat. p. 186, fig. 97°. 
Hab. Mexico, Acapulco (Hége); Britise Honpuras (Blancaneaux).—Gutana ! ; 
Brazil. 
This species as delimited by Chapuis is, in the male, a little more robust than its 
successors, the apical process is evidently shorter than broad, the margin between its 
superior and inferior spines is straight, the spines themselves of equal length. I 
possess a specimen from Mexico, labelled by Chapuis himself, which is closely 
approached by those from Acapulco and British Honduras. 
At the same time I can scarcely, even with the assistance of types, separate it with 
any confidence from P. rugulosus. Examination of long series of males from different 
places shows that those from each place have a certain common resemblance, but not 
that absolute agreement in the structure of the apical spines by which alone they can 
be separated. How far these forms indicate more than a single species cannot be 
settled, but by the collection in different localities of series carefully labelled for that 
purpose and marked with the actual date and place of capture. The numerous males 
of this and the next species in our collections are accompanied with very few females, 
and those principally from Zapote in Guatemala; so that it is impossible to see 
whether the slight indications of differences in one sex are accompanied by constant 
though equally slight differences in the other.
