PLATYPUS. 97 
I have not seen either sex of this species, which is very nearly allied to the preceding. 
The apical spines of the Ist, 3rd, 5th, and 7th interstices in the male are described 
and figured as of equal length, and nothing is said about any excision at the tip of 
the posterior process, which is figured as being obtusely pointed. 
4. Platypus putzeysi. 
Platypus putzeysi, 3 (lege ¢), Chap. Mon. Plat. p. 117, fig. 39°. 
Hab. Mexico, Toxpam, Oaxaca (Sallé!); Guaremana, Purula (Champion). 
The single female example taken by Mr. Champion agrees well with the type from 
Sallé’s collection. No male form can be associated with it. 
5. Platypus filiformis. 
Platypus filiformis, 3 (lege 9), Chap. Mon. Plat. p. 116, fig. 38°. 
Hab. Mexico }. 
The species does not occur in our collections; and I have seen only the typical 
examples from Chapuis’s collection, These are two in number, and it is noteworthy 
that the single pore described by Chapuis on either side of the prothoracic sulcus is 
replaced in one specimen by a series of three pores.
