PLATYPUS. 103 
the description of P. datesi, ¢, Chap., a Brazilian species, but differs at least in one 
character, the shape of the scape, which in P. batesi is described and figured as a blunt 
isosceles triangle. 
18. Platypus salvini, sp.n. (Tab. IV. figg. 14,3; 14a, apex of elytra; 144, 
front.) 
Mas. Ferrugineo-piceus, elytris postice infuscatis; fronte concava; prothorace quadrato, in utroque sulci 
latere congerie punctorum minuta ornato; elytris sulcatis, interstitiis fere planis, latitudine vix alternatis, 
1°, 3°, 5° levibus in summa declivitate breviter spinosis, inde gradatim declivibus, ceteris punctatis, postice 
tuberculatis ; declivitate obliqua subangustata tuberculata, margine postico serrato. 
Long. 10 millim. ; 
Male. Piceous-red, the elytra infuscate. Front concave, areolate and rugose, with scattered deep punctures 
towards the vertex and mouth, with the median space of the vertex continued on to it as a slight carina, 
obliterated above the middle, epistoma raised and conjoined at the sides to the antennal fovex by a curved 
ridge. Prothorax quadrate, sulcus shallow, on either side of its anterior end is a patch of about six small 
punctures; surface with several slight impressions, especially one about the middle of either side, and one 
close to the median line near the apex, its punctuation irregular, close, and fine, stronger at the sides, base, 
and hind part of the suleus. Elytral sulci narrow, with a single row of confluent punctures; interstices 
finely granulate at the base, the granules extending farthest on the fourth interstice, slightly convex 
and scarcely alternate, the 1st, 3rd, 5th, and 7th shining, impunctate, and with a single sharp tubercle at 
the summit of the declivity, the remainder with scattered punctures, and with a row of smaller tubercles 
before the declivity, which is oblique, shining, punctured in the line of the sulci, and tuberculate along 
the Ist and 8rd interstices; postero-lateral processes small, declivous, entire, connected by a curved fold 
with the 3rd interstice, and separated by a notch on the hind margin from a small serrated lobe, external 
to an emargination at the suture. 
Hab. Guavemata, Cerro Zunil (Champion). 
Two examples. This large species belongs to the subdivision which includes the 
S.-American P. robustus, Chap., and P. parysi, Chap., but is considerably larger than 
either, with the elytral sulci finer, and the interstices entirely shining and less alternate. 
19. Platypus quinque-costatus. 
Platypus quinque-costatus, ? (lege 3), Chap. Mon. Plat. p. 149, fig. 65". 
Hab. Muxico, Toxpam (Sallé1); Guaremana, San Joaquin and Purula in Vera Paz, 
Duefias (Champion). 
Two examples from M. Sallé’s collection are typical, and Mr. Champion has obtained 
five others; but neither collector has taken any Platypus that can be the female of 
this species. 
20. Platypus porrectus. | 
Platypus porrectus, 3 (lege 2), Chap. Mon. Plat. p. 150, fig. 67 ‘ 
Hab. Panama, Volcan de Chiriqui (Champion).—Cotomsia?. 
A solitary example taken in Panama may be referred to this species, of which the 
male has not been described. Unfortunately no type-specimen has been accessible, 
and therefore, though the example corresponds with Chapuis’s description, its identity
