98 RHYNCHOPHORA. 
Male. Reddish-pitchy, with the elytra black towards the apex. Front of the head subconcave, coarsely and 
rugosely punctured, with a median shining impressed point. Prothorax oblong, the median sulcus 
widened in front and continued by an impressed line nearly to apex ; the punctuation irregular, fine, and 
rather close over the anterior half and sides, stronger on either side of the median line, scantier behind 
and wanting round the sulcus, the basal border strongly punctured. Elytral sulci narrow in the middle, 
deeper at the extremities; 1st and succeeding alternate interstices not strongly raised, shining and 
sparingly punctured, the remaining interstices shining in the middle, the extremities alone punctured or 
tuberculate; apical spines of the 1st, 3rd, 5th, and 7th interstices successively decreasing in length, those 
of the 8th and 9th about equal in length to the 7th; declivity regularly convex, dull, with shining 
punctures in the lines of the sulci, the carinate interstices indicated by feeble elevations, the lateral angles 
shortly produced. Fifth abdominal segment armed with a pointed tubercle. 
Hab. Guatemata, Cerro Zunil (Champion). 
This species, of which a single male was taken by Mr. Champion, is allied to 
P. auritus, but is distinguishable from it and its nearest allies by the absence of any 
distinct elevations on the surface of the apical declivity and by the well-marked 
tubercle on the last abdominal segment.

This large species is represented in our collections by three male examples *. 
10. Platypus exaratus, sp. n. (Tab. IV. fig. 5, apex of elytra, ¢ .) 
Ferrugineus; prothorace quadrato, dense punctato. 
Mas. Elytris ad apicem piceis, late sulcatis, interstitiis angustis, nitidis, 1°, 3°, 5°, 7°, 8°, 9° posterius carinatis, 
carinis in declivitate summa abrupte angulatis. 
Long. 6:3 millim. 
* The following species, not from Central America, is so like P. reichei as to be suitably described here : — 
Platypus fortis, sp. n. 
Mas. Niger, fronte antice subnitida, obsolete punctata, postice rugosa; prothorace latitudine paullo longiore ; 
elytris fortiter sulcatis, sulcis distincte punctatis, interstitiis 1°, 3°, 5°, 7°, 8°, 9° elevatis, usque ad decli- 
vitatem nitidis, 1° in declivitate summa spinula obtusa intus curvata armato, ceteris parce punctatis versus 
apicem tuberculatis. 
Long. 11 millim. 
Closely allied in size and shape to P. reichei, the front of the head more finely rugose and shining over the 
mouth, Prothorax relatively a little longer, its sulcus preceded by a well-defined median smooth line ; 
the lateral punctures fewer and stronger. Carinate interstices of the elytra entirely smooth towards the 
declivity, above which the first pair is produced to form two short, blunt, incurved spines; the non- 
carinate interstices less rugose, with very few punctures and three or four tubercles before the declivity ; 
lateral protuberances of the declivity smaller and more pointed ; the apical margin furnished with a small 
tubercle near the suture.
