angles of the emarginations prominent. LElytral sulci strongly punctate, continued to apex; bases of the 
first five interstices granulate, except the 3rd, which is punctured; 1st, 3rd, 5th, 7th interstices wider, 
convex, shining, subimpunctate, declivous behind, with two (the 7th with one) spinous tubercles on the 
declivity ; remaining interstices punctate, obsoletely tuberculate towards apex ; declivity oblique, 
narrowed, its lateral angles produced into two oblique subquadrate lobes, their outer margins the higher, 
their outer angles conjoined by a ridge to the 3rd interstice ; apex deeply emarginate. Last ventral 
segment transversely impressed. 
Female. Front dull and sericeous towards the mouth, with scattered minute shining punctures, and an elevation 
situate between two lateral impressions, above with lines of coarse oblong punctures radiating from the 
eyes, and a median longitudinal elevation, marked by an incised line; vertex shining, the median space not 
elevated. Prothorax as in the male, but dull, sericeous, with fine scattered punctures before the middle, 
and the hinder half subimpunctate; sulcus with two adjacent patches, each of about twenty punctures. 
Elytral stria wide, shallow, multipunctate ; interstices granulate at base, rugose, and subasperate at; 
apex, the elevated interstices subnitid and impunctate, the others narrow and closely punctured ; apical 
depression widely impressed below, granulate and hairy, its sutural margin longer than the lower border 
of either elytron. 
Hab. Guaremata, Sinanja in Vera Paz (Champion). 
A very fine and distinct species, of which but a single pair was taken. 
17. Platypus dolabratus, sp.n. (Tab. IV. figg. 12, ¢; 12a, front; 124, apex 
of elytra: 13, 2; 154, front.) 
Mas. Piceo-niger ; fronte supra sparsim grosse punctata; elytris anguste sulcatis, interstitiis planis nitidis, 
3° et 5° paullo latioribus, 1° et 3° gradatim declivibus, elevatis, tuberculatis, hoc extus curvato et cum plica 
processus postici declivis elongati conjuncto. 
Long. 10 millim. 
Fem. Fusco-ferruginea; fronte subconcava pre verticem areolata; scapo tumido ; prothorace subquadrato, parce 
punctato; elytris sulcatis, interstitiis subconvexis, ad basin punctatis, 3° et 3° subelatioribus. 
Long. 9°5 millim. 
Male. Piceous-black, limbs rufescent. Front concave, subsulcate from vertex to a median impressed point, 
dull, with fine shining punctures, closer towards the mouth, and scattered deep punctures towards the 
sides. Prothorax nearly quadrate, the punctuation fine, close in the middle of the disc; sulcus short, 
widened behind, with two small punctures on either side to represent the groups found in allied species. 
Elytral sulci shallow, interrupted; interstices shining, flat, base of the 2nd punctured, of the 4th 
granulate, 3rd and 5th somewhat wider throughout; declivity gradual, with the 1st and 3rd interstices 
carinate and tuberculate, the former not reaching the apex, the latter produced out over the apical 
process to form a tooth on its outer side, apices of the three following interstices with a few tubercles ; 
postero-lateral angles produced downwards and backwards to form the apical processes, the sutural angles 
slightly produced. 
Female. Fusco-ferruginous, elytra lighter, metasternum and abdomen testaceous. Front subconcave, dull, and 
areolate from the vertex to a curved line joining the antennal fovee; below subconvex, shining, with 
two to six deep punctures along the oral border; scape very convex, and swollen below. Prothorax 
subquadrate, the sulcus fine, preceded by an impressed line, hind angles of the emarginations impressed ; 
punctuation fine, diffuse, closer round median line, and stronger round the margins. Elytral sulci 
moderately deep, with shallow crowded punctures; interstices subconvex, subalternate, scarcely punc- 
tured, rugose before apex, base of the 3rd carinate; apical depression triangular, closely tuberculate. 
Hab. Panama, Bugaba (Champion). 
Three examples. ‘The male is distinct from any other described species in the 
structure of the apical portion of the elytra. The female answers very closely to
