634 SEEEIOOENIA. 



Sixteen specimens, all but one from the Atlantic slope. This little species is allied to 

 P. ebenina, but it is larger and broader, and reddish-brown or rufo-testaceous in colour ; 

 the upper surface is more closely punctured, and somewhat thickly clothed with short 

 pruinose pubescence ; and the antennas are testaceous, with from two to five of the 

 intermediate joints more or less infuscate in both sexes. One of the specimens in the 

 Salle collection is labelled with the MS. name Ptilodactyla convexicollis, Chevr. The 

 single example, a large female, from Cerro Zunil has the antennas entirely testaceous. 



9. Ptilodactyla cucullata. 



$ . Elliptic, short, convex, shining, clothed with short fine brownish-cinereous pubescence ; black, the antennae 

 black or brown, the legs piceous with the tarsi testaceous, or entirely testaceous ; the upper surface very 

 finely, somewhat thickly punctate, the under surface more coarsely punctured. Head broad, the eyes 

 rather small; antennae reaching to a little beyond the middle of the elytra, rather slender, the joints from 

 the fourth serrate. Prothorax short, broad, transversely convex in front, acutely margined at the sides 

 and apex, abruptly compressed at the sides anteriorly, widest before the base, the sides rounded 

 and somewhat explanate, converging in front, the hind angles acute ; the base trisinuate, feebly 

 denticulate, and with a short projecting tooth in the centre. Scutellum with a deep notch in the centre 

 in front, and usually with a narrow shallow median sulcus. Elytra short, at the base not wider than the 

 base of the prothorax, broadly and acutely margined at the sides, compressed laterally below the humeri, 

 subparallel to about the middle, and a little produced at the apex, with a short, very deeply impressed, 

 sutural stria at the base. 

 Length 3-3j, breadth l|-lf millim. 



Bab. Mexico, Teapa in Tabasco (Salle, H. H. Smith) ; British Honduras, Belize 

 (Plancaneaux) ; Guatemala, Zapote (Champion) ; Honduras (Salle). 



Five specimens, all females. This species approaches P. convexicollis ; but differs 

 from it, apart from its smaller size and black colour, in having the thorax more acutely 

 margined at the apex and strongly compressed at the sides anteriorly, the scutellum with 

 the median sulcus shallow or obsolete, &c. The more pubescent body, the prominent 

 anterior margin of the thorax, the rugulose and less deeply notched scutellum, the 

 deeply impressed short sutural stria, &c, distinguish it from P. ebenina, which it 

 resembles in size and colour. The specimen in the Salle collection is labelled with the 

 MS. name Ptilodactyla cucullata, Chevr. 



10. Ptilodactyla canaliculata. 



Oblong-elliptic ( <$ ), oblong-oboval ( $ ), narrow, flattened above, moderately shining, thickly clothed with 

 short fine pallid pubescence ; rufo-piceous, the base and suture of the elytra more or less ferruginous, the 

 eyes black, the antennae, palpi, and legs testaceous. Head densely punctured, the eyes large and prominent 

 in the male, smaller in the female ; antennae long and rather slender, the joints 4-10 each with a short 

 ramus in the male and serrate in the female. Prothorax short, transversely convex in front, acutely 

 margined and rounded at the sides, widest before the base and narrowed anteriorly, the hind angles acute ; 

 the base trisinuate, feebly denticulate, and with a short projecting tooth in the centre; the surface closely 

 and rather coarsely granulate-punctate in the male, the punctuation more diffuse in the female. Scutellum 

 rugulose, deeply notched in the centre in front, and with a well-defined median sulcus extending thence 

 to the apex. Elytra moderately long and considerably wider than the prothorax in the female, shorter 

 and narrower in the male, depressed on the disc below the base, acutely margined at the sides, the humeri
