capite prothoraceque angustis, hoc elongato et basin versus angustato, elytris multo angustiore, irregulariter 
punctato ; elytris fortiter punctatis, ad apicem fere levigatis. 
Long. 6 millim. 
Hab. Mexico, Cordova (fHége). 
Though closely allied to P. lacertinus this insect is no doubt distinct, and differs as 
follows: it is smaller, the head and thorax are still narrower, the terminal joint of 
the maxillary palpus is larger, the eyes touch the hind margin of the head, and the 
thorax is not so broad in front and therefore less strongly narrowed behind. The 
unique example has lost its antenne. 
3. Palaminus longicollis. 
Angustus, elongatus, niger ; antennis, palpis pedibusque pallide flavis, palporum articulo ultimo majore; capite 
mediocre, oculis magnis; prothorace elongato, basin versus angustato, elytris multo angustiore; his crebre 
punctatis, ad apicem fere levigatis. 
Long. 74 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Of this species also we have obtained only one example; though allied to the two 
preceding by the long slender thorax, it is undoubtedly distinct. Antenne mutilated, 
but the third, fourth, and fifth joints are very long. Head moderately large, with 
convex eyes not attaining the hind margin; terminal joint of the maxillary palpus 
extremely large. Thorax rather longer than broad, much narrower than the elytra, 
strongly narrowed behind ; its punctuation like that of the head, moderately coarse, 
not confluent. Elytra very elongate, rather closely punctate. Hind body unusually 
definitely sculptured ; terminal styles very long, strongly sinuous. Legs slender. 
4. Palaminus validus. 
Hlongatus, niger; antennis, palpis pedibusque pallide flavis, palporum articulo ultimo magno ; capite sat lato; 
prothorace sat elongato, basin versus angustato, minus dense punctato; elytris fortiter punctatis, ad 
apicem fere levigatis. 
Long. 84 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species has the front tibie and tarsi considerably broader than in either of the 
species above described; the thorax is a little broader, its punctuation and that of 
the head less close and deep; the eyes are moderately large, and do not attain the hind 
margin. The elytra are about twice as long as the thorax. Two mutilated examples. 
5. Palaminus cognatus. 
Elongatus, niger ; antennis, palpis pedibusque pallide flavis, palporum articulo ultimo magno; prothorace sat 
elongato, basin versus angustato, irregulariter subobsolete punctato ; elytris fortiter punctatis, ad apicem 
fere levigatis. 
Long. 8 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet, San Feliz (Champion).
