Mr. F. P. Pascoe on new Neotropical Carculionidce. 421 



Narrowly subelliptic, slightly convex, chestnut-brown, with 

 small, pale, silaceous, non-contigaous scales ; rostrum chest- 

 nut, smooth, except at the base ; antennae ferruginous, basal 

 joint of the funicle nearly as long as the two next together ; 

 prothorax with rounded, more or less remote glossy granules ; 

 scutellum subscutiform ; elytra seriate-punctate, punctures 

 scarcely approximate, interstices not raised ; legs and body 

 beneath with scattered pale yellowish scales, but the last 

 three segments of abdomen smooth except at the sides j meso- 

 sternum depressed. 



A narrower species than G. icni'formi's, more convex, with 

 comparatively longer elytra, and differently sculptured. 



Erethistes amplicollis. 



E. angustus, niger, nitidus ; elytris prothorace anguatioribiis, albo- 

 sexmaculatis, seriatim grosse punctatis; pedibus touuatis elongatia. 

 Long, Sg lin. 



Hah. Santo Paulo d'01iven9a. 



Narrow, black, shining ; elytra with two basal and two sub- 

 apical spots and the apex white ; rostrum pitchy, longer than 

 the prothorax, minutely punctured ; antennas ferruginous, 

 first joint of the funicle twice as long as the second, club 

 elongate elliptic; prothorax sensibly longer than broad, 

 regularly rounded at the sides, slightly convex, obsoletely 

 punctured, and with a few short, scarcely elevated, transverse 

 lines posteriorly ; scutellum punctiform ; elytra narrower 

 than the prothorax and not much longer, gradually narrowing 

 towards the apex, seriate-punctate, the punctures subtrans* 

 verse, a short white oblique spot at the base of each, another 

 behind the middle and the apex white; sides of the sterna 

 closely covered with buff-coloured scales. 



The nearest ally to this species is E. leucospilus, which is 

 much stouter in all its parts and with a normal relation of the 

 prothorax to the elytra ; the white spots are also more nume- 

 rous. 



EJytrocoptus inolifer. 



E. fuscus, opacus ; elytris amplis, humeris calloso-productis apiceque 

 late truncatis, linea arcuata determinata silacea ad latera altera- 

 que submarginali ornatis. Long. 6 lin. 



Hah. Nauta (Ecuador). 



Opaque dark brown, sides of the elytra with curved sila- 

 ceous lines ; rostrum rather stout ; antennae pitchy ; prothorax 

 transverse, rounded at the sides, scuteliar lobe slightly 

 pointed, the disk roughly punctured, the punctures largest in
