Mr. F. P. Pascoe on new Neotropical Curculionidce. 179 



Camptochirus angustus. 



C. fuscus, sublinearis ; elytris elongatis, parallelis, prothorace vix 

 latioribus. Long. 2 lin. 



Hah. Columbia. 



Sublinear, dark brown, with scattered minute white hairs ; 

 rostrum twice as long as the head ; antennas fulvous, inserted 

 behind the middle, first and second joints of the funicle equal 

 in length ; prothorax slightly longer than broad, narrowed 

 anteriorly, and rather coarsely punctured, towards the apex 

 two large but slightly elevated tubercles ; scutellum nar- 

 rowly elongate, covered with white hairs ; elytra parallel, 

 more than twice as long as broad, flattish above, somewhat 

 truncate and abruptly rounded behind, punctate-striate, the 

 punctures linear with bluish intervals ; body beneath glossy 

 brown ; anterior tarsi and intermediate and posterior tibiee 

 and their tarsi fulvous. 



A remarkable form, but with scarcely sufficient characters 

 to warrant generic separation. 



Mnemyne. 



Rostrum elongatum, arcuatum, basi ampliatum; scrobes pone medium 

 incipiunt. Antenna graciles ; scapus oculum haud attingens. 

 Prothorax normalis, basi bisinuatus. Elytra subcordata, hume- 

 ris carinatis. Rima pectoraHs usque ad abdomen protensa, apice 

 aperta. Pedes elongati ; femora dentata ; tibiee recta;, com- 

 pressee, unguiculatse ; tarsi breves ; ungues simplices, divaricati. 

 Abdomen segmentis duobus basalibus ampliatis. 



This genus is unique among the Zygopinse in having the 

 pectoral canal prolonged on the metasternum, and termi- 

 nating close to the first abdominal segment. In other re- 

 spects there is no structural difference, except of a secondary 

 character ; but the whole aspect and colour of, at present, the 

 only species, is highly peculiar. 



Mnemyne viduata. 



M. ovalis, nigra subnitida ; antennis ferrugineis ; scutello niveo- 

 squamoso. Long. 2\ lin. 



Hab. Para. 



Oval, black, with few scales; head depressed above between 

 the eyes, the latter with the margin concave on each side of the 

 depression, contiguous in front ; rostrum slender, smooth, 

 angular and punctured at the base ; antennas ferruginous :, 

 scape short ; funicle with the second joint about four times 

 the length of the first, the third and fourth equal and toge- 

 ther as long as the first, the last three shortly turbinate:
