60 TRAVELS AMONGST THE GREAT ANDES. 



First abdominal segment slightly longer tlian the four following which are 

 almost equal in length. Legs moderately lohust, tarsi dilated, claws feebly 

 dilated near the base. 



The males with an accessory segment visible from above. 



After considerable hesitation I have come to the conclusion that this 

 genus is best placed near Nitidula and Epurma. The dentate mandiljles, 

 sharply pointed metasternal episternum, and the sexual character will suffice 

 to distinguish it from these and the allied genera. 



2. Pleiironeces montanus, sp. n. 



Hab. Antisanilla to Pinantura (11,000 feet). 



Elongate, depressed, slightly Ijroader behind than in front, black, shining, 

 the elytra rather dark brownish testaceous. Head moderately strongly and 

 not very closely jjunctured ; the epistoma only punctured at the base. 

 Antennae reddi.sh testaceous, the club pitchy black. Prothorax much 1 iroader 

 than long, moderately convex, finely margined, as strongly and about as 

 closely punctured on the disc as the head, the punctures slightly closer near 

 the sides ; all the angles obtuse ; the sides arcuate. Scutellum large, finely 

 punctured at the liase, the sides ol)lique and slightly arcuate, the apex 

 rounded. Elytra about one-third longer tlian broad, truncate behind, not 

 very convex, at the base as broad as the prothorax, slightly broader pos- 

 tei'ioily, finely margined at the sides, icither strongly and closely i>unctui'ed ; 

 humeral angles rather prominent ; outer apical angles strongly and sutural 

 angles feebly rounded. Pygidium densely l)ut not very strongly punctured, 

 sparingly clothed with short bristly pubescence. Underside pitchy black ; 

 prosternum finely punctured and coriaceous ; mesosternum, metasternum 

 and abdominal segments rather more strongly and regularly punctured. 

 Legs brownish testaceous, femora somewhat darker. Length, 4^ mm. ; 

 greatest width, 2^ mm. For Figure see the accompanying Plate.

RHYNCHOPHORA. 



Amongst the Rhynchophora in Mr. Wliymper's Ecuadorian collections, the 

 two large families Otiorrliynchidce and Curculionidce are, as might be expected, 

 ])etter rejiresented than any others, twenty-eight of the thii'ty-four species
