the apex, M-ith a bioad deep median furrow, which is continued on 

 to the forehead, and a short longitudinal impression on each side; 

 the interantcnnal area broadly excavated. Antennue with the 

 scape just reaching the hind margin of the eye, rather densely 

 clothed with narrov/ grey scales and with subrecumbent setae; 

 the funicular joints in order of length : 2, 1, 3, 4, (5, 6, 7), the apical 

 joints nearly as broad as long. Prothorax as long as broad, broadest 

 at the base, very gradually nai-rowed in front and with a shallow 

 apical constriction ; the basal and apical margins gently rounded, 

 the gidar margin rather deeply sinuate; the doisum with a broad 

 deep uneven conical median depression, enclosed on each side by a 

 sparsely punctate broad straight smooth costa, the external areas 

 less rugose and shallowiy impressed in front and behind. SctiteUum 

 oval, longer than broad, finely coriaceous, bare. Elytra oblong 

 ovate, the basal margins individually truncate and together forming 

 a gentle curve; the shoulders sloping, the sides parallel thence to 

 beyond the middle, the apices jointly rounded; the dorsal outline 

 almost fiat from the base to the top of the declivity, which has a 

 slope of 60''; the sutural area fiattened, and the punctures very 

 shallow, large, subconfluent and indistinct; interval 3 rather 

 strongly costate and curving inwards near the base, then becoming 

 less pronounced and much more rrregulai', and terminating at the 

 top of the declivity in a low rounded backwardly- projecting tubercle ; 

 int. 4 raised for a short distance behind the middle and connected 

 with int. 3 by the raised transverse septa ; int. 7 costate from the 

 base to the declivity; the scales small and overlapping; the setae 

 short and curved, numerous between ints. 3 and 7, and a small 

 short tuft of them just above the apex. Legs with subrecumbent 

 setae; the tibiae not denticulate internally, the hind pair shortly 

 mucronate; joint 2 of the front tarsi longer than broad. 

 Length, 13-5 mm. ; breadth, 5-25 mm. 



Ecuador : lower slopes of Antisana, 13,000 ft. {E. 

 Whymper). 



One of Whymper's specimens was placed in Pascoe's 

 collection with E. ivagneri, but, apart from the distinctions 

 given in the key, it differs markedly in the male genitalia, 

 the median lobe being less curved, much broader and much 

 less sharply pointed in praetcritus. 



Exorides equicaudatus, sp. n. (Text fig. 4.) 



(^. Integument black, with a few grey scales in the foveae; the 

 venter bare, with sparse pale short recumbent setae. 



Head impunctate, the forehead and vertex somewhat flattened;
