albo-tomentosis : capite vix exserto sed latissimo et fronte lon- 
gissima, mandibulisque valde elongatis; oculis ut in gen. T'etraope 
divisis ; thorace antice lato, postice angustato, dorso gibboso, basi 
constricto ; antennis basi ciliatis, scapo longissimo, clavato ; elytris

Macas, Ecuador (Buckley). 
A peculiar species in form, colour, and clothing, but not 
sufficiently different to be separated generically from Amphio- 
nycha, its peculiarities being those of A. dimidiata carried a 
little further. The lateral carina is marked as a distinct 
angle separating the dorsal surface of the elytra from the epi- 
pleura; but it does not form a rib; or if it does, the elevation 
is concealed by the dense black pile of the elytra. The 
yellow colour of the thorax and apical belt of the elytra is 
associated with pilosity of a very peculiar nature, which I 
have not noticed in any other species; it resembles the texture
