I do not think this species can be confused with any other described Ciibi- 
corhynchus; its very short rostrum flattened above (or rather having its entire 
upper surface gently and evenly concave), transversely quadrate, and as wide as the 
head is behind the eyes—with the crests appearing as prolongations of the rostrum 
and directed obliquely hindward and outward, and looking like set-back ears of 
some animal—furnishes very unmistakeable characters. The strong, even tuber- 
culation of the prothorax is also highly characteristic.

nigra, squamis pallidis plus minusve vestita (exemplis typicis fere glabris) et tuber¬ 
culis omnibus setas obscuras ferentibus ; rostro brevi supra ruguloso, quam caput 
paullo angustiori, in medio longitudinaliter anguste profunde canaliculate, dorso 
utrinque extra sulcum in parte posteriori a sulco brevi profundo in lobis 2 divisa ; 
capite obsolete tuberculato, convexo; prothorace quam longiori parum latiori, 
tuberculis obtusis sat grossis crebre instructo, antice quam postice vix angustiori, 
lateribus rotundatis, latitudine majori ante medium posita elytris tuberculis 
obtusis crebris valde rugulosis, his plus minusve seriatim positis, interstitiis obscure 
foveatis, humeris et tuberculorum serie tertia antrorsum fortiter tuberculiformibus, 
apice suturali minute acute producto. 
Maris segmentis ventralibus setis erectis sat brevibus minus crebre vix vittatim 
vestitis, segmento basali late leviter concavo. 
Feminie abdomine glabro lequali. Long. 4—5|- 1. Lat. —2i 1. 
I have some hesitation in referring this insect to Atychoria^ because the genus 
is known to me only by description ; but I do not think there is much doubt about 
it. Atyc/ioria is notable among the characterised genera of Amy derides through 
its occupying an intermediate position between the groups with antenme having 
short and long antennal scape, its scape reaching back just beyond the front 
margin of the eye.
