anticus paullo altiori; protliorace quam longiori^ vix latiori, antice quam postice 
sublatiori, supra planato, canaliculato, pone marginem anticum et ante basin 
transversim profunde sulcato, disco minus crebre tuberculis obtusis instructo, parte 
ante sulcum anticum tuberculis majoribus transversim positis ornata, laterum parte

parvis conicis (in seriebus circiter 9 confertim dispositis) instructis, his inter se

Maris segmento ventrali basali concavo, 2° in medio planato, apicali grosse

Feminie abdomine convexo; segmento ventrali apicali multo minus grosse

This species is very distinct from any other known to me by the even sculpture 
of its elytra, which consists of rows of closely-placed small tubercles of almost 
equal size and shape, those about the shoulder and the upper part of the hind 
declivity being, however, a little stronger than the rest, the intervals between 
these rows being gently concave and traversed by numei’ous transverse wrinkles. 
The elytra ai'e thus much more like those of a Cubicorhynchiis than of most 
Acantholophi. The head and prothorax are much like those of A. p/anicollis, 
Waterh., from which they differ, however, in the lateral ridges of the rostrum 
being continuous, the head not tuberculate between the eyes and the prothorax 
more elongate with stronger lateral tubercles. It may be distinguished from A. 
granu/atiis, Sloane, which it resembles, by {inter alia) the granules on its elytra 
running in single (not double) rows.
