1. Platypus quadrilobus, sp. n. (Tab. IV. figg. 1, ¢; 1a, apical depression 
of the elytra.) 
Mas. Ferrugineo-piceus ; prothorace suboblongo, dense subtiliter punctato ; elytris ad apicem abrupte truncatis, 
truncatura concava, opaca, margine inferiore ad suturam emarginato, versus latera exciso, et in lobos

Long. 4°2 millim. 
Male. Variable in colour, from ferruginous to piceous, the underside and legs lighter. Front of the head 
subconcave, dull, with close fine reticulation, the epistomal border alone shining, punctured towards the 
vertex, and with a median shining impressed point ; median line of the vertex wide, shining, the sides 
with coarse strigose punctures. Prothorax a little longer than wide, the sulcus impressed anteriorly, 
surface with a slight transverse impression at the front of the sulcus, with very close reticulation and 
close fine irregular punctuation, becoming coarser towards the basal border. Elytra with shallow 
subsulcate strie, rather regularly punctured ; first and succeeding alternate interstices elevated, convex, 
shining along the middle, with fine irregular punctuation, remaining interstices tlat, dull and reticulate ; 
first interstice produced at the apex into a short spine, third and succeeding interstices with a common free
