64. Mr. Walter F. H. Blandford on the 
elevata, lateraliter versus apicem muricato; elytris prothorace 
plus quam duplo longioribus, subcylindricis, striato-punctatis, 
interstitiis usque ad declivitatem transverse rugosis, lo, 30, 50, 7o 
in declivitate elevatis, seriatim tuberculatis, ceteris punctatis. 
Long. 3°4 mm. 
Junsal; one specimen. 
Oblong, black, with elytra obscurely piceous. Head with 
labrum pitchy, separated by a transverse depression from front, 
which is flattened, shining, strongly punctured and glabrous ; 
vertex finely reticulate. Antenne ferruginous, club small, pointed, 
sutures transverse. Prothorax transverse, base biconcave, 
depressed, scarcely produced in middle, sides strongly rounded ; 
surface convex, finely reticulate and with strong asperate punctua- 
tion somewhat weaker at base, with traces of a central elevation ; 
sides tuberculate before apex. Scutellum small, punctured. 
Elytra wider than prothorax and two and a half times as long, 
their bases convex, overlapping thorax, sides parallel to middle, 
then rounded to apex, surface convex cylindrical, strongly 
declivous behind, with strong punctured striw, the punctures 
round and distinct ; all interstices transversely rugose and punc- 
tured to middle, 1, 3, 5, 7 and 9 after middle with a series of 
transverse asperities which become strongly tuberculate on the 
apical declivity, where the interstices are elevated ; alternate 
interstices not asperate behind middle, multipunctate. Underside 
black, punctured, shortly pubescent, metasternum with a deep 
longitudinal impression, its episterna not very narrow ; abdomen 
scarcely convex longitudinally, its terminal segment rugose. 
Tibia spined externally. 
In the flatness of the abdomen this species differs 
from the majority of the genus, except the sub-genus 
Pteleobius, Bedel, to which it is not related.
