The above species appear to be mere colour varieties of one

Acrydium tectitergum, sp. nov. 
Near subulatum, Linn. Fuscous or obscure fusco-ferrugineous, 
granulose; vertex wider than one of the eyes, distinctly produced, 
carinulae laterally subangularly reflexed, and little compressed, 
the front border convex, middle carinate, on each side elongate 
fossulate; eyes moderately small; head in profile obtuse angulate, 
the face strongly produced, convex, advanced equal to the width 
of one of the eyes; indistinctly sinuate at the median ocellus ; 
antennae very slender filiform, inserted between the lower border 
of the eyes and partly below. Pronotum anteriorly very obtuse 
angulate, posteriorly acute subulate produced beyond the hind 
femoral apices; dorsum tectiform, median carina of the pronotum 
forward distinctly compressed elevated cristate, above substraight 
from the sulci to the shoulders, then gently concavely sloping 
backward, substraight on the hind process; humeral angles ob- 
tuse; lateral carinae little compressed; prozonal carinae behind 
the anterior border shortened; posterior angles of the lateral lobes
