58 HELOTA LUGUBRIS. 
Prothorax widest at the base, slightly narrowing towards 
the front margin in faintly convex sides; the front angles 
but slightly produced; the base bisinuate, the lateral angles 
acute, the median lobe rounded and with a punctiform 
impression; the disk strongly and rather regularly densely 
punctured, with the usual slightly raised nearly impune- 
tate patches, viz. a mesial forked one, extending from the 
base to the front margin, an elongate basal one on each 
side of the former, and a smaller ‘one in front of the 
basal patches. The scutellum is small, subtransverse, and 
almost invisibly impressed along the middle. The bronze 
coloured lateral portions of the prosternum show a few 
distinct punctures. An impressed line runs all along the 
middle of the metasternum. 
Elytra parallel, narrowing in regularly curved lines just 
behind the posterior convex yellow spot and here provi- 
ded with three angular notches on the right and two 
similar ones on the left elytron; the apices are broadly 
conjointly rounded and slightly dehiscent at the suture, 
without distinct sutural spine. Each elytron with ten very 
regularly punctured striae of which the 4th and 5th are 
interrupted by the yellow convex spots and are not con- 
tinued behind the posterior ones; the punctures of the 
striae gradually increase in size from the first (sutural) 
to the last (marginal) one; the interstices between the 
Ist and 4th striae are subcostate (more strongly raised, 
however, towards the apex); the following interstices nar- 
rower and alternately more strongly raised as well as 
extending farther backward; the apical portion of the 
6th interstice, which does not reach the apical margin, is 
more strongly raised than any of the others, and conse- 
quently very obvious. The epipleurae are impunctate. 
Abdomen smooth and shining; the basal segment with 
a trace of a longitudinal impression at the base; the apical 
segment strongly transverse, its apical margin slightly 
convex in the middle, at both ends of the convex line a 
small though distinet impression. 
The legs are smooth and impunctate; the anterior tibiae
