[March-June 
ginal areas opaque, with a C-shaped black macula in posterior 
corners; front margin sinuate, anterior angles obtuse, broadly 
rounded to posterior angle (broadest part of prothorax), thence 
obliquely truncate to base, latter nearly straight; a median 
impressed line extends from the front margin to center of the 
disc (this line extending the full length of the pronotum in the 
female). Scutellum heart-shaped, with fairly large, close punc- 
tures on the base. Elytra obovate, humeri rounded, broadest in 
the basal third, posterior gently rounded, with two feebly im- 
pressed lines, between the humeri and scutellum; of the same 
color as prothorax, but more shining, margins and suture black; 
a lateral, orange-yellow macula extends diagonally from hu- 
merus to within one and one-half millimeters of the suture and 
apex. Surface of the head, prothorax and elytra with remote 
punctures, those on the head largest. 
Beneath slightly darker than on the dorsum, feebly shining; 
anterior tibiae bifurcate at tip, and not as broad as in the female, 
with two strong spines in the distal half; intermediate and 
posterior tibiae linearly sculptured, spineless; femora remotely 
punctured, each puncture bearing a short golden seta; ab- 
dominal segments margined in black, finely punctured. 
Dimension: Length (excl. mandib.) 22.5 mm; mandibles 3 mm. 
Head 7.75 mm. wide; 4.5 mm. long (excl. mandib.) 
Prothorax 11.5 mm. wide; 6.0 mm. long (at middle) 
Elytra 11.25 mm. wide; 14.25 mm. long 
Allotype: $ , Bangkinang, Sumatra, in the Museum of Com- 
parative Zoology, Cambridge, Mass. 
The female holotype, described by Dr. Didier, does not differ 
to any extent from the male; in habitus it is slightly broader, 
resembling much the common Javanese laticollis, to which 
group it phylogenically belongs. The range of the insect, un- 
known to Dr. Didier, is now ascertained to be Sumatra.
