402 MR. A. MURRAY’S MONOGRAPH OF THE FAMILY OF NITIDULARIA. 
finely pubescent, testaceous. Head bi-impressed in front; club of antennz a little darker 
than the other joints. Thorax transverse, nearly twice as broad as long, a little narrower 
in front, apex emarginate and bisinuate, sides gently rounded, margins reflexed, most so 
towards the posterior angles; anterior angles rounded, posterior angles slightly obtuse 
and a little raised above the elytra. Scutellum triangular, faintly and sparingly punc- 
tate and pubescent. Elytra not wider than the thorax at the base, widest a little before 
the middle, and immediately behind the widest part sloping somewhat acutely obliquely 
towards the apex, which is considerably narrower than the base ; margined ; apex of each 
elytron obliquely rounded, apical sutural angles as well as exterior angles rounded, finely 
pubescent and punctate, with the apex black, and with an irregular, somewhat zigzag 
black fascia near the middle, reaehing neither to the sides nor the suture, projecting 
backwards near the sides, then forwards and zgain backwards; there is also in some 
specimens a triangular patch pointing backwards within the shoulder. Abdomen pubes- 
cent and very finely punctate. 
From Ceylon, where it was collected.by Mr. Nietner and Count de Motschulsky. 
Mr. Wallace also found specimens in the island of Macassar. 
2. HAPTONCUS CONCOLOR. 
H. tetragono affinis ; parvus, oblongo-ovatus, subdepressus, levissime punctatus, levissime 
pallide pubescens, totus pallide testaceus; thorace marginato et reflexo, prope angulos - 
postieos latiore; elytris postice haud multo attenuatis, apice latis recte truncatis. 
Long. $ la, lat. à lin. 
Habitat in insula Dorey. 
Allied to H. tetragonus. Small, oblong-ovate, subdepressed or only very slightly con- 
vex, very faintly punctate, and with a very slight pale pubescence, entirely pale testa- 
ceous. Head even. Thorax considerably narrower in front than behind, widest just 
before the posterior angles, rounded rapidly to them, and sloping'gently to the front; 
the apex is deeply emarginate and bisinuate; the sides margined and reflexed, more 
widely in front than in the middle, and most so at the posterior angles, which are obtuse 
and project slightly backwards at the point; the anterior angles are rounded ; base trun- 
cate straight, except when it reaches the posterior angles, where it forms a sort of pro- 
jecting tooth. Scutellum transverse, triangular. Elytra somewhat convex, not much 
expanded at the sides, gently rounded; apex not much narrower than the base, truncate 
straight, with the exterior apical angles rounded and the sutural apical angles nearly 
right angles. 
From the island of Dorey, New Guinea. Collected by Mr. Wallace. There is an 
example which has the elytra more expanded, as in H. tetragonus, and the disk more 
convex, with a large and deep depression on each side of the suture near the seutellum. 
It is doubtless merely an immature specimen. There is another individual, from Macassar, 
also collected by Mr. Wallace, which has the posterior angles of the thorax not so pro- 
jecting as in the specimens from Dorey.
