Phylloma labrosum, sp. 1. 
Oblongum, subdepressum, nigrum, nitidum ; fronte obscure bistriata, 
labro elongato, mandibulis antice depressis; elytris striis, 1 late 
interrupta, appendiculata, 2 brevi, obsolete appendiculata, 3 brevis- 
sima; pygidio transversim punctulato ; tibiis anticis 4-dentatis. 
L. 94 mill. (absque mandibulis). 
Oblong, rather depressed, black and shining; the head, 
surface uneven, impressed anteriorly, forehead with two short 
transverse lines, Jabrum large and bilobed, lobes somewhat 
oblique, mandibles very robust at their bases and anteriorly 
depressed from the middle, each with an inner well-marked 
tooth, tips acuminate; the thorax transverse, lateral stria fine 
and lightly impressed, ceasing at the anterior angle; the 
elytra, subhumeral sulcus shallow and abbreviated before and 
behind, at the shoulder close to the base is a very short 
oblique line pointed towards the first stria, the first stria is 
well-marked at the base, interrupted in the middle, the apical 
portion is lightly impressed and there is an indication of an 
appendage to the third stria, which is extremely short; the 
propygidium is sparsely punctulate on its outer border and 
there are two shallow impressions posteriorly ; the pygidium 
is smooth at the apex and also more narrowly along the base, 
leaving a transverse space somewhat closely punctured; the 
prosternum is rather wide at the base, but not distinctly 
angulate, and the anterior part of the keel is depressed ; the 
mesosternum is widely emarginate; the anterior tibie are 
4-dentate. 
The form of the mandibles and the size of the labrum serve 
as good specific characters to distinguish this insect.
