Different Species Of “Trilobite-Larv^e” Found In Borneo. 
The following types of “trilobite-larvse” are known to me 
from Borneo: 
No. 1. (Plate III fig. 1) 
$ : Larva : A very large remarkable form, shining black 
with a row of four bright sealing-wax red 'tubercles at the hind 
margin of the thoracic segments and two rows of median sealing 
wax red tubercles on the hind margin of the first eight abdominal 
segments. Also the margins of the thoracic segments of the ab- 
dominal segments are of the same bright color. The anterior 
prothoracic margins show two small tubercles or processes just 
behind the head; the prothorax is of a triangular shape, with 
rounded, obtuse hind angles, the sides of the meso- and meta- 
thorax are more parallel; all three segments are distinctly punc- 
tured and with a slight median, smoother elevation. 
Measurements : Greatest length 92 mm., greatest width 20 
mm. 
Locality : Mt. Murad, N. Sarawak. 
Altitude 4000-7000 feet. 
Adult $ : In everything similar to the above described 
larva, but with a sexual opening, surrounded by genital valves 
on the eighth sternite. Color yellowish- white. Size slightly 
smaller than the larva, c? unknown! 
No. 2. (Plate III fig. 2) 
$ : larva : Duliticola paradoxa sp. nov. vide description above. 
Adult $ : vide description above. 
No. 3. (Plate III fig. 3) 
Cinnamon colored, with two black shining tubercles on the 
thoracic and the first eight abdominal segments; the abdominal 
lateral processes dark colored. Prothorax more rounded behind 
than in larva No. 1 and the hind angles smaller, metathorax 
with more protruding hind angles. 
Closely related to No. 1 and probably belonging to the 
same genus.
