AN EXPEDITION TO MOUNT KINA BALU. 
form has, however, except for its luminosity and absence of 
wings, little resemblance to the S. American form, and rather 
recalls an Oiiisci/s in its oval shape and uniform segments, al- 
thougdi its body is more elongate. Its head is small and black. 
Mouth appendages normal ; mandibles long, thin, curved, and 
crossing each other in repose. Antennm with four joints each : 
length of first joint, 2 mm., of second 1 mm., of third 4 mm., of 
fourth 1 mm ; first and second joints and proximal half of third 
joint white, distal half of third joint black, fourth joint yellow and 
covered with setae. Eyes small (0-5 imn. diameter), placed behind 
the base of the antenme. The body is much depressed, with little 
difference between the segments of the thorax and abdomen. 
The larger of the two Si^»cimens captured is GO min. in length 
(prothorax 12, mesothorax 7, metathorax 6, abdomen 3o mm.), 
18 mm. in greatest width (metathorax), 7 mm. in greatest thick- 
ness. The terga are slightly arched and entirely smooth ; colour 
black, wdth a narrow white marginal border on the prothorax 
wOiich is continued and wddens posteriorly until, in the eighth 
abdominal segment, only a small black patch is left in the centre 
of its posterior margin. The last segment is small, 4 mm. across, 
and entirely black. The legs are black, wdth the exception of 
the tibim ; the first seven and the ninth sternum, the chitinous 
patches around the thoracic (prothorax and mesothorax) spiracles 
and those around the first seven abdominal ones are also black ; 
the rest is white, viz., the eighth sternum, except for a black cross, 
the membranous portions between the sterna, the tibite, and 
especially also the circular area around the eighth abdominal 
spiracle. In this oval white patch, measuring 3-5 by 2 mm., the 
luminous organ is situated, and the light given off by it is of an 
extraordinary brilliancy. I had one of these larva? alive for 
nearly a week, and enclosed in a glass-tube, it served me as a 
night light during the long sleepless nights on Kina Balu. 
Dr. Sharp to whom I submitted this species for identification, 
marked it ‘ Larva of Lampi/rules, unknown,’ but on account of its 
luminosity I venture to regard it as an adult female, similar to the 
8. American form mentioned above. The absence of sufficient, 
material for dissection, however, makes a final decision impossible 
The following is a list of the Orthoptera, Coleoptera and 
Rhynchota as identified by Dr. Bharp.
