80 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 Oniscus in its oval shape and uniform segments, al- 

 though its body is more elongate. Its head is small and black. 

 Mouth appendages normal ; mandibles long, thin, curved, and 

 crossing each other in repose. Antennae 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 mm. diameter), placed behind 

 the base of the antennae. The body is much depressed, with little 

 difference between the segments of the thorax and abdomen. 

 The larger of the two specimens captured is 60 mm. in length 

 (prothorax 12, mesothorax 7, metathorax 6, abdomen 33 mm.), 

 18 mm. in greatest width (metathorax), 7 mm. in greatest thick- 

 ness. The terga are slightly arched and entirely smooth ; colour 

 black, with a narrow white marginal border on the prothorax 

 which is continued and widens 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, with the exception of 

 the tibiae ; 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 tibiae, 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 larvae 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 L amp y rides, unknown,' but on account of its 

 luminosity I venture to regard it as an adult female, similar to the 

 S. 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. Sharp.
