236 A NATURALIST IN BORNEO 



before we can dogmatize. I confess to eating, in a 

 moment of scientific enthusiasm, a few Astatheince, and 

 I found that they had an acid taste reminding me 

 forcibly of unripe gooseberries ; but this experiment 

 does not help us forward very much. I was most 

 interested in comparing collections of Galerucids and 

 Longicorns of the two sub-families noted above ; if I 

 picked out at random a Galerucid of striking colora- 

 tion I could almost invariably match it with a 

 similarly coloured Longicorn. How striking these 

 colour-patterns may be is shown by the following 

 little table, and it must be noted that both Galerucids 

 and Longicorns exhibited these colours : 



1. Bright blue with white antennae. 



2. Yellow with blue band across basal half of elytra. 



3. Dark shining blue, with apical half of elytra 



yellow or red. 



4. Elytra dark shining blue, head and prothorax 



yellow or red. 



5. Fulvous yellow or brown. 



The parallelism may extend to quite minor details ; 

 e.g. the Galerucids Antipha nigra and A. abdominalis 

 are coloured according to type 3, but the former 

 has the abdomen beneath black, the latter yellow. 

 Exactly the same difference distinguishes the two 

 mimics Astathes posticalis and A. flaviventris. 



One of the Saperdinids, Entelopes glauca, is red with 

 black spots, and so looks like a common black-spotted 

 Ladybird. Attention has already been drawn to the 

 species of Xyaste which mimic Lycidce. In the sub- 

 family Phytceciince we find a little chalky-white beetle
