 ColeotichushlacTchymiae F. B. White. (^^*) 



Tkis probably endemic Scutellerine is the handsomest of 

 Hawaiian Insects. It is found principally on koa trees 

 (Acacia koa), on the leaf -like phyllodes on which it lays its 

 eggs. While Oechalia is quiet and a death-feigner, ColeoHchus 

 whirrs off with a tremendous racket and a great speed, when 

 disturbed. It is apparently vegetarian. 



The ova are very different from those of Oechalia, being 

 golden green (yellowish white in alcohol), not appreciably 

 sculptured and without an operculum. They are deposited in 

 batches of about 19, usually 1 in the middle, 6 around that 

 and 12 around these. They are roundly hexagonal. Their 

 height is about 1.155 mill., diameter from side to side 1.15'i 

 mill., from angle to angle 1.442 mill. Beyond a sparse, very 

 minute granulation there is no sculpture visible x. 118. (fig. 2.)

 Mrs. Blackburn and was published as written above.
