Note on the Eggs of Araeocerus Fasciculatus De G. 

 (Anthribidae, Coleoptera). 



BY O. H. SWEZEY. 



In examining- some koa pods collected on Sugar Loaf Hill, 

 June 23, 1919, I found several clusters of white, hatched eggs 

 inside the pods where the larvae of Cryptophlebia illepida (But- 

 ler) had eaten out the seeds and had made exit holes thru the 

 side of the pod. At the time I could not make a satisfactory 

 determination of these eggs. 



On November 9 of the same year, I collected some more 

 koa pods in the south end of the Waianae Mountains. On ex- 

 amining these, many more of the same eggs were found, mostly 

 hatched, but a few that were unhatched, and these hatched a 

 few days later. In the same batch of koa pods were also many 

 €:gg clusters of Pantoniorns fnlleri (Horn), some hatched and 

 others unhatched. As the unknown eggs were somewhat simi- 

 lar and placed in similar places, and as the young larvae also 

 resembled those of P. fiillcri (except that they had legs), and 

 as there is no other related beetle known here of which these 

 could have been the eggs, I feel certain that they belong to 

 Araeocerus fascicnlaUis. 



I have looked up many references to this beetle in American 

 entomological literature, and also from other parts of the world, 

 but I could find no mention or description of the eggs, from 

 which one could infer that the eggs were not known. Hence, 

 I herewith give a description of the eggs. 



Before hatching the eggs were yellowish ; the empty egg- 

 shells are pure white. The surface is completely ' covered with 

 longitudinal rows of pits like the surface of a thimble ; short 

 cylindrical, with rounded ends about 0.8 mm. long and about 

 0.4 mm. in width. They were deposited in rather loose masses 

 of 40 to 60 eggs, yet adhering together, tho not firmly cemented 

 together as is the case with those of P. fnlleri. They had
