considerable area during the past year. It is known that man- 

 goes were shipped to the Island of Maui last year from the in- 

 fested district (before the presence of the weevil had been dis- 

 covered), and it is probable that the weevil has been carried to 

 that island. To date the reported distribution is confined to the 

 Island of Oahu and extends from Xuuanu Valley. Honolulu, in 

 the Ewa direction to Pearl City. 



the weevil axd its life-cycle (See Plate I. A.) 



As a beetle, the mango weevil has a thick pair of wing-covers 

 which, when folded together at rest, give the body the appear- 

 ance of a shell. The wing-covers are much rounded and ex- 

 tremely hard. As a weevil, the head is prolonged in front into 

 a beak or rostrum, bearing the antennae on its sides and the 

 modified mouth-parts at the extreme end. The mouth-parts are 

 formed for gnawing. In the mango weevil, the beak is short 

 and thick and when at rest is turned back beneath the thorax in a 

 groove terminating between the first pair of legs. The adult 

 weevil varied from i 4 of an inch to 5 16 of an inch in length 

 in the specimens measured. "When newly developed, the adult 

 is a whitish pink in color, but soon changes to a dark brown 

 with yellowish markings. 



The beetle feigns death on being disturbed and drops to the 

 ground with the head drawn well under the thorax and the legs 

 folded beneath the body. Its protective resemblance to coarse 

 earth and debris is particularly noticeable. Nothing has been 

 observed in regard to the food habits of the adult. 



The eggs of the mango weevil were found on mangoes from 

 one-half to three-fourths fully grown, situated alongside a slight 

 incision on the rind. The writer has not observed egg-laying or 

 carefully noted the habits of the weevil as regards oviposition, but 

 is inclined to think that the eggs in the instances seen were prob- 

 ably placed within the incision or cavity and later forced out by 

 the exudation of juice, an amount of which in a dried condition 

 enveloped them. 



The larvae in appearance are. generally speaking, like the sugar-
