but there seems to be no doubt as to the relationship of the two, 

 in the light of future observations. Because of the danger of 

 introducing a most serious pest, no living examples were 

 brought out. 



The larva forms a case for pupation, composed of a brownish 

 material, probably largely excrementitious. This case lies 

 within the bean pod and the adult emerges through an irregular 

 opening which is broken out at or near the end of the cell. 

 Several pods which were opened for examination showed the 

 newly disclosed adult weevils, feeding larvae and other larvae 

 in their cells. Sometimes as many as three grubs had attacked 

 a single bean. Occasionally one seed in a pod would be sound 

 while all of the rest would be damaged. 



In order to estimate the percentage of damage, a lot of pods 

 were picked and opened. Further, a number were examined 

 for the blotches but not gathered. This estimate indicates 

 that in the plot most carefully studied the injury runs about 

 80 per cent. Badly attacked seed did not mature in the pod 

 but shrivelled and became distorted. ' 



From my observations, it appears that the adults emerge 

 from the pupa case into the lumen of the pod and probably 

 depend upon the pod splitting to effect their escape. If this 

 be true, it follows that the danger of introduction of this pest 

 into the United States lies mostly in permitting shipment of 

 green beans, i. e., snap beans and fresh shell beans. It is doubt- 

 ful if there is much danger from dried beans of good grade, 

 although thev can not be considered entirelv safe.

In my opinion, shipment of beans in the pod, whether green 

 or ripe, from Mexico to the United States, would be dangerous 

 and might easily result in the introduction of another bean pest 

 of first rate importance. I consider that on the plateau, near 

 Mexico City at least, this Apion is a worse menace than Epi- 

 lachna. Since observations in Mexico show it to be coincident 

 in bean fields with Epilachna, it is probable that the same habit 

 would obtain in the United States, and I consider it likely that 

 in case of introduction it would do as great damage in this' 

 country as in its native home.

Wesmael's description 1 was based on an insect having 17 

 joints in the antennae in the female and 20 to 26 joints in the 

 male.
