NOTES AND EXHIBITIONS. 



ScypopJiorus sp. — Mr. Muir exhibited a large black weevil 

 captured December 17th, 1918, while crawling on a basement 

 window of the Sugar Planters' Experiment Station. It was 

 found to be a species near to ^S'. acupunctaius, of which there 

 are specimens in the Harford & Baron collection of American 

 Coleoptera ov;ned by Mr. W. M. Giffard. In regard to the 

 habits of the weevils of this genus, one is known to live at the 

 base of the yucca plant and another is injurious to sisal in 

 Yucatan. It is the first record of the finding of anything of 

 the kind here, and quite unexplainable how this single speci- 

 men could have made its arrival here. 



Trionymus insularis and Odonaspis ruthae. — -Mr. Ehrhorn 

 recorded the finding of these two scales on Eragrostls from 

 Koko Head, handed him by Mr. W. M. Giffard, December 16, 

 1918. He mentioned Pseudococcus eragrostidis as a third 

 species known to occur on this grass. 



Rhyncophorous larvae. — Mr. Ehrhorn exhibited a vial con- 

 taining 122 larvae of a rhyncophorous beetle, found in (piar- 

 antine inspection work in soil at the base of a Thuya plant 

 from Japan. 



Slnoxylon conigeriDn. — Mr. Swezey exhibited pieces of 

 branches of the algaroba tree showing the work of the adults 

 of this beetle. The specimens of wood were taken from a 

 fallen tree that had l:)een down about three weeks. In each 

 instance a beetle had burrowed into the branch and cut away 

 so much that it nearly severed the branch, very much as does 

 the w'ell-known tree-pruner in oak and hickory trees of Amer- 

 ica, so that they broke off very readily. The branches were 

 one inch to an inch and a half in diameter. 



Nesotocus giffardl. — j\[r. Swezey exhibited pieces of 

 l)ranches of the Cheirodendron tree showing the characteristic 

 pupal cells of this large weevil. They were collected in the 

 forest on the ridge at Ivuliouou, Dec. 22nd. Xo beetles were
