ENTOMOLOGICAL NOTES. 



Mr. Peinberton exhibited a microscope slide showing stridii- 

 lating organ of the ant, Pheidole megacephala. It is an oval 

 striated area on the anterior portion of the third dorsal segment 

 of the abdomen, which is rubbed by hairs on the second segment 

 of the petiole when the abdomen is raised and lowered quickly. 

 The stridulation is not audible in the worker and only with dif- 

 ficulty in the female. 



Mr. Bridwell exhibited a nest of Trypoxylon bi color, and 

 a box of Xorth American Trypoxylonidae. 



A Note on "Nesotocus giffardi" Perkins. 



BY OTTO H. SWEZEY. 



Seven males and six females of this large endemic Curculi- 

 onid were taken by Mr. Montague Cooke from a Cheirodendron 

 tree along the Castle Trail on the side of Kaumuahona not far 

 above the Rest House, at 7 a. m., January 4th, 1914. More 

 specimens were present but escaped being captured. 



Very few specimens of this species have previously been ob- 

 tained. I collected a single male in flight on the top of Ka- 

 umuahona, July 12th, 1908. There is but one specimen in the 

 Bishop Museum, collected by Dr. Perkins on Tantalus. 



The species is described by Dr. Perkins in Fauna Hawaii- 

 ensis. III, Part VI, p. 654, 1910, the male only being known. 



Three other species of this endemic genus are known: one 

 on Kauai, one on Maui and one on Maui and Hawaii, Dr. Per- 

 kins says that all of them live in the wood of the Cheirodendron 

 tree.
