is not known where it has come from, nor how long it has been 

 established here. It may not become of any economic impor- 

 tance, as it is the habit of the members of this family to store 

 their nests wdth spiders, making burrows in the ground for this 

 purpose. They are not likely to cause much more inroads on the 

 abundance of spiders here than is already done by Sceliphron 

 and Pi SOU: 



liippohoscid. 



In October, also, two specimen's of a Hippoboscid were ob- 

 tained by a Honolulu pigeon fancier, from some of his flock, 

 and forwarded to me via Bishop Museum. There are three 

 species of these insects present in the islands inhabiting such 

 birds as the owl and some of the native birds. Our present 

 species is different from' any of these, and differs also from any 

 common to fowls in the United States. It yet remains to be 

 determined. It is not knoAvn at present how prevalent it is in 

 Honolulu, nor how injurious it may be. 



Menihracid. 



ISTovember 24 I captured two specimens of a j\Iembracid of 

 the genus Tvicentrus in the lower part of the Tantalus Eucalyp- 

 tus Forest. It comes very near to Tricentrus alhomaculatus 

 Dist., which occurs in India. Our specimens may be an Oriental 

 or Australian species, but it is yet to be determined with cer- 

 tainty. The family Membraeidae is not represented in the 

 native fauna of the Hawaiian Islands, and no introduced forms 

 are known besides this, except that Dr. Perkins reported a year 

 or two ago finding a specimen, but of what genus I know not, 

 nor whether it might be the same species that I have now col- 

 lected. 



I present these captures at the present time that records may 

 be made of their first notice here. 



In the discussion that follow^ed, Mr. Giffard washed to record 

 that in the beginning of November he saw one or two specimens 

 of the Pompilus in N'uuanu Valley on stone walls, and last Smi- 

 day on Tantalus at an elevation of 1500 feet he caught another 

 running on a bank.
