EiisfaJis aciiriis. — ]\Ir. Brvan i>ave notes on the V)ibli<f_L;- 

 rapliy of this tiy, and a general (lisens>ion of its extreme 

 abundance followed. This mnckd»reeding' fly is now cons])icu- 

 ons by its entrance into honses, particularly in the lower Ma- 

 iioa, Punahou and Kalihi districts of Honolulu, and is also 

 foimd abundant on the Ewa Coral Plain. None of the mem- 

 bers had found, its breeding places and none could suggest 

 any type of breeding place which would account for its general 

 abundance. ^Ir. Tiniberlake suggested that on account of its 

 strong powers of flight it might be distributing itself from 

 some centralized breeding places. J\Ir. Bridwell suggested that 

 from the known breeding places of its allies, VoJiircJla obrsa 

 and Erii^falis pinictuJatus, it is probably breeding in the ])ine- 

 apjDle refuse at the canneries in Iwilei and iu the sisal refuse 

 at the sisal mill. 



Xylehorus spp. — Mr. Bridwell exhibited series of both sexes 

 of three species of Scolytidae belonging to or related to Xyle- 

 horus, These are all ambrosia beetles, the bui-rowing being- 

 done by the adult beetles while the larvae feed tmou a fungous 

 growth in the tunnels. One of the sjiecies exhibited was from 

 the wiliwili tree {Evythrlna monospcrma) on the Ewa ("(u-al 

 Plain; another was taken from the branches of Dnicdcna aii- 

 rea in Xuuanu ; and the third was working in oliia ha (Syzy- 

 gium sand ir ice use). Other species are known to attack Jrvfr/r/ 

 koa. Bohea, Straussid. Ferroftetla. and other native trees, and 

 it is ju'obable that when the grou]) is thor(dy collected tliat 

 many s]>ecies will be added to the few wbicli ba\-e been de- 

 scribed. 



Odyiicius psciulorli roriiKs. — ^^r. Ih'idwell exhibited s)ieci- 

 mens of what he considered an imdescribed variety of tliis 

 sjiecies of wasp, recently bred by him from Xuuanu Valley. 

 The female has round red s]iots on the second tergife and
