As the season advances, such fare is exchanged for diptera 

 and leptdoptera. In^addrtion to the foregoing insects which 

 are fed to the young, Asilits sericeus, A. ccstuans. Jtowbv 

 lius ccqnalis, among diptera, are greedily eaten ; together 

 with the additional lepidopterous insects of Chcerodes trans- 

 versata, Acronycta obllnita^Orgya leucostigma* Eudryas 

 grata, and others in the adult stage. The species is also 

 somewhat frugivorous, subsisting upon the fruits of Fra- 

 garia Virghiiana, I\ubns ~cillosus* Kibes rnbntiu* Priurnt 

 scrotina, and, late in the season, the berries of Junipcrus 

 Virginiana and Lonicera periclymenum. Wilson de- 

 scribes them as feeding upon similar berries in the lo\v 

 swampy forests of the Carol inas, during the month of Feb- 

 ruary. In the spring of 1868, Mr. Maynard found some 

 Individuals with stomachs filled with hawthorn berries. 



The eggs are round-oval in configuration, acuminate at 

 one extremity, and larger and obtuse at the other. The 

 ground-color is mainly a pure white, and is mostly devoid of 

 spots ; although specimens are occasionally found with red- 

 dish-brown dots at the larger extremity. They measure .Si 

 of inch in length, and .60 in width.

The Olive-sided Flycatcher is a comparatively rare species. 

 It was first obtained by Richardson on the Saskatchewan and 

 described by Swainson. Only a single individual was pro- 

 cured. The next individual appears to haye been met in the
