J XIHRXAL PARASITES OF BIRDS. 279 



Homoptera, represented by the pear psylla and leaf -hoppers, 

 were found in robin-', catbirds', and song sparrows' nests. They 

 were adults and were using the nests for hibernation purposes. 



It is not at all uncommon to find moths in connection with 

 bird nests. The Tineids, to which our common clothes moth 

 belongs, are found in nests of the robin, crow, house sparrow, 

 redstart, and chipping sparrow. Larva? pass the winter in pupal 

 cases made of the grasses of the nest and resemble caddis-fly 

 cases. Adah- emerge in May when there are fresh nests in 

 which they lay their eggs, according to the statement of one 

 Kuropean worker. The adults were identified by \Y. T. M. 

 Forbes as Tinea carnaridla. Several adults of Carnarsia 

 nhuiarrosorella emerged from robins' nests in the early part of 

 June. As the larva? feed on shade trees, they probably use the 

 nest as a place to hibernate. 



Of Diptera or Hies there were more B] ;''iind than of any 



other opler of insects. Several of them pa.-- through their 

 complete life cycle in the nests. 



.Uiopc flaviceps, a small fly belonging to the Family Sapro- 

 m\/i.Le, is encountered frequently and in lar^r number- in the 

 t thr roliin, woodtlmish, redstart, son;.; SpaiTOM . vldlinch, 

 .atbn.l. n-'l r\i<l vireo and chipping sparrou . Numerous small 

 \\hite larvae and flat yellow pupa? are found in tin- Lot torn of 

 ne.-t- in the fall, \\intcr, and spring month- Thr larva? feed 

 e\rlu-i\ elv on tin- debris and seeds they find in the ne-ts. Adults 

 (.in. :ly in May. It would seem that the : : birds are 



i lu- natural habitat of this species but the fa. t ha- not been noted 

 before. 



Four of Anthomyidae were found. Larvae and pupae o! 



AtitJioniyiii f>lnvinli\ \\ere found in nests of the robin, bluebird and 

 rhippii ni'u. Adults emerged from Mar-h to May. 



Larvae "t I-'iinniti <anicnlaris were found in the ne-t- of robins, 

 bluebirds ami Ixui-e -parrows. Adults of this speues i nu-rged in 

 May. Hydrotaa nidicola is a new (mami-cripi -peries described 

 1>\ J. k. Malloch. Pupae were found in robins' nest^. ami adults 

 emerged in the latter part of April, llyicmyia spizelln is also a 

 new species to be published by 11. C. Huckett. The flies emerged 

 from robin and chipping sparrow neMs in March.
