ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS OF 



THE GLOBE 



Bird Lice (Mallophaga) Attaching Themselves to Bird Flies 

 (Dip., Hippoboscidae). 



Finding two instances of this phenomenon led the writer to look up 

 previous records. In this he has had the help of Dr. Joseph Becquaert. 

 The latter and Mr. J. R. Malloch named the bird flies concerned in the 

 present cases and Mr. E. A. Chapin the bird lice. In each of the two 

 instances the fly was Ornithoinyia ai'icularia L. as our slightly differ- 

 entiated form is still known, and it happened also that the louse in each 

 case was the same, namely, Degccriclla rotundata Osborn. One collec- 

 tion was made at the mouth of the Macfarlane River, Lake Athabaska, 

 Saskatchewan, Aug. 11, 1920, by Francis Harper, from what bird is not 

 stated, and the other from a western crow (Corvus brachyrhynchos 

 hcspcris} taken near Ontario, Oregon, Sept. 30, 1920, by E. R. Kalm- 

 oach. In both cases the mallophagan had attached itself to the hip- 

 poboscid by biting the mandibles into the upper surface of the abdomen 

 near the hind margin.

Dr. Sharp exhibited a specimen of O. aricnlarc L., collected at Dart- 

 ford, England, "to which were firmly adhering apparently by their man- 

 dibles several specimens of a mallophagous insect."

The extent to which the H'ppoboscid genus Ornithomyia figures in tin- 

 above records is rather surprising, certainly more than would be expect- 

 ed considering the abundance of flies of this genus relative to others in 

 the family. W. L. McAiEE, U. S. Biological Survey, Washington, D. C.
