nests of swallows and martins, where they 

 remain throughout the winter. 



1. Melophagus ovinus, Linn. Sheep Tick. Common 

 amongst the wool of sheep. 



Order VII. APHANIPTERA. 



Of this neglected order, or sub-order, of Diptera, 

 only fourteen species have hitherto been described as 

 British; but on looking over the following pages it 

 will be seen that thirty-eight have been taken in this 

 parish. I have added short descriptions of those not 

 previously described, but refrain from doing more, as 

 it would take up too much room to give long ones ; 

 and besides I hope to write a monograph of them 

 another day. Owing to the diversity of shape I think 

 one or two additional genera might be formed. 



Pulicida. 



1. Pulex irritans, Linn. Common Flea. 



2. P. canis, Curt. On dogs. 



3. P. erinacei, Leach. On hedgehogs. 



4. P. felis, Bouche. On cats. 



5. P. sciurum, Olf. On squirrels. 



6. P. gliris, Dale. On dormice. Piceo-fusca, laevis, 



capite flavo et nitente, pedibus pallidioribus, 

 abdominis lateribus nudis, prothorace nigro- 

 costato, tarsorum articulo primo longissimo.
