APHANIPTERA. 31 



the pro-thorax. Mr. Haliday first discovered the antennae of this 

 species. They are two-jointed, short and flat, the first joint having 

 a bristle near its internal apex, and the other crowned with spines. 



This species is common on the dog and fox, and most other 

 members of the Canidce. 



Piilex gallincB, Bouche. 



Deep black above, testaceous below. Differs from irritans in 

 being smaller, more compact, and in the length of the antennas, 

 which are lanceolate, the last joint being thin. Maxillary palpi 

 slender and filiform. Femora bare ; tibia; and tarsi spinose. 



There is a curious comb-like fringe to the pro-thorax. 



This species is common on the domestic fowl, and especially in 

 the nests. Hundreds may be got by putting the hand in the nest. 

 It is also found on other birds, as the thrush, robin, and in the nests 

 of the blackbird. Mr. Dale believes a species described by West- 

 wood from Ceylon as Sarcopsylliis galiinaceus^ to be identical with 

 the one just described.* 



The larvoe of Gallince are darker than those of the domestic flea, 

 and are found in birds' nests. 



P. gallhiix is also recorded from the nests of the house-martin and 

 from those of the sand-martin, in the cracks in the clay. "Those 

 from the nest of the sand-martin were darker than those from the 

 house-martin, and they may be a distinct species. "t 



We have found P. hinindifiis in the nests of the house-martin, but 

 never Gallince^ although repeated searches have been made. P. 

 hiriaidinis does not seem to be given by Verrall ; it nevertheless 

 seems to be a perfectly distinct species. May not the Galii/ue, 

 recorded above, be the same ? 



Pulex hirundinis, Sam, Curtis, and Walker. 



Differs from Gailincc by being testaceous, and by not being so 

 elongated and having shorter antennoe. There is also a black band 

 on the hinder part of the thorax. 



Abdomen and legs setose. Antennae four-jointed ; the basal joint, 

 having three or four long bristles attached to it, can be entirely 

 withdrawn into the pits. Eyes small and lateral. Maxillary palpi 

 slender, the top segments having a few hairs. Labial palpi setose at 

 the tips. Joints of tarsus gradually decreasing from the first to 

 fourth, the fifth being larger than the fourth, and with more bristles 

 on each side. 



This species may include P. columbce and Friiigillce of Walker,
