NEW MALLOPIIAGA. 93 



\^ir. domeftticiifi Kelloy;g and Cliapinan; one male 

 from the 15ain Swallow, Chetidon erythrogastra (Cali- 

 fornia); body, length 1.54 nnu., width .11 luui: head, 

 length .37 mm., width .31 mm.; thus being of about 

 same size as the species type, and twice as long as 

 Nitzsch's (jracUifi, the common Xirmus of the Euro- 

 pean swallows. Characters of species with differences as 

 noted above. Osborn (Insects Affecting Domestic Ani- 

 mals, 189G, p. 22.")) refers a specimen from the Purple 

 Martin, Proyne subis (Ames, Iowa), to gracilis. He 

 does not give the measurements of his specimen.

Specimens from two Cedar AV'axwings, Ampelis cedro- 

 rum (Palo Alto, California). Osborn's specimens wei'e 

 from same host (Ames, Iowa). Giebel's types are from 

 same host. 



Lipeurus. 



Lipeurus laculatus n. sp. (Plate \'II, llg. 1). 



Four specimens collected of this strikingly marked 

 Lipeurus; an adult male and an immature individual 

 from a Pomarine Jaeger, Sfercorarius pornarinus, and an 

 adult male and an immature from a Pink-footed Shear- 

 water, Puifinus creafopus (Bay of Monterey, Calif.) We 

 believe that the specimens from the Shearwaters are 

 stragglers from the Jaeger. (We have examined so many 

 Shearwaters that, were the species a regular parasite of 

 Pu^lnus, we should have taken other examples.) 

 One other individual of Stereorarius pornarinus was
