238 MALLOPHAGA. 



scription it is impossible to be certain that these specimens are not sub- 

 specifically distinct from Xitzsch's specimens. Piaget says (Les Pedi- 

 culines, p. 138), that N. stramineus Denny is a synonym of this form, 

 but from Denny's description and plate (which are fairly good) they 

 seem to me to be distinct." The original description was from speci- 

 mens taken from Picus conns, and it has been recorded on Picus viridis. 

 In this country Osborn has reported a species believed to be candidus 

 from Ceniurus carolinus (L.). 



Nirmus simplex Kellogg. — Two specimens, male and female, from 

 the roljin, Planesficus migratorius (L.). They were first described by 

 Kellogg from the same host, and these specimens agree very well with 

 his description and figure. 



Colpocephalum bicolor Piaget. — A young freshly moulted female 

 taken on the turnstone, Arenaria interpres (L.), probably belongs to 

 this species, since it was first described from the same host. This 

 species is not included in Kellogg's list of North American Mallophaga. 

 Colpocephalum spinulosum obscurum Carriker. — The description 

 of this new subspecies of C. spinvlosum Piaget, as prepared by Mr. 

 Carriker, has been published in the Entomological News (1910.) It is 

 of the same size as C. s. minor Kellogg, but differs from it in the pro- 

 portions of the head, and in a number of details of color pattern. A 

 male and female from the turnstone, Arenaria interpres (L.), were the 

 only specimens obtained. 



Colpocephalum ocularis Carriker. — This easily distinguished new 

 sjDecies has been descril^ed and figured b}' Mr. Carriker in the Ento- 

 mological News (1910). The two most striking features are the pecu- 

 liar V-shaped ocular bands, and the spindle-shaped, constricted abdo- 

 men. A single female was taken on the turnstone, Arenaria interpres 

 (L.). Careful search should be made on other specimens of this bird 

 to find the male belonging to the species. 



Colpocephalum subpustulatum Carriker. — Only one specimen, a 

 female, was found belonging to this new species, which has been de- 

 scribed and figured elsewhere with the other new species by Mr. Carriker 

 (1910). It is distinguished from C. pustulosum Piaget, which species 

 it most nearly resembles, b\' the absence of the conspicuous double row 

 of clear pustules on the abdomen and on the posterior margin of the 

 head; by the absence of long hairs anywhere except on the temples: 

 and by the absence of the fringe of fine hairs at the posterior extremity. 

 It was captured on the belted kingfisher, Ceryle alcyon (L.). Mr. Car- 

 riker states in his notes that this is the "first record for a species of this 

 genus on any member of this family. Osborn has recorded C. pustu- 

 losum Piaget from the kingfisher but it was ])robably a specimen of 

 the present form, as the two have a superficial resemblance." The
