In his two papers of 1916 Fahrenholz raises his variety to the rank of sub- 
• species, terming it P. capitis angustus in the first paper (vn. 1916, p. 270), and 
P. corporis angustus in the second (x. 1916, p. 88, corporis being obviously 
printed in error for capitis). To the earlier description he adds that angustus 
scarcely attains the size of European capitis #, but is much narrower , appearing 
much slenderer#. Claw I is very long and dentate#. “Allgemeinfarbung 
hellgelb#; Chitinisierung gut entwickelt; Randplatten des Abdomens tief- 
schwarz#. Querplatten des Abdomens beim $ sehr deutlich%\ desgleichen die 
Genitalplatte#. Sternum vorhanden#, aber Rander undeutlichA 
Fahrenholz (1917, p. 2, reprint) refers to specimens of angustus at the 
Hamburg Museum. 
Pediculus capitis macuiatus (Fahrenholz 1915) Fahrenholz 1916. 
A sub-species. 
Synonym: 
“Pediculus capitis de Geer var. macuiatus n.var.” Fahrenholz 1915, 
p. 598, PI. XXI, fig. 2 (photo of ?), fig. 3 (photo of $), text-figs. 3, 4 (d venter, 
$ sternum). 
This form, emanating from Cameroon negroes, is described from balsam- 
mounted specimens (d $). The lice have a light yellow colour# in which they 
differ at once from lice on Japanese. Pleurae broader than in Japanese lice#. 
S with dorsal bands dark brown#, sternum#, genital plate# and ventral 
band clearly defined#, four holes in the sternum bearing hairs#. $ with two 
brown spots dorsally on last abdominal segment# (as in Haematopinus)\ 
sternum clearly defined#, with two holes anteriorly bearing hairs#. 
In his papers of vn. 1916, p. 271; x. 1916, p. 88, and 1917, p. 2 (reprint), 
he raises the variety to the rank of a sub-species, stating (x. 1916, p. 88) that 
the general form is distinctive, being shorter than “P. capitis angustus ” 
(vide supra ) •; whilst the $ is “broader than European capitis # A “ Gut unter- 
schieden durch hellbraune Grundfarbung# 1 . Chitinisierung ausserst kraftig; 
vordere Randplatten des Abdomens verbreitert •. Querplatten auf dem Abdomen 
des dunkel braun#, desgleichen die Genitalplatte# und mediane Ventral- 
platte des II Segments (our ventral band)#. Sternum deutlich gerandet#. Lebt 
auf Negern (Kamerun); eine etwas abweichende Form auf Hottentoten 2 .” 
“Pediculus capitis capitis de Geer” of Fahrenholz 1917. 
A sub-species. 
Term applied by Fahrenholz (1917, p. 2, reprint) to specimens in the 
Hamburg Museum identified by Fahrenholz as such. 
1 Light yellow in his first description, light brown in his second. 
2 Another Fahrenholz variety which no doubt will presently be described.
