Pediculus and Phthirus 
338 
1668. Redi, PI. XVIII, pidocchio ordinario ( corporis $): also Redi (1671), PI. XVIII, 
Pediculus ordinarius ; interesting early figures. 
— Leeuwenhoek, ed. 1807, PI. XVI, figs. 1-8, figures the head, mouthparts, “sting” 
of claws, empty nits attached to threads of wool. 
— Swammerdam, ed. 1682, PI. VII, illustrates the nit before and after hatching, a 
larva, and apparently a $ (corporis); the 1758 edition has Pis. I and II showing 
mouthparts, gut, $ genitalia, nervous system. Remarkably good, much better 
than the figures of many recent authors. 
1778. deGeer, PI. I, figs. 6-10, copulat.ory apparatus, leg I, head (capitis and corporis). 
1781. Barbut, PI. XVIII (corporis), a very poor figure compared to that of Hooke, the 
tarsi figured with two claws that grasp like pincers. 
1811. Ramdohr, PI. XXV, fig. 4 (corporis), gut, fairly good illustration. 
1829-44. Guerin-Meneville, PI. II, coloured figs. 5, 6, comparing corporis and capitis, 
no text. He demonstrated the essential differences since pointed out by many 
authors, some of whom, even within the last two years, supposed that they were 
contributing something new. 
1855. Leuckart, PI. VII, figs. 1, 2, the egg and its micropyle apparatus. 
1861. Murray, text-figs. 1-3 and 2 plates, mainly illustrating claw structure in lice from 
different parts of the world. 
1864. Schjodte, 2 text-figs., mouthparts protruded. 
1865 a. Landois, Pis. II-IV (corporis), egg, anatomy, genitalia, muscles (also in capitis). 
1865 b. Landois, PI. XXXVIII (capitis), mouthparts, spiracle, etc. 
1869. Melnikow, Pis. VIII-XI (capitis), figs. 22, 23, 30, 31, 37-39, embryology. 
1880. Piaget, PI. L, figs. 2, 3 (capitis, corporis); PI. LI, fig. 4 (“ co?isobrinus”); see note to 
Piaget in Bibliography regarding older authors who illustrate lice. 
1890. Blanchard, figs. 672-679, inaccurate, show the mouthparts in different stages of 
protrusion, etc. (capitis). 
1891. Meinert, PI. I, mouthparts. 
1893. Cholodkowsky, figs. 1-6 (capitis), egg and embryo. 
1904. Enderlein, fig. 2 (corporis), mouthparts; also 1905, figs. 1-5, mouthparts. 
1906. Gross, PI. XXI (capitis), ovaries and egg. 
1906. Pawlowsky, figs. 1-13 (corporis), mouthparts; also 1907, Pis. II-VI, figs. 1-33 
(capitis and corporis), sexual organs. 
1908. Dalla Torre, figs. 1 a, 1 b (capitis), general structure. 
1910. Fahrenholz, Pis. and text-figs, (capitis and “ schdffi”); also 1912, PI. and text-figs 
3-7 (capitis, corporis, and “ schaffi”), chaetotaxy, etc. 
1913. Patton and Cragg, PI. LXVI, figs. 5, 6; PI. LXVII, figs. 1-5; PL LXIX, figs. 1-5; 
PI. LXX, figs. 1-6; PI. LXXI, figs. 1-7; illustrating the adult’s head, external 
anatomy of 1st and 2nd stage larvae, $, egg, internal anatomy, mouthparts, sexual 
organs, etc. (capitis and corporis); all the figures are original and for the most part 
good. 
1913. Martin, figs. 16-17 ( Pediculus), longitudinal section of body showing disposition of 
internal organs; mouthparts, much schematized. 
1913. Castellani and Chalmers, figs. 267-270 (capitis and corporis according to the 
legends but all evidently drawn from shrunken specimens of capitis- type as 
evidenced by short palps and stout legs); drawings by Terzi showing^ and in 
dorsal aspect, being the first figures which show the femoral spur on leg III of $.
