396 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxm. 



All the species considered valid have been included in this key; 

 the following have been omitted for the reasons stated: P. alaius 

 described by Johnston in 1836 has been proved a synonym for Ech- 

 throgaleus coleoptratus. P. hoscii Leach, 1816, becomes a synonym 

 of P. hicolor of the same author and date. Dana's P. concinnus 

 can not be distinguished, in the description he has given of it, from 

 P. cranchii, and may therefore be left as a synonym of the latter until 

 further described. The same may also be said of Milne Edwards' 

 P. dentatus, which becomes another synon3rm of P. cranchii. The 

 P.Jissifrons of this latter author is probably a synonym of P. hicolor. 

 P. lamnse, Johnston, 1835, is a synonym of Dinematura producta. 



No figures of P. lividus Frey and Leuckart, 1847, have ever been 

 published, and it is impossible to distinguish it from P. hicolor by the 

 author's description. Of Hesse's P. musteli-lxvis, 1883, neither the 

 description nor the figures given will warrant its inclusion in the 

 genus Pandarus. The description says nothing whatever about the 

 thoracic legs except that they are made up of a large femur, termi- 

 nated by flat laminae, armed with rigid plumose setae. In the three 

 figures given, two of which are the dorsal and ventral surface of the 

 same specimen, there are so many discrepancies in essential details, 

 even between the right and left sides of the same figure, that no 

 definite information can be obtained. As figured and described, not 

 one of the specimens can belong to the genus Pandarus. 



P. pallidus Milne Edwards, 1840, is a synonym of P. crancJiii, and 

 P. vulgaris of the same author is probably a synonym of this species 

 also. Hesse's unicolor has been left in the key, but it may be noted 

 that he has made many wretched errors in describing it. He had 

 what he called an adult female, a young female, and a young male; 

 Plate VI on which the figures of this species are given evidently suf- 

 fered a bad mixup in the arrangement of the numbers assigned to 

 the several figures. The present author secured a reprint of the 

 original paper, bearing Hesse's autograph, in which there has been 

 a thorough correction (in ink) of the references and a rearrangement 

 of the numbers. It is impossible to tell whether this was done by 

 Hesse himself or by another, but the new numbers fit the description 

 much better than those originally published. 



And yet there are still so many discrepancies between text and 

 figures that the species must be left on the doubtful list until further 

 substantiated. And finally Brady presented in 1883 what he clairjied 

 as a new species, calling it P. zygsense since it was found on Zyg^na 

 malleus near the Cape Verde Islands. After careful examination 

 this proves to be a synonym of P. satyrus Dana (see p. 416).
