APPENDIX. 67 



Pselaphus palpiger, n. sp. 



P. gracilis, rufo-castaneus, nitidissimus, parcissime fulvo-pubescens, 

 impunctatus ; capite prothoraceque angustissimis, ovalibus ; oculis 

 minutissimis, demissis, subobsoletis (e lentibus perpaucis conipo- 

 sitis) ; elytris triangularibus, brevissimis, singulis linea suturali 

 Integra et altera sulciformi basali abbreviate, instructis ; palporum 

 maxillarium articulo ultimo longissimo, subflexuoso, breviter pu- 

 bescente ; tarsorum art 2 do sat grosse clavato. Long. corp. lin. 1. 



Habitat in Gomera, a DD. Crotch parce collectus. 



In the immensely elongated siibflexuose last joint of its maxillary 

 palpi, its extremely narrow head and nearly obsolete eyes, the curious 

 little Pselaphid from which the above diagnosis has been drawn out, 

 and which practically must be well-nigh blind, might almost claim a 

 distinct genus for its reception ; yet in size, colour, clothing, surface, 

 and general contour it so much resembles the European P. Heisii 

 that before careful examination it might literally be mistaken for 

 that insect. Apart, however, from the enormously developed, some- 

 what ensiform apex of its palpi, its rudimentary eyes, and the greatly 

 narrowed anterior segments of its body, it may be known by its elytra 

 being likewise narrower, as well as much shorter and with the line 

 down the disk of each obsolete posteriorly, by its antennae being a 

 little paler and rather more abbreviated, and by its feet having their 

 second joint a little thicker and more clavate. 



Several specimens of the P. palpiger were taken by the Messrs. 

 Crotch in Gomera, during their late Canarian campaign.
