Group Pselaphidae. 

 Patrkus, gen. nov. 



Bodtj elongate. Antcniial tubercles small. Hind body 

 elongate, basal three segments large, nearly ecjual, with deep 

 sutures. Melastertnim elongate. Prosternum witliout visible 

 eariiui. Intermediate //T/Zcp remarkably short, curvate; ])asal 

 joints of intermediate tarsi enormously developed, second 

 smaller than tirst, the third elongate and slender ; with one 

 claw. 



This genus should be plaocd near Exeirarthra, the an- 

 tenuic, however, instead of being like those of Sof/ola, more 

 nearly resemble those of Zelundiits. From the latter it is 

 distinguished by the more slender form, impuuctate surface, 

 much smaller and more anteriorly narrowed head, oviform 

 thorax, shorter antennae, and slender legs. From all the 

 other Euplectini known to me it may be easily recognized 

 by the strongly developed basal joints of the middle tai'si, 

 which indeed somcw hat resemble the male feet of an Aphilon, 

 one of the Phytophaga, but with the basal joints homo- 

 geneous in place of being distinctly- separated. The tarsal 

 structure of Eueirarthra, another curious form of this group, 

 is materially difterent, the penultimate joint of the anterior 

 tarsi being distinctly lobate, whilst the terminal is provided 

 with two claws. 



Patreus Letcisi, sp. n. 



Elongate, nitid, castanco-rufons ; legs, antennae, and palpi 

 yellow ; sparingly clothed with long, slender, greyish 

 pubescence. 



llenil small, the vertex deej)ly and unevenly excavate. 

 Antenna; pubescent, basal joint large, 2nd shorter and not 

 quite as stout, joints 3-8 small and bead-like, 9tli larger 

 than the preceding one, but not so broad as the lOth, II tU
