This is the first lime that any species of this genus has been found 

 in the United States. Il is easily distinguished from ^S". rnexicamis 

 (Saussure), by having a few scales on posterior dorsal plates. 

 The collection contains two specimens of this species. 



17. Polyxenus fasciculatus Sny. 



Common at Little Rock, five were obtained at Antoine and one at 

 Ultima Thule. 



18. Pauropus lubbockii Packard. 



A few specimens were obtained at Little Rock. 



19. Linotaenia bothriopa (Wood). 



I have received one specimen that was collected near Little Rock by 

 Mr. Hutcherson.

 I refer this species provisionally to Z. robusta (Meinert), although it 

 differs from Meinert's description by rather unimportant characters. I 

 have also seen specimens of this species from Tennessee. 



21. Linotaenia branneri sp. nov. 



Frontal plate present. Fulvous, head and antennae dark. Robust, strongly at- 

 tenuated anteriorly, less posteriorly ; moderately smooth, sparsely pilose. Prehensorial
