196 ENTOMOLOGICAL NEWS. [May, '15 



mangrove swamp, where individuals sprang about with astound- 

 ing rapidity. Several other mangrove swamps about the shores 

 of Biscayne Bay were carefully examined without a trace of 

 the present species being found.

Hygronemobius liura^ new species. 



Type* S ; Tukeit, British Guiana. July 21, 191 1. F. E. 

 Lutz. American Museum of Natural History. 



Size small; form compact. Head with interantennal protuberance 

 very feeble, more so than in H. alleni; maxillary palpi compact, entirely 

 dark. Pronotum much as in alleni. Tegmina reaching base of abdo- 

 men, distal margin strongly truncate and very briefly but strongly de- 

 flexed, veins very weak, cordes and diagonal vein connected at their 

 extremities by a very weak transverse vein, tambourine absent. Wings 

 absent. Caudal face of cephalic tibiae bearing a large elliptical tympa- 

 num, corresponding portion of cephalic face not swollen. Caudal fe- 

 mora as given in generic description; the three spines on each of the 

 dorsal margins are however not literally paired but alternating; distal 

 spurs not as long as in alleni, dorso-internal spur (longest of the five 

 distal spurs) reaching only four-fifths of the distance to the distal ex- 

 tremity of the metatarsus (in alleni this spur equals the metatarsus in 

 length). 



Allotype. Same data as type. 



Agrees with the types except in the following sexual features. Teg- 

 mina greatly aborted, visible portion almost wholly lateral in position 

 (so much so that the tegmina can scarcely be seen from the dorsal as- 

 pect), triangular in outline with angle (disto-lateral in position) 

 broadly rounded. Ovipositor subrect; apex with margins unarmed, 

 dorsal margin very weakly subconcave below line of dorsal margin of 

 shaft, ventral margin very weakly convex from proximal swelling to 

 the very sharp apex. 



Coloration. $ . Very dark brown ; very weakly punctate and 

 mottled with a paler and more reddish shade, this mottling more evi- 

 dent on the caudal femora. Tegmina glossy and piceous ; intermediate 

 channel cream-buff, this marking continued as a rather broad trans- 

 verse band margining the tegmina distad, a spot of the same color at 

 the base of the free margin of the dorsal field. 



6. From XcTa smooth and oipa tail. A substantive alluding to the 

 ovipositor difference between this species and the species of nearest 

 relationship, alleni.
