tera of the West Indies, that on the Orthoptera of Cuba by Ignacio 

 Bolivar with 145 species, are the only important papers we have. 



It may be inferred from these facts, however, that each of the 

 other islands of the group will furnish undescribed genera and species 

 of closely related forms — those that have become so differentiated by 

 long isolation under changed environment. Why not institute a 

 systematic campaign for learning what all of these nearby islands con- 

 tain in the way of insect life? This should by rights be done by 

 American entomologists. 



The arrangement of the non saltatorial families in this paper is 

 after Kirby's Synonymic Catalogue of the Orthoptera, Vol. I. 



Order DERMAPTERA. 

 Although the members of this order are not Orthoptera as now 

 recognized, they have been so long considered as such that it is 

 thought best to include them here. At least five species are at hand, 

 four of which seem to be new. They are the following : 



1. Labia trinitatis, new species. 



A small, dark brown insect with a plain black head, pronotum, tegmina and 

 wing sheaths, in which the disk of the abdomen above the forceps are reddish ma- 

 hogany-colored. Hody provided with a few stout bristles at sides of abdominal 

 segments. Antennae 10-13 jointed, dusky at base but becoming paler apically — 

 the last two or three being obscure testaceous. Legs of normal length, the femora 

 moderately stout ; the latter dull black except apically where they are testaceous, the 

 tibia?, except on basal half where they are infuscated and tarsi pale testaceous. Head 

 wider than the pronotum, the clypeus, labium and other mouthparts dirty testaceous. 

 Pronotum about as long as wide, the sides parallel, hind margin broadly rounded, the 

 front edge a little angulate, the shoulders each provided with a conspicuous anteriorly 

 projecting bristle ; the disk forward moderately convex and showing a well-defined 

 longitudinal sulcus. Tegmina a little more than twice as long as broad, their apices 

 gently obliquely truncate, the surface smooth and shining. Wing-sheaths fully de- 

 veloped. Abdomen broadened in the middle, segments 2 and 3 showing slight traces 

 of lateral folds ; the last dorsal segment of male abdomen a little narrowed behind, 

 its posterior edge straight and possessing a slight protuberance above the base of each 

 prong of the forceps. The latter short, moderately robust at base where they are 

 widely separated, their inner edge provided with a carina which ends in a small 

 tooth, parallel for about one third their length, beyond this tooth tapering and evenly 

 curved so that the tips cross on outer fourth. The arms of the female forceps also 

 quite robust at base, but tapering quite rapidly, the inner edges touching and the 

 apices gently crossing.
