been critically studied by Dr. J. L. Hancock, who is making a special 

 study of the subfamily. 



47. Tettigidea trinitatis, new species. 



Characterized by its rather slender form, small size, spicate anterior edge and 

 evenly granulate surface of pronotum above, the long wings and pronotal process, and 

 by the pale lower half of body and anterior and middle legs of male. 



Pronotum with the antero-dorsal edge strongly angulate and produced upon the 

 occiput in an acute forward projecting spine that reaches as far as the middle of upper 

 edges of the rather large and prominent eyes. Vertex rather narrow, a little more 

 than half the diameter of one of the eyes, projecting slightly in advance of them. 

 Frontal costa narrow, not prominent, deeply sulcate. Antennae moderately long, 

 pale basally in the males, more or less annulate in the females. Face not greatly 

 oblique. Tegmina narrow, the lower apical edge broadly rounded, the upper apical 

 edge angulate, crossed just before the apex by an oblique narrow pale patch. Hind 

 femora robust in the female, usually provided with a median broad pale band. Gen- 

 eral color varying from pale to obscure brown, the legs and abdomen of the female 

 more or less conspersed and banded with testaceous. Head of male below the base 

 of antennae and eyes uniformly dirty white ; lower lateral edges of pronotum, all of 

 under side, front and middle legs, base of hind femora, tips of hind tibia;, the tarsi 

 and most of abdomen also of this color. 



Length of body, d\ 6-75-7 mm., ?, 9 mm.; of pronotum, d, 

 S mm., ?, 9.5 mm.; of hind femora, cf 1 , 4.60-4.75, ?, 5.5-6 mm. 



Habitat. — 2 ■ and 6 V, Trinidad Island, H. D. Chipman, 

 collector (Coll. L. Bruner). 



48. Tettigidea imperfecta, new species. 



A small dark-colored, slender-bodied insect with greatly abbreviated wings and 

 small narrow apically light blotched tegmina, in which the process of pronotum 

 scarcely reaches the tip of the abdomen. Very finely granulate and without the short 

 lateral longitudinal ridges so commonly met with on the disk of the pronotum in vari- 

 ous species of the genus; median carina prominent throughout, the disk anteriorly 

 gently tectate ; antero-dorsal edge decidedly angulate but not cuspidate in the single 

 £> now before the writer, though a $ nymph of what is apparently the same species 

 has the anteriorly projecting spine strongly developed. Eyes of moderate size ; 

 width of vertex a trifle more than one half of the longest diameter of eyes, slightly 

 advanced in front, broadly and shallowly sulcate and without a median carina save 

 at the extreme anterior edge. Face somewhat oblique and sinuate when viewed from 

 the side; frontal costa quite prominent between the antennae, sulcate, its greatest 

 width slightly more than that of basal antennal joint. Posterior femora robust and 

 uncommonly smooth even for the genus. Valves of the ovipositor short and slender. 



General color above uniform dark brown, almost black, the lower side, together 

 with legs, varied with dirty testaceous ; the anterior and middle tibiae annulate with 

 black — all the feet black-tipped. 



Length of body, i, 9 mm.; of pronotum, 8 mm.; of hind femora, 



5.5 mm.
