66. Sitalces trinitatis, new species. 



Rather above the medium in size, a little robust. Sides of head, lower edges of 

 pronotum and pleura to base of middle legs marked with a white line. The male 

 with a broad pale dorsal band and green legs. The female without the pale dorsal 

 band, the legs ferrugineo-testaceous, heavily conspersed with fuscous. Hind tibice 

 deep glaucous. 



Head a little wider than the front edge of the pronotum, eyes large and promi- 

 nent, aeneous ; vertex as broad as the first ( 9 ) or lne second ( $ ) antenna] joint, the 

 fastigium slightly depressed, blunt ; lateral foveolEe subquadrate, about the size and 

 just in front of the ocelli ; frontal costa prominent above, of nearly equal width, con- 

 tinuous and gently sulcate to the clypeus, coarsely punctate above the sulcus. Pro- 

 notum without lateral carina?, coarsely punctate, a little expanding on the posterior 

 lobe which is only half as long as the anterior one, the transverse sulci rather pro- 

 found, anterior edge truncate, the posterior edge of disk a little emarginate, lower 

 edges strongly sinuose. Tegmina spatulate, long and slender, quite ( $ ) or nearly 

 ( 9 ) reaching the hind margin of the first abdominal segment. Hind femora com- 

 paratively robust, reaching the apex of the abdomen in the female, or surpassing it in 

 the male by the length of the knees. Prosternal spine broad at base, the apex acumi- 

 nate. Hind tibi?e 8-spined in outer row. Legs and apex of abdomen hirsute. 



Head of male dirty white except a triangular patch on the occiput, sides of head 

 back of eyes, a little patch below each antenna and the lower margin of cheeks and 

 labrum which are deep brown or black. In the female the head is dark ferruginous 

 varied with fuscous save on the cheeks below where it is much paler. Palpi white. 

 Pronotum of the male deep chocolate brown except the pale dorsal stripe and lower 

 edges, becoming black immediately where joining the pale portions ; meso- and meta- 

 thorax siniilarly colored as is also the first abdominal segment ; segments 2-4 with 

 broad lateral black patches. Sides of metathorax with a narrow oblique white line. 

 Hind femora in male pale olive green, palest inside and below, the apical lunules alone 

 black or piceous ; in the female brownish testaceous with an oblique fuscous band on 

 outer face of basal half and some dusky marks along the carinae, inner face largely 

 black as are also the apical lunules. Sides of abdominal segments 2 to 4 less broadly 

 black than in the males.
