more deeply sinuated that in sinuata. Front longer and much narrower 

 above, the sides almost angled below, margins sharply reflexed, median 

 carina distinct, either side of which is an arcuated pale line simulating an 

 intermediate carina. Pronotum about as long as the vertex, strongly pro- 

 duced anteriorly in an obtuse angle between the eyes, the sides behind the 

 eyes very short. Scutellum with three parallel longitudinal carinae and an 

 abbreviated oblique one on either side which meet at the anterior end of the 

 median carina and are subparallel with the fore border of the pronotum. 

 Elytra surpassing the abdomen by nearly one half their length, almost 

 linear, the costa a little expanded near their base; inner ulnar nervure forked 

 beyond the middle, outer ulnar and radial nervures simple; transverse ner- 

 vures numerous, less so on the clavus and costal area, membrane more 

 irregularly reticulated. Legs short, posterior tibiae simple. Antennae short, 

 about as in Cixius; first joint very short, second longer, subglobose. 



Color light fulvous brown, sometimes darker on the front, middle of 

 the scutellum and elytra, the latter with the costal area and clavus pale, 

 apical margin and a spot beyond the tip of the clavus fuscous; carinae of the 

 face, pronotum and scutellum paler, apex of the clypeus, base of the second 

 antennal joint, a spot behind the eyes, sides of the genital pieces and tarsal 

 claws black; two transverse bands on the anterior femora, a longitudinal ray 

 on either side of the apex of the front and some marks on the abdomen dark 

 brown. Eyes dark brown or black; ocelli amber yellow. 



Described from numerous examples. This insect was abun- 

 dant everywhere on the island, especially on Lantana bushes. 

 It exhibits considerable variation in the depth of coloring but it 

 is quite distinct in its structural characters from Mexican 

 material I determine as Burmeister's sinuata, and from Canon 

 Fowler's figure of that species in the Biologia. I cannot find 

 that Burmeister's genus or species have either of them been 

 properly described and I have therefore included most of the 

 generic characters in the above description. Dr. Melichar now 

 places this genus in the Ricaniince. 



Subfamily Flatinae 



Amphiscepa plana n sp. 



Much smaller than bivittata. Of about the same shade of green over 

 the whole insect; a narrow dorsal line, sometimes almost obsolete, and the 

 costa slenderly pale or whitish; orbits of the eyes, ocelli and tip of the first 

 antennal joint whitish; tibiae toward their apex and the tarsi, a series of 

 concentric linear marks along the commissural and apical margins of the 

 elytra and the oviduct of the female, brown. 



Front longer and more nearly parallel above than in bivittata. Pro- 

 notum shorter at the sides and longer on the middle, anterior margin more 

 produced before, subconical and overlapping the base of the vertex, hind 

 margin almost truncated, not emarginate as in bivittata. Scutellum with 

 a small, abrupt and acute pale apex. Elytra narrower, costa not strongly
