Protalebra bifasciata Gillette. 



(Proc. U. S. Nat. Mus. xx. p. 711, 1898.) 



I took one example of this very distinct little species at 

 Rock Fort on March 25th. This has the black spot on the 

 scutellum and base of the clavus very intense but narrow, not 

 reaching more than half way to the costa. The types were 

 from Brazil. 



Protalebra omega n. sp. 



Near vexillifera Baker. Smaller than apicalis; marked with white, 

 orange and golden brown. Vertex quite convex and strongly produced, 

 whitish with two approximate points behind the apex and a large discal spot 

 dusky. Pronotum milk-white; a large oval orange spot occupies the apex 

 anteriorly, deflected sides behind the eyes including the humeral angles 

 reddish orange. Scutellum fulvous at base, whitish at apex, with the 

 slender edges and apex minutely black. Elytra light golden brown with a 

 broad curved milk-white vitta beginning on the claval commissure just 

 behind the tip of the scutellum, touching the costa at about its middle, and 

 then deflected inwardly and backwardly where it becomes narrower and ter- 

 minates just before the middle of the transverse nervures. This white vitta 

 is slenderly bordered with black exteriorly at base and with fuscous within 

 and exteriorly at apex, and with the elytra closed forms a conspicuous and 

 almost perfect mark the shape of the Greek letter omega; Apical areoles 

 hyaline, a little smoky at tip and bordered costally by a curved fuscous 

 marginal vitta which is deepened to a black spot on the node. Beneath and 

 legs whitish; the posterior tibiae, dotted with black. Last ventral segment 

 of the female strongly triangularly produced almost to the middle of the 

 pygofers, the latter with stout black and white bristles. Length about 2 mm. 



Described from two female examples taken at Rock Fort, 

 March 25th. This is a small but very pretty species that must 

 be related to vexillifera of Baker, but it is quite distinct. 



Protalebra octolineata Baker. (Invert. Pacifica, i, p. 7, 1903.) 

 Two males and two females of this neat little species were 

 taken at Rock Fort at Kingston. I also found it in numbers on 

 Lantana bushes along the path to the office of the Hope Gar- 

 dens. In my examples the vertex is soiled yellowish with the 

 median line darker; a line either side of this and another ad- 

 joining each eye paler. The common dark median line of the 

 pronotum and scutellum is bordered on either side by paler; 

 anterior submargin of the pronotum with a narrow pale yellow 

 callous and there is a smaller one behind each eye; the calloused 

 slender lateral edges whitish. The four parallel slender black 

 lines on the elytra are well described by Baker but he fails to 

 say that the included area between them is whitish hyaline
