Protalebra unipuncta n. sp. — Length 3 

 mm. Resembling ««'tte//«e but larger. Head 

 very bluntlj angled in front, scarcely three 

 fourths the length of the pronotum. Head 

 and all below pale yeIlowi.sh, apex of the 

 former with a large, round black spot, vertex 

 brownish towards the base. Pronotum pale 

 golden brown, the hind margin narrowly 

 obscure whitish; in front of this whitish 

 margin, medially with two large oblong 

 black spots which diverge forward, on either 

 side of these is a small black spot; anteriorly 

 with a median blackish dash. Elytra golden 

 brown, an extensive costal area smoky sub- 

 hyaline, the apical veins whitish; a diagonal 

 white band extending from apical two-thirds 

 of clavus down and forward but a short dis- 

 tance on to corium, this band anteriorly mar- 

 gined with blackish. Clavus with two long- 

 itudinal Ijlack dashes, the outer shorter. 

 Female valve strongly rounded behind. 



Described from four specimens, male 

 and female, in the Herbert H. Smith 

 collection, taken at Chapada in January. 

 The four species, singularis., similis, 

 ninettae, and unipu7icta form a group 

 of very closely allied species. While 

 alike in general appearance, after the 

 manner, for instance, of Tettigotiia 

 r?ijipcs, l2-piiiictata, and crassa, or the 

 members of the colorata group, still 

 their dilVerences are striking and unmis- 

 takable. 



Protalebra vexillifera n. sp. — Length 3.5 

 mm. Vertex rather strongly but roundly 

 and almost tumidly angulate in front, the 

 vertex convex. Color very pale yellowish. 

 Peduncle of antennae, a median spot on an- 

 terior portion of pronotum, and a spot on 

 propleura extending up to hind angles of 

 pronotum, brick red. Pronotum posteriorly 

 ivory white. Scutel with a black band across 

 tip, leaving only a minute white point 

 beyond. Elytra with a bjoad white sub- 



diagonal band passing from middle of claval 

 commissure to costa, where it is refiexed and 

 extended diagonally upward and backward 

 to the transverse veinlets in a boot-shaped 

 white stripe; the transverse white band is 

 narrowly margined before with blackish, 

 beliind with sanguineus. Other than the 

 markings, the elytra are pale sordid yellow- 

 ish basally, becoming smoky subhyaline 

 apically. Inner apical cells with a large 

 whitish hyaline area. 



Described from one female and three 

 males in the Herbert H. Smith collec- 

 tion, taken at Chapada, Brazil, in 

 April. 



Protalebra tcrmitiata n. sp. — Length 3.5 

 miu. Vertex shorter than pronotum, rather 

 strongly but almost tumidly angulate, con- 

 vex above. Face rather tumitl and greatly 

 lengthened. Pronotum, head, and all be- 

 neath pale sordid yellowish. Two small 

 golden dashes on middle of pronotum, the 

 median line sometimes white. Elytra before 

 transverse veins whitish subhyaline marked 

 with golden; clavus with an irregular spot at 

 base and an incomplete circle at middle; 

 corium witli three equidistant, fine, trans- 

 verse, wavy lines. Beyond the transverse 

 veins, uniform deep, smoky in some cases, 

 in others this cloud is broken up more or 

 less by round hyaline spots. 



Described from four females and one 

 male in the Herbert H. Smith collec- 

 tion, taken at Chapada, Brazil in April. 



Protalebra amocna n. sp. — Length 3 mm. 

 Form much as in terminata. Pale yellowish, 

 vertex, a broad median portion of pronotum 

 and inner basal margins of elytral broaden- 

 ing to middle of claval commissure, washed 

 with sanguineous. Elytra hyaline with two | 

 golden clouds in region of brachial cell, 

 the apical one smaller and inclined to red- ] 

 dish. Liner apical margin of elytra irregu- .j 

 larly fuscous. 1
