PSYCHE. 



40J 



narrowly white, still below this on upper 

 part of front more broadly black. Face be- 

 low blackened, otherwise pale yellow, as are 

 also the legs except tips of tarsal joints 

 which are black. Sternum blackened. 



Elytra golden brown, faintly dotted with 

 paler; a spot at base of corium, a narrow 

 oblique line crossing elytra from apical third 

 of cerium down and back to costa, and apical 

 portions of second and third terminal ner- 

 vures, white. All apical and the two sub- 

 apical cells smoky subhyaline. Tlie elytra 

 in this species are very remarkable in that 

 they possess two anteapical cells, an occur- 

 rence unparalleled in the Typhlocybini, and 

 the three specimens I have are all alike in 

 this respect. Not only does the wing indi- 

 cate its true relationship, but the three very 

 closely allied species, si'milis, iiincttae and 

 nnipiincta, possess the normal elytral vena- 

 tion. 



Female valve with a stout, median, tri- 

 angular, black, margined tooth, the lateral 

 angles broadly rounded. 



Described from three specimeii.s in 

 tlie Herbert H. Smith collection, taken 

 at Chapada, Brazil, in April. Of these, 

 one has lost its abdomen, the other two 

 are male and female. The plane ver- 

 tex margined anteriorly with white and 

 black gives this species a striking re- 

 semblance to Scaphoideus. 



Protalebra similis n.sp. — Length 3 mm. 

 Closely resembling sitignlarh but smaller; 

 elytra without anteapical cell, and propor- 

 tionally shorter. Vertex, pronotuni and scu- 

 tel colored the same as in singularis except 

 somewhat brighter. Face, sternum and ven- 

 ter except last segment, blackish brown. 

 Elytra with general plan of coloration as in 

 sr/irr/ilarrs. Veins of clavus back of diagonal 

 white band black, this band on coriuin proxi- 

 mally margined with black. Cubital vein 

 black e.\cept for two small whitish interrup- 



tions, and costal cell apically with a diagonal 

 black spot. The golden brown portions of 

 basal half of elytra without the minute pale 

 dots found in suigularis. 



Described from three specimens in 

 tlie Herbert H. Smith collection, male 

 and female, taken at Corumba, Brazil, 

 in April. The reseitiblance to singu- 

 lari's is remarkable. 



Protalebra niueitae n. sp. — Lengtii 2.^ 

 mm. Form o{ siiigiilaris, but vertex sliglitly 

 convex, giving the head a somewhat tumid 

 appearance. Head pale yellowish, a large 

 round spot on tip.of vertex and one on either 

 side just below edge of vertex black ; lower 

 part of face bright sanguineous. Pronotum 

 orange, the hind maigin white bordered be- 

 fore with black as in strigitlaris, but the 

 black line extended forward on to the disc of 

 the pronotum in two large black teetli ; be- 

 tween these teeth white with a email black 

 spot. Scutel orange, the apical half white. 

 Costal and apical portions of elytra whitish 

 or smoky-subhyaline, a large spot at middle 

 of costal area, and the veins surrounding 

 outer apical cell, blackish. Rest of elytra 

 pale golden brown, with a white band reach- 

 ing from brachial nerve on one side across 

 apex of clavus to the brachial nerve on the 

 other side. This white band is not oblique, 

 and is bordered proximally with blackish, 

 the veins back of it blackish. 



Described from a unique specimen in 

 the Herbert H. Smith collection, taken 

 at Chapada in August. The species 

 of Protalebra are about the most deli- 

 cately beautiful Jassids I have ever 

 seen, not even excepting certain Tetti- 

 gonias, and this species is the gem of 

 the genus. On this account, I have 

 dedicated it to my wife, who has been 

 of the greatest assistance to me in my 

 scientific work.
