at apex ; gula scarcely indicated. Rostrum reaching hind coxse ; first seg- 

 ment attaining base of head. Basal segment of antennje scarcely surpassing 

 apex of head ; second almost as long as basal width of pronotum, a little 

 longer than third and fourth together ; fourth two thirds of third. Prono- 

 tum short, transverse ; its length two fifths its basal width, the sides a little 

 rounding to the anterior angles ; callosities narrow, well defined. Elytral 

 costa very slightly arcuated. Dextral male clasper elongated, obtuse, about 

 four times wider than long, just passing the middle of the genital segment ; 

 sinistral porrect, triangular, transversely convex. 



Color pale or whitish green, sometimes tinged with yellow on the head ; 

 the elytra subhyaline. Membrane whitish hyaline, highly iridescent; veins 

 pale green. Antennae slightly infuscated at apex. Tibise dotted with black, 

 these dots on the anterior and intermediate very small ; apex of tarsi 

 black. Upper surface clothed with soft white hairs. 



Described from one male and seven female examples taken 

 on willows along the Tahqiiitz trail in the village of Palm 

 Springs, Calif., May 21, 1917. This form may be distinguished 

 by its unifoiTn pale green color and spotted tibise. Its longer 

 head and uniform coloring will distinguish it from our other 

 species of Tuponia.

35. Tuponia dubiosa, new species 



Very close to lucida; smaller, proportionately broader and 

 more deeply colored ; light green, membrane immaculate ; hind 

 femora broader and more distinctly dotted, the tibial dots 

 smaller ; length 3 mm. 



Characters of head about as in lucida but with the vertex obviously nar- 

 rower ; basal segment of rostrum not passing the base of the head ; hind 

 femora broader than in lucida, subovate. 



Color more distinctly green than in lucida, more tinged with soiled 

 fulvous on the head and beneath, especially on hind femora and sides of 

 abdomen. Femora minutely but distinctly dotted with brown, the dots 

 on the anterior and intermediate sometimes almost obsolete ; tibise white, 

 the tibial spines pale, springing from minute black points which are much 

 smaller than in lucida. Membrane whitish hyaline, immaculate or appar- 

 ently so. Upper surface clothed with soft white hairs. Base of oviduct 

 infuscated. 



Described from six female examples taken on palo verde 

 at Coachella, Calif., May 16, 1917. Although very close to 

 lucida this form seems to be distinct by its smaller size, less 

 elongated form, deeper color, immaculate membrane and nearly 

 impunctate tibise.
