Aspect of seriatus but more brightly colored ; whitish, thickly- 

 sprinkled with bright croceus ; membrane irrorate ; length 

 3-3 y2 mm. 



Head short, projecting below the eye for a distance equal to the greatest 

 width of the eye ; clypeus broad, poorly distinguished. Antennae normal 

 for the genus ; first segment scarcely surpassing the apex of the head ; 

 second nearly equal to the basal width of the pronotum ; third and fourth 

 together not longer than second ; third one fourth longer than the fourth. 

 Pronotum short and broad, but slightly declinate ; its length two-fifths its 

 basal width ; sides feebly arcuate ; hind margin a little concavely arcuate ; 

 callosities small. Basal lobe of scutellum exposed ; costal margin of elytra 

 feebly arcuated. Hind femora broad, flattened. Dextral male clasper 

 long, curved and tapering, transverse, reaching across the genital segment ; 

 sinistral porrect, triangular, flattened, but little shorter than the dextral. 



Color testaceous-white ; upper surface closely sprinkled with rather large 

 orange dots, the disk of the cuneus quite strongly tinged with orange. 

 Membrane whitish hyaline, sparsely sprinkled with pale fuscous dots ; 

 veins and a large spot at apex of cuneus white, the latter bordered behind 

 by a fuscous cloud ; areoles infuscated about their margins, shading to 

 hyaline on their basal disk ; hind femora usually with a few dusky dots, 

 about three of which are larger and persistent. Tibiae armed with a few 

 stout bristles, posterior with a row of large black dots ; the anterior and 

 intermediate with a few small dots toward their base. Base of the female
