598 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.46. 



except a broad white band across apex of frons and gense and several 

 partially transverse white bands on frons — two near base, one midwaj-, 

 another not continuous near margin of apical white margin; several 

 white spots besides on vertex and frons; clypeus and forecoxse black; 

 antennae black at base, paler apically; legs pale, lineated with brown; 

 elytra (brachypterous) brow^l, veins whitish. Body stout. 



Head almost as broad as prothorax, carinas rather weak; vertex 

 longer than broad, rounded in front; frons subrectangular, median 

 carina forked about opposite ocelli. Antennae rather long, I less than 

 half as long as II. Lateral carinae of pronotum often curved out be- 

 hind eyes, not reaching hind margin. Elytra reaching to second ab- 

 dominal segment, veins prominent. Male genitalia similar to hakeri; 

 styles blunt at tip; anal tube processes very long. 



Described from one male and five females (brachypterous) from 

 Massachusetts and one macropterous male from-Arizona, one macrop- 

 terous female from Colorado (Cockerell), and two brachypterous fe- 

 males from Santa Clara County, California (Baker). The genital 

 characters of the western forms are slightly different from the east- 

 ern specimens, but I believe it is all the same species nevertheless. 

 The frons in the two California specimens is uniformly lighter in color, 

 though somewhat obscured. In most respects this corresponds very 

 closely with Van Duzee's brief description and I have no doubt it is 

 the same. 



DICRANOTROPIS BAKERI, new species. 



Plate 46, fig. N. 



Very similar to D. delicatus in proportions and color, differing 

 chiefly in male genitalia; processes of anal tube rather long, thick, 

 rounded at tip, directed outward; with a pair of slender acute stylets 

 between processes; genital styles larger and thicker than in delicatus. 



Described from a brachypterous pau' from San Marcos, Nicaragua 

 (Baker), and seven brachypterous females from Habana, Cuba 

 (Baker). This is very closely related to delicatus and further collect- 

 ing in intermediate localities may show that it is not specifically dis- 

 tinct. 



Type-specimen. — In collection of Pomona College. 



DICRANOTROPIS BAKERI ABDOMINALIS, new variety. 



Body a little larger than in species; vertex a little broader; frontal 

 carinae more distinct on apex of head; pronotum often nearly entirely 

 white or whitish, with median portion of scutellum concolorous with 

 it; elytra (macropterous) with a small black or brown area near tip 

 of clavus. Abdomen large, with a lighter and variegated area on 

 median two-thirds of dorsum, the rest brown. Male genitalia as in 

 species, except genital styles distinctly smaller and shorter, more 

 slender and acute.
