tube large, produced on each side ventrad into a long tooth, anal 

 style small, short. 



Described from four males and one female; one from Acapulco, 

 Mexico (Baker), Arizona (Baker), and three from Jalapa, Mexico 

 (Crawford). In some respects this resembles 21. atrior, also a Mexican 

 species, but it diflFers sharply in several characters from Fowler's 

 description of that species. 



Type-specimen. — Cat. No. 15998, U.S.N.M. 



MEGAMELUS AURANTII, new species. 



Plate 48, figs. C, G. 



Average length, 2.4 mm. ; width of vertex, 0.16; width of frons, 0.19; 

 antennae, I, 0.09, II, 0.20. General color orange yellow throughout, 

 pronotum hghter; oceUi black; elytra flavous with tips of membrane 

 veins brown. Body rather slender. 



Head almost as broad as pro thorax, carinse rather pronounced; 

 vertex shghtly broader at base than beyond; frons rather narrow, 

 constricted between eyes, sides subparallel, about twice as long as 

 broad; antennae reaching about to clypeus, I scarcely half as long as 

 II, latter somewhat pubescent. Lateral carinae of pronotum straight, 

 usually extending nearly to hind margin. Legs moderately slender, 

 hind tibiae longer than femora; calcar rather long, thin, margui black, 

 finely dentate. Elytra slender, typical in venation. 



Male pygofers rather long, aperture elUptical, with a long, acute, 

 spiniform process on each side a little basal of midpoint and curved 

 inward over aperture; styles long, slender, enlarged at apex, not 

 strongly divergent; anal tube prominent, protruding caudad, with 

 one process on ventral margin. 



Described from one male and six females from Para, Brazil (Baker). 

 This is readily distinguished from related species by the long spini- 

 form processes on the margin of the pygofer aperture. 



Type-specimen. — In collection of Pomona College. 



MEGAMELUS ANDROMEDUS Van Duzee. 

 IdbumiaaTidromedaYAyi Duzee '07:46; '0.5:203. 

 One female of this species was collected in Belize, British Honduras, 

 by J. D. Johnson. Since there is no male before me I wiU not rede- 

 scribe the species. 



Locality. — Jamaica, Florida (Van Duzee). 



MEGAMELUS CULTUS Van Duzee. 

 Lihurnia culta Van Duzee '07:47. 

 This appears to be identical with peUucidus, but it is rather difficult 

 to be sure until the specimens have been examined. There is such a 

 wide variation in this species that it is scarcely advisable to create a 

 new species for two females only. 

 Locality. — Jamaica (Van Duzee).
