8. Me&onotal preescutum broadly edged with pale yellowish-white in 



front and on sides 9 



Mesonotal praescutum without a broad pale margin 12 



9. Wing membrane without numerous dots in the cells {subpectinata) . . 10 

 Wing membrane dotted with pale brown in all the cells 11 



10. Antennae yellow; head ochraceous-yellow pleural stripes narrow. 



subpectinata subpectinata Will.'' (Lesser Antilles). 



Antennae blackish; segments 12, 13, pale; head gray; pleural stripes 

 broad subpectinata pleuralis subsp. n. (Central America.) 



11. Antennae pale, e.Kcept segments 7, 8 and 14; a large oval brown spot 



at fork of media annulicornis End.''' (Trinidad, Colombia) 



Antennae dark brown, except segments 12-13; wings without a large 

 blotch as described above. . . .schwarzi sp. n. (Greater x^ntilles) 



12. Mesonotal praescutum without conspicuous dark brown marks, 



unicolorous except behind; wings abundantly dotted in all the 



cells miiltiguttata sp. n. (Central America). 



Mesonotal praescutum with darker longitudinal lines; wings with 

 markings large, scant3^ confined to the neighborhood of veins 

 (domestica) 13 



13. Thoracic praescutum with the middle stripes fused behind into a 



rectangular blotch. 



domestica angustifrons subsp. n. (Ecuador). 



Thoracic dorsum with a narrow stripe on either side of the pale 



ground line 14 



14. Larger (wing of male 5.7-6.5 mm.); color darker; wings tinged with 



brown domestica amazonensis subsp. n. (East Brazil). 



Smaller (wing of male 5.4 mm.); color lighter; wings almost hyaline. 

 domestica domestica 0-S.^ (Eastern U. S.; Central and Northern 

 S. America). 



The following species, known only from the females, could 

 not be included in the above key: R. bryanti Johns." (Eastern 

 U. S.), probably allied to maculata, but in its wing pattern suggest- 

 ing members of the domestica group; deflection of Cui unusually 

 far distad. It is a large, vigorous species, quite distinct from any 

 others that I have seen. R. tabescens End.'" (AVestern Brazil) 

 has a wing pattern very much like bryanti. It is quite impossible 

 to state with certainty the exact position of this insect. 

 Rhipidia calverti sp. n. 



Antennae with first eleven flagellar segments long bipectinate ; 

 pedicels of segments pale, whitish; thoracic pleurae with a dark 

 brown stripe ; tip of hinder tarsi golden-yellow ; wings subhyaline
