14. Second and third tergites broadl.v black, red only on lateral portions of hind 



margins, pale color not extending entirely across posterior margin ; West 



Indies atricornis, new species 



Apex of first, all of second, and base of third tergite bright red ; United 

 States 15 



15. Eps 2 evenly and quite prominently convex, microscopically shagreened or 



alutaceous, and with very small isolated punctures (X 34), posterior part 



of eps 1 granulose, nowhere striate sayi (Rohwer) 



Eps 2 moderately coarsely longitudinally striate or punctato-striate 16 



16. Scutellum slightly alutaceous, not highly polished on disk and there rather 



uneven, the punctures quite large, deep, and isolated on each side, much 



closer and smaller on posterior margin littoralis, new species 



Scutellum not alutaceous, highly polished on disk, punctures smaller and 

 widely spaced except on posterior margin, where they are quite closely 

 placed texana, new species 



17. Femora and tibiae of all legs fulvous-yellow, the tarsi whitish yellow, all 



of first and second tergites of abdomen red, petiole castaneous, remainder 

 of abdomen glossy black, the apices of tergites brownish yellow; eps 2 

 coarsely punctato-striate, eps 1 not distinctly shining because of presence 

 of fine shagreening or alutaceous sculpturing, the punctures on upper part 

 large and contiguous, gradually becoming smaller and wider spaced 

 toward lower level ; prepectus vertically striato-punctate on upper part ; 

 propodeum coarsely rugoso-reticulate on entire dorsum and to a large 

 extent on sides ; space between occipital carina and one around mouth 

 not nearly so wide as first segment of fore tarsus seen from above ; hairs 



of face with a distinct golden tinge rufibasis, new species 



Femora and tibiae not entirely yellow, at least former and hind tibiae partly 

 black or dark brown ; first tergite at least largely black ; other char- 

 acters not as above in their entirety 18 



18. Intercarinal space in center of ventral surface of head as wide as first 



segment of fore tarsus seen from above 19 



Intercarinal space in center of ventral surface of head not nearly so wide 

 as first segment of fore tarsus seen from above 20 



19. Abdomen partly bright red, apex of second and usually all of third tergites 



red; fore and mid tibiae whitish yellow, more reddish yellow on anterior 

 and posterior surfaces, hind tibiae as usual, yellowish white on basal 

 third or less and dark brown or fuscous l)eyond ; mesopleiira with mod- 

 erately large shallow punctures, well separated on upper half of eps 1 



and more closely placed and smaller on eps 2 sufEusa (Fox) 



Abdomen glossy black, apices of teraites brownish yellow; all tibiae black, 

 fore pair whitish yellow on dorsal surface almost to apex and on almost 

 all of anterior surface, mid and hind pairs whitish yellow on basal third 

 or less; mesopleura with eps 2 closely punctato-striate, and upper part 

 of eps 1 coarsely subtransversely wrinkled and with a few large punc- 

 tures, the wrinkles fading out near midway to lower extremity and 

 replaced by rather large sparse shallow punctures. 



longiventris, new species 



20. Mesonotum coarsely and rather irregulaiMy rugnso-punctate, almost fur- 



rowed, especially on disk and anterior lateral angles ; mesopleura very 

 minutely shagreened, alutaceous, eps 2 with siiallow punctures and traces 

 of longitudinal wrinkles, eps 1 much more distinctly wrinkled and punc- 

 tured on upper half, sculpturing becoming fainter below ; propodeum
