AMERICAN IIYMENOPTERA. 33 



sometimes obsoletely so ; the prothorax has the lateral and posterior 

 margins generally entirely yellow, sometimes the latter are indistinctly 

 so, while the anterior medial spot, which is generally distinct and trans- 

 verse, is sometimes reduced to a dot or entirely wanting ; the yellow 

 lateral margin of metathorax, the yellow band on apex of scutellum and 

 the yellow stripe beneath posterior wing, are distinct in all the speci- 

 mens before me, while the two yellow dots on disk of the mesothorax are 

 generally wanting; the posterior coxae varies from almost entirely 

 black to entirely ferruginous, and their femora have the basal and 

 apical spots sometimes much enlarged, while their teeth vary in num- 

 ber and size ; the abdominal markings vary but little, the lateral spot 

 on second segment of 9 i s sometimes wanting and the two stripes on 

 apex is sometimes much reduced ; while in the % the apical spot is 

 sometimes wanting; the ovipositor of 9 also varies slightly in length. 



Var. florirtana. — % 9 . — This has all the markings bright fiery ferruginous 

 or reddish-yellow instead of yellowish-white; apical half of flagellum black, 

 with the terminal joint dull ferruginous ; the head is without any metallic lus- 

 tre; the thoracic markings are all well-defined except the two discal marks on 

 mesothorax, which are subobsolete ; the wings are dark fuscous along costa; 

 posterior coxse almost entirely ferruginous, and their femora broadly reddish- 

 yellow at tips, or reddish with a discal fuscous spot, the teeth numerous and 

 minute, except the basal one, their tibiae orange-yellow; first segment of abdo- 

 men ferruginous, with a narrow reddish-yellow band before apex, apical mar- 

 gin black ; second segment immaculate ; the subapical band on third segment 

 rather narrow and regular, the two stripes on apical segment abbreviated, some- 

 times obsolete; the ovipositor attains the base of the abdomen. Length .45 in.

9. — Black, densely punctured, clothed with a short whitish sericeous pile; 

 face tinged with green and purple, vertex strongly so; extreme tips of antennse 

 fulvous, scape yellow ; a narrow band near posterior margin of prothorax, nar- 

 row lateral margin of mesothorax, a broader band on apex of scutellum, some- 

 times a narrow line on postscutellum, apical margin of metathorax, generally 

 interrupted, and a narrow oblique line on the flanks, all yellow; tegulse brown 

 or pale piceous ; wings more or less dusky, darker along costa and at apex; 

 legs black, sericeous, posterior coxse, their femora within and all the tibiae 

 within, more or less tinged with ferruginous ; posterior femora with a yellow 

 stripe on their basal half beneath, not quite reaching the base, the teeth mi- 

 nute, except the basal one which is broad and blunt, their tibiae with a yellow 

 stripe behind ; abdomen sericeous, first segment with a rather broad apical yel- 

 low band, the third segment with a narrow subapical yellow band behind which 

 is a sublunate yellow mark enclosing a smooth shallow brownish fovea, some- 

 times interrupted by it, apex with a broad yellow stripe, broader beneath and 

 divided by the ovipositor, which attains the apex of scutellum. Length .32 — .40
