The wings are much darker than in 0. tristis, and there 

 arc other differences. 



Xoinia patloii), (Jkll. 



Ft dor, Toxa?, Oct. 18, 1897 {Birkmann). 

 New to Texas. 



Xomia norloni^ Cresson, var. plebeia, n. var. 



? . — The three abdo.ninal bands clear ferrun;inou3 instead 

 of green. Tiiis looks like a new species, but has the structure 

 of nortvni, and is surely only a variety. The type specimen 

 bears many mites, especially on the prothorax *. 



Hab. Fedor, Texas, June 18, 1905 {Birkmann). 



Typical iV. nortoni occurs at Fedor, visiting flowers of 

 mesquite, horse-mint, Polygonum, &c., as Mr. Birkmann 

 informs me. 



Nomia inaneei, sp. n. 



$ . — Length about 9 mm. 



Black, with green apical tegumentary bands on abdominal 

 segments 2 to 4 ; no trace of a green band on first segment, 

 but a patch ot white hair on each side, the rudiment of an 

 apical hair-band. This beautiful species has been confused 

 with JS'.foxii, from which it is readily separated thus : labial 

 palpi Avith joints 2 to 4 much longer; punctures of meso- 

 thorax well formed anteriorly ; middle of scutellum with 

 sparse punctures on a shining ground, and no little punctures 

 between; wings a little darker, b. n. meeting t.-m.; second 

 abdominal segment with smaller punctures ; third appearing 



* Disparipes texanns, sp. n. — Length 167, breadth 147 ^. Pale red, 

 shiny, anterior border of body broadly hyaline ; 8hape as in D. ameri- 

 canus, Banks, to which it is closely allied, but the following characters 

 are distinctive : large humeral bristles not so near the margin ; three 

 pairs of bristles on the .posterioi- margin, the intermediate j^ air slender, 

 the inner longer than the intermediate (these bristles rather variable) ; 

 two pairs of very large ventral abdominal bristles, the anterior pair more 

 laterad than the posterior; hind foot with a very long bii'stle in addition 

 to the shorter ones ; long subapical bristle of hind loot accompanied by a 

 shorter one ; first three pairs of legs very much more bristly than in 

 Banks's figure of D. americcmus ; sternal sclerites apparently longer in 

 proportion to their breadth ; claws much more robust, especially at base, 

 and much more strongly hooked, bent to less than a right angle ; clavate 

 organs behind anterior legs large and well developed, but not setiferuus 

 as figured for D. americayius. 



Hab. On Noviia nortoni, var. plebia, attached to the thoracic hairs ;
