legs with scopa strongly plumose, long and loose, wholly pale; hair 

 on inner side of hind tibiae fusco-ferruginous. 



In my table in Trans. Amer. Ent. Soc., XXXII, the female 

 runs to the vicinity of M. gilensis communis and hortivagans . It 

 is smaller than gilensis, with much clearer wings, and hair on 

 outer side of middle tibiae all pale (largely dark gray in gilensis). 

 The same characters at once separate it from hortivagans. The 

 wings are much paler and shorter than in communis, and the band 

 on middle of second abdominal segment is much broader. The 

 hind margin of fourth abdominal segment has dark hair only in 

 middle, not right accross as in M. wheeleri. Among Robertson's 

 species M. semiagilis female resembles M. vernonice, which has 

 short, still clearer wings; but vernonice has a patch of black hair 

 on outer side of middle tibiae apically, the hair on abdomen 

 whiter, and the hair on inner side of hind basitarsi black. 



Hab. — Quanah, Indian Territory, at flowers of Helianthus, 

 June 10, 1906 (/. D. Mitchell), U.S. Nat. Museum, 9d\ 49. A 

 female from Dallas, Texas, at Helianthus, Sept. 22, 1905 (F. C. 

 Bislwpp) has a little dusky hair at apex of middle tibiae, and the 

 hair on inner side of hind basitarsi is fuscous; but the general 

 appearance and colour of the hair agrees exactly with semiagilis, not 

 with vernonice. Thus it rather approaches M. simillima Rob.

o 71 . Differs from a cotype in having the flagellum only 

 obscurely reddened (instead of bright clear ferruginous) beneath; 

 otherwise normal.

Melissodes bishoppi sp. n. 

 o 71 . Runs in my table in Trans. Amer, Ent. Soc, XXXII, to 

 the vicinity of M. aurigenia Cresson, which it closely resembles 

 differing as follows: Third antennal joint (view from front) 192 

 /j. long, fourth 752 (the same measurements for aurigenia are 128 

 and 1040); the third joint very much longer than second; 

 flagellum about 53^ mm. long (about 73^ in aurigenia) ; nervures 

 darker; second s. m. narrower; third t. c. angular in middle;
