532 Mr. T. D. A. Cockerell — Descriptions and 



somewhat larger, and has the basal band of the abdomen 

 entire. The scutellum brownish-haired (which is not at all 

 the case in ours), with its spots decidedly blue. 



Hah. Portuguese West Africa. Long. E. 15° 05', hit. S. 

 12° 4-4', alt. 13G0 metres above sea-level, at flowers of 

 jEoIanthus, Dec. 1906 (middle of rainy season) ; collected by 

 Dr. F, Creighton Wellnian. At the same flowers Dr. Wellman 

 also took a small (hardly over 8 mm. long) $ of C. meripes, 

 Vachal. 



Anthophora quadrt'fasciata (Villers), ? . 



Same locality as Crocisa Wellmani. Dr. Wellman notes : 

 " Stands motionless in the air like a bot-fly. Taken near a 

 flowering Convolvulus, but not actually seen in the flowers. 

 Its hum suggests a bottle fly." 



Anthophora convolvulif sp. n. 



9 . — Length about 12 mm. 



With mainly fulvous hair ; superficially looking exactly 

 like A. vestita, Smith, but differing as follows: — labrura 

 yellow (as in A. capensis, Friese), with a dark spot at each 

 basal corner ; mandibles yellow with the apex dark ; 

 clypeus with narrow anterior margin and a narrow median 

 band yellow ; a small supraclypeal mark ; hair of thorax 

 yellower ; hair on middle and hind basitarsi, except a tuft 

 posteriorly, black. The tegulse are clear red, and the hind 

 margins of the fulvous-haired abdominal segments, as in 

 vestita, appear pallid. 



Collected by Dr. AVellman in the same locality as Crocisa 

 Wellmani, in Dec. 1906, at flowers of Convolvulus. 



Apis nigritarum, Lepel. 



Dr. Wellman sent numerous workers from the same locality 

 as the Crocisa, &c., taken at various flowers, chiefly 

 Leguminosae. 



Agapostemon coloradensis, Crawford. 



The male, not hitherto described, was fouud by Mr. S. A. 

 Rohwer on the campus of the University of Colorado, at 

 Boulder, Oct. 3, 1906. It has the head and mesothorax 

 above blue, exactly as in A. californicus, but it is a larger 

 insect, and the yellow band on the clypeus sends upwards a 

 little projection in the middle. Abdomen with five yellow 

 bands, the first with a pair of black spots in the middle ;
