Hah. Quirigua, Guatemala, at flowers of Zexmenia vir- 

 Ijulta, Klatt {IV. P. Cockerell, 42). 



Keiated to M. mexicana, Cress., and M. zapoteca, Cress. 

 From me.iicana it is known by the largely black hair on face 

 and the larger size ; from zapottca also by the size and the 

 colours of the ventral scopa. I was a little in doubt whether 

 to refer it to M, zapotecu, but after carefully reading 

 Cresson^s description 1 believe it must be distinct. 



Megachile tuxtla, Cresson. 



Male from Guatemala City (W. P. Cockerell) ; female 

 from Antigua, Guatemala [W. P. Cockerell). 



The female has not been described j it is like the male 

 except in the usual sexual characters ; clypeus with black 

 hair, but sides of face with Avliite; ventral scopa pale ferru- 

 ginous, becoming white basally, black on apical segment ; 

 abdomen broad, shovel-shaped ; hair on inner side of tarsi 

 very bright orange-ferruginous ; hind basitarsi only mode- 

 rately broadened. In Friese's table of females of the 

 Mexican region (' Das Tierreich,^ 28 Lief.) it runs nearest to 

 M. mexicana, Cress. 



At Antigua my wife also took a female M. chri/sophila, 

 Ckll.
