Mus. Victoria, 20) is in general like the male, but the legs 

 are black, with red claws and creamy-white spurs. The 

 lower edge of the clypeus is straight and without tubercles, 

 a character separating it from the very similar M. derelicta, 

 Ckll. Ventral scopa white, fuscous at extreme apex ; dorsal 

 orange-ferruginous hair-patch covering fifth and sixth seg- 

 ments, except at sides, and extreme base of fifth. 



This is also very like M. Jieliophila, Ckll. ined., from Bris- 

 bane, but heliophila is about 12 mm. long and has the 

 mandibles coarsely strigate and sparsely punctured, while 

 those of ferox show three shining longitudinal ridges, with 

 channels between. The abdominal hair-patch of heliophila is 

 brownish golden rather than red. 



Meg achil e f rug alls, Cresson. 



Cresson described this form from a single male collected 

 in Texas. T have since received it from Southern California ; 

 a new locality is San Gabriel Mts., near Pasadena, 1750 ft., 

 July 15 (F. Grinnell). Thirteen males and ten females come 

 from Cotulla, Texas, nearly all ]\Iay 11 and 12, 1906 {Craw- 

 ford and Pratt) ; six females and one male are from flowers 

 of Parhinsonia, three females and nine males from Monarda 

 punctata, one female was on Verbesina enceUoides. 



A male was taken at Cotulla, March 27 {Jones and Pratt). 

 Seven females are from Devil's River, Texas, May 3 and 6, at 

 Monarda citriodora, collected by Y. C. Pratt. One female 

 is from Atoka, Indian Territory, at Asclepias tuherosa, col- 

 lected by ¥. C. Bishopp. 



The female is a comparatively narrow parallel-sided form 

 like the male ; it differs from M. inimica and heterodonta by 

 the minutely punctiired rugulose clypeus, which has the 

 anterior margin, excej^t at sides, thickened and shining. The 

 clypeus carries much erect black hair. The ventral scopa is 

 . white, with a faint creamy tint, black on the last segment. 

 In Priese's table {' Das Tierreich ') the female runs to 15, 

 but is quite distinct from M. addenda and pollicaris. Super- 

 ficially the female is very like M. verbesince, Ckll., but the 

 sculpture of the clypeus is entirely different. See also 

 'Canadian Entomologist,' Aug. 1903, p. 215. 



Megachile decipiens, Lovell and Cockerell. 



This species was described from two males collected in 

 Maine. I have before me two females from New Hampshire 

 (Littleton, C. M. Weed ; Hanover, C. M. Weed) which are,
