Ilah. Southern California, Mt. Wilson {Davidson). Also 

 on Mt. Wilson, Dr. Davidson took that remarkable species 

 A. cleodora, Viereck, hitherto only known from Oref^^on 

 {cf. Canad. Entom. 1904, p. 161). 



The new subspecies is named after Mr. IL C. Fall, the 

 Coleopterist of Pasadena, California. 



Nomada Educe, sp. n.

 or not quite 8 mm.

 and thorax very hairy, the hair light fulvous ; vertex and 

 raesothorax dull and densely punctured ; eyes in life grecMiish 

 grey, delicately suffused with red, especially above ; maxillary 

 palpi long; head broad; mandibles simple; clypeus not 

 hairy, but supraclypeal region very hairy; clypeus, broad 

 lateral corners of face, extending narrowly up the orbital 

 margins nearly to level of antennae, a mark beneath eyes 

 behind, labrum and basal two thirds of mandibles, all yellow.

 ill front; flagellum bright ferruginous, its first four joints 

 M'itii a large black mark above, that on first narrower than 

 on the others; last joint normal; second antennal joint 

 sunken into apex of scape ; third joint much shorter than 

 fourth ; prothorax above, tubercles, patch on lower part of

 broadly red, those of 1 and 2 infuscated ; apical plate 

 notched ; venter red, banded with yellow. 



A species of the Xanthidhan group, which runs in my 

 table of E-ocky Mountain Nomada (Bull. 94, Colorado Exp. 

 Station) to 47, and runs out because of the comparatively- 

 large size and notched apical plate. It has a strong super- 

 ficial resemblance to A'^. orm'tliica, Ckll., but that is much less 

 hairy, and differs in the colour of the legs &c. Among th«
