and tarsi, purpureo-fuscous on inner side of basal joint of anterior tarsi, 

 bright orange-ferruginous in the same position on the middle and hind 

 tarsi ; middle legs simple ; basal joint of hind tarsi flattened and con- 

 torted, with a large tooth on the anterior margin ; abdomen with erect 

 hair, entirely yellowish-white on the first two segments, sparser and black 

 on the others, with some long white hairs at the sides ; apical segment 

 strongly convex, bidentate, tomentose basally, with a slight longitudinal 

 keel ; venter with a band of light hair. 



Hab. One of each sex, collected May 17, 1892, by W. G. 

 Johnson on the campus of Stanford University, California. 

 The species is allied to A. boinboides, and would even better 

 merit the name than that insect. It is one of the finest and 

 most interesting bees in our fauna, and it seems remarkable 

 that it has so long remained undescribed. Prof. V. L,. Kellogg, 

 to whom I am indebted for the specimens, kindly gives me the 

 following information ; " I have, among other specimens, per- 

 haps two dozen taken from a single colony, the individual 

 nests of which were all put in close together. This colony 

 was situated in the side of a deep bank in somewhat sandj^ but 

 nevertheless very hard and compact soil. Each entrance was 

 capped by a long tube, two or three inches in length, made of 

 bits of soil stuck together, and bent down so as to make the 

 entrance obscure when looked at from above ; also so as to 

 protect the opening from falling water. The nest-tubes were 

 about one-half inch in diameter." (Litt, Nov. 20, 1903.) 



Megachile latimanus grindeliarum subsp. n. 



9 . Length 14 millim. ; the light pubescence yellowish throughout; 

 vertex and disc of mesothorax with much black hair (as in i/u'ndica), 

 but scutellum with yellowish hair ; abdominal bands weaker and nar- 

 rower (with shorter hair), yellowish-tinged, with the overlapping pale 

 orange hairs on the last two bands conspicuous ; the erect black hair 

 does not overlap the bands, nor does it project laterally (as it does in 

 monai'dariini} so as to be conspicuous at the sides when the abdomen is 

 viewed from above ; ventral scape orange throughout ; second recurrent 

 nervure ending very near to the second (morphologically third) trans- 

 verse-cubital ; hair on inner side of basal joint cf all the tarsi blight 

 orange ; apical dorsal segment of abdomen with erect yellowish bristles ; 

 abdomen perceptibly narrower than in laliiiiiimis.

 One at flowers of Grindelia squarrosa. Another, with denuded 

 mesothorax, from the same locality.
