Hab. Strawberry Valley, San Jacinto Mountains, Califor- 

 nia, 6000 ft., July 17 (F. Grinnell, Jr.}. 0. wilmattae Ckll. 

 (A variety with hair on inner side of hind tarsi; dark) was 

 taken by Mr. Grinnell in the San Gabriel Mountains, Califor-

Osmia pasadenae sp. nov. 



$ . Length a little over 8 mm., olive-green, the mesothorax more 

 bluish-green ; head and thorax with abundant long pale hair, which is 

 dorsally pale ochreous, lighter laterally, and white ventrally ; no dark- 

 hairs on head or thorax ; hair of abdomen and legs also all pale, without 

 any black, forming distinct through thin bands on segments 3 to 5 ; 

 hair on inner side of hind basitarsus pale orange ; antennae black, the 

 ftagellum slender, not at all moniliform; head and thorax very densely 

 punctured ; tegulse shining black ; wings dilute fuscous ; second s. in. long 

 and low, receiving first r. n. not twice as far from base as second from 

 apex ; legs (except hind coxae) not metallic ; tarsi ordinary, except that 

 hind basitarsus has a small tooth as in the subgenus Ceratosinia (to 

 which the insect is not otherwise closely allied) ; abdomen rather nar- 

 row ; sixth segment somewhat reflexed, and feebly emarginate ; seventh 

 bidentate, the teeth rath-er short and far apart ; first ventral segment ob- 

 tusely triangularly produced at apex ; margin of third ventral undulate. 



In general appearance similar to 0. inurbana Cresson, but 

 smaller, with a narrower abdomen, and readily distinguishable 

 by several structural characters above described. 



Hab. Pasadena, California, April 2, 1909 (F. Grinnell, Jr.). 

 0. olivacea Ckll. also has the tooth on the hind basitarsus, and 

 must be closely allied, but it is easily separated by the black 

 hair on the abdomen, etc. 



Also at Pasadena, April 8, 1909, Mr. Grinnell took O. ben- 

 nettae Ckll., new to California.
