234 THE ENTOMOLOGIST. 



Bombus juxtus, Cresson. 

 Manitoii, Colo., April 28th, at flowers of Ribes lejJtantJmm ; 

 one female {T. d- W. Ckll). The second abdominal segment 

 has a small red patch, not mentioned in descriptions. A female 

 from Beulah, N. M., shows the same character. 



Bombus sonorus, Say. 

 San Pedro, California, July 8th, &c. ; common {Ckll.). New 

 to California. On July 20tb I found them freely visiting Datura 

 meteloides at 6.30 a.m.; they hunt for nectar, but are compelled 

 to crawl up the stamens to fly away, as they cannot well climb 

 up the smooth inner surface of the corolla. On July 10th I 

 found B. sonorus freely visiting the flowers of cultivated Ccesal- 

 pinia gilliesi. On July 9th I saw them visiting flowers of Abronia 

 umbellata, Ijo^m.^hwi remaining on them only a moment, and surely 

 not getting anything. The Abronia is adapted to Lepidoptera. 



Xylocopa varipuncta, Patton. 

 Los Angeles, Calif., July 22nd {CUL). At 7.20 a.m. I found 

 a female visiting Datura meteloides for pollen ; it hovered a good 

 while around the flower, and then alighted on the stamens. 



SpinoUella meliloti (Ckll.). 

 This was described from a single specimen. A second one, 

 agreeing with the type, was taken by Martin D. Cockerell at 

 Mesilla Park, New Mexico, May 20th. 



Dianthidium sticticum (Fabr.). 

 Mr. Vachal sends me an example of Antliidium sticticum from 

 Provence. I find that it belongs to Dianthidium. 



Anthophora euops, Ckll. 



Colorado Springs, Colo., April 25th, at flowers of Ribes 

 longiflorum ; female (IF. P. Cockerell); Manitou, Colo., April 

 28th, at flowers of Pdbes leptantJinm ; three males, one female 

 (T. d; W. Ckll.). New to. Colorado. The female, not before 

 known, is like the male, but has the face black ; the eyes are 

 green, as in the male. On May 10th my wife took males at 

 Colorado City, at flowers of Thermopsis arenosa and Ribes 

 longijiorum. 



Emphoropsis salriarum (Ckll.). 



Blue River, Arizona; one female {Dr. A. Davidson). Only 

 known previously from New Mexico. At the same place Dr. 

 Davidson collected a large example of Antkopliora urbana var. 

 alamosana (Ckll.), also new to Arizona. The two insects, 

 although of different genera, are extraordinarily alike ; aside 

 from the venation, the Emphoropsis may be distinguished by the 

 much less yellow tint of the thoracic hair, the much higher
