watery secretion at regular intervals, three or four drops are emitted every 

 two or three seconds ; three drops every two seconds is a usual amount. 

 On June 23rd, after watching for two days at a time, during all hours of 

 day and night, two were at last found /// coitu. They were end to end, 

 and remained united for twenty hours. Although during several days 

 following, pairs were found connected and were watshed constantly, and 

 after separation the female was in some few cases isolated, and in others 

 left free and undisturbed, no signs of oviposition were ever indicated. 

 They were always quietly feeding or wandering from place to place, with, 

 apparently, no care but that of feeding, no aim but to rest. Gradually 

 they disappeared ; there is probably but a single brood in this locality. 



A NEW BEE IN THE GENUS DIPHAGLOSSA.

Spinola in 1851 described and figured Diphaglossa Gayi as a new 

 species and new genus closely related \.o Aiithophora. It was founded on 

 males and females collected in northern Chili, "Santa Rosa, Coquimbo, 

 etc." He figures the insect (natural size), face view of head and mouth- 

 parts, wing, antennas and leg. 



F. Smith in 1854 gave a partial description of the genus, probably not 

 from specimens, reporting the male only as known. He placed the genus 

 immediately after AntJiophora in his catalogue, and Dalle Torre in his 

 catalogue in 1896 has followed Spinola and Smith in placing the genus in 

 the Anthophoridce. 



In 1898, in a monograph of several closely related genera of bees 

 ( Afegacilissa, Caupolicana, Diphaglossa and Oxcea), Dr. H. Friese 

 regarded Diphaglossa as an offshoot of Megacilissa. which, according to 

 his view, hac been derived from Colletes through Caiipolicaiia. He had 

 examined males and females from " Santiago and Valdivia (Lossberg)," 

 and 6 females and i male from "Chili (Phillipj)i)," in the Vienna Museum. 



In his " Classification of the Bees," in 1899, Dr. \Vm H. Ashmead 

 placed the genus in the family Colletidic, citing most of its principal char- 

 acters in the generic table for the family.
