Columbia, and that of Peru. The Ecuador-Cohunbia coast region is 

 distinctly more humid than that of Peru. 



2. There is, so far as the materials before me show, a total absence 

 of precinctive genera; generically the fauna is nearly the same as 

 that of other parts of tropical South America, but it is interesting to 

 find at Guayaquil the characteristic southern genus Leptomctria meet- 

 ing the northern (Antilles and Eastern U. S.) Florilegus. 



3. The peculiar Chilian bee-fauna scarcely invades this region at 

 all, yet a very few species, such as Megachile cciiadoria, must be de- 

 rived from the Chilian group. The southern genus Lonchopria gets 

 as far north as ^latucana, Peru. 



Xylocopa brasilianorum bruesi new subspecies. 



Female. — Larger, length 28 mm. or rather more, anterior wings 23 mm. ; 

 abdomen above much more closely punctured. The wings have a fine rosy- 

 purple color, and are very dark. 



( 

 Habitat. — San Bartolome, Peru, July, 1913 (C T. Bnics). Three 



fema.les, all alike. 



Maidl (Ann. k. k. Xat. Hofm. Wien, 1912, p. 312) remarks at 

 length on the variability of X. brasilianorum, and gives a long list of 

 synonyms. Undoubtedly this type presents several different forms, 

 but specimens from any one locality are very uniform, and I believe 

 we have to do with subspecies rather than individual variations. 



Xylocopa transitoria Perez. 



Four females from Guayaquil, Ecuador, May-June, 1913 (Brues). 

 Maidl treats this as a synonym of X. brasilianorum, but it is cer- 

 tainly distinct by the truncate end of scutellum, and green wings 

 suffused with purple apically. A male from Guayaquil is apparently 

 X. brasilianorum, but has very distinct black bands on the hind 

 margins of abdominal segments, the extreme base of anterior tibiae 

 light yellow, and the dark clypeal patch very large. 



Females of X. morio callichlora Ckll. were also taken at Guaya- 

 quil. X. frontalis znridimicans Enderlein is a synonym of callichlora. 



Eulaema bruesi new species. 



Female. — Length about 20 mm.; superficially exactly like E. mussitans 

 (Fb.), but differing as follows: Third and fifth antennal joints considerably 

 shorter; labrum shorter; face on each side of antennae brilliant violet, below
