BEES IN THE COLLECTION OF THE U. S. NATIONAL 



MUSEUM. L

In all large museums, the entomological collections tend to accumu- 

 late faster than they can be worked up. New species may be col- 

 lected, and remain unstudied for many decades, and perhaps eventu- 

 ally be described from specimens captured many years later. Thus, 

 I have recently had occasion to work up some bees from Mexico in 

 the Berlin Museum, collected by Ferdinand Deppc as long ago as 

 1829. Several were still new, but others had been published in the 

 meanwhile by Cresson and myself. In the case of the United States 

 National Museum, the collections do not date so far back, but there 

 is nevertheless a quantity of valuable material among the bees, which 

 deserves to be described or reported. It will be the purpose of this 

 series of papers to discuss such portions of this material as may be 

 submitted to the present writer from time to time. 



In the descriptions of the venation the following abbreviations are 

 used: s. m. = submarginal cell ; r. ti. = recurrent nervure; t. c. = trans- 

 verse-cubital nervure; 6. 7i. = basal nervure; t. m. = transversomedial 

 nervure. 



CERATINA (CERATINIDIA) HIEROGLYPHIC A, var. JAPONIC A, new variety. 



Female. — Prothorax, including tubercles, entirely black. The 

 specimen is of the full size of liieroglypliica; the light reversed T on the 

 clypeus has the arms longer than the stem, and the latter is partly 

 divided into two parts by a median longitudinal black line; the lat- 

 eral face-marks are reduced to a longitudinal mark above and a 

 transverse mark below; the meso thorax has two slender discal lines, 

 and a short mark above each tegula; the scutellar patch is deeply 

 notched in front; the other markings call for no remark. Scape 

 entirely black. 



Habitat. — Japan (Koebele). C.liieroglyphica is quite variable, but 

 the mainland forms, including the Chinese var. morawitzii Stadel- 

 mann, always have yellow on the prothorax, so far as I know.
