will be sent to me for study. Mr. Waterston also promises to send 

 many species from the British Museum, including- numerous forms 

 which Mr. Meade- Waldo intended to describe, and had carefully sepa- 

 rated for the purpose. The collection at Cambridge is small, though 

 there is a very fine British series from Doctor Perkins. There are 

 about two dozen Cameron ^ t^^pes, but the general policy at Cambridge 

 is to give holotypes to the British Museum. 



The important Indian collection obtained by Colonel Nurse, con- 

 taining many types, has gone to the British Museum ; but there re- 

 mained a very large duplicate series, which has been divided between 

 Oxford, the United States National Museum, and the American Mu- 

 seum of Natural History. Comparing the British Museum collection 

 with that of the United States National Museum, I have prepared 

 some statistics, of which the following are samples :

Megachile 



Stelis (including Chelynia) . . . 



Crocisa 



Nomada 



Perdita. 



Melipona (including Trigona).

These figures include only determined species. Races are included. 

 My own collection, which is very rich in species and types, will go 

 to the United States National Museum. After examining various 

 collections I am convinced that for a museum the system of card- 

 board trays used at Washington is vastly superior to any other and 

 should be adopted as widely as possible. 



BOMBUS ABBOTTI, new Bp«cies. 



Feinale. — Length about 17 mm., anterior wing 14.6 mm. A species 

 of the B. terrestris group, with short malar space (broader than 

 long) and entire mandibles. Black, with rather long abundant hair ; 

 ocelli small; third antenna! joint rather long; clypeus polished, with 

 very sparse punctures; hair of head entirely black; thorax with 

 creamy- white hair, but a very broad black band between the wings; 

 tegulae black; wings dilute brown; legs black, with mainly black 

 hair, but on tarsi it is pale reddish, as also at apex of anterior and 

 middle tibiae, while thfi long hairs fringing the hind tibiae are mixed 



» Cameron labeled all the specimens of his new species " type," and distributed them 

 to various museums. Hence one will find " types " of the same species in different 

 collections, no holotypes being designated.
