 Bombus Lefebvrei, St. Farg. Hym. i. 461 [var. female). 

 One of the most genei'ally distributed and abundant species 

 of the genus: it has its representative in India, China, Japan 

 and Mexico ; indeed it is difficult to point out the specific dif- 

 ferences between them. I once saw a specimen of the beautiful 

 variety, B. Lefebvrei, in the possession of Mr. Wing, taken 

 near Sandwich, in Kent : the variety differs in having a yellow 

 collar, and it is remarkable that the parasite of B. lapidarius, 

 Apathus rupestris, sometimes exhibits a similar variation in 

 colouring : I never saw a British example, but have it from 

 the Continent. The nest of this species is frequently found 

 under stones ; in old stone-quarries in Yorkshire I have 

 repeatedly found it ; but it also occurs in banks, frequently 

 at the roots of trees : it defends its nest with great courage 

 and perseverance.

Var. y., female, and £., female. Var. /3,, neuter. 

 I forwarded specimens of this species to Denmark and 

 Sweden : Dahlbom, Schiodte and Boheman all told me that 

 the insect was not found in Sweden or Denmark, and all 

 named the female of B. Lucorura the Linnean Apis terrestris : 

 this information has long been published, notwithstanding 

 which Mr. Shuckard, in his recent work, repeats the error 

 into which so many have been led. Some hymenopterists 

 have thought the species " terrestris " and " Lucorum " were 

 mere varieties of one insect : this I am satisfied is erroneous,
