THE ENTOMOLOGIST. 207 



Bombus ignitus. — Female. Length 9 lines. Clothed with 

 black pubescence, the three apical segments of the abdomen 

 with vulb-fulvons. The head subovate ; the pubescence on 

 the margin of the vertex, on the posterior margin of the scu- 

 tellum, and on the apical margins of the two basal segments 

 of the abdomen, is sooty black ; the four apical joints of the 

 tarsi rufo-testaceous ; the wings subhyaline, with a broad 

 fuscous border to their apical margins ; the basal joint of the 

 tarsi clothed with short ferruginous pubescence beneath. 



There is a species from North China having the same- 

 coloured pubescence as B. ignitus, but it is much larger and 

 has dark fuscous wings ; the B. lapidarius of Europe is its 

 closest ally : from that species it differs in being altogether a 

 narrower insect, in the sooty fringes of the abdomen, and in 

 the much darker colour of its wings. 



Bombus tersatus. — Female. Length 10 lines. Clothed 

 with fulvous pubescence, that on the thorax with a rufo- 

 fulvous brightness. The head subelongaie, its pubescence 

 fulvous, intermixed with black below the insertion of the 

 antennae; the clypeus naked and shining, its anterior margin 

 fringed with bright fulvous hairs. The pubescence on the 

 body beneath is pale fulvous; the four apical joints of the 

 tarsi ferruginous; the claws of the apical joint black; the 

 tibia3 sprinkled outside with black hairs, the posterior pair 

 fringed with black and intermixed with a few fulvous hairs ; 

 the wings subhyaline, with their apical margins bordered 

 with fuscous. 



This species is very like the B. Smithianus from Shetland, 

 but that species has black pubescence beneath. 



Bombus diversus. — Female. Length 10 lines. Clothed 

 above with fulvo-ochraceous, beneath with black pubescence. 

 The head elongate ; the face, below the insertion of the 

 antennae, with thin erect black pubescence ; above the 

 insertion it is intermixed with short obscure fulvous, as it is 

 also on the cheeks ; the thorax above and on the sides, as 

 well as the three basal segments of the abdomen, clothed 

 with fulvo-ochraceous pubescence. The body beneath, as 

 well as the legs, have a black pubescence ; the apical seg- 

 ments of the abdomen are also clothed above with black ; the
