Female. Length 3-5 lines. — Black, shining and punctured, the 

 pubescence sparing and griseous ; on the face on each side of the 

 clypeus a little white pubescence ; the anterior margin of the 

 clypeus produced and forming an elevated flattened plate ; the fla- 

 gellum more or less rufo-piceous beneath. The thorax with a little 

 scattered pubescence on the sides and beneath, that on the legs 

 short and griseous, but dense and fulvous on the tarsi beneath ; the 

 calcaria pale testaceous ; wings subhyaline, their apical margins 

 clouded, the nervures black. Abdomen elongate-clavate, the apical 

 margins of the segments with narrow white pubescent fascia? ; 

 clothed beneath with pale fulvous pubescence. B.M. 



Male. Length 4-5 lines. — Black ; the face densely clothed with 

 fulvo-ochraceous pubescence ; the mandibles bidentate and fringed 

 beneath with long pale hairs ; the cheeks produced and forming a 

 blunt tubercle at the base of the mandibles ; the antennas filiform, 

 the flagellum, except the two basal joints, flavo-testaceous beneath. 

 Thorax with long, loose, very pale fulvous or cinereous pubescence ; 

 the wings as in the female. Abdomen cylindric, and thinly covered 

 with pale ochraceous pubescence ; the apex armed with two blunt 

 teeth. B.M. 



This is a very common insect in this country, appearing early in 

 June ; it is found throughout Europe, and is one of the true carpenter 

 bees. A closely allied species, C. nigricome, which occurs in Den- 

 mark, Sweden, and Prance, will probably be found in Xorth Britain, 

 and may be mixed with C. jiuns< nine in collections. The male of 

 C. nigricome has the antenna? entirely black and the joints simple ; 

 the apical segment deeply concave, its margin truncate, the lateral 

 angles being subdentate or acute ; the female wants the tubercle on 

 the clypeus. This short description will serve to identify the 

 species.
