592 Insects. 



at their bases, the posterior are black beneath and behind at their 

 base : abdomen, the first segment has a rufous band, with two yellow 

 spots upon it, the second and third have acutely interrupted yellow 

 bands, the yellow spots being wedge-shaped, more or less margined 

 with rufous, the fourth has an entire fascia, and the fifth is entirely 

 yellow. 



Var. 1, (length 4 lines). The tooth on the lip obsolete, and also 

 the two yellow spots on the rufous fascia on the first abdominal seg- 

 ment. This variety is the Apis subcornuta of Kirby. 



Var 2, (length 4 lines). The rufous fascia on the first abdominal 

 segment reduced to two minute rufous spots ; the two yellow T spots 

 on the scutellum obsolete, the horn on the lip nearly so : the abdomen 

 beneath is piceous. This is the Apis Capreae of Kirby. 



Var. 3, (length 4j to 5j lines). This variety has the ferruginous 

 fascia on the first abdominal segment sometimes slightly interrupted, 

 sometimes entire, but without the yellow spots ; Kirby says, without 

 the horn on the lip, but in his own cabinet the specimen has it obso- 

 letely present ; the horn is a character which varies greatly. This 

 variety constitutes the Apis lineoldi, Kirby, and Nomada lineola, Panzer. 



Var. 4. With the two yellow spots on the first abdominal segment 

 united. 



Male, (length 4 to 5 J lines). Black : head, mandibles yellow r , tips 

 fuscous ; nose and scape of the antennae yellow in front, the remain- 

 ing joints rufous, with five or six of the basal ones stained, piceous 

 behind : the thorax has the tubercles, collar laterally, tegulae, and 

 sometimes two spots on the scutellum, yellow : legs rufous ; coxae 

 black ; the anterior and intermediate femora black at the base be- 

 neath, the posterior black, with a rufous line above, and also at their 

 apex ; all the tibiae are variegated with yellow : the abdomen has six 

 yellow bands, the first, second, and in rare instances the third, is in- 

 terrupted ; the segments beneath have yellow bands. This is the Apis 

 sex-cincta of Kirby. 



The female of this species is perhaps the most subject to variety in 

 its marking of any species in the genus : besides those enumerated, in- 

 termediate ones occur : a good selection of specimens alone proves the 

 range of variety. The male varies chiefly in the presence or absence 

 of the two yellow spots on the scutellum : it somewhat resembles the 

 same sex of Marshamella, but may be known by having the femora 

 more or less variegated with yellow, and by having more or less of 

 the number of joints of the antennae stained behind with black. It 

 appears in April and May.
