APIDJE. 



a narrower macula, the fourth a transverse fascia, the fifth, except 

 its extreme base, yellow ; beneath ferruginous, the apical margins 

 of the segments black, the fourth having a central yellow spot, 

 sometimes the third also. B.M. 



Yar. /3. The basal segment of the abdomen having two ferruginous 

 spots, which are sometimes united. 



Var. y. The anterior margin of the united spots on the basal seg- 

 ment yellow ; beneath variegated with yellow. 



Var. I. The ferruginous fascia having two yellow spots. 



Yar. e. The ferruginous fascia having a transverse subinterrupted 

 yellow line. 



Var. £. The tegulae more or less ferruginous, the red fascia obscure 

 and having two black dots. 



Male. Length 4-5 lines. — Black ; the face has a silvery- white pubes- 

 cence, that on the vertex and disk of the thorax pale fulvous : the 

 scape in front, the anterior margin of the clypeus, the labrum, and 

 mandibles yellow ; the flagellum ferruginous, three or four of the 

 basal joints fuscous above. Thorax — the tubercles and tegulte, also 

 sometimes two minute dots on the scutellum, yellow ; beneath, as 

 well as the coxae and femora, covered with a hoary pubescence ; the 

 femora, tibia?, and tarsi ferruginous, the former black at their base 

 beneath, and the posterior pair also black within ; wings as in the 

 other sex. Abdomen — the three basal segments having interrupted 

 yellow fasciae, the three apical fascia? uninterrupted, the seventh 

 segment yellow ; the fascia on the fourth segment attenuated in 

 the middle ; the three basal segments have the lateral yellow stripes 

 more or less pointed within ; beneath, the segments have trans- 

 verse broad yellow stripes. B.M. 



Var. /3. The apical margin of the basal segment of the abdomen fer- 

 ruginous, and having two yellow spots. 



This insect appears in May, and is generally distributed. The 

 female varies greatly both in coloration and size : the male seldom 

 varies ; it closely resembles the same sex of N. alternata, but it has 

 the legs variegated with yellow, and the tegulae of the wings bright 

 yellow. On examining Kirby's type specimens it becomes per- 

 fectly obvious that his Apis caprce and A. subcornuta are only small 

 varieties of N. lineola ; the names N. cornuta and N. subcornuta were 

 ill chosen, as the horn on the lip is common to so many species. 



21. Nomada sexfasciata. 



N. atra, scutello punctis duobus, abdominis segmentis tribus basali- 

 bus flavo maculatis, segmentis alteris flavo fasciatis. Has pedibus 

 flavis.
