SOME BEES FROM NEW BIEXICO. 7 



Melecta interrupta, Cresson. 

 Pecos ; at flowers of Fallugia, June 27th (M. Qrabham). 



Anthidiiim porter (g, Ckll., var. amahile, n. var. 



<? . Abdomen with the ground colour red instead of black ; the 

 yellow markings rather more developed, the abdominal bands very 

 little, some not, interrupted in the middle line. A very beautiful 

 variation, but in no sense a subspecies. 



Hah. Pecos, New Mexico, Aug. 29th, 1903. 



Megachile emoryi, n. sp. 

 5 . Length 18 mm. ; black, with the pubescence arranged as in 

 M. latimanm, but entirely orange ; the dorsum of thorax, except at 

 sides, bare, and as closely punctured as is possible throughout. This 

 looks like a gigantic M. latimanus, but in addition to its large size it 

 offers the following differences : pubescence more highly coloured ; 

 mandibles with the broad cutting edge presenting low crenulations in 

 place of distinct teeth ; sides of vertex more closely punctured ; eyes 

 in life black, with a broad green central band ; tegul^ dark brown, 

 with extremely close but shallow punctures ; wings yellowish grey. 

 From M. sapellonis, which resembles it in size, M. emoryi is easily 

 known by the straight and simple anterior edge of clypeus, orange 

 abdominal hair-bands, and extremely broad basal joint of hind tarsi. 



Hah. Pecos, New Mexico, on Kinkale Ranch, Aug. 31st, 1903. 

 It visits the flowers of the larger yellow-rayed Compositse. 

 Named after Lieut. Emory, who published an early account of 

 the region it inhabits. 



Megachile sapellonis, Ckll. 

 Pecos, Aug. 31st ; female. Eyes in life entirely black. 



Megachile wootoni, Ckll. 

 Pecos, Aug. 31st ; female. Eyes in life entirely black. The 

 specimen has black hair on vertex and mesothorax, breaking 

 down the distinction between ivootoni and calogaster. 



Megachile monardarum, Ckll. 

 Pecos ; male at flowers of Thelesperma gracile, Aug. 7th (IF. 

 P. Cockerell) ; both sexes, Aug. 31st. This is the American 

 representative of M. williighbiella, and in the male I cannot dis- 

 tinguish it from that species (cf. 'Psyche,' 1901, p. 283). Mr. 

 Viereck (Tr. Am. Ent. Soc. 1902, p. 48) has declared this species 

 to be identical with M. vidua, Smith. This is quite erroneous ; 

 M. vidua is the American representative of M. maritima. M. 

 monardarum has the eyes in life entirely black in the female ; 

 but sea-green, with the anterior margin broadly, the posterior 

 margin narrowly, and the upper third or fourth, black, in the 

 male.
