SOME BEES FROM NEW MEXICO. 7 



Melecta interrwpta, Cresson. 

 Pecos ; at flowers of Falliigia, June 27th (M. Grahham). 



Antliidium porter (2, 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. 



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



Megachile emoryi, n. sp. 

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

 M. latimanas, 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 baud ; tegulae dark brown, 

 with extremely close but shallow punctures ; wings yellowish grey. 

 From M. sapeUonis, 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 hmd tarsi. 



Hab. 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 sapeUonis, 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 wootoni and calogaster. 



Megachile monardarum, Ckll. 

 Pecos ; male at flowers of Thelesperma gracile, Aug. 7th {W. 

 P. Cockercll) ; both sexes, Aug. Slst. This is the American 

 representative of M. tvillnghbiella, 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.
