punctata^ but, in addition, each fresh flower contained a single bee. On 

 sorting out the bees after returning home, I was astonished to find 

 they were all of the genus Xe/iog/ossa, and included three species, viz.: 

 X. pruinosa, Say, 4 ^ ; X. patricia, n. sp., i $; X. cucurbit arum, n. sp., 

 3 $. X. patricia is nearest to X.fulva, but it is larger and stouter, 

 and the head and thorax are black. It has no resemblance to any of the 

 other species. Smith's Melissodes rubricata, from Oajaca, Mexico, is 

 coloured much like X. patricia ; may it perhaps ht a. Xenoglossa ? It 

 differs {rova patricia by the black pubescence on the legs, etc. 



Xenoglossa cucurbitaru/n, n. sp. — ^ . Length about 20 mm.; not so 

 stout as X. patricia ; black, thorax covered w^ith short orange fulvous 

 pubescence, legs bright chestnut-red. Head broad, orbits nearly parallel, 

 eyes black ; face, cheeks and occiput with rather thin pubescence, long 

 and fulvous on occiput, becoming whitish on cheeks and lower part of 

 face. Vertex more or less punctured, the punctures running into linear 

 grooves on the front. A shining channel descending from middle 

 ocellus. Ciypeus closely punctured, lemon-yellow, with its whole upper 

 margin and extreme sides rather broadly black, anterior edge rufous, 

 simple. Labrum yellow, with pubescence as in patricia. Mandibles 

 with a large yellow patch, the outer end of which becomes rufous. There 

 is a large, short tooth on the inner side of the mandibles, not far from the 

 base ; — this is wanting in patricia. Antennte reaching only to tegulfe, 

 piceous, scape and flagellum dark rufous; first joint of flagellum a little 

 longer than the two following together. TeguU^ reddish-testaceous. 

 Wings smoky, nervures piceous, venation as in patricia. Legs with 

 short reddish-fulvous pubescence, spurs rufous, claws black at ends, 

 strongly bifid. Abdomen black, shining, punctured, base of first segment 

 with fulvous hairs ; second segment at sides, and the other segments all 

 over, more or less covered with very short, appressed, fulvous pile. 

 Apex produced and truncate, much as in patricia. Sixth segment with 

 a tooth on each side. 



Habitat. — Mesilla, N. M., as described above. 



The following table will serve to separate the species oi Xenoglossa : — 



Legs, except the tarsi, black. 



Flagellum ferruginous or testaceous, at least beneath ; ^ with a 



transverse yellow band on ciypeus ipomcece, Rob. 



Flagellum black, or nearly so ; $ with a yellow spot on ciypeus, 

 sometimes wanting ; ^ with first joint of flagellum very 

 short prui?iosa, Say.
